Configuring the PCoIP Software Client for Linux

The Software Client for Linux provides a number of configurable settings and behaviors, which allow the setting of user options, performance modes, and triggering actions like automated connections. These settings are not persistent and cannot be set via the user interface; they are set by launching the application using one of the methods described next.

To configure a client instance, you must launch it using one of these methods:

  • On the command line, with configuration values passed inline as flags, or
  • Via a URI, providing your configuration values in an encoded JWT string.

Setting Configuration Values on the Command Line

To set configuration values this way, launch the Software Client for Linux from a command prompt, and include the required options as flags. Multiple flags can be included in the same line. Use the following conventions when setting these parameters:

Type Format
Boolean No value is required; the flag implies "True"
Numeric Provide the parameter and then the numeric value, separated by a space.
String Provide the parameter and then the string value, separated by a space.
Values can be wrapped in double quotation marks if they contain spaces.

The following example launches the client in full-screen mode, sets log level 3, and points to a connection broker at broker.domain.com (if your application is installed somewhere else, use your own path instead):

/usr/bin/pcoip_client --connection-broker  broker.domain.com --log-level 3 --full-screen

The available settings are shown below.

Setting Configuration Values via a URI

Using this method, the Software Client for Linux is launched using a URI with configuration options (and, optionally, connection credentials) encoded in a JWT token string.

To use this method, create a URI with the following structure:

pcoip://[broker]/connect[?data={jwt}]

Where each segment shown above is:

Segment Description
pcoip:// Required. This scheme is registered with the operating system and will launch the Software Client for Linux.
broker Optional. FQDN of the connection broker to use. If the connection is not brokered, this can be omitted.
/connect Required. Requests a connection with the parameters defined in "?data"
?data={jwt} Optional. The string indicated by {jwt} here is a JWT payload, containing any required configuration settings and connection credentials. If all you want to do is launch the client with no options set, this can be omitted.

The JWT payload can contain both credential information and client configuration. To create the JWT payload:

  1. Create your configuration and credentials as a JSON object, using available configuration parameters and authentication credentials.
  2. Encode the object as a JWT token.
  3. Pass the token through the URI as the data parameter.

For example, the following JSON object would launch the client in full-screen mode, with log level 3:

{
    "fullscreen":true,
    "log-level":3
}

Encoded, and pointing to a connection broker at broker.domain.com, this would result in a URI similar to the following:

pcoip://broker.domain.com/connect?data=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJmdWxsc2NyZWVuIjp0cnVlLCJsb2ctbGV2ZWwiOjN9.3MRUQ4VeKHbCnkG4OIXsUYp2N1IGf6AzTIo8tnFoXoA

The available settings are shown below.
