University Network Debugging

  • IPv6 multicast multiplication/dropping - IPv6 Matrix]
  • SSH command line latency. (Use OpenConnect and SSHPing across two Raspberry Pis)
    • Median latency is comparable on and off the VPN from outside to login.ecs but average latency is twice as high (70ms vs 35ms) and maximum latency is 5 times as much (300ms vs 60ms). Anything more than 100ms is likely to cause notice command line lag.
  • External ping to ECS DMZ servers (see MARCONI/EXT-PING checks on Wednesday)


  • Nothing urgent
