In fact I'm using some PortableApps already, so yes, I know your page - very nice work! I would personally welcome a "PortableWireshark" version, and would be willing to spend some effort for it (unfortunately, currently my time is pretty limited). BTW: We will probably not drop U3 support, unless there's a very good reason for it :-) BTW(2): The main U3 advantage I still see is the way it's closing applications - which might be added easily to PortableApps as well. There are the two tasks to make Wireshark a full "Portable App": 1) make Wireshark itself "portable" - shouldn't be too difficult as Wireshark is cleanly programmed in this regard The current U3 code leads to the places to look at. It's about finding some directories, e.g. where to find/save the users settings (usually at "c:\Documents and Settings\<username>\Application Data\Wireshark" or the corresponding international path). You might already have some solutions for this, as I guess this is a common problem for all portable apps. Some background info: - the Wireshark installer is already NSIS based - Wireshark itself won't write to the registry (the installer will only write to the registry for file extension association which can be easily ommited) - WS should be able to run with "ordinary" user privileges => Making Wireshark a ProtableApp shouldn't be too difficult. 2) make WinPcap "portable" - I don't know a good way for this (might become pretty difficult) WinPcap is the driver to capture live network data (for Wireshark and a lot of similiar tools). It seems that WinPcap must be installed in c:\winnt\system32 to work properly - at least I don't know a better way than this :-( Unfortunatly, while WinPcap itself is open source, the WinPcap installer is closed source, so there's no easy way to get an idea how to do it from sample code. This is how the U3 package handles this when the stick is plugged in: - detect if WinPcap is already installed on the system - if not, call the WinPcap setup.exe and install it on the system - when the stick is going to be unplugged and WinPcap was installed by the U3 package, ask the user if he wants to uninstall WinPcap => This obviously isn't nice, but we don't know a better way. In addition, you'll need Administrative privileges to install/start/uninstall winPcap :-( Wireshark will run without WinPcap, e.g to show previously captured data, but WinPcap is needed to capture any live network data. ----------------------------- So what I would like to know for a start: - how to distinguish if WS is running as a PA(U3 uses an environment setting)? Or is this done through a command line switch or such? - we'll need an "Application Data/Wireshark" directory somewhere on the stick - is there a "portable app recommendation" for this? - where do we get one of those fancy splash screens for Wireshark from? Might be derived from the current splash screen picture ;-) Regards, ULFL P.S.: Well, the page http://portableapps.com/development is a bit short ;-) If it would be more comprehensive, I might have started this task already a lot earlier ... _______________________________________________ Wireshark-dev mailing list [email protected] http://www.wireshark.org/mailman/listinfo/wireshark-dev
