Problem with NIS maps

Problem with NIS maps

[Clif Smith]

I'm in a large heterogeneous environment located across multiple 
locations.  I use NIS maps such as:
/home -rw austin:/export/home boston:/export/home phoenix:/export/home

with the following in /etc/auto.master:
/nis      yp      auto_indirect_nis

With AIX and Solaris, automounter chooses the server with the fewest
hops to determine which server to mount from.  Unfortunately, it appears
Suse's 8.1 implementation of automounter (v3.1.7-556) seems to choose 
the first listed.

Has anyone run into this before?

Thanks, Clif

Sorry, SuSE have chosen not to update to autofs v4.

The most recent version handles this.

You may wish to try building the SRPM from one of the FC distributions.

Yes, it is called replicated server.

It is supported in the autofs-4.1.x family.  You should upgrade.

Hello,

We don't use the replicated stuff so I am not sure if it works with SuSE.
But 8.1 has autofs v4 (not the latest one though), you might wanna check
it out.

SuSE 9.1 includes 4.0.0, my release of the largely unchanged 4.0.0pre10. 
I don't know what patches they've applied but still quite old.

I ASSuMEd compiling it from source (4.1.3) would be even "cleaner", but 
when I see that /etc/init.d/autofs has:
if [ -f /etc/debian_version ]; then
    system=debian
elif [ -f /etc/redhat-release ]; then
    system=redhat
else
    echo "$0: Unknown system, please port and contact 
autofs@linux.kernel.org" 1>&2
    exit 1
fi

Why is the source so restrictive?

Moving on to the FC SRPM.

Yes, that's a good point.

This is one of the issues that should be addressed when the master map 
parsing is taken into the daemon. It's pretty much the highest priority 
task atm.
