There is a new build of Samba 3.2.0 for MorphOS. Its developer reports that it works well overall. A known limitation is that it is impossible to browse the shares from computers running Windows (OSX and Linux showed no problems). However, mounting shares directly works fine in any case.
As the developer has access to MorphOS 2.x running on an Efika only, he is looking for help from Pegasos owners who would like to test the software on their hardware. You can contact Michael (micken) by sending him a PM here on MorphZone.
