.SH DESCRIPTION
|
|
.B 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.
|
|
.SH OPTIONS
|
|
.TP 12
|
|
.BI \-s " filename"
|
|
Specifies a filename to record statistics.
|
|
.TP 12
|
|
.B \-c
|
|
This causes
|
|
.B 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.
