Linux

The Linux agent allows the inclusion of devices with this operating system in the service consoles, enabling support teams to have complete visibility of all devices in use within the organization.

Linux support includes distributions like Fedora, Debian, and its derivative, Ubuntu. Both physical and virtual devices on VMware as a hypervisor and VDIs published with Citrix as a broker are supported.

FlexxAgent is composed of a process of the same name, which runs at the system level and obtains all device information: its consumption metrics, performance, and all information visible in the consoles related to the device.

FlexxAgent-Session initiates an instance for each user session on the device. It gathers information about the session, such as the applications in use and their consumption, system resource usage by the session, and session delivery times.

Supported versions

Currently, FlexxAgent officially supports the following distributions and versions:

• Fedora 37 or later
• Debian/GNU Linux 11 (bullseye) or later
• Ubuntu 22.04, 24.04

More distributions are regularly validated.

To include a distribution in the list of supported distributions, please contact Flexxible.

Requirements

Before installing, updating all system packages is recommended. The necessary components will be installed, depending on the distribution.

Package dependencies for Fedora and Debian:

• dmidecode
• imvirt
• systemd

Limitations

Certain functionalities are unavailable for Linux, such as remote assistance, user microservices, flow execution, the collection of plug-and-play peripheral data, and proxy use.

The on-demand execution of microservices from Workspaces supports Bash as a scripting language.

Proxy Configuration

FlexxAgent for Linux supports communication via authenticated and unauthenticated proxy; proxy information must be provided to Flexxible to include it in the configuration file mentioned in the next point.

Required data:

• For unauthenticated proxy, it is necessary to provide URL and Port
• For authenticated proxy, User and password must be added to the above

Download and installation

To install FlexxAgent, you must run the installation script using a preset configuration file.

Installation Scripts

Path to download the installation script on Ubuntu/Debian:

https://update.workspaces.flexxible.com/agents/FlexxAgent/latest/debian/x64/flexxagent-install.sh

Path to download the installation script on Fedora:

https://update.workspaces.flexxible.com/agents/FlexxAgent/latest/fedora/x64/flexxagent-install.sh

   sudo chmod +x ./flexxagent-install.sh

3. Run the script.

   sudo ./flexxagent-install.sh -c [configuration file]

4. Clean the files used.

Installation script parameters

Parameter	Caption
-v,--version <VERSION>	Use a specific version, by default latest.
-d,--distro <DISTRO>	The script automatically detects the DISTRO in use on the system it is running on. This parameter helps force the FlexxAgent version installation for a specific DISTRO when working with derived or similar distros.
--verbose,-Verbose	Displays diagnostic information.
-c,--config <CONFFILE>	Applies the configuration from a configuration file by default, settings.conf.
-?,--?,-h,--help,-Help	Shows help.

Examples

Install FlexxAgent with the configuration file:

flexxagent-install.sh [-c|--config <path/file.conf>]

Install a specific version of FlexxAgent:

flexxagent-install.sh [-v|--version <VERSION>]

Force the FlexxAgent installation for a specific distribution:

flexxagent-install.sh [-d|--distro <DISTRO>]

Access the help:

flexxagent-install.sh -h|-?|--help

Uninstall

The uninstallation script can be downloaded from

https://update.workspaces.flexxible.com/agents/Linux/FlexxAgent/latest/flexxagent-uninstall.sh

Steps for uninstallation:

1. Download the uninstaller from the URL.

2. Grant permissions to the script.

   sudo chmod +x ./flexxagent-uninstall.sh

3. Run the script.

   sudo ./flexxagent-uninstall.sh

4. Clean the files used.

Uninstallation script parameters

Parameter	Caption
-d,--distro <DISTRO>	The script automatically detects the DISTRO in use on the system it is running on. This parameter helps force the FlexxAgent version uninstallation for a specific DISTRO when working with derived or similar distros.
-c,--cleanup <VERSION>	Cleans configurations and logs; default is false.
-?,--?,-h,--help,-Help	Shows help.

Examples

Uninstall and clean up configurations and logs:

flexxagent-uninstall.sh [-c|--cleanup]

Force the uninstallation for a DISTRO:

flexxagent-uninstall.sh [-d|--distro <DISTRO>]

Access the help:

sudo ./flexxagent-uninstall.sh --help

Update

There are two ways to update FlexxAgent to its latest version:

• From Workspaces, select the device and perform: Operations -> FlexxAgent -> Update to the latest version.
• Re-running the installation script to download and install the latest version.

Obtained fields

FlexxAgent obtains and sends the following general information to the consoles:

• Name: device name
• Device Status: on or off
• Version: FlexxAgent version
• FlexxAgent Status: running or stopped
• Last FlexxAgent report: date and time of last report received
• Connection: Wireless LAN, mobile network, ethernet, unknown
• Network: device network addressing and public IP for internet access. These networks are created automatically when more than four workspaces are connected to the same network.
• Subnet: device network segment
• MAC address
• Wireless network: network name
• Network signal: reception percentage
• Network changes: last time the network changed
• Sessions: number of user sessions
• Last User: last user who logged in
• Connected From: name of the device from which the user has logged in
• Connection time: session start date and time
• Code: this field lets users identify the workspace with a personal code. This code must be manually filled in individually using the Edit option in the Operations menu of the workspace details.
• RAM: total available RAM capacity
• Cores: number of processor cores
• IP address: device IP address on the local network
• OS: operating system name
• Operating system: operating system version
• System disk: total disk capacity and usage in percentage

At the detailed information level in the device view in Workspaces, it includes:

• List of sessions with each session's resource consumption details (CPU/RAM)
• List of workspace disks with occupied space
• Graphic performance counters for CPU, RAM, bandwidth, and wireless connection signal

The Analyzer module receives general device data, as well as information about CPU and RAM consumption, installed applications, and also running processes and applications.
