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,	logre-
       solve 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 separated 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	origi-
	      nal address.
