Something wrong with Alpha's and IPX in such that when you set a machine up with mars-nwe on an Alpha, other clients on the network cannot see the server. You can see yourself on the alpha box by using 'slist' but also cannot see other netware (emulated or not) servers on the network. Doesn't seem like any IPX packets are being place on the wire or being received. Also this is difficult to do further checking due to the lack of IPX utilities such as ipx-utils for the Alpha architecture.
fixed in rawhide with the removal of mars.
