However, during SSH port forwarding, the data transmitted can be a binary stream of protocol tunneled over SSH (e.g. For example, during shell access, the data transmitted are binary streams detailing dimensions of pseudo-terminal and ASCII characters to run commands on the remote shell. But the data transported within the SSH session can be of any type. Under the hood, your SSH client creates an encrypted session between your SSH client and the SSH server. This is the default behavior of an SSH connection. When you connect to a server using SSH, you get a server's shell. SSH tunneling helps achieve security use cases such as remote web service access without exposing port on the internet, accessing server behind NAT, exposing local port to the internet. SSH tunneling is a method to transport additional data streams within an existing SSH session. If you are looking for a modern open-source alternative to OpenSSH that is optimized for elastic multi-cloud environments and supports other access protocols in addition to SSH, make sure to check out Teleport. It comes pre-installed by default with the vast majority of Linux distributions. OpenSSH is the most widely used open-source SSH server. In this post, I'll cover different tunneling features as supported by OpenSSH, which helps achieve security use cases such as remote web service access without exposing ports on the internet, accessing servers behind NAT, exposing local ports to the internet.

And this is just a small set of what's possible with SSH. The solution is to open the browser locally, and to route the traffic between the browser and the jupyter notebook server running on deeplearning, through portal.Although the typical use case of SSH is to access a remote server securely, you can also transfer files, forward local and remote ports, mount remote directories, redirect GUI, or even proxy arbitrary traffic (need I say SSH is awesome?). If your local network connection is slow, the browser will feel slow and unresponsive.

These incompatibilities make the remote graphics applications sluggish even on very fast networks. And that's clearly the case here since we want to make use of nvidia GeForce GPUs for deep learning.

If local runs macOS, there are incompatibilities between the X11 on deeplearning and the one on the mac, when nvidia drivers are used on deeplearning. This does work because we used ssh with the -X option, which enables X11 forwarding, and thus makes it possible to open graphics application remotely.

This opens a browser on deeplearning, and displays the browser window on local. In this situation, what most physicists would do is the following:Ĭonnect from the local to portal with ssh -XĬonnect from the portal to deeplearning with ssh -X That's a fairly typical configuration in research labs and companies. Portal is on the lab network, and is also visible from outside. This machine is inside the lab network and is not accessible from outside, but I have ssh access to it from inside. The computers involved are the following:ĭeeplearning is the deep learning station. I only try to find ways to do data science efficiently, and I hope I can help you with that as well. Therefore, the terminology I'm using may be incorrect. Afterwards, you'll need only a couple seconds to set up the connection with your remote jupyter notebooks.īefore we get started, please keep in mind that I'm just a physicist with limited knowledge of networking. It might take you 10 minutes to set everything up the first time, but it's worth it. Start a jupyter notebook server on this machineĬonnect to this server from a browser running on your local machine to create and use jupyter notebooks In this post, I'd like to show how I proceed to create and use jupyter notebooks on a remote machine.Ĭreate an ssh tunnel to a remote machine behind a firewall Still, quite often, I either don't have time to commute to the lab and just work from home, or I'm at CERN, 200 kms away.

Unfortunately, it's behind a firewall and is not directly accessible from outside. It's quite nice, with 20 cores, 64 GB RAM, a large amount of SSD disk space for my data, and most importantly two GeForce GTX 1080 Ti. I've got a linux machine dedicated to deep learning development in my lab.
