NAME
       logresolve2 - Resolve IP-addresses to hostnames in Apache log files


SYNOPSIS
       logresolve2 [ -s filename ] [ -c ] < access_log > access_log.new



SUMMARY
       logresolve2 is a post-processing program to resolve IP-addresses in
       Apache's access logfiles. To minimize impact on your nameserver,
       logresolve2 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 logresolve2 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
              original address.
