Hints & Tricks

The following two commands will set up password-less authentication from your computer to mycomputer.mycompany.com:

$ ssh-keygen -b 1024 -t rsa -f /home/username/.ssh/id_rsa
(do not enter a pass-phrase - leave it blank)
$ scp /home/username/.ssh/id_rsa.pub
username@mycomputer.mycompany.com:/home/username/.ssh/authorized_keys

Usually any problems encountered are down to the permissions of the various key files. Use ssh in verbose mode (ssh -v) and check the ssh daemon logs on both machines (usually /var/log/secure).

In using this method it is important for you to be aware of the security concerns that arise. The ssh-keygen command produced two files:

/home/username/.ssh/id_rsa: the private key
/home/username/.ssh/id_rsa.pub: the public key

You should ensure the permissions of the private key are -rw------- (i.e., only readable by the owner). This file is the equivalent of having a text file containing your login password to your account at mycomputer.mycompany.com; anyone who gets their hands on this file will be able to log into that account without knowing your password. However, any potential hacker must first gain access to your home computer in order to get at this file.
