This is fixed in FC5, but will not be back ported to FC5. Please disable protection for ypserv, and you should be able to run. setsebool -P ypserv_disable_trans=1 |

Version-Release number of selected component (if applicable): selinux-policy-targeted-1.27.1-2.22 How reproducible: Always Steps to Reproduce: 1. Configure a FC4 NIS slave server 2. set selinux to enforcing 3. run yppush on the master server to push a map to the slave Actual Results: The push fails with: Transfer not done: RPC failure talking to server Expected Results: ypxfr on the slave should've been invoked to copy the map from the master. Additional info: ypxfr run manually on the slave works fine. With selinux in permissive mode it all works as expected. I added this as a comment to bug 172374 but since that has status CLOSED CURRENTRELEASE, I'm worried it won't be noticed.
