Setting up a new school with Debian Edu/Squeeze
25th January 2012

The next version of Debian Edu / Skolelinux will include a new tool sitesummary2ldapdhcp, which can be used to quickly set up all the computers in a school without much manual labour. Here is a short summary on how to use it to set up a new school.

First, install a combined Main Server and Thin Client Server as the central server in the network. Next, PXE boot all the client machines as thin clients and wait 5 minutes after the last client booted to allow the clients to report their existence to the central server. When this is done, log on to the central server and run sitesummary2ldapdhcp -a in the konsole to use the collected information to generate system objects in LDAP. The output will look similar to this:

% sitesummary2ldapdhcp -a
info: Updating machine tjener.intern [] id ether-00:01:02:03:04:05.
info: Create GOsa machine for auto-mac-00-01-02-03-04-06 [] id ether-00:01:02:03:04:06.

Enter password if you want to activate these changes, and ^c to abort.

Connecting to LDAP as cn=admin,ou=ldap-access,dc=skole,dc=skolelinux,dc=no
enter password: *******

After providing the LDAP administrative password (the same as the root password set during installation), the LDAP database will be populated with system objects for each PXE booted machine with automatically generated names. The final step to set up the school is then to log into GOsa, the web based user, group and system administration system to change system names, add systems to the correct host groups and finally enable DHCP and DNS for the systems. All clients that should be used as diskless workstations should be added to the workstation-hosts group. After this is done, all computers can be booted again via PXE and get their assigned names and group based configuration automatically.

We plan to release beta3 with the updated version of this feature enabled this weekend. You might want to give it a try.

Update 2012-01-28: When calling sitesummary2ldapdhcp to add new hosts, one need to add the option -a. I forgot to mention this in my original text, and have added it to the text now.
