IoT-LAB testbed ssh command-line client
Project description
SSH CLI Tools provides a set of commands for interacting remotely and easily with IoT-Lab Linux nodes. See here to get more information on this kind of node.
All available actions provided by SSH CLI Tools are available as sub-commands of iotlab-ssh.
The provided sub-commands are:
Sub-command |
Function |
|---|---|
flash |
Flash the given firmware on the nodes co-microcontroller |
reset |
Reset the nodes co-microcontroller |
wait-for-boot |
Block the execution until all nodes have booted or maximum wait time has expired |
run-script |
Run a given script in background (screen session) on the given nodes |
run-cmd |
Run a command on the given nodes |
copy-file |
Copy a file on SSH frontend homedir directory (~/shared/.iotlabsshcli) |
SSH CLI Tools can be used in conjunction with the IoT-Lab CLI Tools commands like iotlab-auth and iotlab-experiment.
Installation:
You need python pip. To do a system-wide install of the ssh-cli-tools use pip (or pip3 for Python 3):
$ sudo pip install iotlabsshcli
Pip version >= 9.0 is known to work ; you may need to upgrade. See INSTALLING.md for details on installation options.
Requirements:
Linux nodes are reachable through a gateway SSH server (IoT-LAB SSH frontend). For this reason you must verify that your SSH public key used by ssh-cli-tools has been recorded in your IoT-LAB user profile. You can find how to configure your IoT-LAB SSH access in this documentation.
Examples:
Start an experiment, wait for it to be ready, wait for all nodes boot:
$ iotlab-experiment submit -d 120 -l saclay,a8,1-10
{
"id": 65535
}
$ iotlab-experiment wait
Waiting that experiment 65535 gets in state Running
"Running"
$ iotlab-ssh wait-for-boot
{
"wait-for-boot": {
"0": [
"node-a8-2.saclay.iot-lab.info",
"node-a8-3.saclay.iot-lab.info",
"node-a8-5.saclay.iot-lab.info",
"node-a8-6.saclay.iot-lab.info",
"node-a8-7.saclay.iot-lab.info",
"node-a8-9.saclay.iot-lab.info",
"node-a8-10.saclay.iot-lab.info"
],
"1": [
"node-a8-4.saclay.iot-lab.info",
"node-a8-8.saclay.iot-lab.info"
]
}
}Note: node-a8-4 and node-a8-8 are broken in Saclay.
Flash a firmware on the co-microcontroller of the working nodes:
$ iotlab-ssh flash <firmware.elf> -l saclay,a8,2-3+5-7+9-10
{
"flash": {
"0": [
"node-a8-2.saclay.iot-lab.info",
"node-a8-3.saclay.iot-lab.info",
"node-a8-5.saclay.iot-lab.info",
"node-a8-6.saclay.iot-lab.info",
"node-a8-7.saclay.iot-lab.info",
"node-a8-9.saclay.iot-lab.info",
"node-a8-10.saclay.iot-lab.info"
]
}
}Reset the co-microcontroller of one node:
$ iotlab-ssh reset -l saclay,a8,2
{
"reset": {
"0": [
"node-a8-2.saclay.iot-lab.info"
]
}
}Use the –verbose option to get the commands output:
$ iotlab-ssh --verbose reset -l saclay,a8,2

}Note: a screen session is launched on the node to actually run the script and provide easy access to outputs if needed. When the script ends, the screen session is terminated and the logs are gone.
root@node-a8-2:~# screen -ls
There is a screen on:
