| .SH "SUMMARY" |
| |
| .PP |
| 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\&. |
| |
| .PP |
| Takes an Apache log file on standard input\&. The IP addresses must be the first thing on each line and must be separated from the remainder of the line by a space\&. |
| |
| |
| .SH "OPTIONS" |
| |
| |
| .TP |
| -s \fIfilename\fR |
| Specifies a filename to record statistics\&. |
| .TP |
| -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\&. |
