# Manual Page: logresolve

    NAME
         logresolve - resolve hostnames  for  IP-addresses  in  Apache
         logfiles

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

    DESCRIPTION
         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.

    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.
