[Asterisk-Users] finding mac addresses

[Michael Wallette]

Sure--an nmap (http://www.insecure.org) ping scan will show this. For 
example, on my network, I have an DHCP-addressed Iaxy that usually camps 
out on 192.168.1.130. Running a ping scan with nmap returns the following:

    $sudo nmap -sP -v -v 192.168.1.130
    Password:

    Starting Nmap 4.01 ( http://www.insecure.org/nmap/ ) at 2006-06-19
    12:13 AKDT
    Initiating ARP Ping Scan against 192.168.1.130 [1 port] at 12:13
    The ARP Ping Scan took 0.02s to scan 1 total hosts.
    DNS resolution of 1 IPs took 0.03s. Mode: Async [#: 3, OK: 0, NX: 1,
    DR: 0, SF: 0, TR: 1, CN: 0]
    Host 192.168.1.130 appears to be up.
    MAC Address: 00:03:64:00:15:61 (Scenix Semiconductor)
    Nmap finished: 1 IP address (1 host up) scanned in 0.758 seconds
    Raw packets sent: 1 (42B) | Rcvd: 1 (42B)
    $

While I don't yet have any VoIP phones on this network to test, I 
imagine nmap would find VoIP phones, as well.

HTH!
