I have a Nortel RT-338 stand-alone ISDN router that uses DHCP. I set
the pool size to 2 & the starting IP of the pool to 192.168.0.2. The
router has an internal IP of 192.168.0.1. This allows me to use a
crossover cable to hook the router into nic #1 on the fbsd box, which
has the 192.168.0.2 IP. The second nic in the fbsd box has an IP of
192.168.150.150, and it is hooked into a hub, where W2k boxes w/ IP's
of 192.168.150.154 & 192.168.150.156 are also hooked. The dfgw on the
W2k boxes are set to 192.168.150.150, and the DNS addresses are set to
192.168.0.1. I used route add to enable the W2k boxes to access the
192.168.0.0 from the 192.168.150.150 interface. I used "route add -net
0.0.0.0 192.168.0.1" on the fbsd box to allow outside contacts. I have
the following set in /etc/resolv.conf...
nameserver 192.168.0.1
nameserver <the ip address of my ISP's primary DNS server>
nameserver <the ip address of my ISP's secondary DNS server>
I do not have   named_enable="YES" in /etc/rc.conf
I can ping the 192.168.0.2 from the W2k boxes, and a ping to
192.168.0.1 triggers the router to activate the ISDN line. However,
when the line hooks, i cannot ping outside IP's from the W2k boxes.
I can ping an outside IP from the fbsd box, however. A web browser 
on the W2k boxes will trigger the ISDN, also, but no data gets through.
IPFW is default to accept, and I have tried ppp_nat="YES" in rc.conf
to no avail. I do not have firewall enabled in rc.conf, I will use it
when
I get IPFW rules set up accordingly.
I have   static_routes="" in rc.conf...should this be static_routes=" "
?
This is on a 4.0 release box, and the syntax from 3.2 fails, where it
allowed static_routes="route_blahone route_blahtwo"
        route_blahone="-net xxx.xxx.xxx.x xxx.xxx.xxx.xxx"
        route_blahtwo="-net xxx.xxx.xxx.x xxx.xxx.xxx.xxx"
I am not running any routing daemons, like routed or mrouted, and
gateway_enable="YES" in rc.conf, and default_router="192.168.0.1"
I also have forward_sourceroute & accept_sourceroute set to yes.

Can I get this working just using the routing tables? If so, what route
add
am I missing? I do not understand the man page for "route" that well,
especially the  -interface  option.
                                         Thanks,
                                                Jeb

Interesting point. Unfortunately, since the server isn't going to echo
back the chars, DON'T ECHO has the same effect.

The difference between DON'T/WILL has effect if you assume, that the
server echo's back each char it receives. Then client in WILL
situation will echo, client in DON'T won't echo. But since the server
won't echo anyways, there's no difference.

You could have pointed that out without telling us we are wrong, which
isn't true.

Have you actually tried it, with a real telnet client?

As I understood the question, it was:  How does the server make the
client stop echoing to the user?  And the answer is for the server
to tell the client that it will do the echoing itself, and then
not really do it.

See RFC 857.

I did, months ago the last time and yesterday again, because I was unsure.
DONT ECHO is correct in this case, also, to turn off local echo.

Ok sure you can make up a domain name...but remember if you ever connect to the net
then you MAY have to reconfigure every workstation on that lan...unless you do
something slick like put to ethernet cards in anf set up a gateway with
ipfw/natd...then you could have a cluster of workstations on the the inside private
lan...we shall call ws1.clstr, ws2.clstr, ???.clstr for instance...and the one
workstation that is actually connected to the world has a real domain name....On
the flip side if you neve connect to the net thenit doesn't really matter....name
them all .slug if you like...just remember to add an entry for each one in
/etc/hosts on each machine...

Hello

The network software is commonly layered into hierarchy of protocols,
for example the TCP/IP implementation.

The FreeBSD kernel support a late binding between layers?  How ?

Thanks.

Sigh.  Quoting RFC 857:

   IAC DON'T ECHO

      The sender of this command DEMANDS the receiver of this command
      stop, or not start, echoing data characters it receives over the
      TELNET connection.

In other words, having the server send the client IAC DONT ECHO tells
the client not to echo, back to the server, characters it receives
from the sender.  But, of course, the client is already in that state.

