Command line tools

This page introduces how to use LibCyber's command line tool cyber.

Install

The latest version: v1.2.1

reminder

It is recommended to install it under the root user (non-sudo) under 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)

reminder

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.

# Download

Long story short

# 1. Get proxy configuration instructions.

# 2. Copy the output result of the above command and execute it.
# export http_proxy=http://127.0.0.1:8890;export https_proxy=http://127.0.0.1:8890;export all_proxy=socks5://127.0.0.1:8891

# 3. Use curl, wget and other commands to test whether the proxy is effective.

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

common problem

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 enableuses 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 the range of 1000-65535 any other number (or run cyber config secret on), then restart cyber core via cyber core restart
