One of those little handy-things-to-have is the ability to log into a remote computer without having to enter in the password every time.
To do that, we have to generate a pair of authentication keys for the computers A and B.
On computer A, make sure you have a folder called ".ssh". If not, create it.
- Type in "ssh-keygen -t rsa"
- Save it to "~/.ssh/id_rsa"
- Don't enter in a passphrase (just press enter)
- Open ".ssh/id_rsa.pub" and copy the contents.
Now on computer B, create a folder called ".ssh" (if it doesn't already exist).
Create "~/.ssh/authorized_keys" and paste in the contents of id_rsa.pub. Save and exit.
Now you should be able to connect from computer A to B without any problems.
