rcmd: ssh: unknown host

Joseph V. Caputo — Mon, 08 Dec 2003 16:22:19 GMT

running HP secure shell. I can ssh into a server but when I try to go from there to another I get the error:
rcmd: ssh: Unknown host.
Host name, IP resolves just fine.

Did you try doing "ssh ip_address"?

Can you ping that server? If you can, check to see if "sshd" is running on that server you are trying to ssh into. Let me know.

Yes sshd is running on the other servers and they are all pingable

The message is strange: rcmd is complaining it doesn't know a host called ssh.

Could it be that you try to do something like rcmd ssh , resulting in rcmd trying to connect to the host ssh to run command ?

(I've tried, and I get exactly this message if I do:
'remsh ssh dummy>')

Strange thing is that ssh complains of unknown hosts with another string: 'no address associated with name' is what you get if the host is not resolvable by ssh.

So I think you need to do:
type ssh
And perhaps 'which ssh' too.

Just to make sure there is no alias or something else that is called ssh and is run instead of the real ssh on the server giving the error.

I copied just the ssh executable from another system and it's working fine now.

You don't have the old version? Seems to me some 'joker' has copied remsh to ssh on your system...

You could also touch /etc/krb5.conf
