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/.
## Access restrictions
Currently, NoMachine access is only possible from the PSI Network. Users needing
remote access from outside PSI must request VPN access. This has to be requested
to the IT Department by opening a PSI Service Now ticket:

## 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](https://www.psi.ch/en/photon-science-data-services/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:

## Transferring Data to/from outside PSI

Two servers are enabled for exporting data from Merlin to outside PSI.
These Remote Access Merlin servers are the following:
* **'ra-merlin-01.psi.ch'**
* **'ra-merlin-02.psi.ch'**
Due to security reasons, currently only ``/data/user`` directories are exported in Read-Only mode.
This policy will change in the future but in the meantime we allow users to export their files
in an easy way.
{{site.data.alerts.warning}}Please, <b>ensure proper secured permissions</b>. By default,
when directory is created, the system applies the most restrictive permissions. However,
this does not prevent users for changing permissions if they wish. At this point, users
become responsible of those changes.
{{site.data.alerts.end}}
Transferring big amounts of data from outside PSI to Merlin is not possible yet, unless
this is done from PSI (i.e. transferring files from CSCS to Merlin is possible by using
`scp` / `rsync` commands from the Merlin6 login nodes).
### Accepted protocols
Accepted protocols for Remote Access Merlin servers are the following:
* **sftp**: **``sftp``** command or similar X11/Windows/MacOS based programs.
* **ssh**: **`scp`** command (as well as **WinSCP** and similar programs) or **`rsync`** command
* **~~Globus Online~~**: ***not available yet.***
### About Remote Access Servers
SSH is one of the allowed protocols.
* Please, **absolutely never** use this servers as a login node.
* Please avoid copying files to the *home* directories.
Only ``/data/user`` should be used on these nodes, and exclusively for transferring data to outside PSI.
## Connecting to Merlin6 from outside PSI
Merlin6 is fully accessible from within the PSI network. To connect from outside you can use:
- [VPN](https://www.psi.ch/en/computing/vpn) ([alternate instructions](https://intranet.psi.ch/BIO/ComputingVPN))
- [SSH hop](https://www.psi.ch/en/computing/ssh-hop)
* Please avoid transferring big amount data through **hop**
- [No Machine](nomachine.md)
* Remote Interactive Access through [**'rem-acc.psi.ch'**](https://www.psi.ch/en/photon-science-data-services/remote-interactive-access)
* Please avoid transferring big amount of data through **NoMachine**
