Users connected to an Access Point

Hello, does anybody know if there is a tool to easily detect all the
PC's (their IP & MAC) that are connected to a wireless access point
and what bandwidth each is using?

Thank you very much

Assuming that you are using a Cisco Aironet AP, then just use the command
"show dot11 associations all-client".

Assuming that you don't know what kind of AP you have, then there is
no general answer to your question.

Such information is usually extracted directly from the wireless
access point via SNMP or proprietary managment software. Sniffing
traffic between the wireless access point and router will not yield
this information. Some clue as to what you have for hardware might be
helpful.

Bah-humbug. Use SNMP instead. Using SNMPUTIL.EXE from:
<http://www.wtcs.org/snmp4tpc/testing.htm#SNMPUTIL>
pointing to my WRT54GS running DD-WRT v23 SP3:

List of connected IP addresses:
snmputil walk 192.168.1.1 public .1.3.6.1.2.1.3.1.1.3.1.1
which returns:

Variable = at.atTable.atEntry.atNetAddress.1.1.63.249.85.1
Value = IpAddress 63.249.85.1

Variable = at.atTable.atEntry.atNetAddress.1.1.192.168.1.11
Value = IpAddress 192.168.1.11

Variable = at.atTable.atEntry.atNetAddress.1.1.192.168.1.51
Value = IpAddress 192.168.1.51

Variable = at.atTable.atEntry.atNetAddress.1.1.192.168.1.113
Value = IpAddress 192.168.1.113


Corresponding MAC addresses:
snmputil walk 192.168.1.1 public .1.3.6.1.2.1.3.1.1.2.1.1
which returns:

Variable = at.atTable.atEntry.atPhysAddress.1.1.63.249.85.1
Value = String <0x00><0x10><0x67><0x00><0xd0><0x9b>

Variable = at.atTable.atEntry.atPhysAddress.1.1.192.168.1.11
Value = String <0x00><0x02><0xb3><0x1e><0x39><0xed>

Variable = at.atTable.atEntry.atPhysAddress.1.1.192.168.1.51
Value = String <0x00><0xc0><0xa8><0x7f><0xfe><0x92>

Variable = at.atTable.atEntry.atPhysAddress.1.1.192.168.1.113
Value = String <0x00><0x0f><0x66><0x14><0xe5><0x4b>
