I've set up a Linux and Mac zeroconf (netatalk) LAN. On the Linux box
(Debian Etch) I have a shared directory for passing files to/from the

allows a peer-to-peer network model, netatalk only provides for a Mac to
"see" a Linux system but the Linux system can't "see" a Mac for file
sharing).
As root on the Linux box I created a new user "lanshare" accepting
standard permissions for the /home/lanshare directory
owner: rwx group: r-x others: r-x
I also added to the "lanshare" group the other Linux users that I want
to be able to use a shared directory.
Then I logged in as "lanshare" and created the folder "public" in
/home/lanshare/. For this "public" folder I modified the permissions to
owner: rwx group: rwx others: ---
and I set the sticky bit.
The idea is to allow various users on the Linux box the ability to
create and delete their own files in /home/lanshare/public and to
read/copy any files therein. The Mac will create and delete files
therein as the user "lanshare."
This seems to work as intended, but I'm wondering if such is the best
way to handle the setup?
Thank you,

IIRC, things may become messy, when users start to *copy* files to
/home/lanshare/public. Then the sticky bit is not preserved; it works
only for files *created* in that directory. It should be noted somewhere
in the info pages.
The solution in our case was to export the mount with restrictions, ie.
/etc/exports on the computer with the 'public' fs has a line:
/home/lanshare/public
192.168.0.0/255.255.255.0(anonuid=503,anongid=100,all_squash,rw,sync)
just replace your network and the uid of user lanshare.
Hope that helps.
