LOGRESOLVE(8)           OpenBSD System Manager's Manual          LOGRESOLVE(8)

NAME
     logresolve - resolve hostnames for IP addresses in Apache logfiles

SYNOPSIS
     logresolve [-c] [-s filename] < access_log > access_log.new

DESCRIPTION
     logresolve is a post-processing program to resolve IP addresses in
     httpd(8)'s access logfiles.  To minimize impact on the 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.

     The following options are supported:

     -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 them
                    matches the original address.

     -s filename    Specifies the filename to record statistics.
