pxelocal.template and $pxe_menu_items
by Pablo Iranzo Gómez
Hi
I would like to achieve something similar to pxedefault.template but with the custom options of pxelocal.template after a system has been provisoned.
The idea is to offer the full range of profiles to each system as an aditional option.
What I did was to put $pxe_menu_items stanza on the pxelocal.template as I did with pxedefault.template, but no matter what I do, it doesn't get rendered.
After looking at the code at pxegen.py, I can see the metadata["pxe_menu_items"] in "make_actual_pxe_menu" (which outputs pxelinux.cfg/default) but not on the function referencing pxelocal.template ("write_pxe_file"), so my guess is that this is not implemented.
¿any hint?
Thanks in advance
Pablo

Doing better than I did then - I could never get this to work with my
CentOS 5.5 cobbler server - anytime I tried it cobbler came back
complaining that the resulting kickstart was corrupt/invalid. In the end
I generate the password with grub-md5-crypt and that seemed to work fine
(well, I've done about a dozen test installs since with no problems. :D
> What does the default_password_crypted field do?
As the comments in the settings file says, this field contains the
encrypted password that'll be assigned to root for your newly
provisioned systems. And the comments also warn you that if don't change
this then you'll get a warning from the 'check' command - which I
thought was a nice touch.

what happens if a snippet doesn't exist?
by Joe Linoff
Hi Folks:
I have a kickstart template step where I customize the users on each
system like this:
# default users for all systems
groupadd -g 2001 admin
useradd --gid 2001 --uid 2001 --create-dir --shell /bin/bash
--password 'sxdSJWdd/lka' admin
## Setup the individual users for this specific machine.
#set local_user_setup = 'users/' + $getVar($name)
$SNIPPET(local_user_setup)
What happens if the users/$name snippet doesn't exist?
Will the kickstart abort?
Can I do a file check to test for existence in the template?
Best regards,
Joe

koan hvm install: TypeError: coercing to Unicode: need string or buffer, NoneType found
by Gilles GAUDIN
Hi,
need help with koan when I use hvm virt type.
On cobbler server I launch following commands:
cobbler system add --name=virttest --mac=[mac address of eth0 on cobbler
server] --profile=Centos5-x86_64 --virt-type=xenfv
cobbler sync
Then on client I launch this command:
koan --server=[IP address of eth0 on cobbler server] --virt --nogfx
--system=virttest --virt-name=vm02
I can see this:

What does the default_password_crypted field do?
by Joe Linoff
Hi Folks:
I recently decided to change the cobbler password and found that the
comment from "cobbler check" didn't really help. The comment said:
2 : The default password used by the sample templates for newly
installed machines
(default_password_crypted in /etc/cobbler/settings) is still set
to 'cobbler'
and should be changed, try:
"openssl passwd -1 -salt 'random-phrase-here'
'your-password-here'" to generate new one
So I ran:
% openssl passwd -1 'testit'
<value>
and cut-n-pasted the <value> to the "default_password_crypted:" field in
/etc/cobbler/settings and updated everything:
% service cobblerd restart
% cobbler sync
Unfortunately this didn't fix anything and I still couldn't log into the
web interface with the new password. Note that I also tried using a salt
but that didn't help either. I chose no salt for my initial test because
the default entry did not use a salt.
I finally got it to work using htdigest as follows:
% htdigest /etc/cobbler/users.digest "Cobbler" cobbler
New password: testit
Re-type new password: testit
% htdigest /etc/cobbler/users.digest "Cobbler" jlinoff
Adding user jlinoff in realm Cobbler
New password: testit1
Re-type new password: testit1
What does the default_password_crypted field do?
Best regards,
Joe

Unfortunately, I'm already doing this - that's why I wanted to use
cobbler - I've got VirtualBox pretty well automated, but provisioning

That's exactly what I was looking for - I obviously need to read the
documentation more carefully in future! ;) Thanks.
Unfortunately, I've now into another problem - rather than getting my
(carefully crafted?) snippets in the output kickstart I'm getting the
SNIPPET lines instead - the system is just echoing them into the file,
rather than processing them. Anyone got some idea what (simple?) step
I've missed out on? The web interface shows "my" snippets just fine, so
I don't think it's something like protections/ownerships/etc.
And I'm very sure that if kickstart comes across a line reading
"SNIPPET('zz_netpatch')" that it's going to fail. :(
Thanks, Bob.

Snippet testing and doc updates
by Robert Cross
Two questions:
1. Is there a way to run a snippet against a system without having to
reinstall it? Reason I'm asking is because I want to generate some of
these to do various little tasks, (e.g. setup hosts, update up2date on
RHEL4), but want an easy way to test them (like I said, without having
to do an install each time).
2. If I spot areas where the documentation is less than 100%, what's the
correct way to report this - should it go to the dev list?
By the way, in closing, this is a great toolset - I can now provision my
RHEL/Centos images with the same ease as I can AIX5L with Network
Installation Manager (NIM), although Cobbler/Linux is a bit faster (just
over 5 minutes for the RHEL4-32bit VM on VirtualBox I did yesterday).
Cheers, Bob Cross.

how do i restart a VM after aborting the boot
by Joe Linoff
Hi Folks:
How do I reboot a VM after an abort?
I started the VM using this command:
dom0 # koan --virt --nogfx --system=cws12-01
There was a bad package specified in my kickstart template so I aborted
the boot and fixed the kickstart.
I then tried to restart using:
dom0 # koan --virt --nogfx --system=cws12-01
but it failed with this message:
