I have a box that I'm admining that is several hundred miles away with a novice linux user at the helm. Until today, she was fine on the net and had 0 problems.. but suddenly she couldn't email or "surf the web".
I tried to connect to her machine, and that was a no-go -- I get about 97% packet loss (42 packets transmitted, 1 packets received, 97% packet loss).
I tried small things -- "rcdhclient restart" -- which worked as it should but still didn't fix the problem. I had her go into yast2 - network/basic - and restart her whole network subsystem, which didn't work either.
Misery loves company (I hope)... I've had similar happen a couple of times in the past few months (SuSE 7.2). I examine my /var/log/messages and even my usually-noisy ISP probes are dead... Most recently, this "dead network" happened near 3pm one weekday - the system was idle, with no users or anything. Some outside person had tried 3 or 4 ftp connections (I have no ftpd running, and port 21 is blocked anyway), then shortly afterwards my net connection was dead (can only estimate to <~10 minutes accuracy). I don't think this outside connect-attempt is really relevant, except as a time-stamp. I haven't tried pinging 127.0.0.1, but I *have* tried pinging yahoo.com, with no response. Couldn't log in remotely, either (SSH on port 22). Like you, I tried restarting network stuff (rcnetwork restart, inetd HUP) and I brought my eth0 down, then up. No luck. I did have to do a re-boot... My current line of thinking is that somehow my firewall is getting wedged up, and blocking everything. I haven't tried restarting SuSEfirewall, but it's on my plan for the next time. -Gord (not really much help, still puzzled) -- Gordon Pritchard, P.Eng., Member IEEE Technical University of B.C. - Research Lab Engineer mailto:gordon.pritchard@techbc.ca direct phone: 604-586-6186
