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'

I use arp -an
mybox $ arp -an
? (172.16.17.135) à f0:1f:af:36:93:fa [ether] sur wlan1
? (172.16.17.143) à f8:16:54:95:ac:b2 [ether] sur wlan1
? (172.16.17.65) à 8c:70:5a:a4:74:a8 [ether] sur wlan1
? (172.16.17.1) à 00:1C:d4:01:06:0c [ether] sur wlan1
If you feel adventurous, you can use arp -a
which will try to resolv IP.
This will show you only local host with active connection.
Edit:
arp
is somehow deprecated, now you sould use ip n
(n as neighbour).
IMHO, the -a
non-tabular output format is less lucid than without -a

Depending on Linux version and also on network configuration you need to supply network information for arp-scan
so it knows what to scan as you may have (and usually you do) multiple interfaces.
I'd recommend this command options
sudo arp-scan --localnet --interface=en1
First of all, you may need sudo
because arp-scan
uses some services that require root privileges.
--localnet
frees you from having to know your IP and it will scan 256 addresses like 192.168.1.0/24
but will handle address for you automagically.
--interface=en1
is the interface it will use in case default en0
is not your active link. To check which interface is active along with other useful information use
ifconfig
If you are using Mac OS X, you will need to install package. To do so, visit Rudix repository, download and install package (you will need administrative privileges and password) and then use like I suggested.
well just to make sure I did
– classer – 2011-02-12T15:49:10.630ifconfig
to ifconfigfind my network ip and it returned inet addr as 192.168.1.101 so I then didnmap -A -T4 192.168.1.101
and got this back Starting Nmap 5.00 ( http://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
