1. Redhat 7.3 NIS errors (Internal NIS error)
Hello.
I am running NIS on a newly installed RedHat 7.3 box. Originally, I
had the box running as a YP slave. The YP master is a Sun box running
Solaris 2.7. About two weeks after I installed 7.3, I occasionally get
these errors in the logs:
Jul 16 23:09:55 butthead amd[26613]: nis_isup: error getting the order
of map amd.raid_home: Internal NIS error
Jul 16 23:09:55 butthead amd[26613]: nis_isup: error getting the order
of map amd.net: Internal NIS error
Jul 16 23:09:55 butthead amd[26613]: nis_isup: error getting the order
of map amd.lab: Internal NIS error
When this happens, users get kicked off and can't login because the
machine is not getting the passwd map from the master. I don't believe
this has anything to do with amd, just that amd is the only thing
complaining. The one time I caught it having this problem, I noticed
that when I did `ypcat passwd`, the passwd file
was coming from another NIS master in the subnet that serves a
different NIS domain. I shutoff ypserv and let it bind to the
ypmaster. Initially, that worked, but the problem surfaced again.
The problem usually clears itself after a short period of time.
I am guessing there is some problem with ypbind. This machine is the
only one in the affected NIS domain that is running Redhat 7.3. None
of the other machines are having any problem. However, I just recently
setup the other NIS master (also Redhat 7.3) serving another NIS
domain, so maybe this is causing some problems.The affected machine
used to run Redhat 6.2, and there were no problems with that setup.
Anyone have any ideas on how to troubleshoot this?
Thanks.
Peter.
