DSL Ideas and Suggestions :: screen lock,firewall

I am new to dsl, since 0.9x have used puppy. In a large academic network I feel that puppy 1.07 has 2 things dsl doesn't: A screen locker for when I leave the office, and a simple firewall. But I love and use the ssh server a lot; something puppy doesn't have.

There is a simple firewall program called "rcfirewall" in the network section of the myDSL repository. It also may require "iptables" in the system section. I am not sure.

I am not sure about the screen locker.

Maybe "xscreensaverGTK" in the apps section will work?
