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 port from 8890 to 80?

I have ran the following command ipython profile create to create a profile.

Then edited ipython_notebook_config.py and edited it to contain the following:

c = get_config() c.NotebookApp.port = 80 

When I try to run python notebook. I get the following error:

ERROR: the notebook server could not be started because no available port could be found.

---

Hoever, nothing else seems to be using port 80. Apache does not boot at startup and is disabled. I have even used netstat to see what is using each port.

Answer 1

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

To change port temporarily, indicate a different port number when we start jupyter notebook server from a terminal by firing following command.

jupyter notebook --port 9999
