NAME

bgpmon-filter - Critical Prefix Filter

This script can connect to a BGPmon instance and filter messages that match given critical prefixes. These messages can then be sent to other clients that connect to this instance, can be saved to a file, or printed to standard out.

SYNOPSIS

This script allows one to specify a set of configuration parameters and a list of desired critical prefixes or autonomous system numbers. This script will then connect to the specified instance of BGPmon and filter the messages it receives. If a given message has data for one of our given prefixes or any address within that prefix, it will pass it along to other cliences connected to it, print it to standard out, or save it to a file. These are options the user may set before running an instance.

Users may create a configuration file for easy command-line use. Below is an example of a full configuration file:

   config_file   =  /home/user/bgpmon-filter.confg
   output_file   =  /tmp/bgpmon-filter-output.txt
   prefix_file   =  /home/user/bgpmon-filter-prefixes.conf
   log_file      =  /tmp/bgpmon-filter-log.log
   log_level     =  7
   server        =  bgpmon2.netsec.colostate.edu
   port          =  50001
   listening_port=  60000
   stdout        =  1

This configuration will connect to a BGPmon instance at bgpmon2.netsec.colostate.edu:50000 and will listen for connections on 60000. It will look for a list of critical prefixes to filter in file /home/user/bgpmon-filter-prefixes.conf. All messages that match the prefixes will be printed to standard out and will be saved in file /tmp/bgpmon-filter-output.txt. Note that if you have a configuration file already and want to change variables for a run, you may do so using command line arguments. They will override any variables set from the configuration file. You may see a list of all options by running ./bgpmon-filter -h.

The following is an example of the critical prefix configuration file:

        ipv4    207.132.222.0/24 ms
        ipv4    10.10.0.0/16 ls
        as      1733
        ipv6    2a02:1378::/32 ls
        ipv6    1020:9a52::/32 ms
        ipv4    192.168.1.135

You may have multiple prefixes of all kinds and don't have to be in any order within the file. For mor information on this file configuration, please see the perldoc for BGPmon::Filter.pm.
