How to find computer names from adhoc ssid

Hi,

If I see an ad-hoc network does it exist a clever way to reveal the
computer names involved? With or without connecting?

Thanks for tips on this, hardware or software

regards

The WiFi SSID is at the lower level of connection.
To be able to see the Windows computer names,
you have to move up about 3 levels.... to the Windows sharing world

lowest - WiFi or Ethernet connection
then get onto the network segment (tcp/ip)
then look for the Windows application sharing broadcasts,
which will have the "shared" computer workgroup name

Does it exist tools (free or commercial) which does the job of trying to
connect (or sniff an existing session) to display such details as
computer name etc?

Otherwise we welcome other approaches to trach down unwanted wireless
communication in a student exam setting ;-)

Tell us more about your situation and world location ??

Are computers allowed during the exam ?

The Windows computer name broadcasts
would only exist IF the person enabled Windows "sharing".
But they still could be communicating without having sharing turned on...

You could indicate that ALL wireless must be turned OFF,
and if you see any SSID broadcasts - that would be a problem.

What about them also using smart cellphones & texting to each other ?

We're in Scandinavia.

Personal computers allowed containing any resources which the students
have collected and saved before the exam.

During the exam, no communication to/from the computers are allowed.
Cellphones are collected and kept until the students are released.

Do you have any example of software which can be used to sniff into
filesharing to reveal computernames or other info which may indicate
from which computer the activity comes from, like MAC addresses etc?

thanks for the info -

like I mentioned...
the "computername" would NOT show up in ALL/certain circumstances,
even though the user could be communicating with another user.
The "computername" is only "broadcast" if that computer has "sharing" turned
on,
else - since there is nothing to share (files, sub-dirs, printers, etc) - no
broadcast is issued.

The simple solution would be to just announce "all wireless should be turned
off or disabled" -

Run a computer looking for just normal adhoc SSID's avail connections,
and go from there....
or - run something like NetStumbler to see all avail connections...
