Hello,
Yesterday I had a strange problem:
I was unable to connect to my Linux box either using ssh or via serial
console, and even pop3s (secure pop3) was timing out. But I knew that the
thing is still alive because it routed packets to the internet from the
internal network, and I saw kernel messages appearing on serial console.
When I hit "reset" and rebooted it, the syslog was completely empty during
the period when it was inaccessible. I'm running RedHat 7 + 2.4.2 kernel on
ReiserFS.
So, I have a few questions:
1. Does anybody seen similar behavior?
2. How can I diagnose it?
3. My Linux box is headless (Intel server with BIOS support for serial
console, it doesn't have keyboard or display adapter). How can I send
SysReq or Alt-Control-Del via serial link? Is it at all possible?
Best regards,
Haim Gelfenbeyn.
