Red Hat Bugzilla – Bug 455857
ypbind loses bind
Last modified: 2009-06-09 23:55:08 EDT
Description of problem:
We've been seeing this problem for several weeks, on machines running Fedora 8
and 9, up-to-date with ypbind-1.20.4-6.fc9.x86_64. ypbind binds to the lab
local ypserv (which happens to be quite old, running Red Hat Linux 7.2
ypserv-2.8-0.72E). But the ypbind clients lose their bind to the server
"often"; some daily, some every hour or so, some much less often.
on the ypserv, we've gotten syslog messages like this one for years, but with
seemingly no problem because of it:
ypserv: refused connect from xx.xx.xx.xx:41801 to procedure ypproc_match
A restart of ypbind on systems where it has lost bind always restores it. But
that's annoying to have to do often. There seems no rhyme or reason from a
client perspective why it might lose bind. The lab network is fully switched
gigabit ports, very lightly utilized.
still seeing this, with up-to-date Fedora 9. Any debugging I can provide, please describe what to do.
ping - this is still failing on F-9.
Well, I'm not able to reproduce it.
Older versions than ypbind-1.20.4-6 worked fine? There are only minor changes in ypbind (generally in init script), so I believe it's highly unlikely that the problem is linked to ypbind update.
ypserv message you mentioned (error code -4) AFAIK means that the map requested wasn't found, so you're right - it doesn't matter (in newer ypserv these events aren't logged).
Did you try change -ping-interval disable ping at all? Brings it some effect?
Michael Brown, can you look at ping interval? You have the nightly reproducer case.
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '9'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 9's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 9 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
I don't think I've seen this on F10. Closing.
