Router how to find port number for Web Management ?

zillah · 08-01-2010, 06:11 AM

Hi Expert

I enabled D-Link (DSL-502T) router web management (I am aware of security implication).

I was able remotely to login to the router (by typing http://23.45.xx.6y) before changing the default number 80.

Then I changed the port number from the default value 80 to 21908 ( https option is not available) for better security, and when i tried to login to the router by typing this :

http://23.45.xx.6y:21908

Yes I am aware that if I am physically near to the router then I can check that , but this is not the case with me.

How can i make sure that i had changed port number form 80 to 21908 ?

Does NMAP do a trick to reveal which port is used for web management ? or are there other better options ?

Thanks

Can you login using
http://23.45.xx.6y:21908 ?
You can use

Code:

nmap -p 21908 23.45.x.x
