Translation -- does anyone want it?
by Michael DeHaan 12 Nov '08

12 Nov '08

Removing the translation hooks in Cobbler would clean up the code a bit and there are places where they are not consistent. Does anyone object to removing translation from Cobbler? This does not preclude some day having a translated webapp, but the rest of the messages would not be. I think Cobbler moves a bit too fast to keep translations up to date and accurate, and I don't plan on slowing down :) Higher level apps like Spacewalk/Satellite are of course translated, and I imagine ovirt will be translated. --Michael

Allow for COBBLER_SERVER environment variable
by James Laska 12 Nov '08

12 Nov '08

SNAKE writes out /etc/profile.d/snake.sh after each install to point back to the snake-server used by the client. I'd like to extend this for my cobbler kickstarts. A quick fix on the koan side would set the default --server value to the environment variable COBBLER_SERVER. Thoughts? Thanks, James

API Patches for underscores and dashes
by Bryan Kearney 12 Nov '08

This is a resend of patches from yesterday. It enhances the API to suppport underscores and dashes. It also adds some attributes to the image object in teh ruby bindings

Ruby API Patch
by Bryan Kearney 12 Nov '08

12 Nov '08

The API for cobblet takes in attribute with hyphens (e.g. virt-cpus) but returns them with underscores (virt_cpus). This patch sends the attributes for images and systems with _ not -.

Access to profiles in "multi-org" hosting context
by Michael DeHaan 12 Nov '08

12 Nov '08

Cobbler has several access control features designed for various purposes, there's the ownership module, the new per-field ACL feature on top of that (not really enforced by the webapp yet... TBD), the pluggable authorization modes, and fields such as "server-override" and "dhcptag" for making sure machines show up with the correct DHCP and Cobbler server addresses. There are also tools such as replication to help deal with multiple cobbler servers. So far this has mostly been sufficient, but a use case came up today that is not completely aligned with the above that I wanted to bring up here. Today in a meeting with some of the Spacewalk developers they brought up a rather interesting use case. Historically Spacewalk has had essentially random temporary kickstart URLs and has not had a tool like koan that allows for browsing the remote profiles. This seems to be a security feature, and it kind of is, but it's not especially robust --- TFTP and DHCP are wide open protocols and this information is freely obtainable and easily sniffable depending on network setups. What they want however, is largely a shoot-foot-prevention feature that would fit a scenario something like this. A Cobbler server is used to manage a hosting company -- not something that is chrooted per se, but something closer to gogrid, slicehost, EC 2, or another that gives full root access. How do we prevent someone from installing profiles that are assigned to another organization, therefore using their kickstart URLs, and those kickstart URLs contain The most secure answer is to create a seperate cobbler server that each org can access (possibly running virtualized), pointing to a master server that they all get distro content from. However, in the Spacewalk case this is not possible to install in all situations. What they want is essentially a way for --list-profiles, --list-systems, and --list-images in koan to not show all the images, but only which ones are in the current "organization". For example: koan --server=cobbler.example.org --list-profiles # shows profiles that don't have the organization set. koan --server=cobbler.example.org --org=acmecorp # shows profiles that have the field organization set to acmecorp The above would be required because there is no way to tell from an existing Spacewalk node what organization it is part of, and we don't want to require cobbler to pass credentials back when using koan -- it makes koan /much/ less usable to do this. Does anyone else find this idea useful or have ideas on implementation, or have similar concerns? Does anyone run anything similar to this current use case now and might want to share what they do to ensure one company doesn't use another's kickstarts? All profiles would still be readable via the API, but their wish is to see this filtered out from the user to avoid shoot-foot scenarios. The only problem is that this is adding yet-another-field to cobbler and that adds complexity for the user when trying to understand the application. The other solution I have suggested is that instead we increase the strength of the multi-org support within Spacewalk, so that if they attempt to call rhn_register to an organization where the physical machine is not part of that organization, this can be blocked. This would be something that would not be set up by default. Does this make sense? Kind of? Another option might be for Spacewalk to use koan as a library, and write their own client code around it for the multi-org feature. For those that can see a use for this in Cobbler core and have similar setups, what would you like to see? --Michael

It can be seen at http://github.com/javiplx/cobbler-debian/commit/36ca9d05e7b75cf2c1550067ada… It moves into process_comps_file method a member variable which is not used elsewhere. Javier Palacios

Image creation patches
by Bryan Kearney 11 Nov '08

11 Nov '08

Two patches for image creation. The first one modifies cobbler to add a "network_count" attribute. It holds the number of NICS required to provision the imge. The second is for koan which uses the image metadata to drive the virt-image libraries.
