Not from Linux, but I have HD access when I boot into Win 2k.

Yes. The question is why the firewall prevents SuSE Linux 7.3 Pro from
finding the other computers in the workgroup, but not in Win 2k? The firewall
is the Win version of Norton Personal Firewall and I am conversant only in
the Mac version of same. The GUI is very different.

When I disable the firewall, I can ping to Win 98 boxes. Not only that, but I
was successful in getting LinNeighborhood to display the computers after a
"modprobe smbfs". However, when I tried to mount one at /home/usr/mnt/<host>,
I received the following error, despite having installed all of the smbclient
package:

"smbmnt must be installed suid root for direct user mounts (500,500) smbmnt
failed: 1"

True, but I was hoping to avoid spreading viruses, Trojan Horses, worms, etc.
from one computer to the other with the firewall. We have already had a case
of a Trojan Horse on one of the Win 98 boxes and as it is hard to monitor
what wives and kids download, I thought that this would be added protection
;-)
