NAME
       logresolve - Resolve IP-addresses to hostnames in Apache log files


SYNOPSIS
       logresolve [ -s filename ] [ -c ] < access_log > access_log.new



SUMMARY
       logresolve  is  a  post-processing  program to resolve IP-addresses in
       Apache's access logfiles.  To  minimize	impact	on  your  nameserver,
       logresolve has its very own internal hash-table cache. This means that
       each IP number will only be looked up the first time it	is  found  in
       the log file.


       Takes  an  Apache log file on standard input. The IP addresses must be
       the first thing on each line and must be seperated from the  remainder
       of the line by a space.



OPTIONS
       -s filename
	      Specifies a filename to record statistics.

       -c     This  causes logresolve to apply some DNS checks: after finding
	      the hostname from the IP address, it looks up the IP  addresses
	      for the hostname and checks that one of these matches the orig-
	      inal address.
