I run a web server (Debian Squeeze on a VPS), and the graphs provided by the hosting company show consistently that around twice as much traffic is incoming to the server compared to the outgoing traffic.
From this thread (http://www.tutorialarena.com/blog/check-open-ports-on-ubuntu-linux.php), I found one port of my machine is not allowed for incoming connections, that's why I cannot visit my service outside (I guess). I've checked a lot of threads to open port for incoming connection, but it didn't work anyway. The most methods I found is modify/add the iptable (here for instance.).
I am developing a application, in which incoming and outgoing calls will be recorded. I want to display incoming and outgoing call recordings in one list view and in that list view I want to show different images for incoming and outgoing because I want the user to know which is incoming and which is outgoing. So, how can I do that. Please any one can help me.
