I have a bare minimal Debian 8.6 installation on a remote server where I need to keep the OS as uncluttered as possible and I don't need any local desktop environment. However I need to forward X11 via ssh.
The X11 forwarding is enabled in /etc/ssh/sshd_config as follows:
X11Forwarding yes
X11DisplayOffset 10
and the ssh daemon has been restarted after modifying the configuration file.
From the ssh debug messages I see that the X11 forwarding request is accepted and no particular error is shown. As a result on the remote server the DISPLAY environment variable is correctly initialized to localhost:10.0.
However when I try to run xeyes, although no errors are shown on the terminal, I don't see anything appearing on my local machine (Debian stretch). But the local machine is not a problem since I can successfully forward X11 from other servers.
It is not a firewall issue since it does not work even after flushing all iptables rules.
Below you can find the list of installed packages. What am I missing? Are there X11 related packages that I can remove?
Thank you,
Davide
