Hi Clint thanks for reply. let me explan in detail. I think we need use snippets sovle the problem. I use cobbler deploy OS. I hope all the pc have static IP. I try to cobbler system add --name=node58 --profile=CentOS6.2-x86_64 --mac=00:25:90:2D:7A:42 --interface=eth0 --ip=172.16.10.58 --hostname=node58 --gateway=172.16.10.1 --dns-name=114.114.114.114 the node would static IP , This is exactly what I wanted. for Redhat, cobbler provide <a href="https://github.com/cobbler/cobbler/wiki/Kickstart%20Snippets">Kickstart Snippets</a> for seting static IP address. <a href="https://github.com/cobbler/cobbler/tree/master/snippets">https://github.com/cobbler/cobbler/tree/master/snippets</a> but for ubuntu, modify IP have different from Redhat. How to let ubuntu also can set static IP use Snippets. <div class="gmail_quote">On Wed, May 9, 2012 at 10:25 PM, Clint Byrum <<a href="mailto:clint@ubuntu.com" target="_blank">clint@ubuntu.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Excerpts from Shake Chen's message of Wed May 09 05:47:11 -0700 2012: <div><div class="h5">> Hi > > I have set up orchestra in ubuntu 12.04. use cobbler deploy OS > > the Centos and ubuntu working well . > > Now I need set the static IP address for the node. > > In centos , I have success, > > but for Ubuntu, it no working. > > I read <a href="http://terrarum.net/administration/deploying-ubuntu-with-cobbler.html" target="_blank">http://terrarum.net/administration/deploying-ubuntu-with-cobbler.html</a> > > can not working. > </div></div>Hi Shake! If you want to set the IP address in the pre-seed, edit the kickstart template and add a section with static IP config: # Static network configuration. d-i netcfg/get_nameservers string 192.168.1.1 d-i netcfg/get_ipaddress string 192.168.1.42 d-i netcfg/get_netmask string 255.255.255.0 d-i netcfg/get_gateway string 192.168.1.1 d-i netcfg/confirm_static boolean true You can replace any of these with variables, check sudo cobbler system dumpvars --name=your-system-record To get the values for the system you want to boot. <div class="HOEnZb"><div class="h5"> -- ubuntu-server mailing list <a href="mailto:ubuntu-server@lists.ubuntu.com">ubuntu-server@lists.ubuntu.com</a> <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-server" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-server</a> More info: <a href="https://wiki.ubuntu.com/ServerTeam" target="_blank">https://wiki.ubuntu.com/ServerTeam</a> </div></div></blockquote></div> -- Shake Chen
