Re: SSH connection problem
Make sure the name "garra" is defined to an IP address.
$ tcpip show host garra

Re: SSH connection problem
Could be almost anything. (It might even be
a real ENOENT, "No such file or directory"
complaint.)
> [...] OpenVMS 8.2 [...]
Actual output from
TCPIP SHOW VERSION
and
ssh "-V"
might be useful.
Knowing nothing, I'd start by adding "-v" to
your "ssh" command, to see if the program
will tell you anything.

Re: SSH connection problem
Are you looking for public-key files and maybe they aren't on both systems?
Did you remember to enable SSH service on the server that won't talk to you? You can still SSH out from a server with SSH service not running, because that service is only the inbound connection listener.

Re: SSH connection problem
$ TCPIP SHOW VERSION
HP TCP/IP Services for OpenVMS Alpha Version V5.6
on an AlphaStation DS25 running OpenVMS V8.3
$ ssh -v
Type garra$dka0:[sys0.syscommon.][sysexe]tcpip$ssh_ssh2.exe;1 -h for help.
but it's giving general help for TCP/IP.
Please suggest.

Re: SSH connection problem
-V gives verbose (debug=2) output. It needs to be quotes because DCL will make it lowercase if it isn't.

Re: SSH connection problem
You have to admire all the VMS-specific
effort that went into these programs.

Well, the C run-time library (and more lazy
VMS porting) certainly contribute. Many
other programs can obviate the quotation if
the user does SET PROCESS /PARSE_STYLE =
EXTENDED. HP's SSH programs are not on that
list.

Solution$ @sys$manager:tcpip$config
Then invoke this...
$ @sys$manager:tcpip$define_commands
Then post the output from...
$ whois garra
$ ping garra
Then work your way up to this command:
$ ssh "-v" garra

Re: SSH connection problem
I am able to connect to garra through ssh.
but I am getting following error

whois: rs.internic.net: Error 0
$ ssh "-V" garra

Re: SSH connection problem
> whois: rs.internic.net: Error 0
Apparently an old whois program with obsolete
server info. You could try
whois -h whois.internic.net xxx
but I doubt that anyone at internic.net will
know who (plain) "garra" is, so it's not
clear to me why this suggestion was made.

So, otherwise, you're happy now?

Just in time.
