Basics

This section covers fundamental system administration tasks on TeamSBC.

Privilege Escalation

TeamSBC does not include sudo. Instead you can use run0 to run commands as root.

$ run0 hostnamectl set-hostname mydevice

Managing Services

Services are managed through systemctl.

Starting and stopping a service

$ run0 systemctl start sshd.service
$ run0 systemctl stop sshd.service

Enabling and disabling a service

Enabling a service means it will start automatically on boot. Disabling it removes that behavior.

$ run0 systemctl enable sshd.service
$ run0 systemctl disable sshd.service

Checking service status

$ systemctl status sshd.service

Viewing Logs

System logs are managed by journald and can be viewed with journalctl.

Viewing logs for a specific service

$ journalctl -u sshd.service

Following logs in real time

$ journalctl -f

Viewing logs from the current boot

$ journalctl -b

System Information

Hostname

$ hostnamectl

Time and timezone

$ timedatectl

To change the timezone:

$ run0 timedatectl set-timezone Europe/Amsterdam
