SSH using public key
Normally when I ssh to a host, I use a command like ssh name@www.host.org and it will prompt for a password and then I'm in. If you use a public key, you can generate it with
$ ssh-keygen -b 512 -t dsa
where -b 512 could be 512 or 1024 bits in length and -t dsa could be dsa or rsa. So, after doing this, you can now ssh to a host with just
ssh www.host.org
and it won't even prompt for a password (security risk) as long as you don't give it a passphrase when it prompts with ssh-keygen. You may want to read up on this or man ssh-keygen for more help.
