As a bandwidth provider, UUNET is more concerned with aggregate throughput; this means it cares more about the moving average of packets getting through than it does about *my* packets getting through.

Yes, I'm well aware of bandwidth delay product calculations; it's the primary mechanism behind the rate halving algorithm I keep pointing to (Hoe, Jacobson). 8-). It's also the primary limitation on connection speed (remember that it was my FreeBSD machine that was able to get to 1.6M connections, with standard sockets). > Likewise, the original problem in this thread is likely caused by some > part of the USB Ethernet implementation having inadequate per-packet > resources.

It was absolutely repeatable. Clearly. I think that's well established, since no one has squawked about the FreeBSD USB driver or the PC USB hardware being slower than the dongle USB hardware... > Sure, it's "legal" to generate streams of tinygrams and not use Nagle's > algorithm to aggregate the sender's traffic, but it's just plain rude > and on low bandwidth links, it sucks because of all the extra 40 byte > headers you're carrying around. I understand this. But Nagle is not the only mechanism which would fix the problem. Given that it's *intentionally* possible *and permitted* to turn Nagle off (via TCP_NODELAY), it makes sense to look at another mechanism that is not succeptible to being turned off. > I'm sure TCP_NODELAY got added because it sounds REALLY C00L to make > the interactive thing go better. But clearly people don't understand > the impact of turning on the cleverly named option and how it probably > doesn't really improve things. I'm pretty sure it got added to address interactive response on intrinsically small packets; telnet was probably the number one reason, but interactive responsiveness of small requests over TCP, such as non-pipelined HTTP requests, SMTP server responses, FTP control channel traffic, and other protocols benefit significantly from turning Nagle off. Nagle almost suggests it, in the original paper. Since OpenSSH incredibly bloats payload, it's much less necessary to get performance as it would be out of Telnet, though you will likely see least common multiples of the MTU cause occasionaly burstiness. Probably in this case, it would make sense to increase the decay rate of the timer based on the amount of data that is pending, relative to the MTU: defeat Nagle when the pipe is full, and partially defeat it down to, say, the pipe being half full. Thus large streams not ending on MTU boundaries would not suffer under Nagle. Remember also that Matt recently shot Reno for performance reasons, when compared to Linux, when he should probably have simply cranked initial window size to 3 (Jacobson) and added piggy-back ACKs (Mogul). While I'm sure the shooting is actually temporary, and eventually it will end up back on, once the performance issue is addressed correctly, realize that there is heavy pressure in the form of benchmarks to deal with, where speed is more important. In fact, until Windows 2000 (which has a BSDI ported stack that cost them ~$3M in fees), the Microsoft stacks routinely violated the RFCs on connection closing using RSTs to avoid the FIN_WAIT_2 issue, while at the same time potentially leaving the peer stuck forever (since RSTs are not retransmitted); you still have to set a registry entry to get correct behaviour, even today. I think with much faster links becoming common (802.11e is 5GHz over the air [Apple Trademark "GigaWire"]), we will see the MSL drop significantly; we already have problems with sequence number recycling with the random jump forward for "security" purposes to avoid session take-over -- even though we all know that end-to-end doctorine means that security is not correctly handled, if implemented at that layer. 2MSL is already incredibly huge, compared to the cycle time for 32bit sequence numbers on a 1Gbit link. I really like the self-clocking in the rate halving algorithm, but I guess that's pretty obvious by now. 8-). -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Tue Jan 1 5:27:51 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from swan.prod.itd.earthlink.net (swan.mail.pas.earthlink.net [207.217.120.123]) by hub.freebsd.org (Postfix) with ESMTP id 2118D37B43A for ; Tue, 1 Jan 2002 05:27:46 -0800 (PST) Received: from pool0063.cvx40-bradley.dialup.earthlink.net ([216.244.42.63] helo=mindspring.com) by swan.prod.itd.earthlink.net with esmtp (Exim 3.33 #1) id 16LOx8-0003tU-00; Tue, 01 Jan 2002 05:27:39 -0800 Message-ID: <3C31B94A.15BDD42F@mindspring.com> Date: Tue, 01 Jan 2002 05:27:38 -0800 From: Terry Lambert X-Mailer: Mozilla 4.7 [en]C-CCK-MCD {Sony} (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: "M.

My experience agrees with David's. It makes sense to set TCP_NODELAY on the client, still, if the payload is still small enough after encryption. On the server side, it makes less sense. The server side TCP_NODELAY is the problem in this case, since it is the client, not the server, which is on the slow side of a USB dongle, FWIW. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Tue Jan 1 6:31: 4 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from artemis.drwilco.net (artemis.drwilco.net [209.167.6.62]) by hub.freebsd.org (Postfix) with ESMTP id 0F3FB37B42F for ; Tue, 1 Jan 2002 06:31:00 -0800 (PST) Received: from ceres.drwilco.net (docwilco.xs4all.nl [213.84.68.230]) by artemis.drwilco.net (8.11.6/8.11.6) with ESMTP id g01EUqR36334 (using TLSv1/SSLv3 with cipher DES-CBC3-SHA (168 bits) verified NO) for ; Tue, 1 Jan 2002 09:30:55 -0500 (EST) (envelope-from drwilco@drwilco.net) Message-Id: <5.1.0.14.0.20020101153934.01de0038@mail.drwilco.net> X-Sender: lists@mail.drwilco.net X-Mailer: QUALCOMM Windows Eudora Version 5.1 Date: Tue, 01 Jan 2002 15:39:41 +0100 To: freebsd-hackers@freebsd.org From: "Rogier R.

I got some good answers (thank you), but now I have one more question. From the 27/12 too the 29/12 I was at the CCC congress and attended a lecture called "Unix Redesigned". It was Neal H Walfield who talked about The Hurd: http://www.gnu.org/software/hurd http://www.debian.org/ports/hurd So my question is: Will FreeBSD take a good look at the Hurd? I know the last Hurd release was in 1997, but within this year a new release will be made. I don't expect FreeBSD to rewrite the whole kernel, but just too use some of the things or make a combination. Fx now users can have more id's and deamons run as "null".

I tried the Hurd in 1999 and wasn't very impressed, just downloaded the H2 ISO but haven't tried it yet. The only thing that makes the Hurd look like Unix is the POSIX compat layer. The advantages of a microkernel vs (pseudo) monolothic are well known, as well as disadvantages. Of course I can't speak for the FreeBSD developers but IMHO there's very little, if anything, that can be taken from Hurd and imported into FreeBSD (or Unix in general). Yes, you can ran a BSD server on top of Mach (MacOS X) but it's not the same as Hurd does. I would find it far more interesting to take some Plan9 ideas than the ones that could be taken from Hurd. It seems like the only reason that project is alive is to satisfy RMS' ego :-) Err, did I say that? Nervermind.

Rafter Man wrote: > [Whether FreeBSD does or will take ideas and features > from Hurd] I think the FreeBSD developers are well aware of useful things in many other operating systems. In today's world, you cannot successfully write a general-purpose operating system without looking at the other players. This includes the guys from the UNIX camp (Solaris, Linux), but also others, even Windows. (If everything else fails, Windows can at least be used as an example of how to _not_ do things.) If Hurd has something useful to share, then why not? Wether a certain feature will be adopted depends on a lot of things, though. First of all, there has to be someone willing to learn and spend time writing code. This is probably the biggest problem for a free open-source project: manpower. And I don't mean people who want to "code something up for fun", but people who are willing to work hard and do things that are not necessarily fun, such as reading dusty papers, learn how to use existing interfaces, reading and adhering to style guides that don't match your own style, writing documentation (manpages) etc. Just out of curiosity: Which particular features of Hurd would you like to see incorporated in FreeBSD? If you can name them, they could be discussed, and maybe someone even picks them up and actually does something. Another possibility is to file a PR (feature request), but you should only do that if you're really sure that FreeBSD does not already have the feature in question or something equivalent. > Fx now users can have more id's and deamons run as "null". I'm sorry I don't quite understand. If you mean that the number of processes that a user is allowed to run can be limited: You can already do that in FreeBSD. You might want to read the login.conf(5) manpage, and particularly the "resource limits" section.

