Shortcuts to SSH clients

  • 772

I have many remote machines I need to log in. I need somehow store connection parameters because it is too boring enter them manually. Also I prefer to store password in these shortcuts. Software similar MTPuTTY that runs under windows would would solve my problem in Ubuntu.

How to solve this problem?

command-line

  1. You can do a lot using .ssh/config file. It would allow you to replace this:

    ssh [email protected] -p 22000

    with:

    ssh dev

    to do so you have to add the following lines at the end of the .ssh/config (create it if does not exist)

    Host dev
    HostName dev.example.com
    Port 22000
    User fooey

    Concerning the storage of your credentials, I strongly advise you to use key authentification instead of password based. You can create them either with a GUI or with your terminal.

    GUI

    open Seahorse, select File > New, then Secure Shell Key and let the interface guide you

    Terminal Create you RSA key pair:

    ssh-keygen -t rsa

    Store the Keys and Passphrase:

    Enter file in which to save the key (/home/demo/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):

    Copy the Public Key

    ssh-copy-id [email protected]

  2. If you wanted to, you could make short shell scripts to launch your ssh sessions, then execute them either as s executable ( chmod o+x), or using the dot . command

    Like make a file ~/ssh2hostA.sh

    #!/bin/sh
sshpass -p 'yourpassword' ssh user@hostA

    then start it with

    . ~/ssh2hostA.sh

    Which is not a good thing to do because not only do you have passwords in cleartext scattered in your files, but people will probably be able to see the password in the w command. ( and top, and /proc)

    Really, you should be using ssh host keys for this.

    Really.
