I am having issue with establishing connection between two different versions of secure shell. Please help me on how to generate keys that will work for between these two versions and also how to set up the files on remote and local server?

Hi, can you please include version numbers for both client and server in use?

(Jun 22 '11 at 21:13) Roman ♦♦ Roman's gravatar image

On client: $ man ssh sshg3(1) NAME sshg3 - Secure Shell terminal client - Generation 3

On Remote: SSH(1) NAME ssh - OpenSSH SSH client (remote login program)

When i try telnet to find the versions of secure shell: $ telnet Client 22 Trying ipaddress... Connected to client. Escape character is '^]'. SSH-2.0- SSH Tectia Server

$ telnet Server 22 Trying ipaddress... Connected to Server. Escape character is '^]'. SSH-2.0-OpenSSH_4.3

ok thanks. You can also find out the version of the client by running the "sshg3 -V" command.

(Jun 22 '11 at 22:02) Roman ♦♦ Roman's gravatar image

On Client: $ sshg3 -V sshg3: SSH Tectia Client 6.0.5 on x86_64-unknown-linux-gnu Build: 7 Product: SSH Tectia Client License type: commercial

On Server/Remote: $ sshg3 -V -ksh: sshg3: not found [No such file or directory]

Have you tried this answer?

Alternatively you could also generate the key using OpenSSH tools and import the public and private keys to Tectia Client.


So you basically have two options:

Option 1

Generate the key pair on the client host (running Tectia Client) and upload the public key to the OpenSSH server as outlined in here.

Option 2

Generate the key pair on the OpenSSH server host and copy both the private and public keys to Tectia Client under your $HOME/.ssh2 directory.

These are all assuming that what you are trying to do is setup public key authentication from the client (running Tectia) to the server (running OpenSSH) and not viceversa.

I tired creating the keys on both the servers and passing them over to other server. In both the approaches I allways had the private key on client and publick key on server.

Did you follow the steps in the linked answer from above exactly? If so, what error do you get when it fails? Also please check the server log on the OpenSSH server for any errors.

Thanks Roman... I have done that and it works without giving the password. But I am faicng issue with: Host key for the host "Remote-server" not found from database. This causes failue for me in scripts as it keeps asking input to save the new fingerprint everytime i do sftp/ssh. But when I tired to compare the the fingerprint of the key stored in hostfiles folder on ssh2 and to that of openssh publick key they completly differe in format.

Please help me to fix the issue: Host key for the host "Remote-server" not found from database.

Good to know that was resolved. Could you rather enter this as a separate question? and include if there if it's the same setup (Tectia Client on Linux against an OpenSSH server) or something different.