Hurd, as I know, derived some of it's code from the Mach program. And so does FreeBSD with it's VM (and I don't know what else). I don't see why FreeBSD should support Hurd, etc. Hurd is a micro-kernel based system, and quite a significant portion of the code would need to be rewritten to make portions of FreeBSD and Hurd to be intermixed. Leave aside performance improvements and stability issues. I also cannot see the logic in continuation of the Hurd - we don't want more OSes or kernels or bells and whistles - we just want better stuff; ones that will keep pace with the improvements in hardware capabilities. Like FreeBSD and Linux. Also, licensing is an issue - majority of the the Hurd source code carries the GPL (and the CMU and Utah licenses too, if I'm not wrong). GPL conflicts with FreeBSD's artistic license. And finally, IIRC, there is already a project called xMach, which is AFAIK a derivative of both FreeBSD and Mach (somebody please correct me).

Your focus appears to be on security, so you should really look at the POSIX 1e effors currently underway in the FreeBSD community. However, I'll try to be more general... Hurd is a multiserver running on top of MACH. FreeBSD already has an unencumbered single server version that runs on top of MACH, and MAC OS X is already a multiserver implementation. As a general comment, MACH is a dead horse. The problem is that it contains significantly more protection domain crossing than it should in order to communicate between OS components, and for each crossing, you pay a hefty penalty. During develeopement, it would be useful to have the ability to seperate the component you are developing into its own address space, but really, Chorus is a better model. Though 4G RAM machines are increasingly common, statistical memory protection approaches are still quite valid for doing this type of work on 64 bit architectures: even with a full 4G of RAM, program only have a 1 in 4 billion chance of finding a valid byte of memory through random accident. So despite the fact that I am quite impressed with MAC OS X, it is really somewhat of a blind alley, according to current work in CS. I think a much better project to learn from would be "Choices": http://choices.cs.uiuc.edu/ There are also several lesser known capabilities-based OS projects (the license on them is commercially restricted), and they are capable of dealing with the Capabilities Security Model bootstrap process, and are self checkpointing to the extent that you could "have your dog kick out the plug, plug the machine in again, and be up and running where you were in a matter of seconds". At one point in time, John Dyson, the original author of the FreeBSD unified VM and buffer cache code (not to belittle the excellent work done by Matt, Alfred, and others) was talking about a project to write a drop-in-replacement SMP kernel that was designed for SMP from the ground up. I personally never joined this effort, because John wanted to "cop out" on doing kernel preemption, which is necessary for hard real time, and for high granularity SMP and node migration of processes (for example, in a NUMA cluster, rather than an Intel model SMP system). I think that many of us are aware and up to date on the most recent research. In fact, I would say that there are a fair number of us who believe that FreeBSD is about a decade and a half or more behind the state of the art; but since there is not an infinite amount of time, and we have day jobs, we can't "fix everything" over night. There are some lessons that can be taken from HURD, but there are other projects and products which have already taken those lessons, and pushed them much farther than HURD has considered pushing them.

I need an NFS server with 4G ram. When I boot a 4.5-PRE kernel it panics during the boot process, not always at the same place though. My first instinct is bad hardware because of the lack of consistency in panic location, however I was wondering if there were some issues with kernel tuning for machines with large memory that I should be aware of. This machine boots OK with 3G or less. Here is a trace and panic with kernel config etc... So... hardware or kernel config or kernel bug???

    ShareCom, Inc. Ships the First NOAA = Weather Radio Featuring Instant Localized Setup

    PALATINE, Ill.--(BUSINESS WIRE)--Dec. 11, 2001--ShareCom, In= c.(TM), the market leader in designing and manufacturing NOAA (National Oceanographic and Atmospheric Administration) Weather Radi= o and Disaster Readiness electronics products, today announced availabilit= y of its WRP-500 Broadcaster(TM) NOAA Weather Radio, with an SRP of= $149.99, available for purchase via its ecommerce web site and through se= lect retailers around the country. Like all ShareCom products, the WRP-500= features a streamlined and fashionable design, coupled with strong price = performance.

    ShareCom manufactures products which are expressly d= esigned to support the in-place NOAA Weather Network - an always on (24/7)= broadcast network that covers 95% of the US. This ``early warning'= ' network provides general-purpose weather information and alerts for haza= rdous weather or disaster warnings for people throughout the US.

    = The Federal Government, The Americ= an Red Cross and numerous state and local government agencies a= re now emphasizing the need for the NOAA Weather Radio network, especially= since the September 11th tragedy. A NOAA Weather Radio is now consi= dered as important as having a smoke detector in a home, school or busines= s.

    ``Our market research in= dicated a strong need in the marketplace for a NOAA Weather Radio that loo= ks good in someone's home or office, but that has real ease of use built i= nto the overall design,'' said Brad Nordling the CEO of ShareCom, Inc. ``O= ne of the most requested feature enhancements from our consumers has been = to provide functionality that enables them to setup a radio right out of t= he box, with no cumbersome interface to deal with. The WRP-500 Broadcaster= addresses this need by incorporating our Graphical Alert Technology(TM) s= pecialty software - our customers now have the ability to easily config= ure their radios in a matter of seconds using a functional scroll down men= u.''

More Reasons to Consider Buyin= g SHCC

1.= WeatherRadios.com has been awar= ded a National Partnership with the Federal Emergency Management Agency (F= EMA) to increase the use of Weather Radios country wide through a = program called Project Impact. There are 2,600 Project Impact communities = in the U.S. The FEMA web site lists WeatherRadios.com as a national partne= r providing a banner and link to the WeatherRadios.com site. The FEMA site= receives over 100,000 visitors per day. 

2. The Nat= ional Oceanic and Aerospace Administration (NOAA) has WeatherRadio= s.com listed first on their web site, telling people were to purchase a NO= AA Weather Radio. 

3. The National Weather Serv= ice (NWS) has offered to promote corporate sponsorships to the Wea= therRadios.com site through recognition and media support.  &nbs= p;

4. Local American Red Cross Chapters will promo= te NOAA Weather Radios through WeatherRadios.com in an exchange fo= r a $5.00 donation per radio sold. 

5. The Chicago= Area AAA will feature SHCC's 2WayTalk.com on its web site offering exclusive discounts on Weather Radios,= and FRS Family Radios. 2WayTalk.com will also be listed in the AAA magazi= ne called "Home and Away". 

6. The Federation of Manufactured Home Owners of Florid= a (FMO) has entered into a one year agreement that will increase t= he sale of Weather Radios from the WeatherRadios.com site. Mailings and we= b site links will offer a group discount to members and also pay a rebate = to the organization for every radio sold. 

7. The Owner - Operat= or Independent Drivers Association (OOIDA) has begun to promote th= e discount that is offered through the WeatherRadios.com site. Magazine ar= ticles, mailings, and web site links will offer a group discount to member= s and also pay a rebate to the organization for every radio sold. This agr= eement will run for one year. 

     NOAA Weather Radios automatically alert people of impending severe weather conditions &= quot;24/7". This is especially critical for families while sleeping. = These devices are fast becoming recognized as essential and pote= ntially life saving for use in homes, businesses, and critical care fa= cilities.

