Thank you for the example code!  I verified that client and 
server communicated, and that a standard file-based unix socket 
was not created.  Then I simply changed the socketName to the 
socket I was interested in, and tried the client against it.  
Still no luck unfortunately, same error as earlier.

I have noticed that successful connect calls appear to show the 
size as 23, whereas unsuccessful connect calls show 24.

This works (socat):
     connect(3, {sa_family=AF_FILE, path=@"/var/run/ptmd.socket"}, 
23) = 0

This does not (from deneme, modified):
     connect(3, {sa_family=AF_FILE, path=@"/var/run/ptmd.socket"}, 
24) = -1 ECONNREFUSED (Connection refused)
