[sshfs] Weird problem using sshfs

[Dirkjan O. <di...@oc...>]

I just installed FUSE 2.7 and FUSE 1.9 on my 2.6.23 kernel from
Gentoo, but it doesn't work.

djc@darwin var $ sudo sshfs -odebug,sshfs_debug aera@10.247.96.33: transtrend
Server version: 3
unique: 1, opcode: INIT (26), nodeid: 0, insize: 56
INIT: 7.8
flags=0x00000003
max_readahead=0x00020000
   INIT: 7.8
   flags=0x00000001
   max_readahead=0x00020000
   max_write=0x00020000
   unique: 1, error: 0 (Success), outsize: 40

(After this, I get nothing. As a normal user, I get "fuse: failed to
open /dev/fuse: Permission denied").

This kind of seems to work (without debug, there's no output at all),
but it doesn't:

djc@darwin var $ ls -l
ls: cannot access transtrend: Permission denied
total 1
...
??????????  ? ?      ?      ?            ? transtrend
...

Am I doing something stupid? I looked to the FAQ, but couldn't find an
answer. One problem might be that this SSH connection should go over
an OpenVPN tunnel, which is on the tap0 interface and requires a
different route. Would that work at all, or this is a bit too
far-fetched?

Cheers,
