Hi! Just have the same problem in our students-home network... Peer-to-peer network, every OS present, of course no central administration... ;-( 150 users conected... OK: How do you perform a search for cards in promiscuous mode? (Taking some expensive analyzer progs or some simple stuff under UN*X, Linsux or NT?) 2nd: are there any possibilities to think of, that a card is set to promiscous mode, with no TCP-IP stack behind it to handle requests the normal way, but a "special" stack written to behave like this: Packets are sniffed/come in, as the card sees every packet on the wire/segment. some software written especially for this determines if some criteria match a defined pattern (like a range of IP or MAC numbers, from some other known machines on that network) if a packet from/or for such a machine arrives, some action is taken, like dumping that segment to HDD or sending some counter-measures, like a POD attack or so... That way you also could easily sniff out mail passworts, as they are not encrypted. What would one need (time and programming skills) to do such a beast? I'm very curious to that, since we already had a bad sniffer attack from inside, where some mail passwords were hacked. And as our university, where we are connected to with the entire students living block, does not care about that security, we have to figure out about security alone...

Since the switch needs to operate so quickly, is it probable that such a switching table is actually in silicon or programmed into an FPGA? That would make sense of why the table would be so small; it reminds me of the limited way multicast addresses are handled by a typical NIC. --------------------------------------------------------------------- Dan Davis | Excerpt from my latest project: Software Engineer | 0000100010111000001010010001 ECCS, Inc. | 1000101011110110001110101000 dand@eclipse.net | "That's the philosophical equivalent of http://www.eccs.com | Folger's crystals!" - Dan --------------------------------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Tue Jan 4 11:12:20 2000 Delivered-To: freebsd-net@freebsd.org Received: from mout1.01019freenet.de (mout1.01019freenet.de [62.104.201.3]) by hub.freebsd.org (Postfix) with ESMTP id BCE6F14E63 for ; Tue, 4 Jan 2000 11:11:38 -0800 (PST) (envelope-from julian@elischer.org) Received: from [62.104.201.6] (helo=mx0.01019freenet.de) by mout1.01019freenet.de with esmtp (Exim 3.12 #2) id 125ZMa-0005ue-00; Tue, 04 Jan 2000 20:11:24 +0100 Received: from [212.81.154.214] (helo=jules.elischer.org) by mx0.01019freenet.de with smtp (Exim 3.12 #2) id 125ZMa-0002gf-00; Tue, 04 Jan 2000 20:11:24 +0100 Message-ID: <387242B9.3F54BC7E@elischer.org> Date: Tue, 04 Jan 2000 11:11:11 -0800 From: Julian Elischer X-Mailer: Mozilla 3.04Gold (X11; I; FreeBSD 4.0-CURRENT i386) MIME-Version: 1.0 To: Wes Peters Cc: DRHAGER@de.ibm.com, Olaf Hoyer , freebsd-net@FreeBSD.ORG Subject: Re: sniffing networks References: <38721113.FBC3B90E@softweyr.com> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Wes Peters wrote: > > DRHAGER@de.ibm.com wrote: > > > > OK: How do you perform a search for cards in promiscuous mode? > > (Taking some expensive analyzer progs or some simple stuff under UN*X, > > Linsux or NT?) > > Why would you want to search for network interfaces in promiscuous mode? > Stick the users on switched ports so they can't sniff other users packets > and be done with it the way to do this is to send ping packets to each IP address but with the wrong MAC address.

The NetGear FS-105 uses a 1K hash on the destination MAC address; this is typical for layer-2 switches. -- "Where am I, and what am I doing in this handbasket?"

Was hoping maybe julian, archie, brian, another PPPoE guru may be able to help me out.. :) Dear Fellow Freebsd question readers, I would like to open up this plea for help first by thanking brian somers, archie cobb, and julian elischer for some excellent code, i.e. Netgraph and user-PPP. This code definately worked real well. I had the netgraph and user-ppp running great together until I cvsup'd one day and did a make world. I went to bed, woke up, and there was no connection. So I started looking through my logs to see if I could find out what happened. Here is what my normal connection looks like - this is using Netgraph from a recent cvsup on a 3.4-STABLE build with user-ppp 2.24. After all my trouble occured I went to Brian's web page and grabbed his 2.26 user-ppp and compiled it and still had the same results. Here is a log of what usually happens when it connects properly, and I'll also paste my ppp.conf and options file, etc. after a log of a good connection and then what happens when I try to connect after the cvsup. I intiate the command ./ppp -nat -ddial default to connect and it always worked fine, I tried it without the nat flags of course to.

