I just downloaded and installed ssh-2.3.0 on a Redhat 6.2 box.  The install 
seemed to go fine.  I created public and private keys in the home directory 
of the user I log in as and I made sure sshd is running but I can't seem to 
connect to it from a windows machine.  I tried using Putty and it pulls up 
a window then disappears without an error message.  I tried TTSSH and it 
gives me this error message:  "This program does not understand the 
server's version of the protocol."

I'm an ssh neophyte - can anyone give me a pointer?

Thanks,
Brady
