Bear in mind that a MAC address is something specific to an *Ethernet* network. ATM networks have their own addressing scheme and other networks will have theirs. This would only work if the person is on the same *link layer network* as you, ie, non-routed (because then you'll just get the mac of the router). The answer is to parse the output of arp -a, or equivalent... === From: Emad Fanous <Emad_Fanous@citysearch.com> Date: Wed, 21 Mar 2001 15:11:31 -0800 Subject: Re: Getting MAC address John Whitnack wrote: > > Is there a way to get a person MAC address using apache, mod_perl or > javascript.

I assume you probably want to do this to prevent spoofing of ip/server names??? === Subject: Re: Getting MAC address From: ___cliff rayman___ <cliff@genwax.com> Date: Wed, 21 Mar 2001 15:14:15 -0800 you can only get a MAC address for those machines which are on your same subnet. if you are using linux/unix try: arp sorry - but there is no reliable way to identify machines across the internet. that is why there are 'cookies'. intel tried to make this possible by embedding a number into their chips, but us privacy freaks had their heads. ===