This could mean that my connection is just down and something is messed on bellsouth's end, or possibly that Netgraph isn't getting the call from ppp, or netgraph just isn't recieving NGM_PPPOE_SUCCESS from my bellsouth server. I'm not actually quite sure how it works. I Have compiled the netgraph code into the kernel with the options NETGRAPH, options NETGRAPH_PPPOE, and options NETGRAPH_SOCKET. Like I stated, I'm not quite sure how this NGM_PPPOE_SUCCESS hook works.. if it is recieved from bellsouth and their server, or recieved from ppp and it is ppp that isn't calling it. If user-ppp is the problem in why it isn't grabbing that NGM_PPPOE_SUCCESS, how can I fix this? I see that there is a -DNONETGRAPH command in user-ppp that could be the cause of this, but I'm not quite sure of the legistics. I also went and grabbed the new user-ppp sources from brian's page and compiled them and tried the same thing with the new user-ppp 2.26 and had the same results, just it trying to reconnect over and over again getting that same log as posted above. Here are my ppp.conf and options files: /etc/ppp/options default: set device PPPoE:mx0 set mru 1492 set mtu 1492 deny pap accept chap set speed sync set cd 5 set authname XXXX@bellsouth.net set authkey xxxxxx enable lqr set redial 0 0 set dial add 0 0 HISADDR ppp.conf looks the same way too, not sure if that was correct or not, but it was working for quite sometime greatly.. :) I also had underneath all the options in default an, interactive: section that has the same information listed as under the default heading. Anyways, if anybody could help me out and figure out why this stopped connecting it would be greatly appreciated. It may be bellsouth's side, and it may be something that I compiled wrong on my side after the cvsup by doing the make world, that I am not sure of. I am hoping that some of these logs will let someone get an idea of what is going on so they can possibly help me on my way to a resolution. It may be something as simple as editing out the -DNONETGRAPH lines in the Makefile in /usr/src/usr.sbin/ppp - but I'm not sure what I did the first time around to make it function correctly. Once again, thanks everybody for listening and coming together to get this code together. Archie, Brian, Julian, everyone else, excellent work and thanks from a freebsd user that can use a PPPoE connection.

Weird network/routing question. Reply-To: ji@research.att.com Organization: AT&T Labs - Research Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Here is the setup: Hosts alice and bob, running 3.4-STABLE, xl interfaces. on alice: # ifconfig xl1 10.1.1.1 up netmask 255.255.255.255 # netstat -r -n ... 10.1.1.1/32 link#2 UC 0 0 xl1 ... # ping 10.1.1.1 (yes, it pings fine) # netstat -r -n ... 10.1.1.1 0:10:4b:63:80:33 UHLW 0 4 lo0 => 10.1.1.1/32 link#2 UC 0 0 xl1 ... So far, everything is fine. Do the same on bob; # ifconfig xl1 10.1.1.2 up netmask 255.255.255.255 bob can also ping himself. Now, how to ping bob from alice? The obvious thing would be to say # route add -interface 10.1.1.2 10.1.1.1 which creates the following routing entry: 10.1.1.2 10.1.1.1 UHS 0 60 xl1 which of course doesn't work. So, what's the right way to do this? (No, I can't have a shorter subnet mask and put both interfaces on the same subnet! Needless to say, what I've described is the simplified problem). There has to be a way to tell the routing code "this address may not look like it's on any of your subnets, but the way to reach it is to ARP for it through interface xl1". There was definitely a way of doing this back in the SunOS 4 (and before) days.

