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.