Don't be too sure.  Reflections can cause *really* strange problems.
I've had machines close to each other (i.e. seperated by a 6' piece of
10b2) been unable to talk to each other while they could both talk to
a machine 100' away.

Thus spake Barney Wolff (barney@databus.com):

> Sigh.  Quoting RFC 857:

Either you are right and all telnet-clients I can use atm (Linux,
Windows9x, FreeBSD) have implemented things wrong or maybe you are
wrong.
If you are right, I suggest you rewrite things and shout at the guys
that they have implemented the protocol wrongly and send them patches.
In this case, I was also right, since I said the things have the same
effect (on clients _I_ know, also, if this violates the RfC).

I suggest trying out the attached source, with and without commented
out the handshake and see, what happens.

In your opinion this should have no effect since DONT ECHO doesn't
mean that.

Thanks

Man, I suck. You are right, of course.
I always meant WILL all over the time. I was just too dumb to read
numbers (I read my source and thought 373o == 254d, argl).

Sorry.

I would check on the distance between the units; I've seen
instances where systems were too close or pessimistically
phased and couldn't hear each other.

	I'm sorry, as this is probably already the second time I'm asking you
  to do this (I unfortunately lost the first copy), but can you send me the
  code that you're using to simulate the exhaustion? (no need to CC is to
  the list, send directly to me). With that, I'll be able to get data and
  values that I can also try analyzing (now that this semester is officially

	What you'd need in this case is also to get some information from the
  tcpcb in question.

They've hung around 2 days so far on this boot.  I haven't had very long
uptimes in the last few weeks due to playing around with the patches, but
since they last longer than 5 minutes, I'm guessing they'd hang around
virtually forever.

I think Barney is correct.  When I wrote my first telnet server
in 1982, telnet worked that way, and it still works this way.  Telnet
option negotiation has been well understood for decades now.

My personal experience with this was on a big, horrible mainframe computer
which presumed half-duplex printing terminals and which didn't echo
what you typed.  (This is actually the default state when a telnet 
sessions begins; UNIX telnet servers negotiate WILL ECHO so that the
local client doesn't echo what you type.)  So, in my case, when the
OS told me it was prompting for a password though a mechanism I won't 
describe to you here in case you're eating, my telnet server would
claim to peform remote echoing, and then wouldn't during the duration
of the password prompt. It then negotiated WONT ECHO with the telnet
client, so that the local echoing resumed.

Note that to really get this right, when the telnet server sends a
WILL ECHO, you should wait for the client to respond with DO ECHO
before sending the prompt to ensure that the client's local echo was
been disabled.

While you can probably get away with just jamming the various telnet
control sequences into the TCP connection (e.g., IAC WILL ECHO), there
really is a state machine on both sides, as well as byte-stuffing of the
IAC (binary value 0xff) going on too.

I have gone back to the ppp manpage and read the "ppp command" section
(line 1711) and tried the following commands from ppp:

PPP ON fbsd> nat enable yes
PPP ON fbsd> nat port tcp 192.168.0.2:80 80

Still doesn't work though, visitors keep getting the www server on host
fbsd instead of being redirected to fbsd2 (even after hitting reload, in
case the page was cached). Note that I only want www services redirected,
so I don't think I can use the "nat addr" command. Considering my network
setup is rather simple and I've recently cvsup'ed to stable, I really
don't see what could be wrong. Any other ideas would be most welcome.

Strange, I've got 

 nat enable yes
 nat port tcp dev:http http
 nat port tcp dev:ident ident
 nat port tcp gate:22 2201
 nat port tcp dev:22 2205
 nat port tcp rivet:22 2206
 nat port tcp hak:22 2212
 nat target default

in my config and everything works as expected.  The only thing I can 
suggest you do is try ``nat log yes'' and see if anything interesting 
turns up in /var/log/alias.log.

Hi,


Ever since installing sshd (which works just fine) my ftpd gives the
following error message:

ftpd[proces-ID] "getpeername (/usr/libexec/ftpd): socket operation on
non-socket"

Any help ?

