Main Session


David Farrar (Exa Networks)Mr Marek Isalski (Faelix Limited)


First part of the talk: what is Teleport, how do you use it, what might the use-cases be in a NOC environment. Second part of the talk: how Exa Networks used Teleport and a bunch of Raspberry Pis to find a serious performance problem in the default config of one particular vendor's firewalls.


Marek already has the first half written (attached) but it will be revamped for UKNOF's audience, and trimmed down to focus on how Teleport might be used in a NOC environment (ISO27001 and PCI-DSS compliance, etc).

David will then explain the tooling he built and deployed on a bunch of remotely-controlled (via Teleport) Raspberry Pi devices which were embedded into customers' networks to run diagnostics - bits involving InfluxDB and some custom-written scripts. The resulting data he gathered pointed the finger firmly at the TCP timeouts of a particular vendor's firewalls.

Possibly wrap-up at the end from Marek with a live demo.
