Agent Requirements

The agent will attempt to connect to your Knocknoc server using https on port 443/TCP. This could be on the Internet or internally within your own network. The package installation will automatically prompt you for the server hostname. You can reconfigure this in the config file (typically /opt/knocknoc-agent/etc/knocknoc-agent.conf) or by running configure-knocknoc-agent.

The agent is currently supported on the following platforms:

  • Debian 11 (Buster)
  • Debian 12 (Bookworm)
  • Ubuntu 23.10 (Mantic)
  • Ubuntu 22.04 (Jammy)
  • Ubuntu 20.04 (Focal)
  • Oracle Linux 8.x
  • Red Hat EL7+
  • CentOS 7+
  • Other Red Hat derivatives like Rocky and Oracle Linux
  • Microsoft Windows
  • Debian ARM64 (e.g. Raspberry Pi)
  • Docker on amd64 Linux

We are in the process of working on support for:

  • MacOS
  • Docker on arm64 Linux
