You want to allow machines *outside* to connect to a machine *inside* the firewall to print? Most of the time, firewalls are set to allow outgoing connections to any port... No matter. What you want to look at is /etc/services, most likely: % grep print /etc/services printer 515/tcp spooler # line printer spooler % % grep irc /etc/services irc 194/tcp # Internet Relay Chat irc 194/udp ircs 994/tcp # IRC over SSL ircs 994/udp # IRC over SSL ircd 6667/tcp # Internet Relay Chat ircd 6667/udp # Internet Relay Chat ircd-dalnet 7000/tcp # IRC - Dalnet ircd-dalnet 7000/udp # IRC - Dalnet dircproxy 57000/tcp # Detachable IRC Proxy % I believe port 6667 is what's most often used. Er, perhaps -i should be used: % grep -i print /etc/services ipp 631/tcp # Internet Printing Protocol ipp 631/udp # Internet Printing Protocol printer 515/tcp spooler # line printer spooler % -Stewart "There's also the RFCs for the relevent services" Stremler -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
