I ran across this error while trying to mount a remote file system to my local host using SSHFS.
The command I was using was in the form of:
sshfs root@remote:/path/to/dir ./localDir
- I am logged into the local system as root
- I have a valid SSH key to the remote... I can
ssh root@remoteand get a prompt
- I tried setting permissions to both the source and destination 777 just for testing - same error
- I found lots of similar error messages via search engines, but none of the "bad mount point" results also included "Permission denied." I think this is a distinct issue.
