I was working on my new server and decided my network connection what setup wrong so I adjusted the settings file. In a moment of unusual clarity I realized this was the connection I was using to access the machine via ssh and if something went wrong I was in trouble - so I verified that this machine was also reachable via ssh from the other ethernet interface that was directly connected to my NAS. I was right, my first config changes did break the network, but I still had the backup connection option and so I was able to recover.

    Good move. I have my home network and its home lab the same way I run my work networks and server clusters:

    1. Management network over regular copper ethernet. This is what’s routed over VPN for remote access. IPMI also connects here for when something really stupid happens.
    2. High speed fiber connecting all the servers. Not routed out - it’s only used for comms between the servers. This serves as a backup in case the management port dies. It has saved me a couple of times: shell in to one of the others the normal way, the from there I can jump into any other server via the fiber connection.
