unexplained network problems
Running woody on a lan using another box - 192.168.0.1 as the gateway. The
debian box runs samba as do two other nix boxes. Last night everything
seemed fine, this morning for unknown reasons my debian box doesn't seem to
be able to talk with anything else.
Can ping myself by name, network ip, or as localhost but ping attempts to
other boxes hang. An ifconfig -a shows the nic up and running, with 0 RX
packet errors and 1311 TX packet errors. A netstat -rn shows two entries,
one for my class c network and one for my gateway which is win xp.
destination gateway genmask flags iface
192.168.0.0 0.0.0.0 255.255.255.0 U eth0
0.0.0.0 192.168.0.1 0.0.0.0 UG eth0
Here's what happened next: # as root of course - manually copying from the
console
ifconfig eth0 down
rmmod tulip # using this driver for my netgear fs310tx nic
modprobe tulip
/etc/rc.d/networking restart
bash: /etc/rc.d/networking: No such file or directory
route add gw 192.168.0.1
gw: host name lookup failure
ping 192.168.0.1
ping: sendto: network is unreachable
The light for this nic on my switch was on and blinking so I removed it and
reinserted; stopped blinking, went through the commands above again with
similar results and then rebooted.
Everything is ok now.
Only I feel like an idiot. What happened and how did I fix it? Had a
problem with this box's connection a few weeks ago too, which is how I knew
the steps to try and recover. Any pointers on how I can educate myself to
at least understand what I'm doing - not to mention get a clue about what
problem is bringing my network down every couple weeks would be most
gratefully accepted.
