| <title>logresolve - Resolve IP-addresses to hostnames in Apache |
| log files</title> |
| |
| <summary> |
| <p><code>logresolve</code> 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.</p> |
| |
| <p>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.</p> |

| <dd>Specifies a filename to record statistics.</dd> |
| |
| <dt><code>-c</code></dt> |
| |
| <dd>This causes <code>logresolve</code> 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.</dd> |
