I am having no luck getting NIS to work on a clean install of CentOS 6. It seems to be an issue with ypbind. I have simple /etc/yp.conf which explicitly sets the server domain myDomain server myServer The service seems to start okay #service ypbind start Starting NIS service: [OK] Binding NIS service: … [OK] But when I try to use any of the yp services, like ypwhich #ypwhich ypwhich: Can't communicate with ypbind This is usually blamed on ypbind not running, but ypbind is confirmed to be running #ps -ef | grep ypbind root 3033 1 0 15:11 ? 00:00:00 /usr/sbin/ypbind ypcat also does not work #ypcat netgroup No such map net group. Reason: Can't bind to the server which serves this domain I have double checked that the server is running #rpcinfo -u myServer ypserv program 100004 version 1 ready and waiting program 100004 version 2 ready and waiting The domain name seems to be set correctly as well #domainname myDomain I have tried disabling iptables and selinux, but that has no effect. I am probably missing something obvious, but NIS has never given me these issues before. Any suggestions on what might be the culprit?
