How do I specify IP Ranges (RegEx) for SkipHosts in AWStats config files?

Question

I'm updating some old AWStats config files to filter out some specific IP ranges. Here's the pertinent section of the config file:

# Do not include access from clients that match following criteria.
# If your log file contains IP addresses in host field, you must enter here
# matching IP addresses criteria.
# If DNS lookup is already done in your log file, you must enter here hostname
# criteria, else enter ip address criteria.
# The opposite parameter of "SkipHosts" is "OnlyHosts".
# Note: Use space between each value. This parameter is not case sensitive.
# Note: You can use regular expression values writing value with REGEX[value].
# Change : Effective for new updates only
# Example: "127.0.0.1 REGEX[^192\.168\.] REGEX[^10\.]"
# Example: "localhost REGEX[^.*\.localdomain$]"
# Default: ""
#
SkipHosts=""

I want to, for example, filter out X.Y.Z.[97-110]

I tried this format (Note: Not these IP values, using private range as example):

REGEX[^192\.168\.1\.[97-110]]

But it causes the following error:

CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers.

I hate how everything uses a different RegEx syntax. Does anyone have any idea how this one works, and how I can specify a range here?

Answer 1

Does AWStats run if you leave SkipHosts empty? Otherwise, try the commandline utility to check for errors. For example, using Windows:

c:\perlpath\perl.exe awstats.pl config=yourconfigfile -update -logfile=yourlogfile

That should give more details.

Answer 2

Assuming that character classes are supported within REGEX[ ]:

SkipHosts = "REGEX[^192\.168\.1\.(9[7-9]|10[0-9]|110)$]"

Answer 3

The regex you used specifies 9 or 7 to 1 or 1 or 0 which messes up.

You can use

SkipHosts="REGEX[^192\.168\.1\.(97|98|99|100|101|102|103|104|105|106|107|108|109|110)]"

if you're so inclined
