rdist for SCO Unix

The latest rdist (6.1.3 as of this writing) did not support SCO Unix 3.2v4.2 out of the box. Therefore I had to undertake a porting effort.

This is what you will need to build rdist on SCO Unix.

• GNU regex version 0.12 -- this may have been superseded by rx, but an old library seemed appropriate for an old operating system.
  • Run make check.
  • Be sure to archive the regex.o, alloca.o and xmalloc.o object files into libregex.a with a command like
    ar rv libregex.a regex.o test/alloca.o test/xmalloc.o
  • Install libregex.a into /usr/local/lib or some other location.
• You will need an implementation of socketpair(), which SCO Unix does not provide. Here is the socketpair source code I wrote. I hope it's correct; it seems to be close enough for SCO.
• SCO Unix does not use any sort of high-level file system mount entry interface, so you will need to write some functions for the src/filesys-os.c module. This patch contains the modifications I made to rdist 6.1.3 to implement this functionality for SCO Unix. It has not been rigorously tested, but it has been used successfully for some basic file transfers. (To apply this patch you will probably need GNU patch. I had to use GNU diffutils to produce it. Ah, the joys of SCO.)
• You will need an OS configuration file for rdist. This is built by customizing config/os-TEMPLATE.h for SCO Unix. Here is the configuration file I used. You will have to name it os-hostname3.2.h where hostname is of course your system's hostname. The shame of SCO Unix is so great that it will not confess its identity when asked, even under great pressure (uname -a, uname -X, etc.).

I probably screwed something up, but at least I've been able to send files from a HP-UX 10.20 system to a SCO Unix 3.2v4.2 system. Your mileage may vary, etc.
