In this recording I am installing x2go server onto a Centos 7 vm and then am connecting to it with the x2go client from a Windows 10 vm. The connection is through a VPN, so that a remote access setup can be demonstrated. Below are some of the commands that I use to perform the setup. I also have to download puttygen to set up and copy the SSH public key from the Windows 10 machine, to the VPN/X2Go server.

yum install epel-release
yum install x2goserver x2goserver-xsession fuse-sshfs
yum groupinstall "Desktop" "Desktop Platform" "X Window System" "Fonts" "Graphical Administration Tools" "Internet Browser"
yum groupinstall "MATE Desktop"
iptables -F
iptables -X
useradd user
passwd user
/usr/sbin/sshd -p 4444 -o "PasswordAuthentication no" -o "PermitRootLogin no" -o "GSSAPIAuthentication no"
