[Announce] QNetMan
 

Hi all !
QNetMan (QNetworkManager) - Qt-based network manager which allows to monitor your network traffic. It is possible to record network sessions information for different connections and provide the information in graphical view.

Please let me know any bugs in the program.

Re: [Announce] QNetMan
 

Well not really a bug, but I'd lose the "of" from the "Monitor of connections" button.

Otherwise I like the way the UI is done. Need to look at the app more for the features :).

Nice work!

Re: [Announce] QNetMan
 

Hi Qnetman, I downloaded your app from extras-testing but can't get it to start up. I checked dependencies, they seem to be ok. I got PR1.3, kernel 2.6.28power42
When I start from command line this is the output I get:
/opt/maemo/usr/bin $ ./qnetman
Traceback (most recent call last):

Re: [Announce] QNetMan
 

Oh, thanks, fasza2.
It's very strange, please, run the command in the terminal
dpkg -l | grep -i pyside
and copy the output here

Re: [Announce] QNetMan
 

qnetman,

Thank you very much. May I ask you, about your program, does it start the daemons every start, or just after I launch the program? I saw that it start the daemons in event.d, so, may I ask you to put an option on the menu to remove(and put back) the daemons active now and in the startup?

This is just a suggestion, I could do it myself(remove the event.d file and killall the daemons after I've done the search of some guilty app), but as you are on it and I think you are excited, so...

Anyway, thank you again.

Re: [Announce] QNetMan
 

Thanks.
Daemon is controlled via dbus and is awaiting signals from the GUI program or operating system signals the addition / removal of network interfaces. If the daemon is not running, it will be impossible to record network traffic.
Maybe you're right, I'll do the setting, which can be managed autostart daemon. But, this configuration may cause more problems for novice users.
Sorry for my English. :(

Re: [Announce] QNetMan
 

No apologies please. You write adequate english whilst speaking natively another language. Many of us english native speakers cannot do that.

I run kernel power47 ( thanks Pali), and am having reboots, both over clocked and without. Common factor is qnetman running. Trying io or perhaps cpu intensive tasks appears the trigger eg. "apt-get update && apt-get upgrade.
At this point: anyone else running the same and not having issues?

Bugs: In viewing graphs of sessions, enlarging and scrolling should keep vertical axis with units visible.

When utilising "Monitor of connections" > "record (icon)" whilst a recording is underway, a press on the record button to stop recording has no visible effect YET it has registered the entry. Can lead to multiple (confused) presses and unintended recording.

Re: [Announce] QNetMan
 

Thank you.

Initially, the package had qnetman depending on the package python-pyside.qtcore and python-pyside.qtgui Then I replaced them with pyside-qt4-core and pyside-qt4-gui. Maybe I did not do it right?
Please try to install packages
python-pyside.qtcore and python-pyside.qtgui
Does not arise between the two conflicts?

In the description of package says that pyside-qt4-core depends on python-pyside.qtcore
Correct me if I'm wrong

Re: [Announce] QNetMan
 

It is interesting I try to spend a few such tests. What are the problems you have observed in this situation?

Oh yes, you are absolutely right, I'm sure will correct it.


Here I do not understand you little.
When recording is stopped by pressing a button, the toggle button is pushed out of position and pops up a message that the recording is stopped.
You are going to another way? :confused:

Re: [Announce] QNetMan
 

Ok, here is what I get:

However, it seems to solve the problem with qnetman.

Here is what I get now running dpkg -l | grep -i pyside:

Re: [Announce] QNetMan
 

python-pyside.qtcore seems to replace pyside-qt4-core, I did have pyside-qt4-core installed prior, but there was no sign of python-pyside.qtcore. On the link to Pyside-qt4-core 0.3.1-1maemo2 I saw no sign indicating that pyside-qt4-core depends on pyside.qtcore.

Re: [Announce] QNetMan
 

I understand that you helped to reinstall the packages. That's good. I hope this does not affect the performance of other applications.
I'll have to rebuild the package qnetman. Thank you for your help.

Re: [Announce] QNetMan
 

In the description of the package see item "Packages depending on this package: ........" and a long list of packages. Among them, there is a package pyside-qt4-core

But the version of this package Pyside-qt4-core more than the version that was you.
My fault is that I do not have version Pyside-qt4-core in my package qnetman

Re: [Announce] QNetMan
 

The first issue has the phone reboot by itself. Seems IO/CPU triggered and probably done by the warchdog daemon. I have no such problem with qnetman uninstalled.

With respect to the last issue, yes things happen as you describe except that the button takes a while to change and for the notification to appear. In other words, the button does not immediately show that it registered the touch. And that means one can touch the button again thinking it failed to register the press and then get a recording started that you do not want. Hope that is clearer.

Re: [Announce] QNetMan
 

There is some dependency issue with alarmed, but it seems to be working still, other then that it's all good.

Re: [Announce] QNetMan
 

Yes, now I understand you. I will change the source code, and this should not be happening.

