Hello!
I would like to help you with this task.
I suggest you to use RealVNC to connect to users' sessions and monitor them.
it works great, I use it a lot on my servers to connect to users and support them.
About my experience: I have big experience with network administration (VLAN, SNAT, DNAT, iptables, iproute2, multiWAN, tcpdump...). Big experience with OpenVPN servers/clients. Serial connection 2,3 servers for more security. OpenVPN over IPv6 and other.... Experience with VMWare ESXi, MS Hyper-V, Proxmox VE, Mikrotik, Ubiquiti and some different skills.
My other skills and reviews you can see in my profile.
Hope for cooperation!
Thank you!
