Changing the default port for iPython notebook server / Jupyter
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.
$ sudo netstat -lnp

Answer
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
