cannot quit jupyter notebook server running

So I found a solution.

Since jupyter notebook list tells you which ports the notebook servers are running on I looked for the PIDs using netstat -tulpn I got the information from http://www.cyberciti.biz/faq/what-process-has-open-linux-port/

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       
PID/Program name    
tcp        0      0 0.0.0.0:8649            0.0.0.0:*               LISTEN      
-                   
tcp        0      0 0.0.0.0:139             0.0.0.0:*               LISTEN      
-                   
tcp        0      0 0.0.0.0:33483           0.0.0.0:*               LISTEN      
-                   
tcp        0      0 0.0.0.0:5901            0.0.0.0:*               LISTEN      
39125/Xvnc

Without looking too hard I was able to find the ports I knew to look for from jupyter notebook list and the processes running them (you could use grep if it were too hard to find them). Then I killed them with kill 8337 (or whatever number was associated).


Windows Systems commands on Command Prompt

Be careful to save all the changes made in your notebooks prior to kill the jupyter notebook server process.

i) find the port number used by jupyter notebook server

jupyter notebook list

ex.)

jupyter notebook list
Currently running servers:
http://127.0.0.1:8888/ :: D:\kimkk\Documents\JupyterNotebook

ii) find process ids that use the found port number of jupyter notebook

netstat -ano | find "found portnumber"

ex.)

netstat -ano | find "8888"

  TCP    127.0.0.1:8888         0.0.0.0:0              LISTENING       24140
  TCP    127.0.0.1:8888         127.0.0.1:55588        ESTABLISHED     24140
  TCP    127.0.0.1:8888         127.0.0.1:55612        ESTABLISHED     24140
  TCP    127.0.0.1:55588        127.0.0.1:8888         ESTABLISHED     6492
  TCP    127.0.0.1:55612        127.0.0.1:8888         ESTABLISHED     6492
  • find rows with second column value equals to "8888". In above example first, second, and third rows are target rows. In those rows, you can find PID in the last column (ex. 24140).

iii) kill jupyter notebook process with found PID

taskkill /PID found_PID /F

ex.)

taskkill /PID 24140 /F
  • /F means forcely kill the process.

FYI, Jupyter notebook from version 5.1 supports stop command as follows:

jupyter notebook stop 8888
