correctly (specified wrong fields to awk). Note that the files in question
are noe the local /etc/master.passwd and /etc/passwd files: this Makefile
expects there to be a seperate master.passwd file under /var/yp for NIS
database creation.
executes after it finishes updating the raw master.passwd file. The script
is just there to invoke /var/yp/Makefile to build new maps and yppush them.
We could have yppasswdd run /var/yp/Makefile directly, but this allws a bit
more flexibility: the user may decide to run some other commands too.
This is a ported/modified version of yppasswd from the NYS yppasswd-0.5
package. This package has code in it from both Olaf Kirch and Theo
de Raadt. There are GPL references and BSD-style copyright all over the
place... hopefully I won't get flamed into oblivion for commiting this.
This program has been modified from the original in the following ways:
- Changed the ALLOW_CHFN and ALLOW_CHSH compile-time options into
run-time options.
- Demolished the password update functions and replaced them with
routines to handle FreeBSD-style passwordd databases. It is expected
that a seperate master.passwd file will be maintained for use with
the NIS maps. yppasswd will have to be told where it is:
% yppasswdd -m /var/yp/master.passwd
A /var/yp/passwd file will be generated from /var/yp/master.passwd by
/var/yp/Makefile. When yppasswdd has finished modifying the master.passwd
file, it will invoke /usr/libexec/yppwupdate, which is a script that
will run /var/yp/Makefile to generate new maps and push them.
Note that there are copies if pw_util.c and pw_copy.c here. This is
deliberate: they are *not* identical to the originals. Very similar, yes,
but not identical. *sigh*
This is a hacked-up port of the ypserv-0.11 server from the NYS project
written by Peter Eriksson.
The original package included some map creating and dumping tools and
was based on GDBM. This version has been modified in the following
ways:
- GDBM replaced with DB and many weird hacks made to the read_database()
function because of this.
- implimented the ypxfr service (using ypxfr from the yps-0.21 package,
aso from the NYS project)
- added code to check the TCP port from which NIS requests originate:
the server will refuse to serve the master.passwd.{byname|byuid} maps
if the request doesn't come from a privileged port. Normally, only the
superuser can issue such a request. Requests for the passwd.{bynam|byuid}
maps aren't affected. There will be a small change made to getpwent.c
in libc to complement this.
- added code to do DNS lookups via actual resolver queries instead of
relying on gethostbyname() and friends. The author noted in the original
documentation that a loop condition could arise where the server would
query itself for hostsname lookups. Using direct DNS lookups prevents
this from happening.
- added code to properly fork() the server into the background unless
invoked with the -debug flag.
- Added combined syslog/perror function.
- fixed a few bugs (which were probably introduced by all the other
changes)
- Created a bmake Makefile.
Note that this package can be linked against the tcp_wrapper package
to provide address-based authentication, but this isn't done by default
since the tcp_wrapper package isn't part of FreeBSD.
This program is used for both generating and dumping NIS maps. It's very
similar to the 'makedbm' command in SunOS. This program was ported from
the yps-0.21 package. It's close to the original except for the GDBM to
DB conversions. This was simple compared to the other YP components.
