Rebbler

A tool for testing a mail server or IP against a DNS RBL.

NOTE: This project has moved to https://gitlab.xforty.com/xforty/rebbler

Usage

gem install rebbler

Use builtin web app

rebbler -s

Browse to localhost:4567.

Note that the server uses web sockets, so use a modern browser.

From the command line

rebbler -s ip|name

As a nagios plugin check

rebbler -n ip|name

When using as a nagios plugin, the check command definition we use looks like this:

define command{
  command_name  check_rbl
        command_line    bash -l -c 'rvm-exec /usr/local/rebbler/bin/rebbler -n $HOSTADDRESS$' 
  }
