Out of pure curiosity, I scanned the external IP of my Cisco 891 and noticed the following:
Host is up (0.059s latency). Not shown: 65535 closed ports PORT STATE SERVICE 33333/tcp filtered dgi-serv I've never seen this before, and don't recognize the port number.
What's interesting is if I launch "telnet i.p.i.p 33333" -- it just turns blank, returns characters, but doesn't do anything, whereas if I were to do a "telnet i.p.i.p 12345" it just dies instantly.
I ran a "sh run all" and tried searching for "33333" or "dgi" but came up with nothing.
Has anyone ever heard of/seen this before?
Thank-you!
