How to remove a slave server from ypcat -k ypservers list ?

[Sammy_2]

This is NIS. Do I need to recreate NIS dbase with "ypinit -m" on the master server and not include the server name ???
The server in question no longer exist.
Thanks

No need to recreate the NIS database .. on the master server do this ..
# cd /var/yp/
# makedbm -u ypservers >> ../nis-server-list
# vi ../nis-server-list
==> Delete the hostname of the unwanted server.
# makedbm ../nis-server-list ypservers
# /var/yp/ypmake
==> That should push/update the new ypservers map out to the rest of the slaves. Check on the slaves side just to make sure /var/yp//ypservers.dir and /var/yp//ypservers.pag are updated.

FYI you can also (instead of running ypmake) run ..
# yppush -v ypservers

Hello!

As mr. Chan wrote or you can made ypinit for
the server and give the new list.

Thanks Chan,
Works like a charm. But how come when I do a "ypcat -k ypservers" on master server, I do not see the deleted server (as it should). But on slave server, the same command show the old server name.Anyway, your answers was worth 10 points.

Hi Sam,
Did you verify (on the slave side) that /var/yp//ypservers.dir and ypservers.pag file got updated ? The timestamp will tell you. If they do not get updated, there has got to be some problem with the ypmake. Try this .. on the master side , run
$ yppush -v ypservers
anyway to copy the ypservers db map and see if that works for you.

Chan,
I had to yppush to make it work. And dates on the slaves are current now
Thanks a bunch.

I did some check for you .. it seems ypmake does not push out ypservers map (just look at the ypmake script in /var/yp). That confirms that yppush needs to be run manually for the update to happen.
