Ignore my previous e-mail.  The client works fine.  It was a long day at 
work and I put a bad IP address in my yp.conf file...

So, now I have a yp.conf file with two servers: my test box and a 
production NIS server.  I wrote a script that'll keep restarting ypbind 
until it picks my test server.  Then I run ypwhich, ypmatch, and ypcat 
to verify it works.

I kill the ypserv daemon on the test server.  I run ypwhich and it 
immediately rebinds to the production server.

I repeat the process, except when I kill ypserv, I try ypmatch on the 
client.  This spits out an error message, but then rebinds to the 
production server and finds the record I'm trying to match.

I repeat the process again, except after killing ypserv, I try ypcat. 
This fails and does not cause the client to rebind.

This is all using glibc-2.3.2 and ypbind-1.12 as shipped with RedHat 
Enterprise Linux 3 with Update 1 plus the NIS patches.

I haven't looked at why ypcat fails to trigger a rebind yet.  Hopefully 
I can find some time tomorrow afternoon to do that.

Thanks!
