Setting up passwordless logins-SSH

May 8, 2012 by ·

First step is to generate keys on the machine from which you will be connecting (the parasite)

ssh-keygen -t rsa[/code]


Now, a key pair will be generated, of which one will be private key (Default: id_rsa), and the other will be the public key (Default: id_rsa.pub).












Now we need to copy the public key to the machine into which the parasite will be connecting (the host). You can either use a web interface for adding the keys, or directly use the following command (which will prompt you to input the ssh password you have now):


ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]_of_host[/code]


Eg:


ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected][/code]


[email protected]'s password:

Now try logging into the machine, with "ssh [email protected]'", and check in:


~/.ssh/authorized_keys


to make sure we haven't added extra keys that you weren't expecting.
