I decided to get a lot of IT work done this weekend. One of my major goals was to get my lab systems on to a virtual network. The virtual network uses NAT for outbound connectivity but does allow some things inbound. I had to do this the manual way and it’s been a challenge. One of the things that makes Linux and BSD so powerful are their networking tool set. With the pretty much stock install, you can set up an entire virtual network within a host. If you’re willing to roll up your sleeves, there are some very cool things to do.
The first thing I did was create a virtual network with a bridge on my server called virbr10. The virbr10 has a dummy interface called virbr10-dummy. The dummy interface is just to keep the bridge in an up state while the virtual machines load on boot. It’s an important thing to do so that the boot time is faster.
This consolidation is ultimately a good thing but taking a lot longer than I had planned. I am still wrestling with getting my Mastodon instance moved but that’s okay. I know Mastodon can be really finicky. It’s not tolerant of stupid/arrogant sysadmins. 😆
