I have a Raspberry Pi 3 that I connected to a laptop and I am trying to control the Pi from my other laptop that has a Red Hat virtual machine installed. I have connected them using an ethernet cable and a USB cable using VNC viewer but all I can do is see the Pi's desktop.

Am I able to somehow control the Pi, for example running commands on it from the gnome terminal on my RedHat machine?

Thank you!

  • Please clarify "I have connected them together using an ethernet cable and an [sic] usb cable using VNC viewer but all I can do is see the Pi's interface on my desktop". Presumably you mean, "I have connected them together with an ethernet cable and a usb cable and I am trying to use VNC viewer but...". I.e., you are asking how to use VNC viewer? – goldilocks Sep 6 '17 at 12:27
  • Note the USB cable (picky tangent: that's a USB cable, because you-ess-bee does not start with a vowel, and writing follows speech in this case) is sort of irrelevant in that it is just for power BUT there is a good chance the port on your laptop will not provide sufficient power for a Pi 3. Is the red LED flickering at all? – goldilocks Sep 6 '17 at 12:28
  • OK, sorry, it's my first question and I'm new to all of this. – Simona Reti Sep 6 '17 at 12:31
  • I succeeded to connect them using VNC viewer but what I want is to control the pi from the gnome terminal on my RedHat machine. With VNC all I can do is see the PI's desktop – Simona Reti Sep 6 '17 at 12:32
  • For future reference if you are adding more information/clarifying the question, edit it into the question ;) You can then just leave a comment something like, "I've added the information to the question above". – goldilocks Sep 6 '17 at 12:45

If you mean you just want a remote command prompt, SSH is the standard tool (it will do graphical X forwarding too, but that is slightly more complicated).

To enable the server on a Pi using Raspbian, add a file named ssh to /boot (aka. the small first vfat partition) and reboot.

You then need to install the openssh client on the RedHat VM, if it is not there already. The command to connect is:

ssh pi@123.456.789

Where 123.456.789 is the appropriate IP address (if avahi is working, you may be able to use raspberry.pi). You will then be prompted for the pi user password. After that you should see the command prompt from the Pi.
