template_dir config for pxe and power
by Vreman, Peter 20 Nov '08

20 Nov '08

The attached patch makes the directory configurable for PXE and power templates. This is required to make cobbler sync working after the the etcfiles.diff patch is applied.

(devel) Pending network changes
by Michael DeHaan 20 Nov '08

20 Nov '08

To summarize some recent activity. --dns-name is a new field that applies to each interface, it replaces --hostname on each interface, and affects dns management from Cobbler --hostname is now a per-system field that now affects the /etc/sysconfig hostname --static-routes is a new per-interface field that takes a list --gateway is now a per-system field instead of a per-interface field --name-servers is now a per-profile or per-system field, with a default_name_servers value also in /etc/cobbler/settings All of these will be used by the network setup snippets in the new kickstart files. For those of you with existing setups (should be everyone), the cobbler code will be written to migrate settings around automatically, just be aware of the new CLI options and the webapp will be changing slightly by moving some fields around. This is a more-correct modelling of the network as it actually is, so these changes should make cobbler much more usable in the long run. If there are any questions about this, now is the time to ask. For those using the devel branch, except the webapp to be broken as I haven't implemented all of this presently. Similarly, DNS and DHCP management may not be completely in line, so if you are using the development branch for "productiony" things you have been warned :) --Michael

network pre_installation
by Vreman, Peter 19 Nov '08

19 Nov '08

I have issues with bonding and the current pre_network_installation I resolved it by removing all the network pre_install configuration generate and replace it with: network --bootproto=dhcp --hostname=<systemhostname> --gateway=<systemgateway> This will reuse the DHCP that is already there from the PXE. And it will generate the /etc/sysconfig/network. To get the gateway working I modified the post_install_network_config and removed the gateway setting. Was there a reason why we should let anaconda create the network config? Currently all the config is overwritten it in the post_install.

webui sidebar with operations
by Vreman, Peter 19 Nov '08

19 Nov '08

Below is a new proposal for operations tasks in the webui. Change sidebar from a static list and add menu to a nested menu structure. Only for the current selected target distro/system the operations will be shown. The menu structure will be like the CLI: Distros Add Delete Import Systems Add Delete Poweron Poweroff Reboot Enable PXE Change profile Kickstarts Add Rename Delete Copy Profiles Add Delete Rename Copy Repos Add Synchronize Image Add In the list a check box will be added to mark the systems that need operation. This allows actions on multiple systems. Thoughts? Regards, Peter This e-mail and any attachment is for authorised use by the intended recipient(s) only.

number of files in /etc/cobbler
by Vreman, Peter 19 Nov '08

19 Nov '08

When I looked at the pxe templates I noticed the amount of files in /etc/cobbler. Maybe we move some groups of the files to /var/lib/cobbler/xx/ Some ideas: *.ks /var/lib/cobbler/kickstarts (this directory already exists) Pxe* /var/lib/cobbler/pxe Power* /var/lib/cobbler/power On my node this will already move 24 of 36 files out of /etc/cobbler Regards, Peter This e-mail and any attachment is for authorised use by the intended recipient(s) only.

Authentication against multiple ldap servers
by Ruben Kerkhof 19 Nov '08

19 Nov '08

Hi all, We're using two ldap servers (master and slave) for our accounts, so I wrote a patch for cobbler to accept multiple servers separated by spaces, like ldap_server: "ldap1.example.com ldap2.example.com". I'd love to hear from other people using ldap for authentication what you're thoughts are about this. diff --git a/cobbler/modules/authn_ldap.py b/cobbler/modules/authn_ldap.py index d30e87d..e4313e0 100644 --- a/cobbler/modules/authn_ldap.py +++ b/cobbler/modules/authn_ldap.py @@ -59,13 +59,24 @@ def authenticate(api_handle,username,password): anon_bind = api_handle.settings().ldap_anonymous_bind prefix = api_handle.settings().ldap_search_prefix - # form our ldap uri based on connection port - if port == '389': - uri = 'ldap://' + server - elif port == '636': - uri = 'ldaps://' + server + # allow multiple servers split by a space + if server.find(" "): + servers = server.split() else: - uri = 'ldap://' + "%s:%s" % (server,port) + servers = [server] + + uri = "" + for server in servers: + # form our ldap uri based on connection port + if port == '389': + uri += 'ldap://' + server + elif port == '636': + uri += 'ldaps://' + server + else: + uri += 'ldap://' + "%s:%s" % (server,port) + uri += ' ' + + uri = uri.strip() # connect to LDAP host dir = ldap.initialize(uri) -- 1.6.0.3 Regards, Ruben

snippet tag
by Vreman, Peter 19 Nov '08

19 Nov '08

There is some inconsistency in the inclusion of snippets. There are 2 styles used: SNIPPET::network_config $SNIPPET('network_config') What is the preferred way? And can all provided (example) files can be made to use the same style. Regards, Peter This e-mail and any attachment is for authorised use by the intended recipient(s) only.

(devel), by popular demand, highly exciting version command
by Michael DeHaan 19 Nov '08

19 Nov '08

I've resisted adding a version command to Cobbler because rpm and yum provide a better one, and it's not easy to define a version in the age of distributed version control for developer versions when everyone is on a different branch. Returning just one number is wholly insufficient. Packaging for non-rpm distros, however, will require that we have an option, and often folks have the question of when did they last do a checkout. So, cobbler now has a version command: [root@localhost koan]# cobbler --version cobbler 1.3.2 build date : Tue Nov 18 12:30:40 2008 git hash : 9fe5605e0f302d1de76235a4150d3b01e2b6e42c git date : Tue Nov 18 12:27:21 2008 -0500 Copyright (C) 2006-2008 Red Hat, Inc. License GPLv2+: GNU GPL version 2 or later <http://gnu.org/licenses/gpl.html> This is free software: you are free to change and redistribute it. There is NO WARRANTY, to the extent permitted by law. Written by Michael DeHaan. ===== For those applications talking to cobbler remotely, the call remote.extended_version() will return a hash with all of this information. The existing api.version() call is left working as is for backwards compatibility (as koan needs to be able to query any cobbler server). This works by writing a YAML file into /var/lib/cobbler/version, which is fairly low tech, but works nicely. --Michael
