Did you enable remote administration using system-config-printer? If not, it won't listen on any non-lo network interfaces.
I didn't find remote administration in system-config-printer. :-( But after I have turned sharing of queue on, I get: #nmap -6 ipv6srot6 Starting Nmap 4.03 ( http://www.insecure.org/nmap/ ) at 2006-07-19 16:56 CEST Interesting ports on ipv6srot6.ipv6.redhat.usu (fec0::f101:210:5aff:fed5:7e33): (The 1668 ports scanned but not shown below are in state: closed) PORT STATE SERVICE 21/tcp open ftp 22/tcp open ssh 53/tcp open domain 80/tcp open http 443/tcp open https 631/tcp open ipp I printed test page from my box via ipv6srot6 using ipp and everything worked alright. The only problem is: # links http://ipv6srot:631 - success # links http://ipv6srot6:631 - 403 Forbidden
