The short answer is: No, at least - not with this port (OpenSSH v3.7.1p2).  Also note that it's only the sftp and scp *CLIENT* that works under MPE/iX.  (i.e - All connections and actions are initiated from the 3000)

The longer answer is: With a bit of work, probably yes.  IRRC - the issue is that 'select' is busted under MPE/iX, and that's what's required for ssh to work correctly.

It's been quite a while since I looked at the code, so I could be mistaken - but the fact remains - ssh cannot connect to a remote system - and execute commands that produce any output.  Ken Hirsh did the original port, but only really needed the sftp client - so the issue w/ssh wasn't addressed.   

Ken also posted on the 3000-L on 29-Feb-2009 - asking essentially if there was any interest in getting a ssh and sshd/sftp-server working (server daemon), so the 3000 could do port forwarding, act as a sftp server, receive inbound ssh connections, etc - but apparently didn't get enough response to carry forward publicly.   Of course, he might have done something privately - and we just never heard about it.  ;-)

There's another option, though.  OpenSSH isn't the only implementation of the ssh/sftp/scp protocol, although it is arguably the definitive open source one.  That said - in my 'copious' spare time, I'm working on porting the 'dropbear' ssh application.  It's much simpler, and much more restrictive - but appears to have a much greater chance of success than having to significantly rework OpenSSH to make it work under MPE/iX.  

Unfortunately, the current OpenSSH port meets my client's needs - so if I want to spend any significant time on the dropbear (or other) ssh packages - I'll need a benefactor or two.  (HINT, HINT, HINT).  ;-)

As always, if you have questions - don't be afraid to ask.  If you have some spare time, try putting up sftp (from Allegro or MPE-OpenSource), you'll find it suprisingly easy.
