Hi All,
I've got a machine with the following description:
Dell Precision 530
Fully patched fedora
Dual P4
Alteon Gigabit nic
Services running: sshd, vsftpd, apache
Periodically, it goes (mostly) dead. It looks like this:
I can ping it.
I can nmap it, and the services are all detected
I cannot connect to any of the servers via a client (ie, ssh, ncftp, moz)
I can telnet to the appropriate ports, and get connected. (I forget how to
make an http server spew to a telnet client, but I've done it before)
Both the terminal (through kvm) and console (serial, through to a
concentrator on another machine) are dead in the water.
Are you using an nvidia video card with the binary drivers? This
happens to me sometimes, and I suspect the video drivers. When I
ssh/telnet into the "hung" box, X is taking up 100% of cpu. If I do
this everything starts to work again:
---
killall X [just to be sure]
killall -9 X
init 3
[wait 5 secs]
init 5
