The www.linux-sna.org dropped of the net years ago and all files seemed to be lost.
But thanks to John Decker I am able to put them on-line again!
The state of these files is unknown: I cannot tell you of they can talk to a real SNA device or even compile at all.
Anyway, here they are; good luck!
This project has stopped now that Jay Schulist decided to open-source & gpl his SNA for Linux implementation.
You can find it at: http://www.linux-sna.org/
SNA is a network-protocol designed by IBM. It is a hierarchical design, very static and mainly in use
for communcation with mainframes.

http://www.linux-sna.org/ They have a commercial SNA implementation, complete with the same functionality as microsoft SNA-server for Linux. If you're looking for SNA under Linux which is supported take a look here.
