Release from DHCP server

How can I release my MAC address from a DHCP server, like "ipconfig /release" in windows? Within the leased time, I can't use another PC to get IP address as my MAC address is recorded. Would it be different on Sol or Linux?

i believe that, in linux, it is (as root): /sbin/ifconfig eth0 down replacing eth0 with whatever interface linux uses for ur network. type: /sbin/ifconfig to list all interfaces. lo is ur comp to ur comp, and is always (i think) there. it will probably be eth0

I did down the interface, but I couldn't get IP address with another machine. Any idea?

How about releasing it on the DHCP server? Alternatively set up a reservation on the DHCP server for your MAC address with an alternative IP, and then bring up the interface again. You could try faking your MAC address on the other computer to match the original one, eg: # ifconfig eth0 hw ether 00:4F:49:1D:8B:5E

I guess the DHCP server is located in ISP, I can't release my MAC add from it. Plus, I have one linux and one windows, can I use fake MAC in windows as well?

I would speak to the ISP. Here in the UK, you sometimes have to register any additional MAC addresses that you want to use, usually up to about 5 without having to pay any more.

some of the newer distro use /sbin/dhclient instead
