UCS 2.4 - Univention

14 Univention Configuration Registry
Univention Configuration Registry must be executed via the command eval for Univention Configuration
Registry variables to be able to be read in a shell script as environment variables:
# eval $(univention-config-registry shell ldap/server/name)
# echo $ldap_server_name
master.firma.de
14.4 Changing Univention Configuration Registry variables
The command
univention-config-registry set =""
can be used to change a variable’s value. This initiates a syntax check. In the following example, the value
of the variable nameserver1 is set to 192.168.0.1:
univention-config-registry set nameserver1="192.168.0.1"
The change to a Univention Configuration Registry variable results in all configuration files for which the
Univention Configuration Registry variable is registered (see Chapter 14.8), being rewritten immediately.
The files in question are output on the terminal output:
# univention-config-registry set sshd/xforwarding=yes
Setting sshd/xforwarding
File: /etc/ssh/sshd_config
In doing so it must be noted that although the configuration of a service is updated, the system service
in question is not restarted automatically. These services must generally be restarted manually using the
corresponding init scripts below /etc/init.d. The execution of scripts to follow changes to Univention
Configuration Registry variables is described in Chapter 14.10.
If, for example, the debug level of the Samba service is changed, this must then be restarted:
# univention-config-registry set samba/debug/level=2
Setting samba/debug/level
Multifile: /etc/samba/smb.conf
# /etc/init.d/samba restart
Stopping Samba daemons: nmbd smbd.
Starting Samba daemons: nmbd smbd.
Simultaneous changes to more than one variable are possible in one command line (in so far as they refer
to the same configuration file, this will only be rewritten once):
# univention-config-registry set \
dns/forwarder1=192.168.0.2 \
sshd/xforwarding="no" \
sshd/port=2222
