It’s been more than six months that I’ve been using NethServer. My go to replacement from Zentyal. Zentyal was one of those systems that if you didn’t maintain it it would break on it’s own. You couldn’t set it and forget it, there was always some service crashing that resulted in having to restart the service which would only cause more issue. Even rebooting the server may not help.
NethServer has been the BEST drop in place system I’ve used thus far. It runs without any issues, hell I even experienced a brown out where one of my servers rebooted and recovered without me even knowing about it. If that were Zentyal, the server would have been down for days.
My point is, I haven’t been very active on this forum; why? Because I don’t need to be. The system just works for what I need it for. I update it occasionally and move on.
