NAME

logresolve - resolve hostnames for IP-adresses in Apache logfiles

SYNOPSIS

logresolve [ -s filename ] [ -c ] < access.log > access.log.new

DESCRIPTION

logresolve is a post-processing program to resolve IP-adresses 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 original address.
