Hi,
We have a provisioning server with 5 interfaces on different vlans. We
are running 2.6.11 but the solution we have may still be relevant to
2.6.5.
The bit in the dhcp template that is relevant is the host loop at the
bottom
you need to uncomment the iface.nextserver bit
## Cobbler defaults to $next_server, but some users
## may like to use $iface.system.server for proxied setups
next-server $iface.next_server;
Also, you will need to generate a new profile for the new next_server
and set a dhcp tag and a server override. I think the tag name can be
anything, the server override needs to point at the new next_server.
The documentation on this is seriously lacking. I just took a guess that
the iface.next_server will be filled in by the server override. It works
for us but it's all very poorly documented and explained on the web and
in the man pages.
Regards,
Emyr
