Connection failure to an OpenVMS SSH server

Connection failure to an OpenVMS SSH server

Hi!

I get "Access denied" when attempting to log into an OpenVMS
SSH server. It work with another SSH client ( a command line one ).

Here is the log of the working session :

1. Installing ssh server on OpenVMS?

Hello:

I'm in the process of finding out what is involved in getting ssh
running on my OpenVMS box(es).

This seems fairly intimidating, mainly because I'm not that familiar
with VMS. Our usual VMS admin has been attached to another project and
I'm filling in, but am not comfortable in the OpenVMS environment.

I've found the ssh server that David Jones has developed, and I'm
working through finding out if I have all of the system tools I'll
need to build it on my 6.2 and 7.1 systems. I do have a few questions
though.

 While most of the docs for the OpenVMS ssh server suggest using
 SSLeay, there are a few notes that refer to OpenSSL (0.9.5a). I read
 the INSTALL.VMS notes for OpenSSL 0.9.6a: it looks somewhat more
 involved than I had hoped, particularly the OS version troubles.

 - Is one SSL easier to install that the other (SSLeay vs. OpenSSL)?

 - Is one SSL more secure than the other?

 - Is the VMS ssh server subject to the CRC32 exploit?

 - Is this server being actively maintained?

 - Are there any alternatives (portable OpenSSH)?

Before I even get to that point, I need to put the tools in place to
compile the source.  At present, I'm pretty sure I don't have a C
compiler installed on either system. I'm trying to find out about DECC
and whether we still have a site license or not. OpenSSL mentions that
it can be compiled by either DECC or GNUC.

 - If I install GNUC to compile the SSL, will the SSH server also
   compile with it?

I suppose that what I'd like is an installation cookbook, with the
process laid out in a step-by-step manner. In the meanwhile I'll keep
groping my way through Digital's docs, the included notes and the
online help.

Thanks in advance.
