These are information technology notes that somebody told User:Blu to create.
Accounts on MAG Laboratory
Getting an account on this wiki is meant to be difficult. todo: image here
The normal account creation path would be to create an account on the MAG Laboratory "Members Only" section. Currently, this functionality is broken.
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
Below is a directory of common services that may be used on the MAG Laboratory intranet and a copy of our certificate authority (CA) public key. You may want to install the CA on your computer to automatically trust signed MAG Laboratory intranet services.
Google Drive Link to MAG Laboratory CA Public Key
Before that, please ask for the default MAG Laboratory credentials to access anything on publicly available at the MAG Laboratory. Most services will be locked behind the default credentials.
3D Printer
The 3d printer is running a version of octoprint and can be accessed at the link below.
Intranet Speed Test
The intranet speed test can be accessed at the link below. Remember that it only tests the link between your computer and the MAG Laboratory service host, not the internet.
Grafana
Intranet users may be interested in the status of MAG Laboratory's HAL or other devices on the intranet. All Grafana dashboards are set for public viewability. Follow the link below:
Mattermost
Intranet makerspace task organization, checklist, and chat client
Nextcloud
Intranet file storage and sharing server. Runs Nextcloud. Similar to Google Drive?
Outside Cameras
These cameras should be accessed through VLC or another RTSP compatible player. The original camera streams are mirrored and should be viewed through the listed mirror below.
Note: that the default streams are at a rather large resolution. The substreams are recommended.
| Camera | URL |
|---|---|
| Camera 1 | rtsp://maglab:[email protected]:8554/Camera1
|
| Camera 1 Low Bandwidth | rtsp://maglab:[email protected]:8554/Camera1_sub

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

The following addresses are already assigned:
| IP | Assignment |
|---|---|
| .1 | WG server |
| .2 | Brandon's laptop |
| .3 | Richard's laptop |
| .4 | Brandon's Moto phone |
| .5 | Brandon's Pixel phone |
| .8 | Michael |
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.
