Thanks for your help,
I just turned sunprc off. This is on my firewall
machine and I'm not using NIS or NFS. If I don't
need it, I figured I might as well close it.
One more thing,
This is my home machine and since getting laid off
I don't have much need to ssh into it from the
outside. I was wondering how I can get it to
only accept ssh connections on the internal
interface.
