OK, I don't know if it's just me, but I'm having terrible problems with
using Linux as an NIS server.
Until a few weeks ago, I had a Sparc 1+ running SunOS 4.1.4 as the NIS
server (about 6 SunOS clients and 6 Linux clients). It worked flawlesly
other than being slow. Then I made the mistake of migrating the thing over
to a Linux machine (kernel 2.0.32). I've had endless problems ever since.
Sometimes ypserv will basically stop working. All clients get "connection
refused." Often, I'll see something like this:
[root@present /root]# ps auxw | grep yp
root 192 0.0 12.1 8052 7656 ? S Nov 8 5:51 ypserv -b
root 204 0.0 0.7 940 456 ? S Nov 8 0:00 rpc.ypxfrd
root 215 0.0 1.0 1024 660 ? S Nov 8 0:00 rpc.yppasswdd -D

root 26678 0.0 12.1 8052 7656 ? S 14:19 0:00 ypserv -b
root 26683 0.0 12.1 8052 7656 ? S 14:19 0:00 ypserv -b
root 26684 0.0 12.1 8052 7656 ? S 14:19 0:00 ypserv -b
Other times, ps will look normal, but it will just not be working.
Sometimes it will come back by itself, sometimes it needs a restart or
even a reboot to get things to the right state. Sometimes things will be
working but just be very, very slow. The problem will go away as randomly
as it came.
I updated to the newest yo* rpms I could find:
yp-clients-2.2-7
ypserv-1.3.6-1
ypbind-3.3-9
yp-tools-2.0-1
It is still unusable.
I'm about ready to install FreeBSD or something else, but I'm hoping that
someone can save me the trouble by giving me some tips on making this work
better (or at least a better way to track exactly what is happening since
it almost never logs anything useful).
TIA.
