sftp mounting issues #69

Closed aurany closed 2 years ago

aurany commented 2 years ago

Hi,

I'm running the sftp-image as a separate container on the same server as JupyterHub which is also a container. I have started the sftp container but having some trouble to login. After doing some research i created a debug logfile to see that the user validation actually is ok. The problem seems to be the mounting that happens inside the jupyterhub-token-verify.py

What should theese variables be?

SRC_DIR = PosixPath("/mnt/home")
DEST_DIR = PosixPath("/export/home")

From the logfile (server and username are replaced by SERVER and USERID)

root@SERVER:/# cat /tmp/debug.log

The problem was that i had the wrong SRC_PATH.
