A port for the HP machines has already been done. CSRG works almost exclusively on HP-86k machines these days. For the Sun-3 a separate port would have to be done, although one could use large parts of the HP and upcoming SPARC port. >I would like to be able to read some of the man pages, but when >I try to run them through nroff, I get garbage.

I haven't looked at the nfsd sources. But, depending on how much work is done in the user process and how much in the kernel process this may be easier to accomplish or not. >We would really like to be able to use the BSD code for secure >rpc but this would seem to require a composite kernel containing >a mixture of BSD code for rpc and SUN-OS code for everything else. >Is such a beast possible?

Basically one has to port the BSD sources to the Sun kernel. -- Christoph Badura --- bad@flatlin.ka.sub.org AIX is a better... is a better... is a better... OpenSystem. IBM Rep at GUUG Symposium '92
