This evening I successfully moved a second set of services from service provider IP space to BGP IP space. The first phase of this project began over a year ago -- I turned up AS62758 in early December 2013 prior to the migration of a Learning Management System.
One of the most exciting new features to me in SaltStack 2014.7 is the nagios module. This module supports remote execution of nagios-plugins on your minions. It can also execute pre-defined lists of checks and targets defined (and targeted) in a Pillar.
As part of maintaining my list of Manitoban ASNs and their IPv6 status, I need to determine new Canadian, and specifically, Manitoban ASNs issued by ARIN. I had been doing this manually by reading through bgp.he.net/country/CA, but this was very time consuming, and very prone to error/being banned.
I've previously written about my OpenBSD PF firewall in front of my VM server at my colo. I had a firewall rule which used the following variable: icmp6_types="{ 2, 128 }". This wasn't working properly on the LAN side, and I had to disable the ICMPv6 restrictions to get things back to working. I wanted to fix this permanently, the right way, by determining what needed to be allowed and what could be denied without breaking things.
