Hi, has anyone here tried to capture a VOIP traffic from a Linksys VOIP Router,
we tried using the wireshark but it seem it doesnt recognized the captured
packet,
wireshark can display the protocols used. Hope you can enlighten me. Thanks.

Hi,
Right now we are using tshark for capturing packets on our network and use it
to translate, it seem theres a lot of packet loss.
Is it possible to dissect or parse a captured packet for VOIP since some of its
succeding packets were eventually lost, we
have found some TPKT and Q.931 protocol
Hi anders,
How do I attached the sample files? Can I put it on as wireshark verbose? Pls
see below files. Thanks

thing how can I parse a voip call (h323 family, SIP, IAX etc.) Is
wireshark capable of doing it.
Yes.
Can somebody send me a source code for parsing voip call in C language.

The lowest-layer Ethernet header is always 14-bytes long - 6 bytes of

Hi,
Right now we are using tshark in capturing packets, some SIP calls were not
displayed properly like the data shows http & etc.
Then we notice that some protocols know to ethereal were not displayed by
wireshark. What could be the cause?

Hi,
Is there someone out there who has tried filtering h323 voip calls and can you
help me with it. Thanks and more power..

Hi Jaap,
Well actually were using a Red Hat Linux and capturing packets using tshark, I
dont know if tshark can do it on large files, we're trying to iliminate the GUI
since
it lags, so how can we filter h323 calls what are the filtering parameters.
Thanks

Hi, Can tshark or wireshark show h323 VOIP calls. Were trying to filter h245 &
h225 but we cant seem to find the callee and called number.
Have you tried it. Thanks

Hi Stu,
So you have captured a large data of 16Gb, is it from a large network? What is
the average xx Mb/sec Iam also using tcpdump and tshark to capture large files
our network has an average traffic of 500Mb/sec so what specs are you using in
capturing such large files. Thanks

Thanks for the response, yup I know that wireshark or ethereal cant handle
large amount of data, so does tcpdump and dumpcap capable of handling such
data, can we use it to capture large amount of data, save it to multiple files
for Tshark or Tethereal for post process. Pls advise and thanks
Sebastien Tandel,
Thanks for the info, yup we already tried it but it seems it doesnt work. What
we are trying to do is capture packets and save it in another file
where tshark or tethereal process it, we tried using tcpdump or dumpcap but it
doesnt work, the network is relatively high about
Hi,
Is there someone here who has tried using tcpdump or dumpcap in capturing
packets on a GigE interface, we tried to run it but the system freezes. Is
there a way we can use it to capture data. Below are the command we use in
capturing data. BTW we are using Sun Solaris9 Sparc (blade 1000).
Hi jeff,
Thanks for the info, is there a way we can capture such traffic aside from
wireshark, then we would dissect it in
another box or like capture packets then save it in another file like multiple
files before we dissect it. Thanks

Hi,
Actualy we are planning to use wireshark on a large network so we could further
study IP Packtes.
Can wireshark support our needs. Thanks and more power.

Hi,
Currently we have already installed the ethereal software for our Solaris9
Sparc, but the problem is the blade server shuts down.
The scenaio is:
1. We captured sample packets using tethereal with xx bytes.
2. then after analyzing the data, we tried capturing specific no. of bytes i.e.
Hi gerald,
Well, Im running it on a Solaris9 sparc. Can I use the wireshark instead, but I
cant find a stable or an installer for Solaris9
Hope you can help me with this. Thanks

Hi,
Im using ethereal for capturing IP packets and the platform we used is Linux
Enterprise, when we try to display the decode like on the frame it shows the ff.
My problem is when we load it in a Sun Solaris platform the Protocols in frame
is not present. Can somebody help me with this? What