The National Weather Service (NWS)<= /font> has stated that t= here has been an increase in severe weather in the last 10 years and this = trend is expected to continue. NWS has a published goal for NOAA Weathe= r Radios to be in every home within the next 10 years. Currentl= y, approximately just 7% of homes have this device. This being said= , we can expect a tremendous increase in the presence and sale of weath= er radios over the coming years. The NWS, NOAA, the Federal Emergency = Management Agency (FEMA) and other government agencies have an aggressive = education and funding effort to reach the 100% goal.

New technology called Specific Area Mess= age Encoding (SAME) was introduced in the mid 90s. It allows users to set = an alarm only for their specific geographic area. This feature is expected= to make this tool commonplace in homes alerting families of weathe= r conditions that pose an immediate danger.

Additionally, 2Wa= yTalk.com will continue to focus on Internet users who are outdoor enthusi= asts. The market continues to be strong and growing. FRS Family Radios are= now becoming a popular family item on vacations, ski trips, camping, and = biking events. They are used for a wide variety of purposes, from staying = in touch with children playing in the neighborhood, to coordinating soccer= tournaments and antique auctions. 

A Final Word About SHCC

SHCC is currently= booking $45,000/ month and is conservatively projecting earnings next yea= r of $1.3 million on revenues of $13 million. Unlike most e-commerc= e ventures, ShareCom's marketing "burn rate" is very modest. The= Company forecasts revenues of $32.5 million the following year, in= creasing profitability to earn $4.6 million. Given its impressive relation= ships and the rapidly growing market for its product, SHCC's share pric= e of just 1.6 cents makes it a compelling play for the astute investor.

Recently I discovered that there is a version of strace in our ports collection. I installed it and noticed that its output is a lot better. Since then I use strace exclusively for debugging and I'm very happy with it. strace follows children when you use the -f option (this is similar to ktrace's -i option).

Then it's hilarious..."? P.S. Will anybody sometime patch the jail.c to handle both IP-addresses and hostnames? -- Igor M Podlesny a.k.a.

I happened to be with IBM working on AIX (I was the AIX architecture manager at the time) during the development of the original JFS (for AIX 3.1 on the first RS/6000s). Its design and implementation were largely the result of the efforts of a single person (Al Chang) from IBM research, who was also the primary designer/developer for the VM system for AIX 3.1. Consequently, the JFS code was designed to take advantage of the specific VM implementation (and the underlying RS/6000 VM hardware). This resulted in a rather unportable code base. Additionally, since it was derived from AT&T (and BSD) filesystem code, there were some licensing issues. As I recall, these two issues (portability and license) were what lead to the reimplementation for OS/2 (I wasn't involved or even very familiar with that effort though).

I've seen other places use this, and I would commit it. :) How would this affect systems where you *have* to hit enter at the first "boot:" prompt in order to kick off a boot sequence? I've got two identical machines (same hardware, cloned hard drives), and one of them simply won't boot unless you hit enter. Turning off console imput would render this system useless after a reboot :) I think there's a PR open about this somewhere. -- Matt Emmerton To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Thu Jan 3 17:42:59 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from out006pub.verizon.net (out006pub.verizon.net [206.46.170.106]) by hub.freebsd.org (Postfix) with ESMTP id 06D1D37B416 for ; Thu, 3 Jan 2002 17:42:51 -0800 (PST) Received: from bellatlantic.net (pool-151-198-135-220.mad.east.verizon.net [151.198.135.220]) by out006pub.verizon.net with ESMTP ; id g041gU914703 Thu, 3 Jan 2002 19:42:30 -0600 (CST) Message-ID: <3C350880.ACC0E6D@bellatlantic.net> Date: Thu, 03 Jan 2002 20:42:24 -0500 From: Sergey Babkin Reply-To: babkin@freebsd.org X-Mailer: Mozilla 4.7 [en] (X11; U; FreeBSD 4.0-19990626-CURRENT i386) X-Accept-Language: en, ru MIME-Version: 1.0 To: Matthew Dillon Cc: Josef Karthauser , Alexander Haderer , freebsd-hackers@FreeBSD.ORG Subject: Re: FreeBSD performing worse than Linux?

I've stepped through the GDB code on both 4.18 and 5.1. On 5.1 I found the following in i386fbsd-nat.c: void child_resume (ptid_t ptid, int step, enum target_signal signal) { pid_t pid = ptid_get_pid (ptid); int request = PT_STEP; if (pid == -1) /* Resume all threads.

Make sure that the trace flag is off when doing a continue. There is a code path through the kernel which leaves the flag set when it should have been cleared. If a process has a signal pending (such as SIGALRM) and we do a PT_STEP, the process never really has a chance to run because the kernel needs to notify the debugger that a signal is being sent. Therefore, the process never goes through the kernel's trap() function which would normally clear it. */ eflags = read_register (PS_REGNUM); if (eflags & 0x0100) write_register (PS_REGNUM, eflags & ~0x0100); request = PT_CONTINUE; } It is pretty clear that: a) this does not deal with the case of step or next b) this does not work in the case of continue often times because step will be set to 1 and hence, this code does _not_ work around the bug. This appears to be less of a GDB bug and more of a kernel bug in ptrace. -Kip --- Donald Gillies wrote: > I think this bug may be associated only with the > SIGALRM signal.

I am also blocking all incoming icmp traffic - in fact i have explicitly denied almost all incoming traffic so i do not thing that is the problem. however if you are running ipf on the openbsd machine (which i am assuming you are) you might want to check your ruleset, it sounds like you might have something in there that is causing it.

Blocking all ICMP is bad m'kay? See also: http://www.worldgate.net/~marcs/mtu/ ipfilter with 'keep state' on the connections will automatically allow back in relevant ICMP messages such as mustfrag. The icmp messages coming up on the users console might be logged blocked packets or some such? I don't seem to recall any of the RELENG_4 systems I run spewing stuff to console if the PMTU-D was turned on. Also I wonder if the user's OpenBSD box and FreeBSD box agree on what their MTU is.

In general, that's not a good idea, IMO. It should be up to the user to decide which optimizations he wants and which not, and we do have /etc/make.conf and CFLAGS for exactly that purpose. I always hate super-clever makefiles and configure scripts that strip -O from my CFLAGS and insert -O6 -march=i686 or other unwanted things. It's a PITA. Just my 0.02 Euro.

Well, i played a bit with cvsup and found that if i wait long enough (1 or 2 timeouts of cvsup) and then try again, it works.

See now you've made me curious, and I ask myself questions like: How=20 robust is PMTU-D against someone malicious who wants to make us send=20 tinygrams? Could the connection eventually be forced down to an MTU so=20= low that no actual data transfer could occur, or TCP frames with only=20 one byte of information? Granted, the malicious person has to send back a valid set of headers=20 with their ICMP to get through ipfilter; but now I have this bad feeling=20= lurking in the back of my mind... The bad feeling is helped along by observing sys/netinet/ip_icmp.c and=20= the fact that as long as the MTU suggested is greater than 296 bytes we=20= accept the values of any ICMP mustfrag that comes in provided we have a=20= host route for it. I suppose we'll always get a couple hundred bytes in edgewise anyway,=20 but it all makes for an interesting exercise. I wonder about the=20 robustness of other operating systems to such an attack... -- Andy Carrel - william.carrel@infospace.com - +1 (425) 201-8745 Se=F1or Systems Eng. - Corporate Infrastructure Applications - InfoSpace To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Fri Jan 4 13:59:31 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from srv1.cosmo-project.de (srv1.cosmo-project.de [213.83.6.106]) by hub.freebsd.org (Postfix) with ESMTP id 129C337B405 for ; Fri, 4 Jan 2002 13:59:25 -0800 (PST) Received: (from uucp@localhost) by srv1.cosmo-project.de (8.11.6/8.11.6) with UUCP id g04LxMG66324; Fri, 4 Jan 2002 22:59:22 +0100 (CET) (envelope-from ticso@cicely8.cicely.de) Received: from mail.cicely.de (cicely20.cicely.de [10.1.1.22]) by cicely5.cicely.de (8.12.1/8.12.1) with ESMTP id g04LvFtx063064; Fri, 4 Jan 2002 22:57:15 +0100 (CET)?g (envelope-from ticso@cicely8.cicely.de) Received: from cicely8.cicely.de (cicely8.cicely.de [10.1.2.10]) by mail.cicely.de (8.11.0/8.11.0) with ESMTP id g04LvEW16286; Fri, 4 Jan 2002 22:57:15 +0100 (CET) Received: (from ticso@localhost) by cicely8.cicely.de (8.11.6/8.11.6) id g04LvDh10118; Fri, 4 Jan 2002 22:57:13 +0100 (CET) (envelope-from ticso) Date: Fri, 4 Jan 2002 22:57:13 +0100 From: Bernd Walter To: freebsd-hackers@FreeBSD.ORG, Jos Backus Subject: Re: Solaris /usr/proc/bin/pstack functionality?

