That's all templated out, check /etc/cobbler and you should find a template that references the old value, and probably a ".rpmnew" version that does not, that needed to replace the old one.

Make sure you preserve any edits you might have made to the original template.

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.

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:

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!