You could try publishing an arp entry for 10.1.1.2 on 10.1.1.1 (and vice versa on 10.1.1.1) using the MAC addresses physically associated with the respective IPs of course. The boxen may consider the arp entries of no consequence being that neither considers the other host to be on an attached subnet. As an alternative you could place the IPs on the loopback interfaces as aliases using the ethernet addresses as gateways to these IPs. - Barrett To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Fri Jan 7 8:25: 2 2000 Delivered-To: freebsd-net@freebsd.org Received: from fledge.watson.org (fledge.watson.org [204.156.12.50]) by hub.freebsd.org (Postfix) with ESMTP id CAB6B1575C for ; Fri, 7 Jan 2000 08:24:59 -0800 (PST) (envelope-from robert@cyrus.watson.org) Received: from fledge.watson.org (robert@fledge.pr.watson.org [192.0.2.3]) by fledge.watson.org (8.9.3/8.9.3) with SMTP id LAA39042; Fri, 7 Jan 2000 11:24:27 -0500 (EST) (envelope-from robert@cyrus.watson.org) Date: Fri, 7 Jan 2000 11:24:27 -0500 (EST) From: Robert Watson X-Sender: robert@fledge.watson.org Reply-To: Robert Watson To: Mitch Collinsworth Cc: Wes Peters , DRHAGER@de.ibm.com, Olaf Hoyer , freebsd-net@FreeBSD.ORG Subject: Re: sniffing networks In-Reply-To: <200001041729.MAA16004@benge.graphics.cornell.edu> Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org On Tue, 4 Jan 2000, Mitch Collinsworth wrote: > >Stick the users on switched ports so they can't sniff other users packets > >and be done with it. > > According to a friend who has done some network monitoring tests this > is not as perfect a solution as it sounds.

You should not rely on switches for security unless your switch allows you to hard-assign MAC addresses to ports on the switch, and you hard assign IP addresses to these MAC addresses on the end hosts. MAC addresses can be spoofed, so race conditions can exist where you receive data for others, as well as other issues; similarly, ARP and ICMP redirect both occur above the switch level--switching protects messages based on destination MAC address, not destination IP address. The best thing to do is use real crypto, which means you no longer care about who sees the packets. There are still issues with leaked electromagnetic spectrum, but the chances are you aren't interested in those attacks :-).

When a route drops and I try to do a 'route get' on that subnet... in stead of discovering the route it gives me the following... route: writing to routing socket: No such process routed is clear a process running on the router. After the route get fails I try and set the route nonstatic route add 192.168.1.0/24 10.10.10.1 -nostatic those of course are not the real numbers but that is the standard command... moments after my added route appears in the route table it disappears again... so I am forced to defeat the purpose of rip and add the route in static... I was emailed a suggestion about the default route and whether I had it set... the default route is unwaivering during this strangeness. I was emailed a suggestion about netstat...

Try to set up static routing and see if it works. -- << Marcin Cieslak // saper@system.pl >> ----------------------------------------------------------------- SYSTEM Internet Provider http://www.system.pl To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Fri Jan 7 16:29:18 2000 Delivered-To: freebsd-net@freebsd.org Received: from cs.rice.edu (cs.rice.edu [128.42.1.30]) by hub.freebsd.org (Postfix) with ESMTP id 6828715008 for ; Fri, 7 Jan 2000 16:29:15 -0800 (PST) (envelope-from aron@cs.rice.edu) Received: (from aron@localhost) by cs.rice.edu (8.9.0/8.9.0) id SAA05791 for freebsd-net@freebsd.org; Fri, 7 Jan 2000 18:29:13 -0600 (CST) Date: Fri, 7 Jan 2000 18:29:13 -0600 (CST) From: Mohit Aron Message-Id: <200001080029.SAA05791@cs.rice.edu> To: freebsd-net@freebsd.org Subject: performance of FreeBSD-current as SMP Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Hi, I did some simple throughput tests on a handcoded fast webserver when FreeBSD-current (snapshot from 3rd January) is/is not configured as an SMP.

If your processing mix is able to take advantage of concurrent processing, then you will see a net performance boost, but not the expected doubling (due to the overhead penalty). The question is, does your benchmark allow concurrent processing? If you have a single Network Interface Card, does it act as a non-sharable resource that effectively precludes concurrent processing by two web server processes? Your web server does spawn a new process for each client session, and you are generating multiple client sessions concurrently, right? orville.

