It seems to me that sshd is definitely not running in your Red Hat box,
since it doesn't show in the process table. You may want to run the
following command and reply with the output:
ps auxw | grep sshd
If the daemon is not running, I'd check the /var/log/messages for clues as
to what is failing. Also keep in mind that putty may not be compatible
with ssh2. I don't know whether it is or not, I'm just bringing that up
as a possibility.
Other things that you can try:
telnet [redhatbox] 22
Does it even establish a connection to the server? It should time out
after a while because no encrypted keys are being exchanged, but it should
at least establish a connection through that port.
netstat | grep ssh
This other command should show if there is any daemon listening on port
22, and also if there is already any established connection.
Just a few ideas...
