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, logresolve has its very own inter-
       nal  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 seperated 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 original address.
