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

Assuming that character classes are supported within REGEX[ ]:

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