Yes, actually I've determined that whether I use smbmount or
smbclient, I can recurse until I get 40 directories deep in the share.
This is the case no matter how I do the recursion, so I assume 40 is
hardcoded someplace as the max limit.
I noticed on page 1 of the wget manpage, 2nd P under Description:
"Infinite recursion loops are always avoided by hashing the retrieved
data." Is this for some reason not applicable to smbclient, or would
it be useful to add this, or should I be posting this to the samba

Do you mean in smbclient? So currently thats not possible, you're
suggesting it is useful to add such a feature/option?

I actually am using MySQL at the moment. Indexing 100,000+ files with
a text file (and doing searches!), well, yes that would be bad.
Thanks again for your help
