Yep. See Status -> Local Network
<http://www.linksysdata.com/ui/WRT54GX/v2/2.00.09/Status-Local%20Network.htm>
and hit the "DHCP client table" listing.
The problem with this is that it does not show:
1. Addresses that the user has assigned themselves (static IP's).
2. If the router was rebooted, addresses that are still in use, but
have not yet renewed their DHCP leases.
3. Additional addresses that have been mnaually assigned to a single
MAC address.
If you want to find out what addresses are actually in use, I suggest
you use a utility to scan all 254 available IP's and see if they're in
use. This is an example of a crude but fast ping scan:
C:\Nmap> nmap -T3 -sP 192.168.1.0/24
Starting Nmap 4.20 (
http://insecure.org ) at 2007-09-01 09:28
Pacific Daylight Time
Host 192.168.1.1 appears to be up.
MAC Address: 00:14:BF:B9:10:13 (Cisco-Linksys)
Host 192.168.1.11 appears to be up.
Host 192.168.1.50 appears to be up.
MAC Address: 00:40:05:C7:1C:44 (ANI Communications)
Host 192.168.1.51 appears to be up.
MAC Address: 00:C0:A8:7F:FE:92 (GVC)
Nmap finished: 256 IP addresses (4 hosts up) scanned in 14.101
seconds
Hmmm.... missed a few devices that are set to delay pings and probes.
Also, if you have a mess of Windoze boxes, some with open shares, try
NBTSCAN from:
