Once I finish #n4sa, I go on to OpenZFS Mastery with @allanjude. But after that, torn between a DNS book and a "Netflow for Sysadmins" book.
Zimmie@mwl Some sort of OpenTelemetry for Network Admins book could also be interesting. Firewalls, load balancers, and routers are basically all just weird servers, and the server admin space has some great tools for monitoring system performance.
Scruffy looking packet herder@mwl @allanjude The world desperately needs an updated Netflow book. But, of course, I would say that.
Preuk@mwl my money is on DNS 😁
Thomas A. Frederiksen@mwl @allanjude I could see the point of Netflow. I know far too much about DNS as it is…
slash@mwl @allanjude My vote is Netflow; I've never quite understood how to apply it in a way that makes sense.
