Spoofing your MAC address

Mac Address a lot of ISPs identify you by your MAC (physical) address. Here’s how to spoof it in case you want to use your connection on another computer or whatever other reason why you need to change it:

You may use the ifconfig command. Usage:

ifconfig [name of the interface] hw ether [new mac address]

so, let’s say the interface name is ” eth0 ” and you want to change your mac to ” 01:02:03:04:05:06 ” :

ifconfig eth0 hw ether 01:02:03:04:05:06

Hehe I remember spoofing my mac address because I thought Hardees (back in the day when I jacked their internet) had blocked my mac address. Good old days

rex, sorry for the late reply. OpenBSD does not let you do it by default. There is a workaround though, by using sea.c (link). Enjoy

Been using this for more than 2 yrs cuz my cable internet provider identifies my MAC and i cannot use different PC’s with the connection, they have to reset it everytime. If i wanna plug my laptop @ 1 AM.. ?
KLC is very easy to use actually.
