Unable to use -o allow_other with sshfs (option enabled in fuse.conf)

Question

I have the following on my /etc/fuse.conf file:

# Set the maximum number of FUSE mounts allowed to non-root users.                       
# The default is 1000.                                                                   
#                                                                                        
#mount_max = 1000                                                                        

# Allow non-root users to specify the 'allow_other' or 'allow_root'                      
# mount options.                                                                         
#                                                                                        
user_allow_other    

But when I try to mount a remote path with the option allow_other:

> sshfs name@server:/remote/path /local/path -o allow_other

I get:

fusermount: failed to open /etc/fuse.conf: Permission denied
fusermount: option allow_other only allowed if 'user_allow_other' is set in /etc/fuse.conf

I have triple checked and the option user_allow_other is uncommented in my fuse.conf,as I copied above.

I have also executed sudo adduser my_user_name fuse (not sure if this is needed though), but I still get the same problem.

Why is it not parsing the /etc/fuse.conf file correctly?

Solution 1

A better solution might be to add the user to the fuse group, i.e.:

addgroup <username> fuse

Solution 2

Given the message failed to open /etc/fuse.conf: Permission denied, I suggest

chmod a+r /etc/fuse.conf

Then log out and log back in!

And add existing user to fuse as secondary group: usermod -a -G existing_user fuse # in case addgroup is not present on your system

This is the correct answer

@MountainX it would be nice to know why exactly

on ubuntu 20.04 i tried that but got addgroup: The group fuse' does not exist.`

It will be nice to have the script to revert it, for people that doesn't understand chmod at all ...

Group fuse was eliminated after Debian 8.
