SSH Without Key with a simple Command

We all know that ssh can be make to login via ssh keys. SSH offer a secure alternative to endlessly entering a p@$$word: public key exchange.

To use public keys with an ssh server, you'll first need to generate a public/private key pair:

#ssh-keygen -t dsa

command, and then transferring the public key ( ~/.ssh/id_dsa.pub) to the target machine and copy it under target machine's .ssh folder by the name of authorized_keys.

By exchanging the keys we had just put some charge (speed) in the SSH process. So less time is spend in login so more time for troubleshooting.

But still, I am not happy

I still need to type:

#ssh server-name

to get into the server. NOW, I don't even want to type "ssh server-name" (lazy I am )

How to achieve this?

Here is a small HACK !!!

Create a file called ssh-to with these two lines in it (under your home):

#!/bin/bash   #ssh `basename $0` $*

Now put that in your PATH (if ~/bin doesn't exist or isn't in your PATH already, though it should be ) and set up symlinks to all of your favorite servers to it:

Make the ssh-to file executable:

#chmod 744 ~/ssh-to

Now create a directory bin under your home.

#mkdir ~/bin

Go to the bin directory and create a symbolic link, as shown:

#cd bin

#ln -s ssh-to server-name

  your job is done.... now simply type "server-name" and with all the magic you will be inside the "server-name" without typing "ssh server-name"

MOST Interesting is that you can also execute some remotely without actually landing on the target server - server-name 

    #server-name some-command
