wcmgr - Webalizer (DNS) Cache file Manager
wcmgr [ option ... ] cache-file
wcmgr is a utility program which allows manipulation of the DNS cache
files used and produced by The Webalizer. Each record in the cache
file contains an IP address (either IPv4 or IPv6), a timestamp of when
the entry was added to the cache, a flag to indicate if the record con-
tains a resolved name or not, and either the same IP address or a
resolved host name. All records are accessed by their IP address.
wcmgr was designed to be run from the Unix shell command line. This
facilitates its use in shell scripts and other automated processes. A
valid DNS cache file must be specified. Command line options are
optional, and if none are given, the default action is to list the con-
tents of the specified cache file.
COMMAND LINE OPTIONS
Different functions are selected by using one or more of the following
command line options. If no options are given, the default is to dis-
play the contents of the cache file to the screen (stdout).
-h Display all available command line options and exit.
-v Be verbose.
-V Display the program version and exit. Additional program spe-
cific information will be displayed if verbose mode is also
used (e.g. '-vV'), which can be useful when submitting bug
-a address [-n hostname] [-t0]
Add a new record to the cache file. The IP address will be
added to the cache file using the current time as the timestamp
and with a resolved name hostname. If -t0 is specified, the
record will be considered permanent, and will not be removed
(during a purge) or expired. If a hostname is not specified
with the -n option, then the address will be used instead, and
the record will be flagged as unresolved.
-c Create a new cache file. If used alone, this option will cre-
ate a new, empty cache file. If used with the import option, a
new cache file will be created before importing the data. An
error will occur if the file cache-file already exists.
Delete a record from the cache file using the specified
Find and display information for address from the cache file.
A single line similar to that produced by the -l option will be
displayed unless verbose mode is enabled, in which case a more
detailed listing will be produced.
-i name [-c]
Import data into the cache file from the file name. The import
file must be a valid tab delimited text file, such as that cre-
ated by the export option. If the imported data contains
records already present in the cache file, those records will
be overwritten by the imported data. The cache file must exist
unless the -c option is specified, in which case, a new cache
file will be created for the imported data.
-l List the contents of the cache file. This is the default
action of the program, so does not necessarily need to be spec-
ified. If verbose mode is enabled, a report title, column
headers and summary totals will also be displayed.
-p num Purge the cache file of entries older than num days. If num is
not specified, then a default of 7 days will be used. if ver-
bose mode is enabled, each purged record will be printed and
the total number of purged records will be displayed.
-s [-t num]
Display cache file information/statistics. If a TTL value (in
days) is specified using the -t option, it will be used to cal-
culate how many records are older than num days, otherwise, the
default value of 7 days will be used.
-n name Specify the name to use as the resolved hostname when adding
records to the cache.
-t num Time to live (TTL) value. If used along with the -p (purge)
option, it specifies how many days a record will remain valid.
Any record that is older than num days is considered expired
and will be purged. If used with the -a (add) option, a zero
value will cause the record to be considered permanent.
-x name Export data from a cache file to a tab delimited text file
named name. If the text file name exists, it will be overwrit-
