After a few network dropouts while playing Elite: Dangerous I was busy trying to find where the network failure was and decided I needed some help. PingLog is a (very) simple tool that allows a network ping to a specified host at the defined interval. If it fails then it pings a secondary address. The failure and subsequent pings are then logged.
I used this to determine that when I had issues to elite, local addresses where still reachable but the router was not – the problem is with intermittant interference on my HomePlug network.
