Actually I worked around that and I made a configuration which is probably
wrong,

Re: manage dhcp with cobbler

Harry Hoffman — 2013-06-18T13:02:23

Hi Leo,

Sure, you can.

Check out the template file /etc/cobbler/dhcp.template.

Define the subnets you are using above the line that starts:
#for dhcp_tag in $dhcp_tags.keys():

Then tell cobbler to manage dhcpd by setting manage_dhcp: 1  in
/etc/cobbler/settings.

Restart cobblerd and run cobbler sync. The dhcp.template will be
expanded to /etc/dhcp.conf on redhat > 6 and /etc/dhcp/dhcpd.conf on
redhat =< 6

Cheers,
Harry

manage dhcp with cobbler

leo loe — 2013-06-18T12:21:44

Hi,

I am newbie on cobblerd. I am curious if I can manage dhclient.conf with
cobbler. I got many subnets in my network. For example I got a management
network and project subnet. So my servers have at least two interfaces. Can
i use cobbler to use for giving IP addresses both of those interfaces. So
that

eth0: x.x.x.x
eth1: y:y:y:y

and I can manage to that via dhclient.conf by using user-class option. But
I don't know how to do this via cobbler by using dhcp_tag. Any ideas?

Regards

cobbler menus broken

Mark Sallee — 2013-06-14T18:50:11

Hi,
I have a RHEL6 system that will not add new systems to the PXE boot
menu. When I attempt to select any of the choices on the menu (local
boot, rhel-6.4, or memtest), none can be selected, and the timer gets
reset for another 20 seconds.
- If I wait until the timer is done, it attempts a default local boot,
which lets me know there is no OS installed yet and stops.
- Tried changing the default menu boot choice to rhel-6.4-x86_64, it
does not work either.
- This problem only began after a recent rebuild of the kickstart server
with the latest version of cobbler.
-cobbler.log shows a lot of this:
Fri Jun 14 16:51:45 2013 - DEBUG | REMOTE expiring token; user(<DIRECT>)
Fri Jun 14 16:51:45 2013 - DEBUG | REMOTE expiring token; user(<DIRECT>)


Strangely, if I already have an OS on the system, "koan --replace-self"
does successfully PXEboot the system, bypassing the menu.

cobbler version: 2.2.3-2.el6.
OS: RHEL 6.4 x86_64
hardware: Dell M610 blade

Multiple Subnets Dhcp

leo loe — 2013-06-14T17:13:29

Hi,

I am newbie on cobbler. I want cobbler to handle multiple dhcp subnets with
using dhcp_tag. In other words, I got two subnets one for management and
the other for cobbler, so when I creating a new system I define two
interfaces eth0 and eth1 with mac addresses. dhcp_tags values are PXEclient
and management. However I cannot handle the dhcp side of the system. Do you
have any idea?

Regads,

Lutphi

Re: ESXi 5.1 Build Fails

Jose Cardoso — 2013-06-06T09:25:35

What is the exact error you are getting and where? You may also want to supply a copy of the output to:

cobbler distro report --name="ESXi-51"

I'm currently using the most recent 2.4.0-beta6 release from GitHub with no problems with regards ESXi 5.0 U1/U2 or 5.1 U1 booting (ignoring the missing template value from a cobbler import which James has already mentioned he is fixing).

yes, --nobase is what i'm installing.

supplying 'wget' in %packages fixes.

That is entirely possible if you're doing a kickstart with --nobase or
removing extra packages.

no sign of 'nopxe'

might wget be missing?

i can add to %packages and try again.

When viewing the rendered kickstart, can you verify whether you see this
line?

wget "http://<server>/cblr/svc/op/nopxe/system/<name>" -O /dev/null

If so, can you verify that you see that request in your httpd logs?

Could I get some help understanding and fixing pxe_just_once?

[david< at >ops-1 ~]$ grep pxe_just /etc/cobbler/settings
pxe_just_once: 1


I've restarted cobbler. The system I've installed has been looping on pxe
for a few installs while I've tried a few things.

I've added:
%pre
$SNIPPET('kickstart_start')
%end

%post
$SNIPPET('kickstart_done')
%end

to the kickstart; tailing Apache logs confirms that the wget is being
called, yet the netboot setting remains to be True:
Netboot Enabled                : True

Am I missing a trigger that I'm supposed to supply?

Re: help with moving a cobbler server

David Birdsong — 2013-06-05T18:18:58

that was it. i found "cobbler list" which is a great summary and now see
that the distro didn't carry over due to the source file path not being
valid.

i re-added the distro to match the same name and restarted cobbler and see
the profile list now.

thanks!

I updated the TFTP Boot Files for the distro to: $local_img_path/*.*=/var/www/cobbler/ks_mirror/ESXi-51/*.*. I also added the template file to the distro: /etc/cobbler/pxe/bootcfg_profile_esxi51.template=$local_img_path/cobbler-boot.cfg.

I ran cobbler sync as well.

I'm still having the same problem and same error when trying to build the hypervisor.

I plan to have this automated in the official 2.4.0 release, so this step
will not need to be done manually in the future.

Re: help with moving a cobbler server

James Cammarata — 2013-06-05T11:55:59

I don't believe there should be any version issues in that move.

When profiles don't show up, it typically means that one of the required
fields is not there. In the case of profiles, that means the parent
distribution is missing. Are the distros loading and showing up when listed?
