in reply to getting mac address

This is not exactly a perl question... but here is one answer.

Simple MAC queries depend upon the operating system used:
Operating systemMethod
Windows 95 and newerwinipcfg
Windows NT and neweripconfig /all
Linux and some Unixifconfig -a
Macintosh with Open TransportTCP/IP Control Panel - Info or User Mode/Advanced
Macintosh with MacTCPTCP/IP Control Panel - Ethernet icon

In addition, you can also find the MAC of all computers on your network. If using linux, the arp utility (/sbin/arp) will display cached arp requests on your machine:

$ ./arp -a ? ( at 00:06:25:E7:E8:09 [ether] on eth1 ? ( at 00:06:25:2F:69:6F [ether] on eth1

You may have to ping the machine first to ensure the information is contained in the cache.

Manufacturer Information

On a side note, the first 24 bits of the MAC identifies the device manufacturer via the Organizationally Unique Identifiers (OUI). A simple perl script can probe the IEEE database of OUI to determine the related hardware per MAC address.


You may also want to look at SNMP::BridgeQuery
