My TM supplied router - TRG212M, port 1050 is open by default. Any idea why?
Right now, I'm port forwarding it to non-existent PC...
I did further checking on port 1050 on the TRG212M. It's a web server running on port 1050. Very interesting.Right now, I'm port forwarding it to non-existent PC...
118.100.67.125 is a random TRG212M I found on the internet. Can't login, known operator and admin passwords do not work.
CODE
$ telnet 118.100.67.125 1050
