Experimental WireShark version with user interface list and remote capture (RPCAP) support

Hi all,

Subj can be download from here. It's Win32 version.

Sorry I did not create installer version so just unpack archive to any directory and start wireshark.exe.
Local installed WinPCAP required. If you do not know how to install WinPCAP just run regular WireShark installation (0.99.6 recommended). It'll do everything needed.

If you want capture from remote Windows PC go to WinPCAP installation directory on remote PC and start rpcapd.exe. Copy from your Windows PC should also work.

To remote capture from Linux PC rpcapd should be started. Check for information how to build rpcapd for linux here.


I have compiled development version of rpcapd for FC4  (can work on other linux'es as well). Available here.

You need to use -n flag for now when rpcapd started. Read documentation (link I posted above) if have any questions on rpcapd.

After you start rpcapd, lunch my version of wireshark. Go Properties->Capture->Edit..... You'll find a way to add new remote interface.
Then go to Capture->Interfaces you'll see new interface in list. It should work as regular interface.

Any feedback very appreciated. It'll push me to clean the code and release to public.

What do you mean by "with user interface list"?  (My machine only runs a 
Win32 OS in Virtual PC, and it's a bit slow, given that my machine's 
processor isn't an x86 processor, so I don't want to download and run 
that version of Wireshark to find out.)

It appears, from the packets you sent in your other message (which 
would've been less confusing if you'd sent it as a reply to your own 
message) that the PPPoE header, as captured, is bogus; it claims that 
the payload length is 14 bytes, not 1294 bytes.

I don't know whether that's because the payload length is really wrong 
on the wire, or because the Linux PPPoE implementation just tweaks the 
PPPoE header in-place before the packet gets handed to the socket layer 
(and thus to libpcap and thus tcpdump/Wireshark/whatever program is 
capturing).

I would not be in the least surprised to find that it's the latter, as 
we've had problems with captures done on Linux before this, for the same 
reason.  I thought there was copy-on-write logic that would prevent 
modified-in-place packets from being handed to programs capturing 
traffic, but I guess it either doesn't exist or isn't being used.

Re: Experimental WireShark version with user interface list and remote capture (RPCAP) support

By User List I mean any interface describing text line. Currently WireShark showing in list only intefaces it found on local machine.
If you're using remote capture you need enter interface to capture from as string some times pretty long.
I add functionality to allow user enter it's own interface lines add save them to configuration file and load back
to WireShark after reload.

Re: Wireshark MPEG-4

Hi,
There is no dissector in Wireshark to dissect the MPEG-4 payload.

Hello everyone!

I´m new in wireshark but I would like to know if wireshark can decode
MPEG-4 streams via RTP.

Im streaming a mp4 file from vlc media player and capturing the rtp packets. Decoding the rtp packets is not a
problem. What I cant do is decode the RTP payload with the MPEG-4 data.

The RTP payload type is 96.

Any help?

Thanks

Re: Wireshark MPEG-4

Hi,
The MPEG2_TS dissector from http://network-research.org/mp2tsdis.html was never accepted into Ethereal/Wireshark as there were issues
with the code that was never fixed.

I'm interested in the answer to this question as well, but I'd like to know if anyone is using an up to date MPEG2_TS dissector?  The ones I got via hits on Google look pretty old ( network-research.org's dissector = 2004?)

Thanks,

Hardware Platform to capture SS7 traffic on TDM lines to Decode with WireShark

Hi All,

Dear friends I am new to the Wireshark community as a developer. As our final year project
we will be developing a SS7 protocol Analyzer. Here we will be developing the Hardware
Circuitry to tap a physical E1 line. We have used Dallas Maxim E1/DS1 ICs are being used to
capture the raw data and those data will be ported in to a machine using a USB IC from FTDI.

We hope to analyze the raw data we capture through WireShark. The data we capture is in the
memory and we can access them via a custom API. We hope to insert these data in to pseudo
UDP or TCP packets and analyze through WireShark.

Please instruct us how should we start about from here, asking ANY question from us. Can we know
of any documentation that is available on SS7 message decoding in WireShark, as we know it
is not there in /docs  directory.

 Also we want to know what is the starting point of dissecting the SS7 stack in the WireShark
source. We went through the dissectors included in epan especially mtp2.c and there onwards
up the stack but our impression is that for our purpose we cant start at mtp2.c since we dont
see the Frame Alignment Word of SS7 ' 01111110 ' being handled there, subsequent decoding.

Regards

Xavier

And no other choices for an MPEG2_TS dissector?

using statistics

hey,

i'm quite new to Wireshark and cant figure out how to use statistics.

i have a network trace from a service (HTTP), many client IP's talking to one server (requests/responses).
i need to know the following:

- how many concurrent HTTP sessions thru a time period (a single graph, i presume)
- how many HTTP sessions per client IP (a table, i presume).

any pointers are welcome.

thanks,
Mait

Unable to compile static build of TShark on Fedora 7

Hi, with WireShark 0.99.6, I am having trouble building TShark statically.

If I do this:
./configure --enable-static --disable-wireshark
make

I get an error about -lgmodule

However, I seem to have the appropriate libraries installed:
$ locate gmodule

If I do this:

I get
/usr/bin/ld: cannot find -lkrb5

even though:
$ rpm -qa|grep krb5
krb5-devel-1.6.1-2.1.fc7
krb5-libs-1.6.1-2.1.fc7
krb5-auth-dialog-0.7-2

How can I do a static compile of TShark?

I've also tried on Fedora 6 and RHEL4, btw.

Thanks,
Barry
