UEFI Support?
by Bill Peck 20 Apr '10

20 Apr '10

Has anyone started working on UEFI support in cobbler? I'm guessing we would want to write UEFI configs for x86, x86_64 and ia64. They would co-exist with pxe and efi entries. Thoughts?

cobbler cli user doesn't work after 1.x to 2.0.1 upgrade
by Chris Kelly 08 Apr '10

08 Apr '10

Hello- I upgraded from 1.x to 2.0.1 and the cobbler cli user no longer works. example: [root@admin1 ~]# cobbler system add --name=foobar cobbler.cexceptions.CX:'user <DIRECT> does not have access to resource: xedit_system' [root@admin1 ~]# Looking around in the source code, I see: /usr/lib/python2.4/site-packages/cobbler/modules/authz_ownership.py def authorize(api_handle,user,resource,arg1=None,arg2=None): """ Validate a user against a resource. All users in the file are permitted by this module. """ if user == "<DIRECT>": # CLI should always be permitted return True ... so that should fall through fine. However, we are using LDAP ([authentication] module = authn_ldap) and I don't see any such code in the LDAP module. It doesn't seem that adding similar code to the authn_ldap.py file (and clearing pyo and pyc files and restarting cobblerd) does the trick. We are using the config file to manage users ([authorization] module = authz_configfile) and adding <DIRECT> as a user there doesn't let root on the command line back in. Any ideas? Thanks! -Chris

FW: [PATCH] Logging and cli error patches for master
by Vreman, Peter 04 Feb '10

04 Feb '10

I still have the patches below for cobbler. Can the patches be integrated upstream? The Koan and CLI error handling patches are real issues that break scripts and KVM virsh console support.

trac 516 - web interface repository selection in profile settings is not saved
by Gordon Child 01 Feb '10

01 Feb '10

Hello all, Fixed bug 516 from trac... I didn't see a fix anywhere out there. cpforbes originally started on this; thought I'd finish it. git://github.com/gordonchil/cobbler.git the branch it's under is 'trac516' I added this to web/cobbler_web/views.py - generic_save # Multiselect fields are handled differently if field["html_element"] == "multiselect": values=request.POST.getlist(field['name']) value=[] for single_value in values: if single_value != "<<None>>": value.insert(0,single_value)

Extending Cobbler via modules
by Kelsey Hightower 30 Jan '10

30 Jan '10

Is it possible to add new features to Cobbler entirely through a cobbler module? This seems the to be the case with DHCP and DNS management.

Saving kickstart and snippet files in WebUI uses DOS-style CR+NL
by Leonid Flaks 29 Jan '10

29 Jan '10

I ran into an issue reported in https://partner-bugzilla.redhat.com/show_bug.cgi?id=523624 The bug is reported against satellite and is somehow fixed there, but the problems seems to come from cobbler. If snippet or ks file is saved using cobbler WebUI, it becomes broken - in order to use it, one need to run dos2unix utility on it. I see it on cobbler versions 2.0.2 and master git. -- Leon

system's netboot_enabled value via api
by Gordon Child 27 Jan '10

27 Jan '10

Hello all, I'm trying to modify the netboot_enabled value on a system using the remote api. I've tried to use the modify_system function however it seems to require the actual object rather than the name of the system. This is rather expensive to serialize. (may be quick in python, but using perl's XMLRPC::Lite it takes a long time). Can modify_system be changed to take the system name rather than the system object? In the interim I've added a call that does the reverse of what already exists for kickstart files... however, this is somewhat of an issue because *anyone* can call this (and reinstall your machine) http://cobbler.example.com/cblr/svc/op/pxeon/system/cobbler-test.example.com Comments, suggestions? Thanks, Gordon Child

[PATCH] mac_address and ip_address variables
by Vladimir Zlatkin 26 Jan '10

26 Jan '10

When kickstarting systems via a profile cobbler does not expose mac_address or ip_address variables to kickstart templates. This patch fixes that. This eliminates the need to add systems into cobbler via `cobbler system add` but still allows for templates to use MAC or IP addresses as input. The use case that drove this is the following: Customer wants to have a single kickstart template for all machines (F11 in this case). The system specific kickstart data lives in an external database (LDAP). Customer would prefer to not have to register all systems to cobbler, but instead to pull kickstart data from LDAP at time of PXE. Vladimir Zlatkin Consultant Red Hat Consulting (917) 475-6797 (US)

cobbler on debian(-based) distributions
by S. Schauenburg 26 Jan '10

26 Jan '10

I tried to use cobbler with my Ubuntu machine as a host. I had to make several adjustments to the packaging/code to get it to work properly. Currently I have made them into (small) patches, which I want to submit for review, if applicable. If several small changes could be made in the cobbler source tree, the result would be that cobbler could work on even more distributions without much hassle. Therefore I have a few questions: * Is somebody currently working on getting cobbler to work on Debian(-based) and/or other distributions? If yes, who is it and how can I contact him/her/them? * Is cross-distribution functionality something that is on the wishlist? Kind regards, Sebastian

Re: post_install_network_config snippet
by Jonathan Sabo 25 Jan '10

25 Jan '10

I bet the testing you did didn't find the code path that was causing me the issue.... Check out line 165 in the post_install_network_config snippet. if [ -f "/etc/modprobe.conf" ] && [ $IFNAME ]; then grep \$IFNAME /etc/modprobe.conf | sed "s/\$IFNAME/$iname/" >> /etc/modprobe.conf.cobbler grep -v \$IFNAME /etc/modprobe.conf >> /etc/modprobe.conf.new rm -f /etc/modprobe.conf mv /etc/modprobe.conf.new /etc/modprobe.conf fi Particularly: if [ -f "/etc/modprobe.conf" ] && [ $IFNAME ]; then That needs to be escaped doesn't it? ie. if [ -f "/etc/modprobe.conf" ] && [ \$IFNAME ]; then grep \$IFNAME /etc/modprobe.conf | sed "s/\$IFNAME/$iname/" >> /etc/modprobe.conf.cobbler grep -v \$IFNAME /etc/modprobe.conf >> /etc/modprobe.conf.new rm -f /etc/modprobe.conf mv /etc/modprobe.conf.new /etc/modprobe.conf fi bf1f9105 snippets/post_install_network_config (Justin Sherrill 2009-04-09 11:27:56 -0400 165) if [ -f "/etc/modprobe.conf" ] && [ $IFNAME ]; then Is that right? I'm surprised this wasn't causing me issues before when i was testing....
