Description of problem:
In a patch submitted by a customer and applied as is, USE_BROADCAST was set to 0. It's normally set to 1 (from upstream) which makes ypbind do an RPC "ping" to all NIS servers at once and pick the first one that responds as the fastest. If USE_BROADCAST is set to 0, ypbind will try each of the servers in /etc/yp.conf in order, waiting for a timeout between them.
Upstream has said this code hasn't been used or really tested in a long time. Additionally, it waits 60 seconds before trying the next server in the /etc/yp.conf file, which could lead to long time before a server is found to bind to if the first servers in the yp.conf file aren't responding.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Run tcpdump or ethereal when starting the ypbind service

I was unable to find a case where ypbind acted differently when USE_BROADCAST
was changed from 0 to 1.
I've removed the USE_BROADCAST section from the patch, but am unable to test
what it fixed. It has been built into ypbind-1.12-5.21.6. An errata is also
Is an errata coming for this soon?
This sort of change is really unnacceptable for anyone who has been using ypbind
w/ Red Hat Linux for any length of time... especially after sweating a bunch of
changes that were needed in the code that then got thrown out by this
I believe that the fix will be in RHEL3U5. (The fix being USE_BROADCAST is
reverted to its old setting, 1).
I don't see it in U5, which seems to be out now.
What is the version of the rpm you have? rpm -q ypbind.
Check out ypbind-1.11-broadcast.patch in ypbind-1.12-5.21.6.src.rpm
ypbind-1.12-5.21.1.src.rpm is the latest src.rpm in the RHEL3, and that's from
This is in RHN and via up2date.
An advisory has been issued which should help the problem
described in this bug report. This report is therefore being
closed with a resolution of ERRATA. For more information
on the solution and/or where to find the updated files,
please follow the link below. You may reopen this bug report
if the solution does not work for you.
It appears that rhn didn't push out the latest rpms all at the same time. You
should have recieve ypbind-1.12-5.21.6 from up2date by now. If not please
re-open this bug.
