I recently installed wireless networking (802.11g) in my workplace.

How can i come to know who is connected to my wireless AP at present?
Similarly can i come to know who( MAC address ) was connected to AP in
past , or who tried to connect this AP?

AP is acting as DHCP server also.Can anyone suggest suitable wireless
network mgmt tool which can help me.

Well, if your unspecified hardware supports SNMP, the list of
connected MAC addresses is easily available.  If not, there are ways
of sniffing the LAN for new MAC addresses such as Ethereal.

Search Google for "Wireless Intrusion Detection".  There are quite a
few listed.  If you just want something simple for Windoze, see:

I don't have a huge amount of experience with AirSnare, but it does
seem to work.  My main complaint is that it requires that a monitoring
PC be turned on all the time.  I prefer sending the collected data to
a syslog server, and analyzing the results at my non-existent leisure.

I'm not sure you would want "who tried to connect".  When I do that, I
get every passing wireless PDA, neighbor, war driver, and such.  It
also requires that the sniffing be done on the wireless side of the
bridge.  A connection attempt, with no success, will not show up with
any packets on the wired LAN side.  Basically, the MAC address
sniffers only detect successful connections (those with correct
WEP/WPA keys).

You can block access using our free WIFI internet access blocker
software - see http://www.myWIFIzone.com When you have blocking turned
on, you get a message showing IP and MAC address of blocked computer.
It doesn't log anything yet - maybe a later version.