Thanks,
Aernoudt

  would any kind soul care to share w/ me how to send data out a particular 
nic. I'm doing socket programming and I'm not able to send
outbound packets via the interface that I want. Can one use the 'bind' 
function to set the outbound nic (somehow)? should I be using raw sockets? I 
am hoping that I can do this w/o using libpcap ... which is where I'm headed 
next.

any urls, points, suggestions would be helpful
tks,
manny

Each NIC has a unique IP address, right?  You can bind to that address.

Yes. Take a look at the daemon I had. You don't bind to INADDR_ANY but
to the IP (that is, also for outgoing).

You should buy a TCP/IP-programming book such as Stevens' "Unix
Network Programming". It's very good.

Manny,

There are a number of good books on the topic of network programming. 
I recommend "UNIX Network Programming, Volume 1, 2nd Edition" by
W. Richard Stevens (ISBN: 013490012X).  If you are going to be doing
network programming in a Unix development envoronment, this book is
extremely useful.

	I have a FreebSD 3.4 machine that I use for a NAT, ipfw firweall from
	my cablemodem provider to my home nnetwork.

	Today I was having problems reaching certain hosts (slashdot being one
	of them). I noticed that I could tracerout to a host 1 hop before
	shlashdot without a problem, but that traceroutes to is just got lost.

	So I looked at the routeing tables on that machine. here is wat I
	found!

	Can anyone tell me what is going on here? ed0 is the internal
	interface, and ed1 is the external. The real default route should be to
	24.6.61.1 What are all these others? Is this some strange sort of
	atack?

A new version of ALTQ that supports FreeBSD-4.0 is now available.

From README:
		ALTQ -- Version 2.2

						May 15, 2000

This is a release of Alternate Queueing for BSD UNIX.  ALTQ provides
queueing schemes required to realize resource-sharing and quality of
service.  The ALTQ release is intended to be a flexible platform to
promote network research and gain field experience.

Now that ALTQ is being developed in the KAME repository, this
standalone ALTQ release is back-ported from KAME, and supports only
FreeBSD-3.4R and 4.0R.  Other platform support (FreeBSD-2.2.8,
NetBSD-1.4.2, and OpenBSD-2.6) is available in KAME snap releases.
(some tools and documents haven't been merged into KAME, and are
available only in this release.)

What's New since version 2.1:
	- FreeBSD-4.0R support
	  - includes dc and ti driver support
	  - runs on alpha architecture (experimental)
	- tswtcm (time sliding window three color marker)
	- bug fixes

You can get weekly KAME snap releases from
	<http://www.kame.net>
You can get the latest ALTQ release from
	<http://www.csl.sony.co.jp/~kjc/software.html>
	or

	Good morning,

	I have an Xterm at home that I'm trying to boot
from my FreeBSD machine. It can either use NFS or tftp
to boot. Considering that I don't know much about NFS,
I decided to give Yale's tftpd (/usr/ports/ftp/yale-tftpd)
a try.

	It compiled just fine, but when I try to run it,
with tftpd -s /usr/home/tftproot/ , it doesn't return any
kind of message. Instead, I get a message sent to root that
tftpd is trying to perform a non-socket operation.

	Does anyone have an idea what I'm doing wrong, or
what could be wrong? Should I try to find another tftp
daemon? If so, a couple of suggestions would be largely
appreciated. Or should I just forget about tftp and use
NFS instead?

	Thanks for your time,

	MG_Tak

We're using ip_fastfowarding,  on a system routing 20k-30k packets per
second between two intel pro/100+ cards. When we enable it,  it causes
strange system behaviour;  System gets sluggish,  pauses from time
to time.  It may be because IPFLOW_MAX is set to 256.  We attempted
to change it to 8192,  but the system halts immediately after
enabling fastforward.

Can anyone advise how we can properly adjust varables in ip_flow.c?
(IPFLOW_MAX, IPFLOW_HASHBITS, IPFLOW_HASHSIZE, IPFLOW_TIMER, etc).

(We're using FreeBSD 3.4-STABLE, running BGP4 with 72,000 routes in
kernel).

Any help would be appreicated!

A much faster processor?

What kind of CPU/memory/network interface are you using?

Are you doing dns lookups?  Don't do those and you may fix your problem.

I am running two network cards detected ad "ed" on a
Micronics M5Pi PCI/ISA motherboard. One is a Lynksys
PCI and one is a Realtek ISA PnP. The OS is 4.0-Stable, very recent.
The PCI card is assigned ed0.
The ISA PnP card is assigned ed2.

