iirc that's not supported in OpenBSD's FUSE implementation yet.

Re: Can't use sshfs as user

[Daniel Boyd]

Any idea how to get it to map the uid?  Once I mount the folder, I can't
access it.

I've tried -o idmap=user, -o uid=1000, etc. None of that seems to work.

You only need 660 and your user in 'wheel' group.

Oh, that was it.
It works after a
# chmod 666 /dev/fuse0

Not sure it's really secure thought.

- read/write permissions on /dev/fuse0
- mount point owned by the user

I tried to add -o uid=1000 -o gid=1000 to sshfs, but he does'n seems to
understand these options despite the man page says.

Where am I wrong?

Can't use sshfs as user

[Thuban]

Hi,
I try to mount a directory with sshfs as non-root, but I get the
following error :

fuse_mount: Permission denied

I don't get it. I have "kern.usermount=1" in /etc/sysctl.conf, but
according to [1] I need to use some option about uid. But which ones?

Regards.
