Carry Private SSH RSA / DSA Key For Connection Using Unix / Linux Shell Script

by

To carry a private SSH RSA or DSA key for a connection using a Unix/Linux shell script, you can use the ssh-add command. The ssh-add command is used to manage the authentication keys that are used for public key authentication.

Here’s an example of how to use the ssh-add command in a shell script:

#!/bin/bash

# Add the private RSA or DSA key to the authentication agent
ssh-add ~/.ssh/id_rsa

# Connect to the remote host using the private RSA or DSA key
ssh user@remote_host

In this example, the private RSA or DSA key is located in the ~/.ssh/id_rsa file. The ssh-add command is used to add the private key to the authentication agent, which manages the authentication keys that are used for public key authentication. The ssh command is then used to connect to the remote host using the private RSA or DSA key.

Note that the ssh-add command should be run in the same terminal session as the ssh command, since the authentication agent only maintains the keys in memory for the duration of the terminal session. If you want to persist the keys across terminal sessions, you can use the ssh-agent command to start a persistent authentication agent.

By using the ssh-add command in a shell script, you can carry a private SSH RSA or DSA key for a connection, allowing you to automate connections to remote hosts without having to enter a password each time.
