SSH fails after idle for some time
Here is a suitation.
I restart my Suse linux box.
Then, I ssh to this box from another machine.
After a while say after few hours, If the try another ssh session, I get "Server unexpectedly closed network connection" error.
Somehow I figured out that sshd was not starting due to daemonPRNG not seeded.
I recreated /dev/unumber and "daemonPRNG not seeded" issue disappeared. But still I am not able to restart sshd.
If I keep the session busy, say run a top command, then sshd is up, and I am able to log it untill the top is running.
Basically, I beleive the ssh timeout is shutting down sshd and after this I am not able to restart sshd.