I have two problems:
- the boot hangs
    this was fixed by adding "return 0;" in if_ed.c at line 905 in ed_get_Linksys(sc)
- ed0 says "ed0: device timeout" and does not seem to work
  I have tried "link0" "link1" and "link2"

I am a little suspicious of the IRQ, as it seems to be shared with
the video card, though they are both PCI.


Any ideas?

It may be too expensive, but we're using a switch/router that gives us 48
ports for < $5K US.  It priced out much lower than most chassis-based
units, and it has some nifty features.  You can give a "master" vlan an
IP, say a /24 and include other ports as "sub-vlans".  Each of these can
be bound to a port and either a range of IPs or a single IP.  It locks
people down pretty hard, and if they try to nab someone else's IP, they
simply drop out of the vlan.  There's really no need to do MAC-level
locking, as everything happens at the IP layer.  You can also flip a
switch to prevent users from even exchanging traffic with each other...
Very nifty, but maybe out of your price range, I don't know.

Hi,

IN my kernel, I have used some write() calls. But the compiler giving
warning messages saying that "implicit declaration". Once I boot this
kernel, whenever a write() call is executed, it is panicking. I guess it
is because write() is supposed to be used by kernel. What do I need to use
if I want the similar functionality as write()?

thanks

Thanks for all. 
I tryed all usual solution (change CPU, bring packet parsing out of reading
thread and so on.) and now 

I have stoped on perforamnce bpf itself. 

Is there alternate driver or can changing of bpf queue in kernel help, and where
I can read about it?

Did any body work with raw ethernet and is it helpfull?

Define "heavily loaded".  If you just run "tcpdump -n" for a couple
minutes and hit ^C, does it report any dropped packets?  If it does,
then your machine probably isn't fast enough to handle the network
load.  If I flood my 100mbit network with small packets, and monitor it
on a P6/200 with "tcpdump -n", I drop from 1-10% of the packets.  If I
use "tcpdump -n -w logfile.txt", I drop no packets.

There is a good discussion of mbufs in chapter 2 of "TCP/IP Illustrated,
Volume 2: The Implementation", W. Richard Stevens (ISBN 0-201-63354-X).

Hi, I have 2 network cards (pci 10/100 intel pro's) in a web server
running freebsd 3.4. I get messages periodically (at the bottom of the
email). This didn't happen before I put the second nic in. My ip set up:
209.183.78.161 	Gateway(router)
209.183.78.163	A Firewall
209.183.78.164	NIC 1 in Web Server
209.183.78.165	NIC 2 in Web Server
Everything is plugged into the same hub (Switched HP 10Base hub) and the
firewall has 2 nics with 1 of them plugged into the hub, the other doing
NAT for a private network. Anyone have any insight as to what these
'errors' might be? Thanks in advance.

The firewall has 2 nic's, one nic is connected to the public hub. The
other nic is connected to a seperate private hub using 10.10.10.x as it's
ip range. I think those entries from 209.183.78.163 are when I tried to
ssh in from behind that firewall. I don't think the firewall is coming
into play with those error messages though. Thanks.

	There is a good paper about "Networking Implementation Notes"
located at the /usr/share/doc/smm/18.net directory. Unfortunately, the
above details is not enough to give complete answer. Look also at Netgraph
interface.

Two possibilities come to mind:

1) You machine is too slow (pretty slow), your bus is too slow (ISA), or
   your cards are too slow (maybe if_ed).

2) You're using multiple processes/rforks to support the application,
   which results in a full context switch during BPF reads.  Instead, use
   our userland pthreads library.

Only you can tell us about (1) -- I can tell you I have successfully
snarfed 60+mbps (probably more like 70) off of two 100mbps interfaces
simultaneously with the CPU still quite low on FreeBSD 4.0, with a
moderately decent machine (400mhzish box).  There was no packet loss at
all, and I was pulling the whole packet off the wire, not just the header.
In this experiment, the limiting factors were the data-pumping machines,
not the sniffing machine.

