[Info-vax] VMS ssh client to freeSSHd on Windows

[Sum1]

Thanks to all those who helped, especially those who recommended 
editing the public keyfile to strip the VMS-style information - that 
appears to have got me over the hurdle.

The technique required was to generate a public/private key pair on VMS 
then copy the public key to windows, edit it to remove the VMS-specific 
format and make it like OpenSSH.  This entails removing VMS 
header/trailer information and the comment from the file, then removing 
the line breaks and appending ssh-rsa and a space - result, one long 
record with rsa-ssh and stuff.  This modified file is placed on the 
freeSSHd server where the publik keys reside (varies by installation I 
am informed).  It means the Windows and VMS publiv keys are in 
different formats.  Trying to do an ssh-add of the windows-format key 
will fail, so let windows keep its format key and VMS can keep its own 
format key.

Now, one last problem - of course!  Following is the output from an ssh 
connection, note that the authentication is fine (apparently) but the 
session immediately dies.  Googling for help on the message is - 
unhelpful.  VMS expert opinion greatly appreciated.

Cheers
