Ok, here is the scenario:
In the appartment I live, the internet is shared between 3 users.
Using router -D-Link 624i. One connection trough the LAN port & the other 2 using wireless.
One day is was doing upload etc. to a webpage, htm docs whatever. The other person that lives in the appartment (he is using the LAN port on the router) Unplugged my wireless card from my laptop ( God damn ) Because he was about to play a counter-strike match (Heh?) When I was out on a walk. Very ugly action. So in revenge, i blocked the ports (27000->) etc. on the router to block his CS playing.. Later on when he found this out, he reopened this ports, blocked some really needed port-forwarding to my pc, and changed the router password to something he only knows. In my point of view this is quite unmoral, since we all share the cost of the broadband. Ok, I can knock him in the face and force him to tell me the password (duh?) not my style. I can also reset the router, but then he will reset it again and change the password beacuse the router is in his room.
So, here comes the case:
Are there any way to sniff the password (when he connects to the router WWW-config) ?
Or, can I retrieve the password in any other way?
Retrieving the password means that I can forward my ports again, and when knowing the password, it is not unmoral (like when he is the only who knows the password)
And, (quite script kiddie, whatever) are there any way I can block the user from using the internet, as an revenge..?
Hope this doesn't sounds silly, but it's pretty annoying..
