| The script reads stdin and replaces all IP addresses with names before | |
| outputting it again. IPs from private networks are reverse looked up | |
| via dns. Other IP addresses are searched for in the dnsmasq query log. | |
| This gives names (CNAMEs if I understand DNS correctly) that are closer | |
| to the name the client originally asked for then the names obtained by | |
| reverse lookup. Just run | |
| netstat -n -4 | ./reverse_replace.sh | |
| to see what it does. It needs | |
| log-queries | |
| log-facility=/var/log/dnsmasq.log | |
| in the dnsmasq configuration. | |
| The script runs on debian (with ash installed) and on busybox. | |
