1) How would you set up a secure passwordless login to a machine?

Am I on the right track with something like this: user1:x:100:10:Joe
User1:/home/user1:/dev/null ?

2) What would you do to find out what services are running on ip 1.2.3.4?

Would this work? netstat -a | grep 1.2.3.4

You can change /dev/null to /sbin/nologin, see man nologin.

It is better to use nmap:
nmap -O 1.2.3.4
(better as root).
