🌐 Remote settings

SSH

sudo apt install -y openssh-server
sudo service ssh start

Suppose you have a <STATIC_IP> for the host computer. You should be able to connect with

ssh <USER>@<STATIC_IP>

If you are using a router, go to DHCP settings or Address Reservation and assign a <ROUTER_STATIC_IP> to your host computer. Then, go to the Port Forwarding or NAT to add a port on <ROUTER_STATIC_IP> with

• external port: <PORT> (router to host)
• internel port: 22 (default SSH port)

ssh <USER>@<STATIC_IP> -p <PORT>

(rare case) I used SSH before on the same host computer, I re-installed it, and got some error while setting SSH again. The reason is that there is some old information in the SSH configuration, you need to clean it.

VSCode server

curl -fsSL https://code-server.dev/install.sh | sh

Generate a configuration file by running code-server. Quit it. Modify the configuration file:

vim ~/.config/code-server/config.yaml

You should see this

bind-addr: 127.0.0.1:8080  
auth: password       
password: <RANDOM_PASSWORD> 
cert: false 

Change it to

bind-addr: 0.0.0.0:<PORT>  
auth: password       
password: <CUSTOM_PASSWORD> 
cert: false 

If you are using a router, go to DHCP settings or Address Reservation and assign a <ROUTER_STATIC_IP> to your host computer. Then, go to the Port Forwarding or NAT to add a port on <ROUTER_STATIC_IP> with

• external port: <PORT> (router to host)
• internel port: <PORT> (code-server port)

systemd service

The following is to auto-run code-server at boot on Ubuntu by setting it up as a systemd service.

sudo touch /etc/systemd/system/code-server.service
sudo vim /etc/systemd/system/code-server.service

Write this in your service file

[Unit]
Description=Code-Server
After=network.target

[Service]
Type=simple
User=chern
ExecStart=/usr/bin/code-server
Restart=always

[Install]
WantedBy=multi-user.target

Then run

sudo systemctl enable code-server
sudo reboot

You should be able to access code-server after booting.
