Re: OMAPI support for ISC DHCPd must die
by Robert Lazzurs 24 Nov '08

24 Nov '08

Hello, First of all +1 on this as these are changes I need :) Now as for the restart/reload. From what I remember ISC DHCPD requires a restart to notice any changes in the config file, HUP does not do the job. However I would suggest this is not a major issue as anyone depending on DHCPD should be running at least 2 servers. Also DHCP clients should be requesting a new lease way before the lease time expires and most do. Just my thoughts, take care. -- Rob Lazzurs On 23 Nov 2008, 9:15 AM, "Jeroen van Meeuwen" <kanarip(a)kanarip.com> wrote: -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Michael DeHaan wrote: | Two things: | | (A) It's been pointed out to me the OMAPI support in cobbl... +1 Additionally, OMAPI does not do the trick when dhcp.template has been altered and you do a cobbler sync (thus dhcpd.conf has been altered); the dhcpd service will have to be reloaded or restarted. | The only limitations I really see is that there is a window when doing | the sync when the servic...

OMAPI support for ISC DHCPd must die
by Michael DeHaan 23 Nov '08

23 Nov '08

Two things: (A) It's been pointed out to me the OMAPI support in cobbler results in permanently deleting leases in nasty ways when "cobbler sync" is run or systems are edited. (B) I've been told dhcpd support of OMAPI is slated for removal in a future version of ISC dhcpd. Cobbler's DHCP management is much more solid with OMAPI disabled, and based on comments I've gotten on it, I propose we remove the feature for 1.4. It just does not feel particularly robust, and the feature seems to be going away anyhow. Comments welcome. The only downside to removing OMAPI is that to apply new MAC -> IP reservations (or in turn, MAC -> IP -> Hostname) DNS setups (if so enabled), it would require a "cobbler sync" once again. We could potentially add options to cobbler sync to just refresh DHCP/DNS without doing other sync activity if that helps with speed. The only limitations I really see is that there is a window when doing the sync when the service restarts, but that would only affect machines rebooting at that particular point in time. Sounds good? --Michael

Installing Fedora9 using Cobbler
by Denise.Agosti＠dana.com 21 Nov '08

21 Nov '08

Hi, I have been successfully using Cobbler to install Redhat 4.5 and 5.2 using the following line in my kickstarts: url --url=$tree I am now trying to use Cobbler and that same url line in the kickstart to install Fedora9 but I am getting the following error: Kickstart Error Unknown Url method $tree I have also tried using the following line (where 10.10.10.10 is replaced with the valid IP for my Cobbler server) url --url=http://10.10.10.10/redhat/cobbler/ks_mirror/FEDORA9 which is where the images directory is located but it errors too as follows... Unable to retrieve http://10.10.10.10/redhat/FEDORA9/images/stage2.img Could anyone please help me determine what is the correct URL line to place in my kickstart for Cobbler to be able to install Fedora9? Your help is much appreciated.

gateway and hostnames with multiple NICs
by Vreman, Peter 20 Nov '08

20 Nov '08

I've systems with multiple NICs. This gives problems with the gateway and hostname that are configured per NIC. My proposal is: - Make the Hostname and Gateway a system wide field instead of per NIC. This information can be used to generate the /etc/sysconfig/network - Add an optional dnsname field to the NIC that can be used to provision the DNS or generate a hosts files - Add a route field to the NICs there entries can be added in the format ipaddress:netmask:gateway. This is used to generate route-ethX Any toughts? Regards, Peter This e-mail and any attachment is for authorised use by the intended recipient(s) only.

1.3 Documentation review and comments?
by Michael DeHaan 20 Nov '08

20 Nov '08

One of my ongoing concerns is whether the documentation available to Cobbler makes sense, is easy to read, and folks can find out the questions they want to know. I think over the past several months we've built up a large amount of docs on the Wiki and made that a primary source for information. That all being said, I'm not the best to evaluate it because of preconceptions about what it already says :) What probably hasn't gotten the most attention is the manpage -- Since we've reordered the fields and added lots of new features, recently, I've made some edits to the manpage, and think it would be a good time for those that depend on it to review things to see if they make sense (particularly, if you can, pretend you were reading things for the first time). To save you the trouble of building the manpage, anyone with Perl installed (read: everyone) can do: wget "http://git.fedorahosted.org/git/cobbler?p=cobbler;a=blob_plain;f=docs/cobbl…" -O output.pod perldoc output.pod I would also be interested in comments about the Wiki documentation, stumbling blocks you encountered when learning what cobbler does, or problems your coworkers might have encountered when you showed it to them for the first time. One thing I note, in particular, is it still makes some references to Fedora Core 6 which should most definitely be replaced with F9 :) Comments welcome. --Michael

(devel) Some more candidate patches
by Javier Palacios 20 Nov '08

20 Nov '08

action_import.py patches to be examined. The first two made simpler the way that version & kickstart are found http://github.com/javiplx/cobbler/commit/dbc5af528938fd44feee219574d2190525… http://github.com/javiplx/cobbler/commit/dbc0013d12bf216b9c80e61d2d5c43686e… The third one extends the search for version specific kickstarts into debian/ubuntu http://github.com/javiplx/cobbler/commit/8b57ab14f71dd5f969855da3e634e608bf… Javier Palacios

[Patch] etc cleanup
by Vreman, Peter 20 Nov '08

20 Nov '08

Please find the patch that installs the pxe,power in /etc/cobbler/(pxe|power)/ and the kickstarts in /var/lib/cobbler/kickstarts. The rpm.spec has been updated to move pxe and power files. Existing *.ks files are copied to the new location to not break existing references from profiles.

Re: [PATCH] PPC is strange. RHEL provides a 'ppc' tree that is intended only for ppc64 systems (typically IBM PowerPC). Fedora provides a 'ppc' tree that includes ppc32 and ppc64 kernels. Fedora also builds a 'ppc64' tree which contains *only* ppc64

Any cobbler imports on a ppc tree will detect and add the appropriate distro's and profiles for the ppc32 or ppc64 if applicable.

There are two sets of files matching *release-*, and in any case you probably need to add something to codes.py. I cannot do anything with RedHat, but I will try the fedora9/rawhide. It looks that there is something now working well in the import code, and I wanted to check a debian powerpc import in any case. Javier Palacios

default profile
by Vreman, Peter 20 Nov '08

20 Nov '08

Is it possible to add a default/no-profile profile? When this profile is selected the default menu will be shown. This allows the following use cases: - Default PXE for unknown MACs will be autodiscovery - Autodiscovered systems can have this default profile (current pxelinux.cfg/default) assigned - Additional safety that prevents accidently redeploy of a system. After deploy the system can be assigned the default profile. You must change both the netboot and the profile before a system is redeployed after a reboot. Thoughts?
