lsof -i doesn't show any of those five ports.  It seems to show the same
ones as sockstat.  I should have mentioned previously that I verified
the tcp ports were open with nmap, but that wouldn't tell me what they
were.  I haven't figured out how to even verify the udp ports are
connected or open.  I also should have mentioned that I don't have any
reason to think that my system is infected, but I just wanted to
understand the difference.

Thanks for the reply.  I had completely forgotten about lsof.
