Hi,

Quoting Steve Skoronski (skoronski@ctidata.com):

I have been thinking about that, seeing the high density of (non-WEP)
wireless traffic at HAL2001 :)

I have tried stuff like you're describing by putting my WiFi card in
'Master' mode, setting the essid to the network's essid.
I haven't gotten really far with this, also due to beer and other fun
things, but afaik it should work.
From the 'iwconfig' manpage, the section about 'mode':

|Set the operating mode of the device, which depends
|on the network topology. The mode can be Ad-hoc
|(network composed of only one cell and without
|Access Point), Managed (network composed of many
|cells, with roaming or with an Access Point), Mas­
|ter (the node is the synchronisation master or act
|as an Access Point), Repeater (the node forward
|packets on the air), Secondary (the node act as a
|backup master/repeater) or Auto.

So 'iwconfig eth0 essid "HAL"' and 'iwconfig eth0 mode Master' should do
the trick (probably the other way around).

Greets,
        Robert