Of course, now you've let the dirty little secret out of the bag: the MTU is on the *route*, which means on the next hop, so a spoof that got through would frag basically all traffic out of the victim machine down to 296 bytes... A client machine could do much worse, of course, fragging the inverse traceroute until the fragging was successful, after sending the SYN, in response to the server's "SYN-ACK"... The obvious "fix" for that is to not let the MTU be dropped if the last sent packet's size is smaller than the drop-to (can't use a "max successful" because of multiple routes and/or route assymetry). This would prevent doing it on the "SYN-ACK", or other small packet (maybe disallowing it entirely, until the first data packet has been sent). But the obvious "fix" for the obvious "fix" is to establish a connection, and then trigger the largest packet you can to be sent from the server (e.g. request a big HTTP document, which most initial pages in fact are).

I don't have the RFC handy, but aren't all Internet connected hosts required to support a minimum MTU of 576 from end to end with no fragmentation?

The way I see it is that the attack would be most common on the internet, and minuscule MTUs would most probably occur in specialistic environments. Admins of potential targets would raise the minimum to a nice value (say 512 or 1024), and print a message when something requests something below this minimum, for troubleshooting ease. Or maybe a soft limit and a hard limit. Soft limit triggers a message, hard limit is enforced. Out of curiosity, where do MTUs < ~512 occur? >The best solution is to try and make sure that the mustfrag messages are >coming from real connections we have open, and perhaps even, make sure >that the host on the remote end hasn't already ACK'ed a packet whose >header shows up in the ICMP mustfrag.

(It might just be me, mind you.) Pointers to clue would be appreciated, if it's me. First, pkg_sign doesn't seem to work at all with PGP. I get no chance to enter a passphrase, as all this stuff scrolls past: pedicular~;pkg_sign imlib2-1.0.4.tgz Short-circuiting handle_pgp_passphrase Pretty Good Privacy(tm) 2.6.3ia - Public-key encryption for the masses.

Error: Bad pass phrase. Signature error For a usage summary, type: pgp -h For more detailed help, consult the PGP User's Guide. Bus error (core dumped) pedicular~; So, I start tracing code. It seems fairly straightforward; at the point where pkg_sign should be getting a passphrase it calls handle_pgp_passphrase. ... void handle_pgp_passphrase() { pid_t pid; int fd[2]; char *p; printf("Short-circuiting %s\n", __FUNCTION__); return; /* Retrieve the pgp passphrase */ ... Now, it sure looks to me like the "return" statement on line 233 of pgp_sign.c unconditionally stops the action before you actually get the PGP passphrase, tie it to a fd so you can pass it to PGP, or anything else. Yet this is fairly new code, and I'd guess it is supposed to work... folks don't make a habit of committing b0rked code, after all. Am I just dumb, or does this really need correction?

Hmm, I'd swear there was a defined minimum, I may have the wrong one. For reference, it appears Cisco IOS based devices won't allow MTU smaller than 128 to be configured. I have no idea if that's based on some standard. It seems like there should be a minimum global standard. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - tmbg-list-request@tmbg.org, www.tmbg.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Fri Jan 4 16:52:28 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from ussenterprise.ufp.org (ussenterprise.ufp.org [208.185.30.210]) by hub.freebsd.org (Postfix) with ESMTP id AD01E37B422 for ; Fri, 4 Jan 2002 16:52:24 -0800 (PST) Received: (from bicknell@localhost) by ussenterprise.ufp.org (8.11.1/8.11.1) id g050qNS55602; Fri, 4 Jan 2002 19:52:23 -0500 (EST) (envelope-from bicknell) Date: Fri, 4 Jan 2002 19:52:23 -0500 From: Leo Bicknell To: "Rogier R.

So, it would seem the roadmap would look something like this: 1) Insure FreeBSD won't allow an MTU < 68 bytes ever. (ifconfig, icmp mtu messages, anything) 2) Implement a warning if the MTU is set smaller than some minimum value (perhaps 576 for the global internet) if admins which to see such things. 3) Allow admins to enforce a higher minimum size for servers in attack situations, knowing this violates the RFC. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - tmbg-list-request@tmbg.org, www.tmbg.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Fri Jan 4 18:42:25 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from whizzo.transsys.com (whizzo.TransSys.COM [144.202.42.10]) by hub.freebsd.org (Postfix) with ESMTP id 0B1F837CF87 for ; Fri, 4 Jan 2002 18:15:14 -0800 (PST) Received: from whizzo.transsys.com (#6@localhost.transsys.com [127.0.0.1]) by whizzo.transsys.com (8.11.6/8.11.6) with ESMTP id g052FB791341; Fri, 4 Jan 2002 21:15:11 -0500 (EST) (envelope-from louie@whizzo.transsys.com) Message-Id: <200201050215.g052FB791341@whizzo.transsys.com> X-Mailer: exmh version 2.5 07/13/2001 with nmh-1.0.4 To: Leo Bicknell Cc: William Carrel , Terry Lambert , freebsd-hackers@FreeBSD.ORG X-Image-URL: http://www.transsys.com/louie/images/louie-mail.jpg From: "Louis A.

Thus if we ever got an MTU less than 576 we should > ignore it. Right? No, all hosts are required to be able to reassemble IP datagram fragments of at least 576 bytes, but there's no lower bound on the MTU of the interface. Small MTUs first appeared on low-bandwidth SLIP links. Along with TCP header compression, this put a lower-bound on how long you'd have to wait for a single packet to be transmitted on the interface. If your network interface was clever, and looked at the TOS bits in the header or peeked at the TCP port numbers, you could arrange to queue interactive traffic (telnet, rlogin, now ssh) ahead of non-interactive traffic (FTP, SMTP, etc.) to improve the perceived response time with remote character echos. If the MTU was large, a large FTP packet might just be starting its way out the interface when you want to transmit interactive traffic; the small MTU limits the pain. (Digression: NORTEL (at least) had an interesting encapsulation on their multiservice frame relay switch trunks where they could interrupt a packet being transmitted and insert delay sensitive traffic in the middle of a larger packet. Cool hack.) Also, even though this is on a cloned route, someone could attack "well known" routes that might be on your computer. For instance, the route to well-known recursive name servers on a network, which are pretty easy to guess for dial-up users on a modem pool. louie To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Fri Jan 4 18:47: 0 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from whizzo.transsys.com (whizzo.TransSys.COM [144.202.42.10]) by hub.freebsd.org (Postfix) with ESMTP id A12F937D89D for ; Fri, 4 Jan 2002 18:31:55 -0800 (PST) Received: from whizzo.transsys.com (#6@localhost.transsys.com [127.0.0.1]) by whizzo.transsys.com (8.11.6/8.11.6) with ESMTP id g052Vt791486 for ; Fri, 4 Jan 2002 21:31:55 -0500 (EST) (envelope-from louie@whizzo.transsys.com) Message-Id: <200201050231.g052Vt791486@whizzo.transsys.com> X-Mailer: exmh version 2.5 07/13/2001 with nmh-1.0.4 X-Image-URL: http://www.transsys.com/louie/images/louie-mail.jpg To: freebsd-hackers@FreeBSD.ORG From: "Louis A.

