Hello yt users, I have a (perhaps naive) ssh question related to the yt notebook. I would like to run a yt notebook server on machine A. However, machine A cannot be directly accessed via ssh from the wider internet. Instead, I must first ssh into machine B, and then ssh from B to A. Machine B cannot run the notebook server itself. Does anyone know how I can configure things - perhaps by using a more complicated ssh tunnel command - so I that access a notebook server running on machine A through machine B? Thanks, Andrew
I use this script to tunnel into a worker node on a cluster, it may be helpful. https://www.dropbox.com/s/joerbm32o109air/ipyn_polaris2.py Stuart On 23 Nov 2013 23:36, "Andrew Myers" <atmyers2@gmail.com> wrote:

Hi Stuart, Thanks a bunch for sharing that script! I was able to modify to do what I wanted. Best, Andrew On Sat, Nov 23, 2013 at 3:42 PM, Stuart Mumford <stuart@mumford.me.uk>wrote:

Hi John, Here it is. It's essentially the same as Stuart's, except that instead of asking the scheduler for a compute node, it chains multiple ssh commands together. This probably won't work if your machines are set up to prompt you for a password interactively. https://www.dropbox.com/s/qkmy756wwl5ylol/ipynb_hepburn.py -Andrew On Sun, Nov 24, 2013 at 5:57 PM, John ZuHone <jzuhone@gmail.com> wrote:

Here is a modified version of Stuart's original script that works with a torque/maui job scheduler: http://paste.yt-project.org/show/4540/ I've cleaned up and reorganized a bit and added a signal handler that ensures a job does not stay running on the cluster after we disconnect or if the script crashes for some reason. Hope it's useful for others, -Nathan On Mon, Nov 25, 2013 at 3:44 PM, Andrew Myers <atmyers2@gmail.com> wrote:
