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.
