Basics
Hosts Files
located in /etc/hosts this is one of the most critical files you will ever learn
Netplan
I suppose it is good because smarter people than I adopted it.
The config is very very sensitive to spacing.
ZeroTier
This allows you direct access to any computer as if it had a static IP.
I wish I had learned about this early on.
It allows easily for remote printing and direct NoMachine access.
Scan WiFi for Signal Strength
There are many tools to do this.
| SIGNAL STRENGTH | EXPECTED QUALITY | REQUIRED FOR |
|---|---|---|
| -30 dBm | Maximum signal strength, you are probably standing right next to the access point. | |
| -50 dBm | Anything down to this level can be considered excellent signal strength. | |

Ethernet Connection between computers(Link-Local)
You can connect any two computers in linux. You can get up to 35 mb/s transfer speeds.
Procedure
- Connect the cable ethernet to ethernet
- The computers will try to auto config but it will fail.
- Go to the settings for the connection and change the ipv4 setting to link-local
- Repeat on the other computer.
- Now you can ssh or mount the remote computer.
- We use fish in dolphin\
- fish://user@host
Very convenient when setting up a new computer and you only have a wifi network.
