NAME
logresolve - resolve hostnames for IP-addresses in Apache
logfiles
SYNOPSIS
logresolve [ -s filename ] [ -c ] < access_log >
access_log.new
DESCRIPTION
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.
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 origi-
nal address.
