Hi Craig,
Are you sure that you did not install any of the ports around this time?
Usually you would see this type activity when a program is installed. You
should probably do a ps aux and sockstat -4 to see what is running and
open.

There are two programs that I am familiar with to monitor changes..
chkrootkit and tripwire. Chkrootkit is trivial to install but tripwire is
a much more complete package.

I am sure there are others here that can provide much more insight to
this.
Thanks.
Lewis
