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.

Created attachment 597046 [details] patch consulted with upstream 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.

How to reproduce: 1. configure ypbind to bind to localhost 2. turn off all networks in NetworkManager except localhost 3. service ypbind start 4. echo $? Actual results: 1 ypbind doesn't work Expected results: 0 ypbind works