Re: [Announce] QNetMan
 

Is there any way to check the details of packets sent/recived in a recorded session? I mean TCP, UDP, controll messeges, keep alive packets, etc. Its quite useable anyway, but would be interesting to see for certain websites, IM apps and VPN. :)

Re: [Announce] QNetMan
 

If you remember such detailed statistics package, you get a different program :D
I have another idea, to determine what program is trying to make a connection and display it in the window "Network Connections"

Re: [Announce] QNetMan
 

I discovered the database was corrupted. Could not delete records. Once the db was deleted and a new one made, the lag I described seems not to be there. The button does not respond to touch but the notification message appears quickly. I still however think that an immediate button response upon touch would be good.
thanks.

Re: [Announce] QNetMan
 

That is perfectly what I need. I would love that.

Re: [Announce] QNetMan
 

The delay in the touch of a button can occur only if sending a signal to dbus would be blocking. However, as far as I know, the function is not blocked.
Yet there is little opportunity to accelerate the reaction, but it's acceleration, I think it will not matter much. But I'll do it. :)
Please,tell me, database corruption has occurred due to errors in the program qnetman ? :confused:

Re: [Announce] QNetMan
 

I'm working on this idea :)

Re: [Announce] QNetMan
 

It most likely happened when the n900 rebooted whilst using qnetman. Only reason I can think of. Program then indicated it was recording but the session records never appeared and I could not delete those sessions that were there (database error message).

Re: [Announce] QNetMan
 

Kind of thought so, however the latter idea is also welcome ;)

Re: [Announce] QNetMan
 

The new version QNetMan - 0.4.0

http://qnetman.garage.maemo.org/imag...enshots/s1.png http://qnetman.garage.maemo.org/imag...enshots/s2.png

• Fixed bugs in the GUI (thanks to everyone for active discussion)
• Added more options in the interface monitoring

Please inform me of all the bugs. Thanks ;)

Re: [Announce] QNetMan
 

Hi Anatoliy, I tried your new build from devel and I ran into the same or at least simillar issue with pyside as before:
opt/qnetman $ ./qnetman.py

ii python-pyside.qtgui 1.0.3-1maemo2 Qt 4 GUI module - Python bindings

I did not manually update pyside. It either got installed by your new build or by something else from testing. (Well qnetman didn't work out of the box just after I installed so the latter is very unlikely)

Now I'm going to revert pyside back to the version that worked with your last build, I'll get back with the result in a few mins.

Re: [Announce] QNetMan
 

It's a no go :(

sudo apt-get install python-pyside.qtcore python-pyside.qtgui

python-pyside.qtgui is already the newest version.

Could you please help me out here m8? How can I force revert it in one step? I know I could just --purge it then install, but... still learning linux:) You could also enlighten me if I'm wrong about the source of the problem. ;)

Re: [Announce] QNetMan
 

It would look nicer, if you used Maemo's own icons.

Re: [Announce] QNetMan
 

:confused:

fasza2
try to update the library pyside the command
apt-get upgrade libpyside
you have installed version 0.3, but the repositories have version 1.0

Re: [Announce] QNetMan
 

But the native icon set does not contain the necessary icon themes for QNetMan

Re: [Announce] QNetMan
 

I had a guy who had the same error with my program. Try what qnetman suggests, I think that will do the trick. If it does not help, try to follow my post : http://talk.maemo.org/showpost.php?p...&postcount=134

Try to remove the old version 0.3

Re: [Announce] QNetMan
 

In version 0.5.0 QNetMan is available the widget homescreen.
http://qnetman.garage.maemo.org/imag...enshots/s3.png http://qnetman.garage.maemo.org/imag...enshots/s4.png


This is the first simple version of the widget. Work on the widget just begun. If you have ideas for development, write. ;)

Re: [Announce] QNetMan
 

Anyway apt-get upgrade libpyside fixed the problem, though I have updated to 0.4.5 from testing(it also had the same issue with pyside... on my side :) ) Thx I'll check it out now.

Re: [Announce] QNetMan
 

@Anatoliy
Checked out the widget, works like a charm. I had an idea that perhaps you could make a data counter based on your daemon. It would be much simpler then qnetman and a big portion of the work is already done. Now I don't know there is anything useful out there in the repos, since I don't really need it, but last time I checked there was only 1 package that was counting home data as gprs0+eth0 which doesn't help much determing wether you are within your data plan. If you're interested I could look around for data counter apps and check if really there is a need for it, saving you the time ;)

Re: [Announce] QNetMan
 

Widget works really well and frankly makes the whole use of qnetman a breeze.
One thing: if one can choose between bar and line graph in the monitor function, the same should reflect in the historical usage graphs or should be a choice there too.

Re: [Announce] QNetMan
 

Thanks all. Functional widget must be expanded. :)

If I understood you correctly, then I can add the daemon to track the number of consumed traffic from a specific point in time. If the value exceeds the threshold, notify the user. Right?

A little later I'll do it ;)

Re: [Announce] QNetMan
 

Exactly, just remember that user needs to be able to set the date of count reset and the amount of the threshold. You could keep it rather simple.

Regarding your widget the only improvement I could think of is to add a record button to each 'line' so that user don't have to fire up qnetman just to start/stop recording a session. Other then that it's good enough for me(BTW love the click to refresh option). Feedback of others on this idea is welcome.

Ps: you could add a link for donate as well(both app&homepage) I'm sure if peeps are willing to throw some money at you that can't hurt ;)

Re: [Announce] QNetMan
 

Yes, it's really a good idea :) thanks

I'll think about how this can be done

I like your ideas :)
