OK, I have a fairly sizeable list, but it looks like most stuff is
bound to 192.168.1.84 except two things, one is closed, and the other
is syslog (guess I have to look at it's man page). It also looks like
there is something else there. I guess I'll be looking at the netstat
man page to figure out how to get the name of the daemon touch it:

 > netstat -f inet -a; netstat -f inet6 -a
