This will generate an SSH key of the appropriate type. It will ask you if you want a passphrase; press enter to use a blank passphrase. Accept any other defaults presented to you. 2) You will now have a directory ~/.ssh . In there will be two files (at least): id_dsa and id_dsa.pub. The latter is a public key, the former a private key. 3) Copy id_dsa.pub to machine B. To do so, type scp ~/.ssh/id_dsa.pub [machine B's name]: Note the trailing ':'. 4) Connect to machine B: ssh [machine B's name] 5) Put the contents of the public key (id_dsa.pub) in ~/.ssh/authorized_keys on machine B: cat ~/id_dsa.pub >> ~/.ssh/authorized_keys Note that ~/.ssh may not exist yet on machine B. If it doesn't, you'll get an error from that last command, and you'll need to create a new directory -- mkdir ~/.ssh -- first. -- Stephen R.
