ssh to ssh2

[Cara Rollins]

i am setting up an ssh connection between two servers. server a has ssh - server b has ssh2. i have set up the authorized keys for both servers, but server b, running ssh cannot connect to server a running ssh2. Although, server a can connect to server b. Does anyone know what the issue may be? I have already combed through the ssd.conf files.

Have you tried "ssh -v"?

OS and/or ssh versions on these systems? The
key file formats on Solaris may be different,
for example.

Here is the debug output. I've removed any server specific info such home directories, IP and server names.

I am sshing from version
OpenSSH_3.8.1p1, OpenSSL 0.9.7d

to version
OpenSSH_4.2p1, OpenSSL 0.9.7d

Also, they are both TRU64 5.1 (not A or B)

[Steven Schweda]

I don't have any OpenSSH installed here
(Tru64 V5.1B, "ssh -V" says "ssh: SSH Secure
Shell Tru64 UNIX 3.2.0"), but it looks as if
the keys are being rejected.

Did you make the key files on one system and
copy them to the other?

If you make key files on the system where
you didn't do it before, do their formats
look like the first ones?

Compare with the "-v" output going the other
way?

Wait for helpful advice from someone who
actually knows something?

Hi,

It seems like you are running Tru64 SSH2 on one server
(...remote software version 3.2.0 SSH Secure Shell Tru64 UNIX...)

Do you have installed OpenSSH on both servers ?

If so can you try and use the OpenSSH's "ssh" command to connect from one system to the other ?

The command might be located here "/usr/local/bin/ssh"

Otherwise if you want to use Tru64 SSH2 "ssh" command you may need to set your ~/.ssh2/identification with the correct private key like this "IdKey name-of-your-private-key" and put your private key in ~/.ssh2

Cheers,
Kasper
