Remote server

There is several tricks and nice features to know when dealing with ssh and remote servers.

Let’s suppose that you want to access the grenoble server through ssh. It would be really easy to type just ssh grenoble for instance and get it working. Good news, ssh can do that! Just write in your ~/.ssh/config the following snippet:

Host grenoble
HostName grenoble.iot-lab.info
User leone

Don’t forget to replace leone with your real user name ;-) Then simply do a ssh-copy-id grenoble enter your password and you are all set!

Next you can connect to the server in Grenoble by simply typing ssh grenoble.

An other feature is that it allows to simplify the fabric file. For instance let’s suppose that you want to download all the content of a precise folder on your local machine. You can use snippet in your fabric file such as:

from fabric.api import env
env.use_ssh_config = True

@task
@hosts("grenoble")
def push(name):
    path = pj(EXPERIMENT_FOLDER, name)
    put(path,
        remote_path="~/html/results/")
