[Zyxel] [Network] Saving Configuration is helpful

I just spent a good half hour trying to find out why an uplink to a 2nd location was not working after unplugging the network equipment very briefly due to UPS swapping .. Seems like I had failed to save configuration on my Zyxel GS 1920 backbone switch .. Having Link Aggregation on ports 25-28 when you only need 25,27 because 26 and 28 now go to a different building and server is definitely never going to work ..

nftables routing .. working now ;)

So I was thinking of replacing my iptables stuff with nftables .. so what better chance to use than a new server in a seperate network segment - hardware wise, and a different subnet.

Python network "scanner"

So i wanted to know what hosts in my network are up and what are their mac addresses.

Free & Open DNS servers

So I was setting up yet another (caching) bind DNS .. so to decide which DNS servers to use as forwards ... First thoughts were openDNS and google's public dns..
