next in thread | raw e-mail | index | archive | help
Heys, from -questions no one could find a solution for this problem... but
then again I was probably posting to the wrong list :-/
I've recently (2001/06/22) updated and rebuilt all my sources.
I have a Realtek 8139 and am running IPFilter as a firewall (ipf.rules at the
end)
I aint connected to a LAN.
Now the problem is that sometimes all my connections just start timing out,
even though my cablemodem has a fixed clean signal.
These timeouts happen randomly as far as I can tell and the only way to
regain my connection is by powering the cable modem off and back on and
running a restart DHCP client script that I will paste at the end of the mail.
In windows these timeouts do not ocur.
I have the same subnet mask in windows and in FBSD.
Now, I cought something through syslogd that seems to be the start of the
problem: Jun 29 12:34:11 <kern.crit> OpsyDopsy /kernel: pcm0: record overrun,
dumping 176896 bytes
I'll paste the whole log at the end of the mail.
The renewals are beeing applyed correctly (log at the end of the mail)
Besides this small problem the network works perfectly fine the rest of the
time.
I've cought something strange in a traceroute I made (the complete traceroute
is at the end of the mail) that was the first hop the packs pass is a
10.22.255.254 address when this should be if I'm not mistaken my default
gateway 213.22.3.254.
I will also paste a netstat -rn and a dmesg hoping these extra infos will
help.
I just dont know why these timeouts happen and hope someone can help me.
Thanks in advance for all your time.
JF
PS: I've already changed the NIC from a nearer to the lower part of the box
slot to a higher one... syslogd keeps giving the same error.
