Folks, I am trying to use fixed IP on few Linux boxes in my LAN which uses DHCP right now.
My ISP router is configured to use DHCP and there already are quite a few laptop users who would want to continue using DHCP. However I want a set of 4-5 desktops to have a fixed IP so that I don't have to go to the machine's physical location and find its IP everytime it reboots. My ISP router's DHCP configuration does not have a bind MAC Address to fixed IP option. One of my colleagues claims that he was able to do that in a Windows 7 machine by specifying the fixed IP in network configuration. The Linux boxes are using Fedora Core 14.
Is there a way I can configure the Linux boxes to use a fixed IP everytime they boot up? I don't want to use a custom DHCP server on one of the boxes because that will be an extra point of failure for the network. Using an extra switch etc will not be favorable either, since it looks like Windows can use fixed IP without requiring that.
PS. I have tried adding a file with static IP data in /etc/sysconfig/network/ as mentioned in some internet forums, also tried "ifconfig eth0 ". This makes the IP stick but the network stops working. I guess the new version of Fedora Core could be a reason these slightly old forum posts are not providing the right direction.
