Users can login in Merlin through a Linux Remote Desktop Session. NoMachine is a desktop virtualization tool. It is similar to VNC, Remote Desktop, etc. It uses the NX protocol to enable a graphical login to remote servers.
Installation
NoMachine is available for PSI Windows computers in the Software Kiosk under the name NX Client. Please use the latest version (at least 6.0). For MacOS and Linux, the NoMachine client can be downloaded from https://www.nomachine.com/.

Accessing Merlin6 NoMachine from outside PSI
No VPN access
Access to the Merlin6 NoMachine service is possible without VPN through 'rem-acc.psi.ch'. Please follow the steps described in PSI Remote Interactive Access for remote access to the Merlin6 NoMachine services. Once logged in 'rem-acc.psi.ch', you must then login to one of the available MErlin6 NoMachine services.
VPN access
Remote access is also possible through VPN, however, you must not use 'rem-acc.psi.ch', and you have to connect directly to the Merlin6 NoMachine services as if you were inside PSI. For VPN access, you should request it to the IT department by opening a PSI Service Now ticket: VPN Access (PSI employees).
