netatalk with external usb hard disk

[samick88]

I want to use my WD Mybook as backup device for leopard.
I read the article
http://www.kremalicious.com/2008/06/...achine-volume/

Everything works fine if I use my local hard drive.
Once I configure netatalk to use my usb-harddrive, I get a connection failed

my /etc/fstab entry:

/dev/sdb4       /media/mybook/backup    ext3 defaults,user,noauto 0     0

my /etc/netatalk/AppleVolumes.default

/media/mybook/backup TimeMachine allow:myuser cnidscheme:cdb options:usedots,upriv

directory settings /media/mybook/backup

drwxrwxrwx   5 myuser myuser  4096 2009-01-16 20:23 backup

I'm using ubuntu server 8.10

Do you have any idea?
Kind regards

I'v found the solution. I've uninstalled netatalk from ubuntu 8.10 and followed the tutorial from:
http://www.zaphu.com/2008/04/29/ubun...-protocol-afp/

did some modifications from
http://www.kremalicious.com/2008/06/...achine-volume/


server and time machine is working now.
