Remote mac address

[Matias Surdi]

Anyone knows how having the IP address of a host on the lan could I get
the mac address of that hosr?


p/d: Parsing the output of arp -a is not an option.

Thanks a lot!

But the ARP table is exactly what you need to access. This is probably
system-specific.

You could also try to send ARP requests yourself:

Any reason why arp is not an option?

What kind of system?

On linux and probably several other unix-like systems you could (if
you had permission) parse the /proc/net/arp file. Granted this isn't
terribly far off from parsing the output of 'arp -a', but at least
it keeps you from spawning a shell to run the 'arp -a' in.
