When trying to run a basic sshfs mount,
Code:
sshfs user@server:/home/user /mount/point
...you get this:
Code:
fusermount: mount failed: Operation not permitted
...even when you own the mount point, and permissions are wide open. Simple fix...run:
Code:
sudo chown root /usr/bin/fusermount
sudo chmod u+s /usr/bin/fusermount
And it should work then.
