CentOS 8.x Install nomachine

Note that if you are using bridged connection then gnome remote desktop sharing option may not get enabled as networks do not get detected as reported for Ubuntu OS at https://askubuntu.com/questions/1070520/screen-sharing-no-network-selected-for-sharing-problem-in-unity-control-center In such cases it is better to use nomachine which works properly on low bandwidth links and also works properly with wayland without requiring to switch to Xorg

To connect two CentOS 8.x systems using nomachine use following on both machines:

1. Download latest nomachine rpm from nomachine site - https://www.nomachine.com/download/
2. Install downloaded rpm using dnf

   dnf install nomachine*.rpm

3. Check status of nomachine server

   systemctl status nxserver

4. Enable copy-paste across machines using CentOS 8.x nomachine enable clipboard

After this you can open nomachine GUI client on source machine and try to connect to target over nx protocol

Optional Firewall changes

On nomachine 7.0 this was seen to happen automatically. But for older versions you can use:

1. Update firewalld settings on both machines

   firewall-cmd --add-port=4000/tcp --add-port=4011-4999/udp --permanent
   firewall-cmd --reload

   Not doing this on client machine may lead to empty display
