I don't think that you even showed anything. The only test you should do about that is to try to connect to the port, e.g. with telnet (or nmap can probably tell you). If the connection isn't immediately refused, then the Listen directive is OK. For instance: zira:~> telnet localhost 631 Trying ::1... flushoutput character is 'off'. Connected to localhost. Escape character is '^]'. Fine. And you can try the same thing from a different machine on the network, replacing "localhost" by the IP address of the server, e.g. from another machine on my network: $ telnet 192.168.1.3 631 Trying 192.168.1.3... telnet: Unable to connect to remote host: Connection refused because my CUPS server just has Listen localhost:631 Listen /var/run/cups/cups.sock If the connection is accepted with telnet by using multiple Listen directives, then the Listen configuration is correct. If you can see any other issue related to the printers, then the problem is due to something else. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
