# Using RStudio or Jupyter Notebook in Puhti
# Using RStudio or Jupyter Notebook on Roihu

[RStudio](https://www.rstudio.com/) and [Jupyter notebooks](https://jupyter.org/) are convenient options for developing and running R or Python code.
The R or Python code is run on a compute node within an [interactive session](../../computing/running/interactive-usage.md), but the tools themselves are used via a local web browser.

There are two ways to use RStudio Server or Jupyter Notebook on Puhti.

1. The first (and easiest) option is to use [the Puhti web interface](../../computing/webinterface/index.md).
1. The first (and easiest) option is to use [the Roihu web interface](../../computing/webinterface/index.md).

2. The second option is to create a SSH tunnel from a local PC to a compute node. As compute nodes are inaccessible via the Internet,
the tunnel needs to go through a login node. This is not possible with Windows PowerShell (it does not support jump servers), and therefore it is
not suitable for RStudio or Jupyter Notebook in Puhti.
not suitable for RStudio or Jupyter Notebook in Roihu.
SSH tunneling requires that you have [set up SSH keys](../../computing/connecting/ssh-keys.md).

With Linux, macOS and MobaXterm the SSH tunnelling works by default. PuTTy requires filling in the settings to PuTTy tabs, so it is slower and more complicated, but possible.

**Using SSH tunneling**

!!! note
SSH tunnelling is not yet enabled on Roihu. The instructions below refer to using it on Puhti.

* Start interactive session
* Load suitable modules and start RStudio or Jupyter Notebook server
* Create SSH tunnel from your PC to Puhti compute node
