SSH without password

[Michael Sullivan]

I've got two computers, a server and a client.  The server doesn't have
a monitor hooked up to it, so I always access it from the client through
SSH.  I want to be able to ssh over to the server from the client PC
without having to type in my password every time.  I scp'd my
~/.ssh/known_hosts file over to the server, but it still asks me for my
password every time I log in over there (which is quite often
actually.)  What else do I have to do to avoid having to enter my
password every time?
