Thanks to Robert and also to Sundar for their replies. What was driving me
crazy was that the samba logs showed nothing. I added the ipchains entries
Robert suggested and it worked! (Well, actually, I had to fix some other
problems, but this time there were actually entries in the samba log files--
and I DID get it working.) I guess I didn't realize that the medium security
level was so strict -- oh well, it was a learning experience.
Thanks agian,
Vaughn
