Please e-mail either the contact at maglaboratory or the webdev at maglaboratory to ask for a wiki account. It is also possible to DM in an appropriate managed social media account.

MAG Laboratory IT Services

Wireguard

Wireguard is the name of a VPN solution which requires MAG Laboratory to pre-define IP addresses for VPN users.

These addresses are on the 192.168.128.0/24 subnet.

The following addresses are already assigned:

Address	Assignment
.1	WG server
.2	Brandon's laptop
.3	Richard's laptop
.4	Brandon's phone

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.
