Does anyone know the details of how MacOS X manages "Using DHCP with manual IP address?" The real reason I'd like to know is that my Mac OS X machine works fine on the network at work, maintaining the IP address I set and not causing any conflicts. But I can't get the Linux box I've set up as a development server to do the same thing.

The man pages for linux dhcpcd seem pretty clear, but the -s and -h flags cause it to fail to get a lease at all, and without them I get a different IP address on every reboot.

I'd ask the network administrators here, but both Mac OS X and Linux are "unsupported." I'd sure appreciate any ideas you guys have.

Well, you have to figure out the MAC address (simply do an ifconfig en0 and look for ether; it looks something like this: 00:02:33:d9:88:aa).

Then you have to edit the DHCP config file (dhcpd.conf), add an entry for your system

host myOSXbox {
hardware ethernet 00:02:33:d9:88:aa;
fixed-address 192.168.1.222;
}

in the proper subnet.

Check out the HowTo. I have successfully set this up on my FreeBSD box.
