dhcpd.conf is rendered from /etc/cobbler/dhcp.template - just change it there and sync. From: cobbler-bounces(a)lists.fedorahosted.org [mailto:cobbler-bounces@lists.fedorahosted.org] On Behalf Of Neal Shrader Sent: Thursday, January 26, 2012 8:08 PM To: cobbler mailing list Subject: Re: cobbler xmlrpc subnet/netmask issue Hello -- Thanks for the reply. Yes, I saw that it was renamed, and I'm able to properly manipulate netmask-eth0. The only problem is when running a cobbler sync, /etc/dhcpd.conf is regenerated with the deprecated subnet value instead of the value I set for netmask-eth0. Here's the revelant stanza that's produced by cobbler sync from the host I was working with in the original email. host <redacted> { hardware ethernet 78:2b:cb:1e:a0:3d; fixed-address 69.55.48.164; option subnet-mask 255.255.255.224; option routers 69.55.48.129; default-lease-time 21600; max-lease-time 43200; filename "/pxelinux.0"; next-server 10.15.254.5; } 255.255.255.224 = subnet value, 255.255.255.128 = netmask-eth0 value. This causes PXE boots to fail when we need to modify our subnet mask. If netmask-eth0 was used, we'd be in good shape. Is there a way to remove or modify the deprecated subnet field, or a way for dhcpd.conf to use the expected netmask-eth0 value? -Neal On Thu, Jan 26, 2012 at 4:28 PM, Michael DeHaan <michael.dehaan@gmail.com<mailto:michael.dehaan@gmail.com>> wrote: This was renamed to net mask in a previous version of the app. Looking at the code (item_system.py) if not self.interfaces.has_key(name): self.interfaces[name] = { "mac_address" : "", "mtu" : "", "ip_address" : "", "dhcp_tag" : "", "subnet" : "", # deprecated "netmask" : "", The net mask line needs to be deleted here -- we shouldn't be adding the old field back when making new objects. 5000 imaginary Cobbler points if someone would like to remove it and test that everything's still cool. --Michael On Thursday, January 26, 2012 at 4:21 PM, Neal Shrader wrote: Hello -- I've got a little problem regarding cobbler system netmasks, and interfacing with them through xmlrpc API.
