Minecraft

MAG Laboratory is running a modded minecraft server as of the time of this writing. The server has two standout technology mods for your enjoyment: Ad Astra and Tech Reborn. There is also Farmer's Delight and other quality of life mods for your enjoyment along with a host of performance enhancement mods.

The minecraft server originally started as an open house event on 2022-10-08.

Upon spawning into the minecraft world, the central base will be to your East. There is also our local village complete with commieblock to the East but across an ocean.

The client is downloadable from the following intranet link: https://stor.maglab/s/WWkHtM85YsnEffp

Local IT support is available.

Maintenance Log

2022-11-14: Minecraft client and server were updated to the latest versions of the mods. Still running 1.19.2.

IP Assignment on the MAG Laboratory Network

The local DHCP only assigns IP addresses from 192.168.254.100 to 192.168.254.245. Addresses below 100 are assigned statically by the DHCP and are listed here:

Note that the local DNS assigns addresses to *.maglab. This makes it so that you should find the router under router.maglab.

VSFTP is very picky about home chroot permissions and will exit with 500 OOPS: vsftpd: refusing to run with writable root inside chroot() if the chroot is writeable.
