Apparently my home router is listening on port 5001:

Nmap scan report for (
Host is up (0.018s latency).
Not shown: 997 closed ports
80/tcp    open  http
5001/tcp  open  commplex-link
52869/tcp open  unknown

I tried googleing for port number (5001) and protocol (commplex-link) but couldn't find any clarification.

Does any body know what is that protocol or if it exists as a standard? Link to documentation would be nice.

  • What sort of router it is would help - also while its a well known port, ports are not always used for the registered protocol... so it might not actually be "commplex-link" – Journeyman Geek Jan 22 at 2:08
  • I agree, and thus I don't think it matters which router it is. I just want more info on the protocol itself. If nmap catched it I think it cannot be so "unknown". Nevertheless I couldn't find it. – harogaston Jan 22 at 2:12
  • It matters here simply because someone else might have come across it - alternative fun stuff to do is try using telnet and seeing what the response is... but if its something 'unique' to that router, it would narrow it down. – Journeyman Geek Jan 22 at 2:24
  • for example - wikipedia suggests slingbox/slingplayer and synology use it – Journeyman Geek Jan 22 at 2:25
