I have RHEL5 Server originally configured and installed by me with Firewall enabled, but passing through NFS, Samba, and SSH. I then disabled SELinux. As you all likely recall, I had configured a test environment to get samba and nfs/nis up and running. I got it going, and recently brought it to a production server. After modifying the files on the production server and rebooting, I'm getting the long pause of the server trying to bind to my yp domain, then failing. When I finally was able to log in, SELinux warned me that I could get past the ypbind problem by issuing a command, which I did. I then restarted ypbind, and got a delay/timeout again. I'll check the log files tomorrow for any further hints. Is there a file I can edit to ensure SELinux is disabled? The system was initially installed with SELinux Enabled, then disabled later by me. In the meantime, I did find http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/security-guide/s1-server-nis.html and will see if that may help. I think once I get past beyond the security issues, yp will work/bind fine. Thanks for any help/insights. Scott
