Re: [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! --Mike All, Can anyone point me to the best way to find the mac address of a phone on my system?? I can get the ip's just fine but dont seem to be able to pull mac addresses from any network tools. Thanks-John
