<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.
