Have you tried the smbtree program in samba-3.0.0?

It seems to be a bit broken in samba-3.0.1pre1 though ... firstly it
wants to be able to write to the log directory, and after changing the
perms on the log directory, it dies loading codepages:

write(1, "Adding chars 0x7d 0x0 (l->u = Fa"..., 52Adding chars 0x7d
0x0
(l->u = False) (u->l = False)
) = 52

0x0
(l->u = False) (u->l = False)
) = 52

Buchan,

I just tried this with CVS checkout from 8 hours ago and it works fine on
SuSE 8.2.

I'm not sure what the problem might be at your end as I can not reproduce
the failure. Anyone else having problems with smbtree?
