Hi,
 I'm configuring ssh between a HP-UX11i (using OpenSSH_3.6.1p2, SSH protocols 1.5/2.0) and  an Alpha Server based on TRU64 using (SSH2, commericial version) but am faced with a slight problem. I have managed to successfully configure ssh connectivity from HP-UX server to TRU64 server but the problem lies from TRU64 to HP-UX. This is what I have done:

(1) Create DSA keys on TRU64 server (i.e ssh-keygen -t dsa..) with empty passphrase. This creates a 2048bit DSA paired private/public key.
(2) Copied the public key to HP-UX server
         - scp ~/.ssh2/id_dsa_2048_a.pub HP-UX:.ssh
(3) Converted the key on HP-UX server
        - ssh-keygen -i -f id_dsa_2048_a.pub >>authorized_keys2 (and also to authorized_keys)
(4) On TRU 64 server I added entry to identification file (IdKey id_dsa_2048_a.pub)

This is all the settings I have done on both the servers but when I test ssh connectivity from TRU64 server to HP-UX server, I still get prompted for password:

ssh -v HP-UX server -l <username>

ANY IDEAS what I'm doing wrong or what extra I need to do please.

thanks

have you simply tried adding the password after the username in the command to connect?

Have you tried to specify the private key name on the command line?  Like
ssh -i ./.ssh/id_dsa_2048_a  HP-UX-server -l <username>

Hi The Computer Guru 777, yes i tried that and am able to connect that way. Jharriss haven't tired that ANYWAY I have managed to solve the problem myself. The problem lied with the permission on the .ssh directory on HP-UX server. This was set to 777 I changed this to 755 and it works now so manythanks for your help.

cheers
