Hey I want to setup a reverse sshfs tunnel. I have a home server which sits behind some type of NAT which makes it impossible for a remote computer to sshfs the home file system. On the local computer I run the following command to establish a reverse ssh tunnel:

ssh -R 14443:localhost:22 remoteUser@remoteComp

From the remote computer I can successfully ssh to the home server:

ssh localUser@localhost -p 14443

However I can not mount home file system:

sshfs -p 14443 localUser@localhost:/home/localUser RemoteFolder/

as I receive the following error:

fuse: failed to open /dev/fuse: Permission denied

Ofcourse the remoteUser has been added to the group fuse. Any help appreciated :)

Could check on your remote system what the permission of /dev/fuse is? ls -l /dev/fuse. It means that your user/group is not able to write to /dev/fuse on your remote system.

Heres the result crw-rw---- 1 root fuse 10, 229 May 8 17:32 /dev/fuse Do I need to change something? Thanks :). –  Kurent Aug 24 '12 at 15:56
    
So it is owned by group fuse. What does 'groups remoteUser' return? If you do not see fuse, then either you did not add it to the fuse group or need to log out and log in again. –  johnshen64 Aug 24 '12 at 16:34
    
In this case remoteUser = root. groups root returns root : root fuse. This is after logout & login, and sshfs is still returning the same error. –  Kurent Aug 25 '12 at 7:01
    
Thanks for help. –  Kurent Aug 25 '12 at 9:01

The problem was with the remote server I'm using. Fuse was not functioning on the Virtual Private Server(VPS), and the issue was resolved by the VPS admin. The admin had to 'enable fuse'.

This maybe an issue for VPS hosted with openvz.
