Should I be concerned, or is this maybe part of portsentry or something similar?

No idea.  nmap, amazing as it is, isn't the only tool you need though.
Try running 'netstat -ntuple' to see which programs are actually
listening, according to the kernel.  Of course, netstat could have been
replaced with a trojaned version, and your kernel could have been messed
with, but, otherwise it'll show you what programs are listening on
your ports...

Looks like it may just be part of portsentry. Thanks!
