SUMMARY

15       logresolve  is  a  post-processing  program  to resolve IP-addresses in
16       Apache's access logfiles. To minimize impact on your nameserver, logre‐
17       solve  has its very own internal hash-table cache. This means that each
18       IP number will only be looked up the first time it is found in the  log
19       file.
20
21
22       Takes  an  Apache  log file on standard input. The IP addresses must be
23       the first thing on each line and must be separated from  the  remainder
24       of the line by a space.

OPTIONS

29       -s filename
30              Specifies a filename to record statistics.
31
32       -c     This  causes  logresolve to apply some DNS checks: after finding
33              the hostname from the IP address, it looks up the  IP  addresses
34              for the hostname and checks that one of these matches the origi‐
35              nal address.
