So VMS is the SSH server.

[Jan-Erik is right; normally, when one talks about a "remote" system,
the default implication in this type of discussion is _that_ system is
the server and hence is the one being accessed, as a server, from a
local client. That's what I assumed as well.]

Some questions:

Are all accounts (both successful and unsuccessful) being accessed from
the same remote Linux box ?

Have you _actually_ done a $ show int after a login failure ?

What's the final status in the accounting log for the login attempt ?

For an account which you cannot log into from a Linux client, can you
login to the VMS server from a _VMS_ SSH client on another box ?

To turn on debugging in the Linux SSH client, use "ssh -v" on your
Linux command line. Increase the number of v's above (as in "ssh -vv"
or "ssh -vvv") to gradually increase the amount of debugging information.

If that doesn't reveal anything obvious, try the same for a successful
login attempt and see where things start to differ.

Simon.
