Using the Serial Console

Determining which nodes to connect to

You can determine the nodes allocated to your experiment by looking at the Reserved Nodes table on the Show Experiment page on the web interface. The node names will be given in the first column of the table.

Connecting to the Serial Console

Every node on the testbed has serial console access enabled.

To connect to a node's serial console, you must first log into and use the /usr/testbed/bin/console command.

To connect to a particular node, type /usr/testbed/bin/console node-name where node-name is a node allocated to your experiment.

To disconnect from the console session, press Ctrl key and ']' key together, then type quit.

Serial Console Logs

All console output from each node is saved in /var/log/tiplogs/, where node-name is a node allocated to your experiment.

This run file is created when nodes are first allocated to an experiment, and the Unix permissions of the run files permit only members of the project to view them.


When the experiment is swapped out, the run logs are removed. In order to preserve them, you must make a copy before swapping out your experiment.

Console logs may be viewed through the web interface on the Show Experiment page by clicking on the icon in the Console column of the Reserved Nodes table.
