A.1.4. Differentiating between Config Files
To obtain a difference between the config files deployed on the system and those for it stored by RHN,
issue the command:
rhncfg-client diff
You should see output resembling:
--- /tmp/@3603.0.rhn-cfg-tmp 2004-01-13 14:18:31.000000000 -0500
+++ /etc/foo.txt 2003-12-16 21:35:32.000000000 -0500

In addition, you may include the
--topdir
option to compare config files in RHN with those located
in an arbitrary (and unused) location on the system, like so:
[root@ root]# rhncfg-client diff --topdir /home/test/blah/
/usr/bin/diff: /home/test/blah/etc/foo.txt: No such file or
directory
/usr/bin/diff: /home/test/blah/var/spool/aalib.rpm: No such file or
directory
A.1.5. Verifying Config Files
To quickly determine if files are different than those associated with it in RHN, issue the command:
rhncfg-client verify
You should see output resembling:
modified /etc/foo.txt
/var/spool/aalib.rpm
The file
foo.txt
is locally modified, while
aalib.rpm
is not.
A.2. Red Hat Network Configuration Manager
Unlike the Red Hat Network Configuration Client , the Red Hat Network Configuration Manager
(
rhncfg-manager
) is designed to maintain RHN’s central repository of config files and channels,
not those located on client systems. This tool offers a command line alternative to the configuration
management features within the RHN website, as well as the ability to script some or all of the related
maintenance.
It is intended for use by Config Administrators and in fact requires an RHN username
and password that has the appropriate permission set. The username may be specified in
/etc/sysconfig/rhn/rhncfg-manager.conf
or in the [rhncfg-manager] section of
~/.rhncfgrc
.
