* cleanup for -Wall
* use __RCSID
the following were inspired by openbsd:
* only allow connections from reserved ports
* implement -insecure, which turns off the above restriction (required
for sunos 3.x and ultrix)
* prevent more than 100 domains from being bound at once, preventing
a denial of service attacks
This is a compromise between the Solaris 2.5 naming of this file
(/var/yp/binding/domain/ypservers and /var/yp/binding/domain/vers)
and traditional NetBSD naming (/var/yp/binding/domain.vers).
Changing to the Solaris naming makes the C library incompatible
with ypbind. While it's easy to change the C library, I don't feel
right about introducing a gratuitous incompatibility.
The current name (/var/yp/domain/ypservers) conflicts with the name
of the YP map listing slave servers for a domain.
Per discussion w/ Chris Demetriou and Luke Mewburn.
of YP servers a client should bind to, mostly verbatim, but slightly
modified for better semantics when nagging servers if a ypset has been
issued. Default to broadcast mode if no .ypservers file is present.
Documentation changes to match, slightly tweaked by Scott Reynolds and
myself.
Closes PR #1759.
