Running an NIS server on CentOS 7 for about a year and previous versions of CentOS or RHEL for over a decade. Today things stopped working. None of my machines can connect to the NIS server and it seems to be a problem with ypbind. Red Hat Bugzilla – Bug 1415496 seems to describe the problem but their solution is not working for me since it is for Fedora and I am running CentOS.
The following are commands I have run to try to identify the problem. My Google foo does not seem to work when trying to use some of the errors below. Any suggestions? Bruce # systemctl restart ypbind.service Job for ypbind.service failed because the control process exited with error code.
