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 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 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.
