Tenon Intersystems : SSH 1&2 for Xten 6.1

Please see text links at bottom of page for navigation

Secure Shell 1 and 2 for XTen 6.1

This package includes SSH1 and SSH2 for XTen. SSH2 is active by default. SSH1 compatibility mode is also on by default, allowing SSH2 client requests to SSH1 servers.

Secure Shell 2 Client (2.0.13) User Key Generation and Configuration

An XTen user creates public and private keys using the following command ("%" represents the shell prompt):

% /usr/local/bin/ssh-keygen -P

Private/public keys are created in a ".ssh2" folder inside the user's home folder:

id_dsa_1024_a

id_dsa_1024_a.pub
Create an "identification" file in the local ".ssh2" directory containing the private key file name:

% cd ~/.ssh2

% echo "IdKey id_dsa_1024_a" > identification
Copy the public key file "id_dsa_1024_a.pub" to the remote SSH2 host's local ".ssh2" folder (inside the remote user's home folder) and place an entry in the remote authorization file (~/.ssh2/authorization).

Secure shell may be invoked indirectly by checking the "ssh" checkbox in the remote client startup scripts or directly via the command line:

% /usr/local/bin/ssh xterm

Secure Shell 1 Client (1.2.27)

User Key Generation and Configuration

Invoke the /usr/local/bin/dossh1.sh script to switch the local client and server environment to SSH1 from SSH2.

Generate the RSA public/private key pair in $HOME/.ssh/identity:

% /usr/local/bin/ssh-keygen -N '' -b 1024 -f ~/.ssh/identity
Copy the public key generated by ssh-keygen (~/.ssh/identity.pub) to the remote machine (running sshd1) by adding its contents to $HOME/.ssh/authorized_keys file on the remote server.

To revert to the (default) SSH2 environment, invoke /usr/local/bin/dossh2.sh.

Optional Secure Shell Server

The Secure Shell server (sshd) is also in the binary distribution. To generate a host key for the server:

% /usr/local/bin/ssh-keygen -b 1024 -f /etc/ssh_host_key -N ''

Start the server in /etc/rc.local:

% /usr/local/sbin/sshd
