Q3 2018 - APAR # UI59973 Jupyter

There are two new settings available for Jupyter to configure a port range:

c.ConnectionFileMixin.starting_port and c.ConnectionFileMixin.max_kernels.

Each kernel requires 5 consecutive ports so if you want to use 5 kernels you would need 25 consecutive ports. These two options are set in your Jupyter Notebook and Jupyter Kernel Gateway configuration files. The configuration files are located by default in ~/.jupyter. If you do not have configuration files, they can be generated with the following commands:

jupyter notebook --generate-config and jupyter kernelgateway --generate-config
