I selected the Airport or Airport Extreme in Active Mode instead of
the Airport in Passive Mode and it seems to have worked fine.
Others with the same problem should try this.
Hi Bob,
That is a fair suggestion for anyone who just wants basic scanning.
However, passive mode scanning has substantial advantages to active
mode scanning. Essentially, active mode scanning sends out a flood
of queries and listens for the responses from routers, while passive
mode scanning simply monitors the various frequencies, one at a time,
to try and pick up transmissions which the wireless access points or
other computers are sending anyway. This means that active mode:
- has more limited range (i.e. only routers which are close enough to
receive the signal from your computer will be picked up)
- will detect fewer networks (since some routers will not respond to
the queries your card sends out)
- can be detected and logged, complete with your MAC address, by any
other device in range (including other people running KisMAC in
passive mode!) - this is important in states such as Florida where
the laws have been so stupidly written as to make any type of
scanning technically illegal
- cannot distinguish between different types of encrypted network
- cannot be used to capture packets for the purpose of testing
network security (although at the moment Airport Extreme Passive
appears to have some problems with the integrity of packets it
captures, so may not be as useful as other passive devices for
security testing of networks)
By all means, active scanning is a decent way to pick up many
networks, but given the choice between active and passive scanning,
there are many reasons why it is worth the effort to get passive mode
scanning to work.
Cheers,
Robin
