## SSH Access
For interactive command shell access, use an SSH client. We recommend to activate SSH's X11 forwarding to allow you to use graphical
applications (e.g. a text editor, but for more performant graphical access, refer to the sections below). X applications are supported
in the login nodes and X11 forwarding can be used for those users who have properly configured X11 support in their desktops, however:
* Merlin6 administrators **do not offer support** for user desktop configuration (Windows, MacOS, Linux).
* Hence, Merlin6 administrators **do not offer official support** for X11 client setup.
* Nevertheless, a generic guide for X11 client setup (*Linux*, *Windows* and *MacOS*) is provided below.
* PSI desktop configuration issues must be addressed through **[PSI Service Now](https://psi.service-now.com/psisp)** as an *Incident Request*.
* Ticket will be redirected to the corresponding Desktop support group (Windows, Linux).
### Accessing from a Linux client
Refer to [{How To Use Merlin -> Accessing from Linux Clients}](/merlin6/connect-from-linux.html) for **Linux** SSH client and X11 configuration.
### Accessing from a Windows client
Refer to [{How To Use Merlin -> Accessing from Windows Clients}](/merlin6/connect-from-windows.html) for **Windows** SSH client and X11 configuration.
### Accessing from a MacOS client
Refer to [{How To Use Merlin -> Accessing from MacOS Clients}](/merlin6/connect-from-macos.html) for **MacOS** SSH client and X11 configuration.
## NoMachine Remote Desktop Access
X applications are supported in the login nodes and can run efficiently through a **NoMachine** client. This is the officially supported way to run more demanding X applications on Merlin6.
* For PSI Windows workstations, this can be installed from the Software Kiosk as 'NX Client'. If you have difficulties installing, please request support through **[PSI Service Now](https://psi.service-now.com/psisp)** as an *Incident Request*.
* For other workstations The client software can be downloaded from the [Nomachine Website](https://www.nomachine.com/product&p=NoMachine%20Enterprise%20Client).
### Configuring NoMachine
Refer to [{How To Use Merlin -> Remote Desktop Access}](/merlin6/nomachine.html) for further instructions of how to configure the NoMachine client and how to access it from PSI and from outside PSI.
## Login nodes hardware description
The Merlin6 login nodes are the official machines for accessing the recources of Merlin6.
From these machines, users can submit jobs to the Slurm batch system as well as visualize or compile their software.
The Merlin6 login nodes are the following:
| Hostname | SSH | NoMachine | #cores | #Threads | CPU | Memory | Scratch | Scratch Mountpoint |
| ------------------- | --- | --------- | ------ |:--------:| :-------------------- | ------ | ---------- | :------------------ |
| merlin-l-001.psi.ch | yes | yes | 2 x 22 | 2 | Intel Xeon Gold 6152 | 384GB | 1.8TB NVMe | ``/scratch`` |
| merlin-l-002.psi.ch | yes | yes | 2 x 22 | 2 | Intel Xeon Gold 6142 | 384GB | 1.8TB NVMe | ``/scratch`` |
