(for instance ability to read the IP of the host).
Are you using tagged vlans? Personally, I would not set cobbler up that way, as it becomes a maintenance headache. If you're using Cisco hardware, you can configure your switches to use the "ip helper" command to forward layer 2 traffic to a layer 3 host, so you can do things like DHCP and PXE across segments. In your case, if you're using tagged vlans, you'll have to create a vlan interface for every vlan you want to build things on, and configure dhcpd networks for each of them in dhcpd.template (also add the vlan interface to your dhcpd settings, /etc/sysconfig/dhcpd if you're using RHEL or similar). Then you can use the dhcp tags variable to pin systems to a specific dhcp network. The down side is, everytime you add a new network, you have to update your dhcpd.template, settings, etc., thus the maintenance headache. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. _______________________________________________ cobbler mailing list [email protected] https://fedorahosted.org/mailman/listinfo/cobbler
