Changing the default port for iPython notebook server / Jupyter

Question

I am trying to run an ipython notebook / jupyter server on a machine behind a firewall. The only port which is open is port 80. So was wondering how I can change the default por

Answer 1

ipython notebook --ip=0.0.0.0 --port=80 or
jupyter notebook --ip=0.0.0.0 --port=80

is what i did to run ipython in my vagrant box. (Opened up the ports on the vagrant box to access it on my host mac)

usage: ipython [-h] [--certfile NOTEBOOKAPP.CERTFILE] [--ip NOTEBOOKAPP.IP]
               [--pylab [NOTEBOOKAPP.PYLAB]]
               [--log-level NOTEBOOKAPP.LOG_LEVEL]
               [--port-retries NOTEBOOKAPP.PORT_RETRIES]
               [--notebook-dir NOTEBOOKAPP.NOTEBOOK_DIR]
               [--config NOTEBOOKAPP.CONFIG_FILE]
               [--keyfile NOTEBOOKAPP.KEYFILE] [--port NOTEBOOKAPP.PORT]
               [--transport KERNELMANAGER.TRANSPORT]
               [--browser NOTEBOOKAPP.BROWSER] [--script] [-y] [--no-browser]
               [--debug] [--no-mathjax] [--no-script] [--generate-config]

Incase the port is already occupied, see what's blocking it - inmy case it was an old instance of ipython which had not been terminated properly. I kiiled them all with this command

ps auxww | grep 'ipython' | awk '{print $2}' | xargs sudo kill -9
