66 Intel NetStructure Cache Appliance Administrator’s Guide
The following table describes the tags you can use in a rule:
Tag Description
hostname Choose one of the following:
❚host name
❚host name:port
❚IP address
❚IP address:port
❚.block—Use .block to block access to specific
news groups.
group-wildmat This tag must be a comma-separated list of group
names and list files in wildmat format (use * as a
wildcard). The list file options are: subscriptions,
distributions, and distrib.pats.
Do not use spaces in the list. Use the prefix “!” to
indicate groups not included in the list. The list is
processed in reverse order, so more specific
restrictions should be placed later in the list.
Examples:
❚*,!distrib.pats
The previous example does not include any
distrib.pats files, but does include all others.
❚*,!alt.*
The previous example does not include any
groups of the form alt.*, but does include all
others.
❚talk.religion.*,!talk.religion.barney
,subscriptions
The previous example includes only subscriptions
from all talk.religion.* groups but excludes
talk.religion.barney.
priority This tag tells the appliance how to treat the specified
host and news groups. Use one of the following
options:
❚<no priority tag>
If you do not use a priority tag, the appliance
caches articles from the specified news groups on
demand. If you specify multiple groups (such as
alt.*), the appliance maintains a group list and
will poll the parent NNTP server regularly to check
for changes in the group list.
