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.

Hello --
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:

>>> import xmlrpclib
>>> cobserver = xmlrpclib.Server("http://127.0.0.1/cobbler_api")

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
>>>
>>> cobserver.get_system('1301')

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!
