How do I close open ports ???
Hello All,
I am using APF and iptables filrrtewall on different servers.On my local sever I use APF . When I scanned my local server for open ports I found the port 631 is open which is a tcp port using ipp service. I have tried to close the port by adding the entries in deny_host file in apf directory as: tcp:in:s=631:s=0.0.0.0 then i restarted the firewall as apf -s But still it is showing the port is open. How can i close it? |

Are you scanning the server from itself? CUPS uses the lo interface so it will pretty much always appear open locally. Try scanning from somewhere on the net, there are some good websites with java portscans out there.
If its still open globally then you could just block the port on eth0 but still accept connections from the lo interface, unless your using it as a print server, then it would be more complicated. |
