Depending on the DHCP server, it may use the MAC plus some other (UID) information when assigning leases. I found that with dual-booting, I did get different IPs unless I hard configured my DHCP server to assign IPs to specific MACs. The default automatic configuration saw Linux just assigned by MAC; and Windows supplying MAC, plus something else, got a different IP. e.g. The last line in this /var/libs/dhcp/dhcpd.leases stanza (on the DHCP server) is present in Windows clients leases, but absent with Linux clients. lease 192.168.1.197 { starts 5 2008/08/22 11:36:29; ends 1 2008/08/25 14:20:43; tstp 1 2008/08/25 14:20:43; binding state free; hardware ethernet 00:1b:77:0a:65:e4; uid "\001\000\033w\012e\344"; } > > Also, I don't know of any DHCP server that makes use of the supplied > host name to make its reservation decisions. Me either, but I think you could probably use scripts with your own server, or perhaps just some configuration, to make that kind of use of it if you wanted. I've seen servers use the supplied name in the current leases (e.g. on routers showing the currently connected machines) and adding those hostnames to local DNS servers (when they integrate DHCP and DNS serving). The client can ask for it and keep it, but I've not noticed it being a part of lease reservation. -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
