How should I cite R2lab in my paper?

If you are using R2lab for in your publications, please add the following text in the Acknowledgment section of your papers/reports:

We would like to thank the FIT R2lab team from Inria, Sophia Antipolis, for their help in using the FIT-R2lab testbed (\url{https://fit-r2lab.inria.fr/}) [Ref-R2lab].

nepi-ng or apssh won't find my ssh key

The simplest answer is, make sure to add the relevant ssh key in your ssh agent.

How can I send noise on a WiFi or 5G frequency

It is easy to do that from any node that has a USRP attached.

You will need gnuradio's uhd_siggen utility; this is among others shiped in our gnuradio image - see the manual page for details.

How do I use the data wired interface

The standard images do turn on the control wired interface at boot-time (of course, otherwise we could not reach them), but OTOH they do not manage the data interface at all.

You can use the convenience function

turn-on-data

that will use DHCP to configure your data interface; it will in this case be reachable from the gateway or from other nodes as hostname e.g. data27.

Important note

The nodes that have a USRP attached of type n210 or usrp2 cannot use the data interface (see below).

How do I initialize a USRP device connected through Ethernet

We have just seen that nodes that have a USRP attached of type n210 or usrp2 cannot use the data interface as the physical interface is actually used to connect to the USRP device instead.

On these nodes you need to initialize the connexion between node and USRP using this convenience function:

enable-usrp-ethernet

How do I initialize a USRP device connected through USB

From the node itself

usrp-reset

From faraday

You can use the usual rhubarbe selection mechanism, like .e.g

rhubarbe usrpoff 1-5,10
rhubarbe usrpoff 1-5,10

Or shorter

uoff 1-11-2
uon 1-11-2