I've got one of the litle soekris net4501 boards that I use as a router/firewall/NAT box, and it works really good. I have a stripped down FreeBSD system that I run in a 16MB partition on an 32MB Compact Flash card plugged into the net4501. Actually, I have two 16MB slices, and my goal is to be running from one, and installing the "next" version into the second slice. That way, if the new one distribution screws up, I can back-out to the older on on the other partition. That problem is that I have to generate a distribution with the right /etc/fstab to reflect which of the two slices it will be installed into, which is ugly. What would be Really Nice is a version of the "compatibility" disk devices which would be associated with the "active" slice that was booted from, rather than the first FreeBSD slice found on the disk. This seems like one mechanism to get what I want. Unfortunately, this information doesn't seem to get propagated up to the slice code from what I can tell.

One solution is to use cvsup to maintain a local copy of the cvs tree and check out source tree out using cvs. This will mean that cvs's automerging support will keep your changes untouched. You may have to resolve an occational conflict if something changes near your changes, but otherwise your changes will remain intact. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.

I don't believe you. There is no ARG_MAX limit on pipes. Probably, you are doing something whic you aren't telling us, like saying "ls *.c | wc -l" or otherwise using globbing that the shell expands to too large a list. The easy answer is "use ``find'' instead of ``ls''". -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Fri Jan 4 19:53:58 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from scaup.prod.itd.earthlink.net (scaup.mail.pas.earthlink.net [207.217.120.49]) by hub.freebsd.org (Postfix) with ESMTP id 6525C37B405 for ; Fri, 4 Jan 2002 19:53:55 -0800 (PST) Received: from pool0341.cvx40-bradley.dialup.earthlink.net ([216.244.43.86] helo=mindspring.com) by scaup.prod.itd.earthlink.net with esmtp (Exim 3.33 #1) id 16Mhu5-0003vH-00; Fri, 04 Jan 2002 19:53:53 -0800 Message-ID: <3C3678D0.49B77037@mindspring.com> Date: Fri, 04 Jan 2002 19:53:52 -0800 From: Terry Lambert X-Mailer: Mozilla 4.7 [en]C-CCK-MCD {Sony} (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: Brooks Davis Cc: David Miller , freebsd-hackers@FreeBSD.ORG Subject: Re: Overriding ARG_MAX References: <20020104190303.A21307@Odin.AC.HMC.Edu> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Brooks Davis wrote: > > I have a system where I need/want to handle lots of files in a single > > directory.

First off, you would be line counting the file contents, not the number of files. Second, the "ls" command alone will *never* hit ARG_MAX, and neither will "wc -l", if it's pipe'd to to count the number of files. He's obviously using a globbing expression he's not telling us about, and the message is from the shell expasion of the expression. Thirdly, even if it was the number of lines in the files he wanted to count, the totals will be off if xargs were to invoke "wc -l" multiple times, so the command as written can't work anyway. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Fri Jan 4 19:54:27 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from pimout5-int.prodigy.net (pimout5-ext.prodigy.net [207.115.63.98]) by hub.freebsd.org (Postfix) with ESMTP id 2F01337B41F for ; Fri, 4 Jan 2002 19:54:23 -0800 (PST) Received: from ensh (adsl-67-113-140-18.dsl.sntc01.pacbell.net [67.113.140.18]) by pimout5-int.prodigy.net (8.11.0/8.11.0) with ESMTP id g053sMe102458 for ; Fri, 4 Jan 2002 22:54:22 -0500 From: "Eric Busto" To: Subject: Phobos 4-port NIC Date: Fri, 4 Jan 2002 19:54:27 -0800 Message-ID: <000801c1959c$ac5987f0$128c7143@ensh> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit X-Priority: 3 (Normal) X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook, Build 10.0.2616 X-Mimeole: Produced By Microsoft MimeOLE V5.50.4807.1700 In-Reply-To: <006601c19592$101f38d0$e52796ca@BLUESTAR> Importance: Normal Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Howdy, I have recently acquired a pair of Phobos 4-port NIC's, the P430TX model.

I was trying to give a quick example to a general problem and I got a little too quick. What I usually want to do is something more like ls *.out |wc -l, or grep something *.data or cat *.foo | grep something. I have rebuilt the system in the past after greatly expanding ARG_MAX, and that does what I want. I'm just looking for an easy way to preserve it across cvsups, not looking for alternate ways to list the files in a directory:) > Probably, you are doing something whic you aren't telling us, > like saying "ls *.c | wc -l" or otherwise using globbing that > the shell expands to too large a list. > > The easy answer is "use ``find'' instead of ``ls''". Indeed, but it doesn't answer the basic questions, which was: Is there any easy way to override ARG_MAX (or arbitrary other paramaters) in make.conf or a config file, or something else altogether? --- David To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Fri Jan 4 20: 6:22 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from magnesium.net (toxic.magnesium.net [207.154.84.15]) by hub.freebsd.org (Postfix) with SMTP id 83B8137B41E for ; Fri, 4 Jan 2002 20:06:18 -0800 (PST) Received: (qmail 50737 invoked by uid 1001); 5 Jan 2002 04:06:18 -0000 Date: Fri, 4 Jan 2002 20:06:18 -0800 From: Bill Swingle To: Eric Busto Cc: freebsd-hackers@FreeBSD.ORG Subject: Re: Phobos 4-port NIC Message-ID: <20020105040618.GA50566@dub.net> References: <006601c19592$101f38d0$e52796ca@BLUESTAR> <000801c1959c$ac5987f0$128c7143@ensh> Mime-Version: 1.0 Content-Type: multipart/signed; micalg=pgp-sha1; protocol="application/pgp-signature"; boundary="4Ckj6UjgE2iN1+kY" Content-Disposition: inline In-Reply-To: <000801c1959c$ac5987f0$128c7143@ensh> User-Agent: Mutt/1.3.25i X-Operating-System: FreeBSD toxic.magnesium.net 4.4-STABLE FreeBSD 4.4-STABLE Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG --4Ckj6UjgE2iN1+kY Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable I had a similar (if not identical) phobos card.

I've been using AMD processors almost exclusively in my main work machines for over 4 years, and I've been very happy with them. I'm currently running a K6/233, a K6/333, an Athlon 750, a Duron 850 and an Athlon XP 1700. Last August, though, I bought a machine which gave me a lot of trouble, the Duron 850 mentioned above. I found that it would freeze for no apparent reason. I established that it wasn't the memory by taking the memory of another machine and running it like that; it made no difference. I ended up also changing the motherboard and the processor, but the hangs continued. I could expect a hang within 8 hours when doing 'make release' Just for the fun of it, I tried running Linux on it. I've been running a kernel build and 'make clean' on it now for 36 hours, and it's still running fine. Yesterday some Linux friends of mine came around and looked at it and told me that the Linux kernel I was running on the machine (2.4.16) had had a number of AMD-specific fixes put in. He didn't go into more detail, unfortunately, but I'll ask him again when I have time: it could be something relating to chipset bugs we have seen and fixed. It would help to know, though, if other people are experiencing similar problems. Please let me know if you're having problems with AMD processors which seem to be specific to FreeBSD, especially if they're hangs (i.e. the machine stops reacting, but the display still shows the last state, it doesn't reboot or panic). Information that could be interesting is (here my values): Processor: AMD Duron 850 Motherboard: ECS K7VZA Memory: 1 128 MB SIMM, 100 MHz.

