This is a ported/modified version of the yppush program from the yps-0.21 package from the NYS project. This program is used to propagate updated NIS maps from an NIS master to an NIS slave. It's normally invoked by /var/yp/Makefile. This version of yppush has been modified in the following ways: - Cleared up several Linux/BSD incompatibilities, largely involving header files. - converted from GDBM to DB with extreme predjudice. (well, not really...) - removed lots of ugly debugging code that really didn't do anyone any good. - Fixed a couple of inaccurate/badly formatted error messages. - Renamed some functions to avoid collisions with certain YP routines hidden inside libc. - Small signal handling kludge: Linux has different struct sigaction that us. - Incorporated some functions from the yps-0.21 library that yppush was dependent on. Like ypxfr, this works, but could use come cleaning up.
