ssh-keygen -t dsa
My understanding is that RSA keys are now the preferred method. It was, initially, RSA keys, then DSA, and now we're back on RSA keys (under SSH protocol 2).
It will then say "Generating public/private dsa key pair". Next it will ask you where to save the private key. We want the default so just press <enter>. It will now ask for a password. Don't set one. Aparently if you do it can't be used for our purpose. Perhaps someone knows for sure?
If you want keys that will not require a passphrase then don't enter one. Personally I just use the "-P '' " option on the keygen command.
After you've pressed <enter> twice it will give you some information about the keys it has generated. We now have to get the public key onto the server and put it in the right place. The easiest way is with scp :
Well, not initially, you haven't got ssh (or scp) working yet :-) Personally I telnet into the box and cut and paste from an X session. Failing that I've simply used a floppy in the past.
cat id_dsa.pub >> .ssh/authorized_keys2
Again, the use of 'authorized_keys2' has been surpassed by the use of 'authorized_keys' once more.