I've actually been monkeying with this and ran into a bigger problem .. boot2 only knows how to handle one FreeBSD slice. You have to play loader(8) tricks to boot the second slice. Specifically... . abort the kernel load . 'set currdev=disk1s2a:' . 'load /boot/kernel/kernel' (and so forth) Particularly if you are running -CURRENT you must compile in your device hints, otherwise everything gets confused. For picking the appropriate slice, you are up a creek all right. Assumably at some point you have to select a slice anyway, and you can use that to rewrite fstab. Depending on the old compatibilty slice will certainly get you in hot water. I've been thinking about hacking up some forth to handle this switching programatically, so you get a nice menu to pick which FreeBSD slice to boot from if you enable the feature.

In a lot of cases, the capabilities have been defined but not actually implemented anywhere. sessionlimit may be one such option. I'd suggest checking login(8) since that's what generally enforces the limits (libutil just reads them).

No, there is no easy way. The limit is there in the POSIX standard, and it exists because of the need to pass data from a parent to a child over a fork + exec. The correct answer is to use "find", and either pipe or call "xargs" on the output. No matter what you do, you are going to not overcome the limit on programs that are already built (like your shell), which includded the header file and referenced the manifest constant where the limit is defined. So compatability with exiting binary apoplications already limits any change you might want to make to this. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Sat Jan 5 3:22:39 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from scaup.prod.itd.earthlink.net (scaup.mail.pas.earthlink.net [207.217.120.49]) by hub.freebsd.org (Postfix) with ESMTP id 7084537B416 for ; Sat, 5 Jan 2002 03:22:35 -0800 (PST) Received: from pool0024.cvx22-bradley.dialup.earthlink.net ([209.179.198.24] helo=mindspring.com) by scaup.prod.itd.earthlink.net with esmtp (Exim 3.33 #1) id 16MouG-0003Wp-00; Sat, 05 Jan 2002 03:22:32 -0800 Message-ID: <3C36E1F8.B64468C5@mindspring.com> Date: Sat, 05 Jan 2002 03:22:32 -0800 From: Terry Lambert X-Mailer: Mozilla 4.7 [en]C-CCK-MCD {Sony} (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: "M.

Example: When you select the 'packages' option, it will ask you about your media type. If someone doesn't have any of the media, than, they wouldn't be able to know what packages are installed on their system. (Only by doing pkg_info, but not from sysinstall.. :) What I am suggesting is, that we can make a section in the sysinstall configure menu, where we can show all the currently installed packages, and we can link up the current pkg routines such as adding, removing, so that people can easily see what packages are installed, and they can also remove them from that menu.. let me know about your views on this.. thanks, regards, - Hiten - ===== SSH Fingerprint: 1024 45:a5:9c:f2:fb:07:da:70:18:02:0b:f3:63:f1:7a:a6 hitenp@hpdi.ath.cx __________________________________________________ Do You Yahoo!?

I'm running a 4.4-STABLE based system on the hardware, and don't seem to have any problem booting off the other slice. Right now, it's runnong on the second slice of ATA Compact Flash disk: # kenv LINES="24" console="vidconsole" currdev="disk0s2a:" interpret="ok" kernel="/kernel" kernel_options="" kernelname="/kernel" loaddev="disk0s2a:" root_disk_unit="0" vfs.root.mountfrom="ufs:/dev/ad0s2a" # The other slice is ad0s1. And I checked, the kernel that's running actually did make it out of that slice, and not the first one. > For picking the appropriate slice, you are up a creek all right. > Assumably at some point you have to select a slice anyway, and you can use > that to rewrite fstab.

Where this mechanism might be useful is to detect abnormal shutdowns (too many, too quickly) and use that to backup to the other partition. I dunno, that might be more complicated and automagic than I need for the moment, since the software seems fairly stable, and the hardware is accessable for manual diddling if necessary. I'm wondering if just generating the fstab on the fly might be sufficient; I should be able to use kenv to get the vfs.root.mountfrom loader variable (which strangely enough, isn't exported as a sysctl) and go from there.

