as long as they are in the same network segment as the asterisk server you can use arp man arp mojowrkn wrote:> All, Can anyone point me to the best way to find the mac address of a > phone on my system??

You may need to ping the phone beforehand to make sure its address is actually in the table. If the phone is not in your LAN, there is no direct way to tell. -- Tzafrir Cohen sip:tzafrir@local.xorcom.com icq#16849755 iax:tzafrir@local.xorcom.com +972-50-7952406 tzafrir.cohen@xorcom.com http://www.xorcom.com

[Asterisk-Users] finding mac addresses
an example might be
IP="10.0.0.213"
MAC=`arp | grep "$IP" | awk {'print $3'}`

If your phones are connected to a Cisco switch, depending your your IOS level you can possibly use the "show mac-address-table" command. Which would show you not only the mac-address for all the devices attached to the switch, but what port they are hanging off of. Hope this helps.

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:

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!

If it doesn't show up, ping it first to populate the arp table. Out of curiosity, for what purpose do you need the MAC address? James
