Command Line Tools
This page introduces how to use LibCyber's command line tool cyber.
Installation
Current latest version: v1.2.1
One-click script installation (recommended)
It is recommended to install under the root user (non-sudo) on Linux. Otherwise, permission problems may occur when setting up auto-start at boot and turning on TUN mode.
wget -O getcyber.sh getcyber.sh && bash getcyber.sh
Manual installation (for use in restricted environments)
If your system environment does not have real sudo permissions, cannot access dbus, is in a container (which may be encountered when using a shared GPU or AI model rental service), cannot use the systemd service, etc., follow the steps below to install it. Note that the cyber core installed in this way will not start automatically at boot. After each restart of the server, you need to manually execute cyber core start before it can be used normally.

Stop and delete with one click
Prepare a script file, such as cyber-remove.sh, with the following content:
#!/bin/bash
set -e
cyber core stop
cyber purge -f
rm -rf /usr/bin/cyber /usr/bin/cyber-core /usr/local/bin/cyber /usr/local/bin/cyber-core
rm -rf /usr/local/cyber/ ~/.cyber/core/ /etc/cyber-core/ /etc/cyber/ /var/log/cyber-core/ /var/log/cyber/
rm -f /etc/systemd/system/cyber-core.service
systemctl daemon-reload
systemctl reset-failed
echo "Cyber has been removed successfully."
Execute the following command:
chmod +x cyber-remove.sh
./cyber-remove.sh
Frequently Asked Questions
1. After installation, an error message appears when running: cyber: command not found?
Please check whether /usr/bin is included in the current Linux environment variables. If not, please add it manually. First execute export PATH=$PATH:/usr/bin to add it to the current terminal session, and then execute cyber --help again to see if it is normal. This method is only valid in the current terminal session. If it needs to be permanent, please add export PATH=$PATH:/usr/bin to ~/.bashrc or ~/.zshrc (the shell configuration file you use), and then execute source ~/.bashrc or source ~/.zshrc to make it effective.
2. Unable to connect to the network after restarting the server
If it is configured according to the manual installation steps, cyber-core will not start automatically at boot. You need to manually execute cyber core start (or ensure that the systemd service in the system has been installed and used normally, and then execute cyber service install and cyber core enable to use the auto-start function at boot).
3. Security enhancement
If you are worried about encountering cross-domain attacks against the cyber core while surfing the Internet, you can run cyber config edit to modify the configuration file of the cyber core, and change the xxx part of external-controller: 127.0.0.1:xxx to any other number in the range of 1000-65535 (or run cyber config secret on), then restart cyber core via cyber core restart