Number (2) is interesting -- if I run two tcpdumps at the same time, I see
a huge loss of performance, as all copies from kernel to userland happen
twice, and many packet deliveries cause both processes to wake up and be
scheduled.  For high speed sniffing, using only a single process (i.e.,
just a relatively fast kernel->user1->kernel switch).  Preventing a full
userland context switch and making sure all BPF data goes through a single
process makes a big difference (measurements on a p166).

Hellow !!!

My test network looks like this:
 _____        _____         _____
|     |      |     |       |     |
| Win |------|Free |       | Win |
|  1  |      | BSD |-------|  2  |
|_____|      |_____|       |_____|

Configuration of Win1:
IP: 192.168.0.2
netmask 255.255.255.0
broadcast 192.168.0.255

Configuration of Win2:
IP: 192.168.0.201
netmask 255.255.255.0
broadcast: 192.168.0.255

Configuration of FreeBSD:
	Interface 1:
	IP: 192.168.0.1
	netmask: 255.255.255.128
	
	Interface 2:
	IP: 192.168.0.200
	netmask: 255.255.255.128

Problem:
I tried to set up PROXY-ARP for this two windows machines:
arp -s 192.168.0.2 <MAC address of Interface 2> pub
arp -s 192.168.0.201 <MAC address if Interface 1> pub

FreeBSD seems to publish both entries od ALL interfaces, so that windows
machine thinks that someone has taken the same IP that windows have.

Question 1:
How do i tell FreeBSD to publish ARP entry on only one card. Under linux
this is accomplished by -i option. 

Question 2:
How do i tell FreeBSD to do PROXY-ARP of network and not for specific IPs
?? Under linux this is acomplished by netmask option.

Thanks for answers..

bye, MadDave

Hallo
I have the following problem with my network configuration:
my normal routing tables is:
Destination      Gateway                 Genmask                 IFace
134.99.26.17     0.0.0.0                 255.255.255.255         eth0
134.99.26.0      0.0.0.0                 255.255.255.0   eth0
127.0.0.0                0.0.0.0                 255.0.0.0.      etho
0.0.0.0          134.99.26.1

(sorry that i'm using here route table from Linux, I can't mail from FreeBSD
because of network troubles)

IP is 134.99.26.17
Gateway is 134.99.26.1

the problem is that gateway 134.99.26.1 is behind firewall at the university
I can't use such things like ftp <-- for ports downloading, icq, real audio etc.
On purpose to make our student life better, our UniAdmin has made the second
gateway, we have to log in the second gateway with ssh and then we can use all
services like ftp etc.
The question is - how to add in FreeBSD the second gateway from the other
subnetwork ???

IP of second gateway is 134.99.162.254
I tried the following things:
route add -net 134.99.162.0  -mask 255.255.255.0  0.0.0.0
route add default 134.99.162.254
route: writing to routing socket: File exists

in Linux it worked always:
route add -net 134.99.162.0 netmask 255.255.255.0 dev eth0
route add default gw 134.99.162.254

thank you for your help

Hi,



No matter how many books/man pages I read, I can not find the
explanation for this error message:

ftpd[proces-ID] "getpeername (/usr/libexec/ftpd): socket operation on
non-socket"

On an other machine I got this too, until I changed ftp back to be
started from inetd (what I do not like at all, but at least now I can
use ssh and ftp on the same machine, with ssh being started from
rc.local) But when I change this on my other machine this does not
help...

Any help ?

Aernoudt

Hi!

As I'm going deeper into things as cable modems and that stuff, and have to
deal with the phenomenom PPPoE, could anyone point me to some resources
soing some detailed insight in this and practical appliances?

Is this standardized already in a RFC?
Heard some opinions from some guys that this is not standardized yet...

Anyone knows what OS is used in those "routers" for cable modems/DSL lines
manufactured by DLink, Linksys etc.?

I's RFC 2516 (http://www.ietf.org/rfc/rfc2516.txt)

> Anyone knows what OS is used in those "routers" for cable modems/DSL lines

You mean the router terminating this PPP ? I don't know the OS, but router
manufacturers like Cisco and Redback.support it.

ftpd assumes it has been started from inetd and therefore that file
descriptor 0 is a TCP-socket.  If this is not the case you get the

I repeat:  ftpd has to be started by inetd (or something inetd-like).

But if you steel want to run standalone ftpd try

# /usr/libexec/ftpd -D -4

It works for me.
