All too often, applications send my personal data to their server, be it the content of my address book, my location or other private data.

A unique distunguishing feature for Jolla could be a built- in network monitor similar to the "little snitch" mac application, that allows you to intercept every network request, and is very configurable. The network monitor would allow me to intercept unwanted connection attempts and to decide how to proceed. It would have realtime traffic information and powerful yet simple options for analyzing bandwidth, traffic totals, connectivity status and more.

That's something I am looking for as well! Actually I expect Sailfish to assign rights with a reasonable granularity to each and every app, e.g. address book, location data, data services, cam/mic, etc. It is important to see who is talking how often, but even more interesting what it is about. Unfortunately its often encrypted. Although a monitoring tool is more for the geeks, geeks will do the job for the common user and report their findings.

is there already a possibility to monitor network connections?

There is quite a powerful way of monitoring your network connections. In Warehouse/Openrepos enable the repository from NielDK and install the apps "redis" (section Utilities) and "ntopng" (section Network). Then start the redis server and the ntopng server (as root user, in the mentioned order):

# redis-server &
# ntopng -i wlan0 -i rmnet0 &

Now you got the classical Ntop-NG "network sniffing" engine running in the background, storing its data into redis, and you can watch the results connecting your local webbrowser to the ntop webserver port 3000: either connect to locally on your Jolla (although the screen is way too small) or connect from some external browser to your Jollas IP-Nr:3000 and enjoy.

Each parameter "-i interface-name" describes a network interface you want to sniff. Use the ifconfig command to identify yours: wlan0 stands usually for the wireless, rmnet0 for the mobile phone connection.

Of course, a native and easier to handle Sailfish app just displaying the realtime and/or historized flows like good old ntop did on the console would be greatly appreciated as well.

P.S.: in case NielDK would be reading this... thanks for all the work you do, and could you maybe actualize your ntopng package to the newest version and compile it with ip-geolocation...?

Yes, redis and ntopng is quite good (it does support GeoIP btw) I am currently building new version of both redis and ntopng (geoip is already done), You will find the builds on my pages on merproject - until I move them to openrepos later.

@melg01 On starting the second server i am getting error:

ERROR: could not open pcap file: rmnet0: No such file or directory

Also when entering into the browser i am getting an error. Cannot connect to server because its busy.

Running the first process states the port that can now accept a connection mine was 6379 and not 3000, now it connects but i am getting the following errors:

-ERR wrong number of arguments for 'get' command -ERR unknown command 'Host:' -ERR unknown command 'User-Agent:' -ERR unknown command 'Accept:' -ERR unknown command 'Accept-Language:' -ERR unknown command 'Accept-Encoding:' -ERR unknown command 'Connection:' -ERR unknown command 'Upgrade-Insecure-Requests:' -ERR unknown command 'Cache-Control:'

@Nieldk do you have more user help/ guide material. I was trying to connect using a firefox browser app on the actual phone that is running the services.

As a partial response, according to community wiki someone is working on a network monitor. IMHO the personal firewall is really a second unrelated feature.
