Shortcut for login to remote computer via SSH

Question

I want to shorten my SSH login from my Mac computer to remote computer. Currently, I log in with

ssh [email protected].

I tried to replace the command using a short name in the cshrc file, but it did not work. How can I log in to the remote computer without having to type the full command above?

Answer 1

You can add a config file (no file extension) to your .ssh folder with the following entry:

Host x
HostName example.com
User me
IdentityFile ~/.ssh/key

Now, you can log in to example.com with the username me and private key key with the following command:

ssh x

Answer 2

If you want to have it "password free", you can use PublicKey authentification. It is one of the few concepts that is more secure and also easier.

All you need to do is create a keypair on the client and send the publickey to the server.

Create the keypair: (you should use a strong passphrase)

ssh-keygen -t rsa

Send your new created publickey to the server:

ssh-copy-id -i ~/.ssh/id_rsa.pub user@server

Now you should be able to login without a password. If not, make shure to configure your ssh server like this:

PasswordAuthentication no
UsePAM no

Answer 3

How about setting an alias in your shell's profile?

alias sshzzz='[email protected].'

Then you can just type sshzzz and then put your password in.
