[root at webserver ~]# netstat -n -l -p | grep 631 tcp 0 0 ::1:631 :::* LISTEN 6941/cupsd udp 0 0 0.0.0.0:631 0.0.0.0:* 6941/cupsd Looks like cups has it and cups.sock does exist in /var/run/cups.

Remember something there are no two machines ever alike! Of course you are right about no two machines being identical. I did as requested and copied the working config file to the non working box with no change. Port 631 still closed. I also ran nmap against the apparently closed port with the -P0 option and it shows "closed" as distinguished from filtered. Thanks for the suggestions. B.J.