Before you say ''Bull'', please read the following. This is the letter you have been hearing about on the news lately. Due to the popularity of this letter on the Internet, a national weekly news program recently devoted an entire show to the investigation of this program described below, to see if it really can make people money. The show also investigated whether or not the program was legal. Their findings proved once and for all that there are ''absolutely NO Laws prohibiting the participation in the program and if people can follow the simple instructions, they are bound to make some mega bucks with only $25 out of pocket cost''. DUE TO THE RECENT INCREASE OF POPULARITY & RESPECT THIS PROGRAM HAS ATTAINED, IT IS CURRENTLY WORKING BETTER THAN EVER. This is what one had to say: ''Thanks to this profitable opportunity. I was approached many times before but each time I passed on it. I am so glad I finally joined just to see what one could expect in return for the minimal effort and money required. To my astonishment, I received total $ 610,470.00 in21 weeks, with money still coming in''. Pam Hedland, Fort Lee, New Jersey. ------------------------------------------------------------------------- Here is another testimonial: 'This program has been around for a long time but I never believed in it, but one day when I received this again in the mail I decided to gamble my $25 on it. I followed the simple instructions and walaa ..... 3 weeks later the money started to come in. First month I only made $240.00 but the next 2 months after that I made a total of $290,000.00. So far, in the past 8 months by re-entering the program, I have made over $710,000.00 and I am playing it again. The key to success in this program is to follow the simple steps and NOTchange anything.'' More testimonials later but first, *** PRINT THIS NOW FOR YOUR FUTURE REFERENCE *** $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ If you would like to make at least $500,000 every 4 to 5 months easily and comfortably, please read the following...THEN READ IT AGAIN and AGAIN!!! $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ FOLLOW THE SIMPLE INSTRUCTION BELOW AND YOUR FINANCIAL DREAMS WILL COME TRUE, GUARANTEED! INSTRUCTIONS: **** Order all 5 reports shown on the list below. **** For each report, send $5CASH, THE NAME & NUMBER OF THE REPORT YOU ARE ORDERING and YOUR E-MAIL ADDRESS to the person whose name appears ON THAT LIST next to the report. MAKE SURE YOUR RETURN ADDRESS IS ON YOUR ENVELOPE TOP LEFT CORNER in case of any mail problems. **** When you place your order, make sure you order each of the 5 reports. You will need all 5 reports so that you can save them on your computer and resell them. YOUR TOTAL COST $5X 5 = $25.00. **** Within a few days you will receive, vie e-mail, each of the 5 reports from these 5 different individuals. Save them on your computer so they will be accessible for you to send to the 1,000's of people who will order them from you. Also make a floppy of these reports and keep it on your desk in case something happen to your computer. ****. IMPORTANT -DO NOT alter the names of the people who are listed next to each report, or their sequence on the list, in any way other than what is instructed below in step '' 1 through 6 '' or you will loose out on majority of your profits. Once you understand the way this works, you will also see how it does not work if you change it. Remember, this method has been tested, and if you alter, it will NOT work!!! People have tried to put their friends/relatives names on all five thinking they could get all the money. But it does not work this way. Believe us, we all have tried to be greedy and then nothing happened. So Do Not try to change anything other than what is instructed. Because if you do, it will not work for you. Remember, honesty reaps the reward!!! 1.. After you have ordered all 5 reports, take this advertisement and REMOVE the name & address of the person in REPORT # 5. This person has made it through the cycle and is no doubt counting their fortune. 2.... Move the name & address in REPORT #4down TO REPORT #5. 3.... Move the name & address in REPORT #3 down TO REPORT #4. 4.... Move the name & address in REPORT #2 down TO REPORT #3. 5.... Move the name & address in REPORT #1 down TO REPORT #2 6.... Insert YOUR name & address in the REPORT #1 Position. PLEASE MAKE SURE you copy every name & address ACCURATELY! ================================================= Take this entire letter, with the modified list of names, and save it on your computer. DO NOT MAKE ANY OTHER CHANGES. Save this on a disk as well just in case if you loose any data. To assist you with marketing your business on the Internet, the 5 reports you purchase will provide you with invaluable marketing information which includes how to send bulk e-mails legally, where to find thousands of free classified ads and much more. There are 2 Primary methods to get this venture going: METHOD # 1 : BY SENDING BULK E-MAIL LEGALLY ============================================ let's say that you decide to start small, just to see how it goes, and we will assume You and those involved send out only 5,000 e-mails each. Let's also assume that the mailing receive only a 0.2% response (the response could be much better but lets just say it is only 0.2% . Also many people will send out hundreds of thousands e-mails instead of only 5,000 each). Continuing with this example, you send out only 5,000 e-mails. With a 0.2%response, that is only 10 orders for report #1. Those 10people responded by sending out 5,000 e-mail each for a total of 50,000. Out of those 50,000 e-mails only 0.2% responded with orders. That's = 100 people responded and ordered Report #2. Those 100 people mail out 5,000 e-mails each for a total of 500,000 e-mails. The 0.2% response to that is 1000 orders for Report #3. Those 1000 people send out 5,000 e-mails each for a total of 5 million e-mails sent out. The 0.2% response to that is 10,000 orders for Report #4. Those 10,000 people send out 5,000 e-mails each for a total of 50,000,000 (50 million)e-mails. The 0.2% response to that is 100,000 orders for Report # 5. THAT'S 100,000 ORDERS TIMES $5 EACH = $500,000.00 (half million). Your total income in this example is: 1..... $50+ 2..... $500+ 3..... $5,000+ 4..... $50,000+ 5..... $500,000.........Grand Total = $555,550.00 NUMBERS DO NOT LIE. GET A PENCIL & PAPER AND FIGURE OUT THE WORST POSSIBLE RESPONSES AND NO MATTER HOW YOU CALCULATE IT, YOU WILL STILL MAKE A LOT OF MONEY! ------------------------------------------------------------------------ REMEMBER FRIEND, THIS IS ASSUMING ONLY 10 PEOPLE ORDERING OUT OF 5,000 YOU MAILED TO. Dare to think for a moment what would happen if everyone, or half or even one 4thof those people mailed 100,000 e-mails each or more? There are over 150 million people on the Internet worldwide and counting. Believe me, many people will do just that, and more! METHOD #2 : BY PLACING FREE ADS ON THE INTERNET =================================================== Advertising on the net is very very inexpensive and there are hundreds of FREE places to advertise. Placing a lot of free ads on the Internet will easily get a larger response. We strongly suggest you start with Method # 1 and add METHOD #2 as you go along. for every $5 you receive, all you must do is e-mail them the Report they ordered. That's it. Always provide same day service on all orders. This will guarantee that the e-mail they send out, with your name and address on it, will be prompt because they can not advertise until they receive the report. AVAILABLE REPORTS ORDER EACH REPORT BY ITS NUMBER & NAME ONLY. Notes: Always send $5 cash (U.S. CURRENCY) for each Report. Checks NOT accepted. Make sure the cash is concealed by wrapping it in at least 2 sheets of paper. On one of those sheets of paper, Write the NUMBER & the NAME of the Report you are ordering, YOUR E-MAIL ADDRESS and your name and postal address. PLACE YOUR ORDER FOR THESE REPORTS NOW: ============================================== Report #1:"The Insider's Guide to Advertising for Free on the Net" Order Report #1 from: G Rennox Suite 284 150 Clark Blvd Brampton, Ontario Canada, L6T 4Y8 CANADA ============================================== REPORT # 2: The Insider's Guide to Sending Bulk e-mail on the Net Order Report #2 from: MS Marketing 2714 West 5th North Platte, NE 69101 USA ============================================== REPORT #3: Secret to Multilevel marketing on the net Order Report #3 from: Clairemont Richards PO Box 611437 Rosemary Beach, FL 32461 USA ============================================== REPORT #4: "How to Become a Millionaire Utilizing MLM & the Net" Order Report # 4 from: Bartolomeli Vilela Po Box 1330 Marietta, GA 30061-1330 USA ============================================== REPORT #5: "How to Send Out 0ne Million e-mails for Free" Order Report # 5 from: Marketing Resources 1812 South Hwy 77 #115-179 Lynn Haven, FL 32444 USA $$$$$$$$$ YOUR SUCCESS GUIDELINES $$$$$$$$$$$ Follow these guidelines to guarantee your success: If you do not receive at least 10 orders for Report #1 within 2 weeks, continue sending e-mails until you do. After you have received 10 orders, 2 to 3 weeks after that you should receive 100 orders or more for REPORT #2. If you did not, continue advertising or sending e-mails until you do. Once you have received 100 or more orders for Report #2, YOU CAN RELAX, because the system is already working for you , and the cash will continue to roll in! THIS IS IMPORTANT TO REMEMBER: Every time your name is moved down on the list, you are placed in front of a different report. You can KEEP Track of your PROGRESS by watching which report people are ordering from you. IF YOU WANT TO GENERATE MORE INCOME SEND ANOTHER BATCH OF E-MAIL SAND START THE WHOLE PROCESS AGAIN. There is NO LIMIT to the income you can generate from this business!!! ____________________________________________________ FOLLOWING IS A NOTE FROM THE ORIGINATOR OF THIS PROGRAM: "You have just received information that can give you financial freedom for the rest of your life, with NO RISK and JUST A LITTLE BIT OF EFFORT. You can make more money in the next few weeks and months than you have ever imagined. Follow the program EXACTLY AS INSTRUCTED. Do Not change it in any way. It works exceedingly well as it is now. Remember to e-mail a copy of this exciting report after you have put your name and address in Report #1 and moved others to #2...........#5 as instructed above. One of the people you send this to may send out 100,000 or more e-mails and your name will be on everyone of them. Remember though, the more you send out the more potential customers you will reach. So my friend, I have given you the ideas, information, materials and opportunity to become financially independent. IT IS UP TO YOU NOW! ************** MORETESTIMONIALS**************** ' My name is Mitchell. My wife, Jody and I live in Chicago. I am an accountant with a major U.S. Corporation and I make pretty good money. When I received this program I grumbled to Jody about receiving ''junk mail''. I made fun of the whole thing, spouting my knowledge of the population and percentages involved. I ''knew'' it wouldn't work. Jody totally ignored my supposed intelligence and few days later she jumped in with both feet. I made merciless fun of her, and was ready to lay the old ''I told you so'' on her when the thing didn't work. Well, the laugh was on me! Within 3 weeks she had received 50 responses. Within the next 45 days she had received a total of $ 147,200.00 all cash!I was shocked. I have joined Jody in her ''hobby''. Mitchell Wolf, M.D. , Chicago, Illinois ------------------------------------------------------------------------- Not being the gambling type, it took me several weeks to make up my mind to participate in this plan. But conservative that I am, I decided that the initial investment was so little that there was just no way that I wouldn't get enough orders to at least get my money back. I was surprised when I found my medium size post office box crammed with orders. I made $319,210.00 in the first 12 weeks. The nice thing about this deal is that it does not matter where people live. There simply isn't a better investment with a faster return and so big''. Dan Sondstrom, Alberta, Canada ------------------------------------------------------------------------- 'I had received this program before. I deleted it, but later I wondered if I should have given it a try. Of course, I had no idea who to contact to get another copy, so I had to wait until I was e- mailed again by someone else.........11 months passed then it luckily came again...... I did not delete this one! I made more than $490,000 on my first try and all the money came within 22 weeks''. Susan De Suza, New York, N.Y. ----------------------------------------------------------------------- '' It really is a great opportunity to make relatively easy money with little cost to you. I followed the simple instructions and within 10 days the money started to come in. My first month I made $ 20, 560.00 and by the end of third month my total cash count was $ 362,840.00. Life is beautiful, Thanx to Internet''.

