  My original question:

> As root, I issued this command:

> This only affects the machines ability to forward source routed packets. It

> You can still source route a packet through machine C to A, however.

I received two replies.
recommended installing the newest TCP wrappers.
recommends SOCKS 4.1.3
I guess my question was more theoretical then practical. We have a firewall
and a packet filtering router, but I was just curious about the host level.
Personally, I like TCP Wrappers a lot, but have little experience with SOCKS
to make any comparisons...
Thanks to those who replied.
