I would like to determine what computers are currently connected to my access point/router via the command line in Linux.

How can I do this?

You can also try:

arp-scan [network/CIDR] eg: arp-scan 192.168.1.0/24

You may need to install arp-scan - most major distributions have it in their repos.

nmap -A -T4 'ip of your network'

well just to make sure I did ifconfig to ifconfigfind my network ip and it returned inet addr as 192.168.1.101 so I then did nmap -A -T4 192.168.1.101 and got this back Starting Nmap 5.00 ( nmap.org ) at 2011-02-12 16:48 CET Note: Host seems down. If it is really up, but blocking our ping probes, try -PN Nmap done: 1 IP address (0 hosts up) scanned in 2.09 seconds –  classer Feb 12 '11 at 15:49
