labgrid-exporter --help

labgrid-exporter *.yaml


Labgrid is a scalable infrastructure and test architecture for embedded (linux) systems.

This is the man page for the exporter, supporting the export of serial ports, USB devices and various other controllers.


-h, --help display command line help
-x, --crossbar-url
 the crossbar url of the coordinator
-i, --isolated enable isolated mode (always request SSH forwards)
-n, --name the public name of the exporter
--hostname hostname (or IP) published for accessing resources

-i / –isolated

This option enables isolated mode, which causes all exported resources marked as requiring SSH connection forwarding. Isolated mode is useful when resources (such as NetworkSerialPorts) are not directly accessible from the clients. The client will then use SSH to create a port forward to the resource when needed.

-n / –name

This option is used to configure the exporter name under which resources are registered with the coordinator, which is useful when running multiple exporters on the same host. It defaults to the system hostname.


For resources like USBSerialPort, USBGenericExport or USBSigrokExport, the exporter needs to provide a host name to set the exported value of the “host” key. If the system hostname is not resolvable via DNS, this option can be used to override this default with another name (or an IP address).


The exporter uses a YAML configuration file which defines groups of releated resources. Furthermore the exporter can start helper binaries such as ser2net to export local serial ports over the network.


The following environment variable can be used to configure labgrid-exporter.


This variable can be used to set the default crossbar URL (instead of using the -x option).


This variable can be used to set the default crossbar realm to use instead of realm1.


Start the exporter with the configuration file my-config.yaml:

$ labgrid-exporter my-config.yaml

Same as above, but with name myname:

$ labgrid-exporter -n myname my-config.yaml
