NIS maps sync after password change

[YairZaretski]

Hey,

I have a NIS Master and two NIS Slaves in my system. I also configure password expiration every 3 weeks.
My problem is, if a user tries to login to one of the slaves and is prompted for a new password, it is being changed in the NIS Master. Therefore, until ypxfr is run from the slave, the passwords in the Master and in the Slaves are not the same and the user cannot login using any one of them.

my question is, can anyone think of a better solution than running the ypxfr cron job every minute?

Please help me with this..
Thanks,
Yair

You simply haven't configured the yppasswdd (yppasswd daemon) correctly. Having to do a ypxfr every minute is Looney Tunes; once per hour should more than suffice. Look in /etc/rc.config.d/namesvrs and make sure that the YPPASSWDD_OPTIONS (especially -m options) are properly set. Man yppasswdd for details.

Hi,

please keep in mind, that yppasswdd is needed only on the NIS master itself!

Hey,

ypxfr only pulls the new copies of the maps from the master to slave, if there are any changes (ONLY if there are changes on the maps).

You can also do a yppush on the master server so that it will propagate the maps to the slave servers.


How about a script (a watchdog) on the master server which will check for the passwd changes and if there are changes, then it will just call a yppush to push it to the slave servers - not a very good solution!

The last NIS admin stuff I did was five years ago or more.
