connect to an remote kernel

[Serge Scevenels]

Hi,

I would like to know how can i connect Spyder to an ipython kernel active on a vagrant VMs. 

I'd like to know what kind of config I should introduce as connection info, ssh key, etc...

Maybe it is not yet supported. If it is the case, please let me know :)

Thks,

Serge

Have not gone all the way through the below, but it would seem to cover
what you are asking:

Hi Serge,

Since Spyder 2.3.1 this is very easy, using ssh. You need to go to the menu

    Consoles > Connect to an existing kernel

and introduce the information about your remote kernel (i.e. ip address, remote user name, etc).

One important thing to consider is that you need to ssh first to your remote machine using a regular terminal (i.e. outside Spyder), to avoid a lock while waiting for the connection confirmation.

If you have any further doubts, please feel free to post them here :-)


Cheers,
Carlos

Hi Carlos,

thanks for the reply. 

I managed to connect to the remote kernel !! I did it this way, and then I'll ask you if it can be simpler :)

1. on the VM, I start a kernel with port set using the following command line:

ipython kernel --profile=spyder --ip 0.0.0.0 --control=11111 --shell=22222 --iopub=55555 --hb=33333 --stdin=44444 --ipython-dir=/home/vagrant/.ipython -f /vagrant/.ipython-kernel.json

2. i configured on the VM the corresponding forwarded port

3. in Spyder, I select connect to an existing kernel and I provide :

  a. the json file located on the shared folder

  b. I provide the <user>@<ip guest>:<port> to connect to the machine via SSH

  c. I provide the password

This is working great. I have been able to automatise step 1 and 2 easily, so that I don't need to repeat these steps everytime I turn on my VM. However, evertime I start spyder on the host machine, I'll need to re-do step 3. Is there a way to automatize it at spyder start ?

Thks,

Serge

Hi all,

can somebody help me with this latest problem I am having :)

Can it be resolved by using a custom PYTHONSTARTUP script ? If it is the case, can i have some hint :)

You can simplify some of 3) b&c by using ssh config and public key
connections:

Here is a SO answer that may help with a startup file:

Just found this:

http://ipython.org/ipython-doc/dev/config/options/qtconsole.html?highlight=sshserver

IPythonQtConsoleApp.sshkey : Unicode

Default: ‘’

Path to the ssh key to use for logging in to the ssh server.
IPythonQtConsoleApp.sshserver : Unicode

Default: ‘’

The SSH server to use to connect to the kernel.

A way of configuring your profile to work with SSH.

Hi,

I'm trying to connect my Windows Spyder IDE to an Ubuntu ipython kernel - I read that from Windows this feature is error-prone. Should it definitely be possible?

Thanks
