How to see network password while logged into that network

Splave · #1 07-15-2010

Is this possible? someone lost the network password but there is still a computer connected to that network. Is there a way to show the network password while connected?

This is for wireless inter-office internet. Router is off limits, the office manager is the only one with the info and is on vacation for a week!

What os? Vista and 7 yes. XP not really unless it uses networking software other than M$ zero config.

Failing that, if it is WEP you can crack it in a few hours to a day usually, just need a wireless machine sitting within range running airsnort WPA is a lot tougher but probably doable by now.

Not that I have ever done it mind you, just for informations sake I have read up a little on wardriving back in the day.

wow is it really that easy to crack? free internet ftw

Air Snort (Linux app) does it a good bit faster for WEP, and probably does WPA and WPA2 by now.

Gotta run Linux iirc... I doubt there was ever a Windoze version developed that was any good. I haven't seen that proggy in years though.

Yeah and it only works with certain wireless chipsets. Cheaper it is the less likely it will woirk with linux/airsnort.

Here is more info for running on windows
