problems with smbmount in /etc/fstab

[Luca Ferrari]

Hi all,
I'm using ubuntu 7.1 but I've got a few problems with the following entry in 
the /etc/fstab file:

//g2nas9/camera_oscura                   /backup/mammuth  smbfs 
username=backup,password=backup,ip=192.168.1.209 0 0

That should mount at the boot the samba share, but it does not. In particular 
if I manually execute:
mount /backup/mammuth
I can mount the share, but any idea on why it is not mounted at the boot?


Thanks,
Luca
