Static IP Question

vertigo12369 · 02-21-2008, 08:37 PM

Hello all,

I would like to set up a static IP for my server. I currently have a WRT-54GL router running DD-WRT acting as my DHCP server. Now, I can have the router set static IPs with a DHCP override, or I can update my interfaces and resolv.conf files to specify a static IP.

Which place makes the most sense? Should I update both areas?

I am running Ubuntu 7.10 server with the Xubuntu GUI.

Thanks!

I think that in the case described it is pretty much a 6 of one, half a dozen of the other situation however, traditional networking best practices would have you assign static IPs at the DHCP server as it is a single point of configuration (which matters a GREAT deal when you have more than one box) as well as remaining constant over CLIENT OS installs (which can also happen frequently in larger networks). Again, for what you describe, I believe you're safe with either one. Good luck!!

Configuring a static IP address for the interface (based on the MAC address) as you first suggested would have the advantage that the other information would be served by your DHCP server. For example, your ISP's DNS server addresses could change in the future. If you configure a samba server for WINS support, you could enter the WINS IP in the DHCP server. Your system may update your smb.conf using the /etc/samba/dhcp.conf script.
