Free xtended software for linux

Webalizer Xtended is an extension of Webalizer, which adds additional monthly statistics for all "404 Not Found" errors found in your server log-file, including the number of the "404 Not Found" requests and the corresponding 404 URLs.
Webalizer Xtended project also fixes truncated user agent strings in the "User Agents" statistics, so user agent fields can now be grouped more precisely. It is helpful for detecting and correcting broken links or invasion attempts.
