Hi, I see a problem with my linux m/c. After some hours i see that i can ping to my machine but telnet/ftp stops working. On the monitor display, i see that there is no login prompt. This problem is reproduced with/without X disabled.

I have to reboot to get it in working state and it hangs again after some hours.

There is no information in /var/log/messages for this problem.

Any tips/suggestions to troubleshoot this.
