The current version of openssh for 7.x, and this includes Alpha as well,
is openssh-2.9p2-8.7.  There were some security updates.  You can find
more on http://lwn.net/ and on bugtraq.  Check also Red Hat
annoucements on www.redhat.com.

Bad values in "known_hosts" files?  Messed up reverse DNS?  Blocking
needed ports on a firewall? Wrong routing? Some other misconfiguration?

You can find out more what happens in a setup phase if you will run
'ssh -v ....'.  Actually you may have up to three v's and
'ssh -v -v -v ...' will print _a lot_ of details on your screen.  You
may want to use 'script' to capture that all.
