next in thread | raw e-mail | index | archive | help
I seem to have been having a rather strange networking issue in FreeBSD
5.3-Stable (it started happening immediately after 5.2.1 and has persisted
since.. I keep =B3hoping=B2 that next time I cvsup it will be fixed, but no).
I downgraded back to 5.2.1-p13 and it is perfectly fine once again.
*** Some background information:
My FreeBSD box is my home NAT router, server, firewall, etc. It does DHCP,
MX for some of my domains, secondary DNS (I got primary elsewhere), apache
for some webhosting, blah blah blah. Nothing really special. It is a Dual
PIII-500, 512mb ram, and a couple ATA hdd=B9s. Had 3 realtek network
interfaces, but down to 2 now.
*** The problem:
Networking simply "stops" or "locks up". Why, I don't know. I believe
initially it happened for all 3 network cards... I thought tcp/ip processin=
g
or something in the kernel got locked. It happens every 30 minutes to an
hour, and lasts about 60 seconds to 120 seconds. Unfortunately, 60 seconds
to 120 seconds is long enough to kill messenger (my gf does not like),
online gaming, etc etc.
Lately, I had taken one of the realtek cards out (it was for a several km
long wireless link) and moved the server to my gf's place (where I am now
100% of the time). So now that I have the server locally and rely on it for
my internet connection, this has become a real PAIN.
I've noticed that I can remain ssh'd into diablo, do whatever I want while
this "lock" issue occurs. So the lan interface rl0 is fine. The internet
interface, rl1 (which goes to the cable modem) locks up. (btw, its not the
cable modem as I am using my gf's now, and it did this at my place on my
cable modem too, which is a different brand. Nortel at my place, motorola a=
t
my gfs).
*** Attempts:
I've attempted switching out network cards, and places 3 other realtek card=
s
in. Different brands, all with different revisions (D instead of B, etc,
etc).
No matter what I try, nothing fixes it. The machine seems perfectly
repsonsive, and I am still ssh'd in and can do whatever I want on it... But
the network card going to the cable modem has stopped responding?!
This never happened during 5.0-Current all throughout 5.2.1-STABLE, but
anywhere beyond 5.2.1 it craps itself.

Dmesg output didn=B9t look particularly different in 5.3-stable. The coredump=
s
are due to the downgrade and being linked against newer libs from 5.3.

# Politely and quickly rejects AUTH requests (IRC!! #*()@$@#$)
add reset tcp from any to any 113 in via rl1
# Make the default 'deny' rule log too.
add 65500 deny log ip from any to any
diablo:/home/diskiller#