I really need to understand this. I have several FreeBSD machines which live behind a coporate firewall. Untill recently access to http browsing was on "need only" basis. It was throught a SOCKS firewall that did some sort of authentication. Now it has been opened up to "everyon", except the MIS types on "support' microsloth machines :-( After having looked at one of thes machines, I see that Nescape on the is configured to use "automatic proxyin" and this proxy is pointed to a file on a Novell fileserver. Here are the contents of this file: function FindProxyForURL(url, host) { if (isInNet(host, "170.85.18.11", "255.255.255.128")) return "SOCKS 170.85.17.10:1080; DIRECT"; else if (isInNet(host, "170.85.0.0", "255.255.0.0")) return "DIRECT"; else return "SOCKS 170.85.17.10:1080; DIRECT"; } Now, what this does is pretty obvious, if the reference is outside our corporate net (170.85.*) it calls a SOCKS proxy, otherwise, it goes direct. I need to be able to replicate this behavior for the UNIX machines behind the firewall. I have a internal FreeBSD machine that runs Apache, that I think I can do this with, but just putting this file on it, and pointing my UNIX clients to it results in nescape error, referencing a MIME type error. Can someone please educate me on how to make this work? Thanks -- Stan Brown stanb@netcom.com 404-996-6955 Factory Automation Systems Atlanta Ga. -- Look, look, see Windows 95. Buy, lemmings, buy!

(everything is mostly backward compatible, you only need to recompile ipfw if you want to use the new dummynet features, but the syntax remains the same). They are listed below: REWRITTEN MANPAGE, trying to make it more readable. Please let me know if i succeeded or not. DUMMYNET now supports dynamically-created per-flow queues. E.g. if you want to limit each /24 subnet to your web server to 100Kbit/s you can do now: ifpw add pipe 1 tcp from my-ip 80 to any ipfw pipe 1 config bw 100Kbit/s mask dst-ip 0xffffff00 and so on. The manpage gives more examples. User interface is fully backward compatible. This work sponsored by Akamba Corp. As a side effect, the new dummynet code also fixes one bug in the previous code which could cause large bursts of packets. DUMMYNET should also work on the alpha, because i have fixed the interface problems which prevented this on the past. IPFW now supports masks on TCP/UDP ports, which can be useful for some simulation purposes and does not impact performance. Feedback appreciated. If there are no objections, i would like to put these things into -stable soon, as there are important fixes to existing features. cheers luigi -----------------------------------+------------------------------------- Luigi RIZZO, luigi@iet.unipi.it .

According to Garret's earlier posting, there seem to be some very expensive Intel instructions being used for locking.

Are you referring to a NAT or IP Masquerading "gateway"? I can't imagine how IP aliasing would interfere with QuickTime streaming. There was a discussion on the MkLinux-setup list (@public.lists.apple.com); you might check there (I've forgotten the details, but there is a "firewall" setup that allows QuickTime streams through).

Yes, I thought that the streaming should've worked since we can get streaming Realmedia, but for some reason, I am thinking, (and this is beyond my knowledge base), that I read that the implementation of true RTP/RTSP and an IP aliasing system are inherently incompatible (I figured that RealNetworks did their own thing). Whether that's correct or not, if we try to connect to a quicktime stream, the player will always appear to time out (it returns an error code, for which we have no lists of explanations.) However, when we dial in directly to the ISP with the client machine, that is, without any gateway box, it works fine. I will check out the references here and see if I can come up with an answer.

Yup. During the RTSP "negotiations" the client and server exchange address/port pairs for RTP. So your masquerading box needs to go in to the RTSP payloads and change the IP addresses and ports there, then set up the necessary (udp) port forwarding. You could also use a proxy. I think realmedia uses something akin to ftp passive mode (streaming data sent across the initial tcp connection) - rtsp/rtp supports this, but that does not mean that the servers or the clients do. dave To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Sat Jan 8 21:22:51 2000 Delivered-To: freebsd-net@freebsd.org Received: by hub.freebsd.org (Postfix, from userid 758) id C760D14A31; Sat, 8 Jan 2000 21:22:49 -0800 (PST) Received: from localhost (localhost [127.0.0.1]) by hub.freebsd.org (Postfix) with ESMTP id B6DF41CD82B; Sat, 8 Jan 2000 21:22:49 -0800 (PST) (envelope-from kris@hub.freebsd.org) Date: Sat, 8 Jan 2000 21:22:49 -0800 (PST) From: Kris Kennaway To: Boozy Cc: freebsd-current@FreeBSD.org, freebsd-net@FreeBSD.org Subject: Re: -current or 3.4 with KAME ???
