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.
