SFTP on VMS

I have been given a public key ssh-rsa
to a secure ftp server.
How do I load this onto my system to allow automated scripts to run to log on and transfer files.
thanks
Robert

Re: SFTP on VMS

Here's the no-password login sequence for ssh and sftp:

http://www3.sympatico.ca/n.rieck/docs/openvms_notes_ssh2.html

The biggest "issue" with any of this is ensuring that the "right" format certificates are used and loaded. Not all clients and servers all have the same sets of formats used for their certificates.

Here is the full documentation for ssh on OpenVMS using the HP TCP/IP Services ssh package.

And for debugging, most of the tools around have a "-v" or "-vvv" or similar diagnostic tool.

Google can be a good friend here, too.

That's nice, but my psychic powers are weak,
so I can't see it, so I don't know much about
its format.

How much do you expect us to know about the
SSH/SFTP software on "my system"?

Re: SFTP on VMS

the key looks like this?

ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAIEAwNw26SmCJIMND55gF7d38zG9lSVO3OjDJ4fJlRA5NF14v2f+k3Q/OENe+VeNmLhlmDcXCtZkV8/3xUiUUV0jV+h6fXH3WA3CqzY08xLFS6CRI+7zYUMyTn2bz

Ok. TCPIP, so the SSH2 key format is used.

That looks like an OpenSSH-format key, so
you may need to convert it to SSH2 format.

I think that the TCPIP ssh_keygen program
can _not_ do the conversion. An OpenSSH
ssh-keygen program should be able to do it.
