FC5 - Drops ssh connection

[Arun Biyani]

Hi Folks,

I recently downloaded and installed FC5 on a PC. This PC is connected
to a hub. I have another PC on the same hub running Windows XP. I would
like to access the FC5 PC from the XP PC in various ways (telnet, sshd,
vnc).

After installing FC5, I did a "yum update" which finished without
errors. Using chkconfig, I've removed services which I do not need.

 From Cygwin, I logged into the FC5 PC (192.168.10.80). As you can see,
the ping went well. First time I tried ssh, it did not respond. So, I
walked over to the FC5 PC and as root "service network restart". The
ssh was then successful. But after a few minutes, the FC5 PC drops
the connection. Same thing happens with telnet & vnc. "dmesg" does
not reveal any new messages. My ~/.xsession-errors does not have
error messages.

How do I go about fixing this problem? What should I try? Firewall,
iptables and SELinux are all disabled.

Thx
Arun
