bgpmon-filter.pl - Critical Prefix parser
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.
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.
This will read from a default configuration file located at /usr/local/etc/bgpmon-analytics.conf. Below is an example of a full configuration file:
config_file = /usr/local/etc/bgpmon-filter.confg output_file = /tmp/bgpmon-filter-output.txt prefix_file = /usr/local/etc/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 /usr/local/etc/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.pl -h.
The following is an example of the critical prefix configuration file:
ipv4 22.214.171.124/24 ms as 1733 ipv6 2a02:1378::/32 ls
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.
