RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Red Hat Product Errata RHBA-2015:1332 0 normal SHIPPED_LIVE ypbind bug fix and enhancement update 2015-07-20 17:52:51 UTC

Description Konstantin Olchanski 2012-06-06 21:22:07 UTC 
ypbind does not bind to ypserv on localhost (same machine) if NetworkManager thinks that the network is off. This is surprising behaviour. One solution is use "ypbind -no-dbus", then ypbind binds to local ypserv correctly and NIS works as expected. Perhaps this should be the default configuration, matching the traditional UNIX behaviour of NIS tools.

ypbind-1.20.4-29.el6.x86_64

K.O.

With this patch ypbind won't go offline when one of the servers is localhost.
Comment 3 Konstantin Olchanski 2012-07-09 17:48:42 UTC 
I happened to look at the patch. The check is for IP address 127.0.0.1, correct for typical use, but remember than all 127.x.y.z IP addresses are localhost. K.O.

Thanks for pointing to that, enhanced patch is attached.

This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
