Example -- Changing the Label of the 0.0.0.0 Tnrhdb Entry

You may want to give the 0.0.0.0 tnrhdb(4) entry a different unlabeled template, such as the unclassified template from the default set of templates. The system then recognizes any computer not otherwise listed in its tnrhdb file as an unlabeled machine at the label unclassified. Choose Action --> Properties from the menu when 0.0.0.0 is selected to change the assigned template.

Many sites create an unlabeled template specifically for gateways, and assign the gateway template to all gateway systems. The following is an unlabeled template specifically for gateways,

unlab_gateway:host_type=unlabeled;\
def_label=[0x00010000000000000000000000000000000000000000000000000000000000000000];\
def_cl=0x00010000000000000000000000000000000000000000000000000000000000000000;\
forced_privs=empty;\
min_sl=0x00000000000000000000000000000000000000000000000000000000000000000000;\
max_sl=0x7fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff;\
doi=0;\
ip_label=none;\
ripso_label=empty;\
ripso_error=empty;

The backslashes above are for ease of reading. See "To Construct Templates for Hosts" for how to construct a template, and then assign it to the 0.0.0.0 wildcard.
