[BlueOnyx:01953] IP Addressing on sites

[Chuck Tetlow]

Hi BlueOnyx experts.  Maybe one of you know a resolution to a IP Addressing problem.

One of the companies has a bunch of BlueQuartz servers that they've got me converting to BlueOnyx.  But BlueOnyx has the IP addressing issue BlueQuartz had.  Specifically, whatever IP address you put on the box (eth0) - it copies that same netmask to the IPs for the sites.

Since this company wants to keep all the "box" addresses in a similar network, they have a /28 network for their virtual servers.  Then they assign a class-C  /24 block to the sites on each server.  The problem is the BlueOnyx keeps the same /28 subnet mask on the subinterfaces for the sites.  And that means that we loose the ability to use two IPs out of every 16 (its considering one of them a network identifier and one a broadcast).

So, what I'm looking for is a way to set the netmask on the subinterfaces for the sites.  In the past, I've spent a lot of time going through each ifcfg-eth0:xx with VI correcting the mask and broadcast IPs.  Then to prevent the system modifing those interfaces again the next time a site was added - I had to set the immutable bit on them.  Which of course means that I'm the only one that can delete a site - because I have to turn that off first.  Not a good fix.  But I don't know any other method.

Does anyone know how to change the netmask and broadcast on all the subinterfaces - and get the management GUI to use something other than what is assigned to eth0 (when creating new sites)??

Chuck
