Hi all.
I installed unfs3 according to this toppic: http://forum.openwrt.org/viewtopic.php?id=11847

my /etc/exports looks like this:

/mnt/usb/ftp    (rw,no_root_squash,insecure)

i can see the shares available:

showmount -e 192.168.1.161
Export list for 192.168.1.161:
/mnt <anon clnt>

I try to mount the share

sudo mount -t nfs 192.168.1.161:/mnt/usb/ftp /mnt/nfs
mount.nfs: access denied by server while mounting 192.168.1.161:/mnt/usb/ftp

checking the log of my router shows this:

Jun 20 17:38:13 midge daemon.info unfsd[1788]: 192.168.1.17 attempted to mount non-directory

i insmod:
- sunrpc
- lockd
- nfs

i started
- portmap
- unfsd

I checked everything multiple times.... but i can't find the problem.
Does somebody knows the answer?
