Unable to login at particular site using ssh

Dear sir/ma’am,

I am trying to do the first experiment in 2.3 Connected objects section. I have done upto uploading the firmware but when tried to ssh at particular site to run the nc command it gives me following error.

ssh fun4347838c5d@grenoble.iot-lab.info
fun4347838c5d@grenoble.iot-lab.info: Permission denied (publickey).

Do I have to generate the new public key for my account?

Regards,
Vishal

This issue is due to the modifications you did and reported in your post Regarding what to do in TP1?
I’ll answer in the latter to help you.

Otherwise, you should not use the login value to specify the username fot the ssh command, but rather use the environment variable setup to ease all commands, and already written for you in notebooks, thus you just have to copy/paste it:

ssh $IOTLAB_LOGIN@grenoble.iot-lab.info
