Script for ssh automatic login to a specific port

Question

So currently, the "traditional" way to connect through SSH is the following one:

ssh USERNAME@HOST -p PORT

I would like to create a script in which I will include all the appropriate information (username, password, host, port) and when I run it, it will connect automatically leading me to the shell of the host machine.

I don't care about the language you will use (e.g. Python, Perl...). I have tried to create it using Expect but unfortunately it didn't work for me.

Solution

For automatic login, the way to go is using key-based authentication.

A nice tutorial here

You can then use the default one (the one in the ~/.ssh/id_rsa ) or use another key passing -i MyKeyFile parameter to ssh.

[lese]

is for your self? create a bashrc alias

[smw]

A better option might be to use the user's ~/.ssh/config file + key-based authentication

you are right, I didn't think about it
