Install openssh on both machines.
2 steps: Setting up the ssh server, then forwarding X.
Client refers to the other machines, and server refers to the Manjaro machine.
Setting up the ssh server
- Check sshd (the server process) is running with
pgrep sshd (Will output nothing if sshd isn't running).
- Ensure you have either a very strong password, or disable password authentication and use key forwarding by editing
/etc/ssh/sshd_config and changing
PasswordAuthentication yes to
PasswordAuthentication no, then
sudo restart ssh.
- Ensure you can log into the server from the client via ssh.
Follow the instructions in this answer. Copied here:
"On the client side, the
-X (capital X) option to
ssh enables X11 forwarding, and you can make this the default (for all connections or for a specific conection) with
ForwardX11 yes in
On the server side,
X11Forwarding yes must specified in
/etc/ssh/sshd_config. Note that the default is no forwarding (some distributions turn it on in their default
/etc/ssh/sshd_config), and that the user cannot override this setting.
xauth program must be installed on the server side. If there are any X11 programs there, it's very likely that
xauth will be there. In the unlikely case
xauth was installed in a nonstandard location, it can be called through
~/.ssh/rc (on the server!).
Note that you do not need to set any environment variables on the server.
XAUTHORITY will automatically be set to their proper values. If you run ssh and
DISPLAY is not set, it means ssh is not forwarding the X11 connection.
To confirm that ssh is forwarding X11, check for a line containing
Requesting X11 forwarding in the
ssh -v -X output. Note that the server won't reply either way, a security precaution of hiding details from potential attackers."
Make sure you restart sshd after changing settings to
cat /var/run/sshd.pid | xargs kill -1
