I've been trying ifconfig but I can't seem to get it to work.
My cable provider registers MAC address and I switch back and forth between two machines. I don't want to use a router. Any help would be appreciated.

Anyone know how to change the MAC Address on the ethernet card?

out of luck..
As far as I know.. MAC addresses can't be changed. They are hard coded into the NIC

Actually, some guys came up with a way to do this, but it only runs on OS 8 - 9.0.4:

What MAC addresses are for
The whole idea of a MAC address is so that each and every network card in the world can be positively identified. The ability to change your MAC address would defeat this purpose, and create a possibility for hardware address conflicts, which would be almost impossible to find and correct on large networks. The MAC address is hard-coded into most network cards.
Actually...
The purpose of a Mac address isn't so that all ethernet cards can be positively identified. Mac addresses are different so that communication over the IP layer is possible. Mac addresses can be the same (though, unless you are manually changing them, this will never happen) they just can't be the same on the same LAN.
Re:Actually...
You seem to have misunderstood what I meant. I meant that a MAC address is supposed to be unique, so that even if you created a LAN containing every network card in the universe, they would all have a different MAC address, and therefore be individually distinguishable. If two had the same MAC address, the messages destined for either of them would be received by both, and messages from either of them would appear to be coming from a single card. This is why each and every network card manufactured has a MAC address hard-coded into it.
reset cable modem
to use more than one comp with ur cable-modem
One option is an Airport basestation
You can use an Airport Base Station to share a cable-modem, not to mention wireless networking of your computers. Not the cheapest option, certainly, but If you happen to have a portable or plan to get one (how 'bout that new iBook?) you will be loving life if you get a base station. I recently got an (older) iBook and tried out an airport base station and card with it at home (for me, just over a dial-up connection.) It is, to say the least, extremely nice. It would be even better with a cable-modem. It was painful to have to take the base station back to work. :( Eventually I'll get my own for home. Yes, it works great with OS X, however, to set it up you will want to boot into OS 9. There are some 3rd party tools to do it on X, but Apple's OS 9 tools are much easier to use.
Contact your provider
I don't know about your cable provider, but I can contact mine and give them a number of MAC addresses should I wish to use more than one computer!
One option is an Airport basestation
I can confirm that an Airport base station will route with AT&T @home cable as well as with PacBell DSL.
Not if your ISP doesn't allow routers
One of the reasons MAC addresses exist is to allow network verification. Some ISPs don't want you sharing your high speed access with everyone else in your dorm (what a shocker) or entire apartmet building, so they won't allow routers on their network. The Airport base station is a router. If you have such an ISP, then an Airport base station wont help you. Your ISP simply won't let the Airport base station on the network, since it's not the MAC of one of the network cards they've approved (when you sign up, or add a new computer by calling their tech support).
you could use gNAT
you can use gNAT to setup software network address translation within osX which would alow you to share the connection between the two machines. i think gNAT is available form the apple osx software download area. if not, try versiontracker.com
mac address
You can solve this problem with Asante's friendlynet cable router.
Change the MAC address
I have been looking for this answer for quite some time and have finally found it. It is complicated but can be done.
Change the MAC address
I found that place as well and as far as the instructions given everything went well (recompiled xnu and everything). Only I still don't know howto change the mac address since I can't get nemesis to compile (actually can't install netlib) and ettercap is a strange beast which doesn't seem to want to change anything for my system. I read something on apple.com (development section) about an enchanced version of ifconfig. The current one really sucks I tell you. Bah, damn BSDs... |
