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?

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.

I've got a little problem regarding cobbler system netmasks, and
interfacing with them through xmlrpc API. I'm using a system that was
recently upgraded to cobbler 2.3.1. From what I can tell, the subnet field
was deprecated, but I still seem to be getting it in my output, and it's
affecting our cobbler syncs. To state it explicitly:

Note in the above I have a netmask = 255.255.255.128 which is associated
with the interface (eth0). I also seem to have a "subnet" value which is
set to 255.255.255.224. I can modify the interface netmask fine:
===
>>> token = cobserver.login(USERNAME,PASSWORD)
>>> handle = cobserver.get_system_handle('1301',token)
>>>
>>> cobserver.modify_system(handle, 'modify_interface', {
"netmask-eth0" :
"255.255.255.252" }, token )
True

However that other subnet value, I don't seem to have a way to edit or
remove that I'm aware of.
The problem with this is when I attempt to cobbler sync, dhcpd.conf is
updated with that global subnet value instead of the netmask value that I
set myself. How do I remove or edit the incorrect subnet value? Am I
doing something wrong, or is this a bug?
Thank you for looking!
