<strong>NAME</strong>
     logresolve - resolve hostnames  for  IP-addresses  in  Apache
     logfiles

<strong>SYNOPSIS</strong>
     <strong>logresolve</strong>  [  -<strong>s</strong>  <em>filename</em>  ]  [  -<strong>c</strong>  ]  &lt;   <em>access</em>_<em>log</em>   &gt;
     <em>access</em>_<em>log</em>.<em>new</em>

<strong>DESCRIPTION</strong>
     <strong>logresolve</strong> 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.

<strong>OPTIONS</strong>
     -<strong>s</strong> <em>filename</em> Specifies a filename to record statistics.

     -<strong>c       </strong>   This causes <strong>logresolve</strong> 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.
