disabling second nic and HP firmware cd...

[Corey Kovacs]

Folks,

Is there a built in 'correct' way to ensure that my second nics are
not configured during build and left alone when using the network
config snippets delivered with cobbler?

RIght now, when the nodes finish building, the undefined second nic
tries to dhcp even though I've not given it a config.

I am getting around this by making the appropriate changes to
ifcfg-eth1 via two 'sed' lines but if there is a 'better' way I'd
rather do that than rely on a post config.

Also,

are people using the livecd boot method for booting HP firmware disks?
How about the SSTK?

Thanks

You can do it in the bios.  Yes STK would be a solution to handle that.

We added the following to the post_install_network_config snippet so any
non-defined interfaces will get ONBOOT=no in their configuration file.
Right before the "rm -f /etc/sysconfig/network-scripts/ifcfg-*" line.
It may not be what you are looking for (not built-in) because you have to
modify an upstream provided snippet.

I just pushed the commit to github, so you can also take it from there:
https://github.com/chutzimir/cobbler/compare/leave-interfaces-down

#raw
cd /etc/sysconfig/network-scripts
for iface in ifcfg-*; do
    [ -f cobbler/$iface ] && continue
    grep ^DEVICE $iface   >  cobbler/$iface
    grep ^HWADDR $iface   >> cobbler/$iface
    echo "ONBOOT=no"      >> cobbler/$iface
    echo "BOOTPROTO=none" >> cobbler/$iface
done
#end raw

But if you are looking for a built-in way you can maybe actually define
the NIC in cobbler with a static IP of 127.1.1.1 (or similar)?
