Running Jupyter on Bluemix virtual machine

I have set up a virtual machine on Bluemix. I want to set up Jupyter Notebooks on it. I followed the tutorial here how to set up Jupyter on a VM. http://blog.impiyush.me/2015/02/running-ipython-notebook-server-on-aws.html

It all worked until I got the below, when I try to connect to the below address, entering the public IP like https//:xxx.xxx.xx.xx:8888/ I get message unable to connect.

VM is Ubuntu 14.04. In setting up the VM, I could only select Security Groups: default , and network Private.

Any ideas what the issue may be ?

Solution

  • Short answer is to disable firewall in your Ubuntu server:

    $ sudo ufw disable

    Now a more detailed explanation and alternative solution.

    The default security group for VMs deployed in the Bluemix US South region allows any incoming/outgoing port.

    On the other hand, firewall is also enabled by default in the Ubuntu server and only port 22 is open.

    A more elegant solution would be to open only ports that you want to expose, for example port 8888:

    $ sudo ufw allow 8888/tcp

    You can then check ports opened with the command:

    $ sudo ufw status

    Important: the answer here is valid only for VMs created in the Bluemix US South region. For VMs created in the Bluemix United Kingdom region check the product documentation to better understand security groups.
