README.SUSE for monitoring-plugins-dhcp

== check_dhcp and SuSEfirewall ==

If you run the check_dhcp script on the server, please make sure your UDP ports
67 and 68 on the _client_ are opened in the firewall. You also need to allow
to receive broadcasts for this interface. Otherwise  the script will be unable
to detect anything.

Example:
If your client uses the "external" interface for the check, the entries in
/etc/sysconfig/SuSEfirewall2 should look like:

FW_SERVICES_EXT_UDP="67 68"
FW_ALLOW_FW_BROADCAST_EXT="67 68"

== Special privileges ==

To be "safe per default", SUSE doesn't install this plugin with the
suid bit set. There are two recommended ways about overriding this on
your system:

=== Set the suid bit ===

Copy the prepared permissions file from this directory to the right place 
in your file system:

~ # cp /usr/share/doc/packages/monitoring-plugins-common/example/permissions.d/monitoring-plugins \
    /etc/permissions.d/monitoring-plugins

...afterwards adapt the file /etc/permissions.d/monitoring-plugins to your needs
(see comments in the file) and run:

~ # SuSEconfig --module permissions

or (on newer openSUSE distributions without SuSEconfig):
~ # chkstat --system --set

This will set the correct permissions (from now on also during an update).

=== Alternative: Use sudo to grant the permission and modify your plugin config ===

This way you just need an entry like:

nagios ALL = NOPASSWD: /usr/lib/nagios/plugins/check_dhcp

in ''/etc/sudoers'' and an adapted command definition like the following:

define command{
        command_name    check_dhcp
        command_line    /usr/bin/sudo $USER1$/check_dhcp <other_options_here>
   }

== Apparmor profile ==

Please check /etc/apparmor.d/usr.lib.nagios.plugins.check_dhcp if you are using
the --extra-opts option. The Apparmor profile allows to open every file below
the /etc/monitoring-plugins/ directory read only for this. All files in other
directories are not allowed.
