Not quite at my level, but very interesting. A practical exercise to try again at my own pace once I’ve gained more experience and, above all, improved my technique.

A very comprehensive course; I would have liked a bit more time spent on syslog (both practical sessions and lectures). A good trainer who listened to the participants.
