Installing an Agent

Rumble requires the use of at least one Agent within your environment to enable network discovery. The agent should be installed on a system with reliable connectivity to the network you want to discover. For internal networks, Rumble works best when installed on a system with a wired (vs wireless) connection. For external network discovery, nearly any cloud provider with a reliable connection should do. If the Rumble agent is installed in a container or virtualized system, ensure that it has direct access to the network (host networking in docker, bridged networking in VMWare, etc).

To install the Rumble agent, login to the Rumble Console and switch to the Organization that should be associated with the agent. The agent download link is specific to your active Organization and using the wrong link can result a new agent being associated with the wrong Organization.

Download the correct binary for your system from the agent download page. For most systems, select the 64-bit (x86_64) architecture. For embedded devices, such as the RaspBerry Pi 3+, choose the ARM7 architecture. Windows binaries are signed with a valid Authenticode signature, which should be validated before the executable is launched.

The agent installation process requires administrative privileges. On Windows, a UAC prompt may be displayed. On Linux and macOS the downloaded binary should be made executable (chmod u+x rumble-agent.bin) and then executed with root privileges (sudo or from root shell). In either case, the agent should install itself as a system service and start immediately, displaying a new entry in the agents page.

System Requirements

  • Windows Server 2012 R2+ or Windows 10 Build 1604+
  • Processor running at 2.0Ghz or faster
  • At least 4Gb of memory (1Gb available)
  • At least 1Gb of free storage space

Windows Server 2008, Windows Server 2012, Windows 7, and Windows 8 may be able to run the agent in a pinch, but are not officially supported.

  • Kernel version 2.6.23 or later
  • Processor running at 2.0Ghz or faster
  • At least 2Gb of memory (1Gb available)
  • At least 1Gb of free storage space

Linux ARM devices with limited processing power and memory, such as the Raspberry Pi, can run the Rumble Agent, but may have trouble scanning larger networks.

  • macOS 10.10 (Yosemite) or newer
  • Processor running at 2.0Ghz or faster
  • At least 2Gb of memory (1Gb available)
  • At least 1Gb of free storage space
Web Screenshots

Google Chrome or Chromium should be installed on the Agent system to enable web screenshots.

Network Communication

The agent connects to the host on TCP port 443 using TLS. This connection is used for agent registration, data transmission, job scheduling, and status messages. For completely offline environments, the Rumble Scanner can be used to create scan data files that can be uploaded later via the Inventory Import action.

Please note that certain web proxies that perform TLS inspection do not handle Websocket communication properly and TLS inspection will need to be disabled for the Rumble agent to successfully connect. The most popular product with this problem is the Sophos (previously Cyberoam) security appliance.

Proxy support is handled automatically in most cases. On the Windows platform, proxy information is read from the registry keys (used by Chrome, Edge, and IE).

On Linux and macOS, the proxy can be configured by setting the HTTPS_PROXY environment variable in the Rumble Agent service wrapper. The value of the HTTPS_PROXY environment variable should be a fully-qualified URL (http://proxy:8080), a hostname and port (proxy:8080), or just a hostname (proxy).

Removing an Agent

The easiest way to remove an agent is to use the Agents page Manage menu and select the Uninstall Agent option. This will remove the service and terminate the current agent process. If you would like to remove the agent without using the Rumble Console, there are a couple options.

On the Windows platform, each agent will be listed in Programs and Features, and can be uninstalled like any other application.

On all platforms, including Windows, the agent can uninstall itself if run with the uninstall argument from a root or Administrator shell:


c:\Program Files\Rumble\rumble-agent-[oid].exe uninstall

Linux and macOS

# /opt/rumble/rumble-agent-[oid].bin uninstall
