ypcat, yppoll, ypmatch). The most important program is ypbind. This

|
program must be running at all times, which means, it should always appear
|
|
in the list of processes. It is a daemon process and needs to
|
|
be started from the system's startup file (eg. /etc/init.d/nis,
|
|
/sbin/init.d/ypclient, /etc/rc.d/init.d/ypbind, /etc/rc.local).
|
|
As soon as ypbind is running your system has become a NIS client.</P

need a NIS server program (usually called ypserv). <A

shared library "/lib/libc.so.x" contain all necessary system calls to

succesfully compile the NIS client and server software. For the

GNU C Library 2 (glibc 2.x), you also need /lib/libnsl.so.1.</P

>Some people reported that NIS only works with "/usr/lib/libc.a" version

4.5.21 and better so if you want to play it safe don't use older

libc's. The NIS client software can be obtained from:</P

>Once you obtained the software, please follow the instructions which
|
|
come with the software. yp-clients 2.2 are for use with libc4 and libc5
|
|
until 5.4.20. libc 5.4.21 and glibc 2.x needs yp-tools 1.4.1 or later.
|
|
The new yp-tools 2.4 should work with every Linux libc. Since there was
|
|
a bug in the NIS code, you shouldn't use libc 5.4.21-5.4.35. Use libc
|
|
5.4.36 or later instead, or the most YP programs will not work.
|
|
ypbind 3.3 will work with all libraries, too. If you use gcc 2.8.x or
|
|
greater, egcs or glibc 2.x, you should add the ypbind-3.3-glibc5.diff
|
|
patch to ypbind 3.3. If possible you should avoid the use of ypbind 3.3
|
|
for security reasons.
|
|
ypbind-mt is a new, multithreaded daemon. It needs a Linux 2.2 kernel
|
|
and glibc 2.1 or later.</P
