Its worth checking, so run the following command as root: netstat -apn | grep ':631' netstat shows a lot of garbage, so I've used grep to only show the IPP- related lines. If you're not running it as root you'll see '-' instead of the pid and program name: netstat has to run as root to get the name of the program using each port. On my system I see: tcp 0 0 0.0.0.0:631 0.0.0.0:* LISTEN 2523/cupsd tcp 0 0 :::631 :::* LISTEN 2523/cupsd udp 0 0 0.0.0.0:631 0.0.0.0:* 2523/cupsd which says that cups is listening on port 631 for incoming TCP/IP connections using IPV4 and IPV6 protocols and for UDP datagrams. netstat lines contain a lot more whitespace than I've shown so I edited the blanks out to make it more readable. If you've disabled IPV6 on your Mac then you'll only see the first and third of these lines. If netstat shows that cupsd (the CUPS printing service) owns port 631 then the CUPS configuration is incorrect, because it has opened the port but is ignoring any attempts to connect to it. Double check that you have CUPS configured to listen for 'internet connections' - on my Fedora 10 distro this is disabled by default. Martin
