check_dnsbl

Project Notes

Perl plugin that checks a specified DNS blacklist such as bl.spamcop.net to see whether a host is listed. Blacklists can be used to identify misbehaving servers, zombie PCs, and other machines worthy of a sysadmin's attention. Depends on Net::DNS. Usage: > > check_dnsbl -H host -B blacklist -T target -t timeout -v -v > check_dnsbl --help > If you only care about a specific sub-list (see your blacklist's information page for these result addresses), you can specify it with the -T option. For testing purposes, try 127.0.0.2 as the host: > > check_dnsbl -H 127.0.0.2 -B bl.spamcop.net -v -v > You might want to put this in {{checkcommands.cfg}}: define command{ command_name check_sorbs command_line $USER1$/check_dnsbl -H $HOSTADDRESS$ -B dnsbl.sorbs.net } define command{ command_name check_spamcop command_line $USER1$/check_dnsbl -H $HOSTADDRESS$ -B bl.spamcop.net } Then in {{services.cfg}}, all you need is {{check_command check_sorbs}} or {{check_command check_spamcop}} in the right place.