I measure SLIP's effeciency (in throughput) to be about 5-15% more effecient than PPP in older versions of FreeBSD (both using kernel versions, slip and ppp). Since both were using static configurations on both ends and the only traffic was TCP/IP, there was no reason to use PPP over SLIP so we opted for using the more effecient protocol. I can imagine this is SLIP is still more effecient than PPP in terms of CPU, although I haven't measured it in years.

The only think that can get around it is an overly anal hop count comparison (which could fail, if there were multiple equivalent routes), or turning off the ICMP (which is what started this thread in the first place). -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Sat Jan 5 13: 2: 5 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from servidor1.cursosvirtuales.com.ar (www.cursosvirtuales.com.ar [200.10.104.198]) by hub.freebsd.org (Postfix) with ESMTP id 0325137B41B for ; Sat, 5 Jan 2002 13:02:01 -0800 (PST) Received: (from fpscha@localhost) by servidor1.cursosvirtuales.com.ar (8.11.1/8.11.1) id g05L2iW67469 for freebsd-hackers@freebsd.org; Sat, 5 Jan 2002 18:02:44 -0300 (ART) (envelope-from fpscha) From: "Fernando P.

One of the often missed things is the use of /dev/null on grep in this case. If you grep a single file ("grep string file") then it prints the matches. If you grep multiple files ("grep string file1 file2") it prints the matches with the file name prepended. When using xargs, if the number of things to search results in just one being left for the last call to grep you will get all of your results prepended with the file name, except for the last file which will be just the results. Adding /dev/null insures grep always has 2 or more files. Another fix would be: find -name "*.data" -maxdepth 0 | xargs grep -H something I don't believe old grep's had -H though, which is where the /dev/null trick came from. In any event, using find is much better, not so much for this example, but because it allows you to do things like check permissions in a portable way: find -name "*.data" -perm 444 | xargs grep -H something You can't do that with ls | grep, since only the filenames make it to grep. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - tmbg-list-request@tmbg.org, www.tmbg.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Sat Jan 5 13:17:30 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from elvis.mu.org (elvis.mu.org [216.33.66.196]) by hub.freebsd.org (Postfix) with ESMTP id 9588637B41A; Sat, 5 Jan 2002 13:17:05 -0800 (PST) Received: by elvis.mu.org (Postfix, from userid 1192) id 3BF2F81D01; Sat, 5 Jan 2002 15:17:05 -0600 (CST) Date: Sat, 5 Jan 2002 15:17:05 -0600 From: Alfred Perlstein To: alc@freebsd.org Cc: tegge@freebsd.org, hackers@freebsd.org Subject: oddness in aio_procrundown?

Depending on Linux's behaviour, which is contrary to conformance to the POSIX standard, will make your code non-portable. > Is this a known behavior? Yes. Even better, it's standard. > Is there any way to change it? When you get the first SIGIO, set a flag (volatile) in the signal handler. In your main loop, check for the flag, and if it is present, use poll/select to verify that there is data pending, and while there is data pending, retrieve it. At most, you will recheck one extra time for a run of N events (N+1 times), and since you are concerned about N >= 23, this overhead is practically non-existant. If you want to avoid the "extra" system call, then switch to using non-blocking I/O, and when the number of bytes processed by the call is 0, then you are done with that iteration. This approach is portable between all versions of UNIX that support select or poll (you can conditionally compile the code based on the presence or absences of FD_SET_SIZE, or other manifest constants associated solely with the poll or select system calls, so the resulting code will be 100% portable source code). See also the source for the "init" program, which has to be able to reap child processes, and so has to do SIGCHLD or SIGCLD (depending on your flavor of UNIX) handling the same way. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Sat Jan 5 14:25:27 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from lurza.secnetix.de (lurza.secnetix.de [212.66.1.130]) by hub.freebsd.org (Postfix) with ESMTP id A6D4037B427 for ; Sat, 5 Jan 2002 14:25:10 -0800 (PST) Received: (from olli@localhost) by lurza.secnetix.de (8.11.6/8.11.6) id g05MPHf59931; Sat, 5 Jan 2002 23:25:17 +0100 (CET) (envelope-from oliver.fromme@secnetix.de) Date: Sat, 5 Jan 2002 23:25:17 +0100 (CET) Message-Id: <200201052225.g05MPHf59931@lurza.secnetix.de> From: Oliver Fromme To: freebsd-hackers@FreeBSD.ORG Reply-To: freebsd-hackers@FreeBSD.ORG Subject: Re: Overriding ARG_MAX In-Reply-To: <20020105211124.GA76316@ussenterprise.ufp.org> X-Newsgroups: list.freebsd-hackers User-Agent: tin/1.5.4-20000523 ("1959") (UNIX) (FreeBSD/4.4-RELEASE (i386)) MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 8bit Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Leo Bicknell wrote: > In a message written on Sat, Jan 05, 2002 at 09:48:40PM +0100, Oliver Fromme wro > te: > > ls | grep '\.out$' | wc -l > > One process shorter: find -name "*.out" -maxdepth 0 | wc -l OK, but I tried to be as portable as possible, while -maxdepth is not portable (e.g. Solaris doesn't have it). > > ls | grep '\.data$' | xargs grep something > > Two problems, first use find, second use /dev/null: > find -name "*.data" -maxdepth 0 | xargs grep something /dev/null But that one will give you different result than the original command.

Sorry, I wasn't clear. I don't have any explicit configuration in my loader.conf; this is just the environment that the loader cooked up all by itself.

What you might try is making sure that the other partition starts on a cylinder boundary. I've noticed that the BIOS on some machines have real heartburn when the slice starts at some random location not coincident with a cylinder boundary. I don't know why, and I'm pretty sure I don't want to know :=) louie To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Sat Jan 5 15:43:17 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from imo-m08.mx.aol.com (imo-m08.mx.aol.com [64.12.136.163]) by hub.freebsd.org (Postfix) with ESMTP id BEEEB37B416 for ; Sat, 5 Jan 2002 15:43:12 -0800 (PST) Received: from TD790@aol.com by imo-m08.mx.aol.com (mail_out_v31_r1.9.) id j.4f.1688d60a (1321); Sat, 5 Jan 2002 18:43:06 -0500 (EST) From: TD790@aol.com Message-ID: <4f.1688d60a.2968e98a@aol.com> Date: Sat, 5 Jan 2002 18:43:06 EST Subject: Re: Phobos 4-port NIC To: busto@sbcglobal.net Cc: hackers@freebsd.org MIME-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit X-Mailer: AOL 5.0 for Windows sub 139 Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG In a message dated 01/04/2002 10:54:51 PM Eastern Standard Time, busto@sbcglobal.net writes: > I have recently acquired a pair of Phobos 4-port NIC's, the P430TX > model.

Phobos always claimed "superiority", but its just a PCI bridge and (the same old) 21143 as all of the other 4 port cards (yawn)...if it doesnt work with the dc driver then I'd dump it.

Or if there is are plausible ways to attack that don't require someone to sniff and inject into a connection in which the victim is participating (if you can do that, you can do much worse). The typical SYN flood or DDOS are real threats. This thread (and the previous ones like the one Darren started a few months back) have already expended more energy on the issue than the threat warrants. -- "It's always funny until someone gets hurt.
