Hi,
I have setup Cobbler to use DHCP and the cobbler itself resides on multiple VLANs (over a Bond).
My intention is to get the ks=http://<server>/cblr/svc.. to point at the interface if of the Cobbler server for that VLAN.
When adding a system, --server-override=string can be used but I don't want this to be put on the cobbler users -- or additional code for fixing that.
My understanding is that the /etc/cobbler/dhcp.template file can be updated to provide the correct installation server. Is this correct?
Yes. Use the --dhcp-tag system parameter to assign different values to $next_server. For example, let's say you have 3 VLANs. You could assign to --dhcp_tag arbitrary values like "VLAN1", "VLAN2", and "VLAN3". Then, you could add this Cheetah markup to redefine $next_server before the :#for dhcp_tag" loop begins:
#if $dhcp_tag == "VLAN1" #set global next_server = <vlan1 IP> #else if $dhcp_tag == "VLAN2" #set global next_server = <vlan2 IP> #else if $dhcp_tag == "VLAN3" #set global next_server = <vlan3 IP> #end if
At least, I assume this should work. It all depends on whether or not Cobbler allows you to change its built-in variables.
