Hi,
I've successfully statically built tethereal before on linux, but
when I tried with tshark/wireshark 0.99.5, I keep getting errors like
this:
can't find -lgmodule

I've tried
--enable-static --disable-wireshark --enable-tshark --disable-gtk2
and lots of other options to configure, with no success.
(configure seems to work OK, but make fails.)

I just want to get a static build of tshark.

This is on Fedora Core 6; I also tried on RHEL4.

I do have glib and gtk and gmodule, etc.

Thanks!
Barry

What I meant was, I want to capture traffic during 'WebCam/Video
conversation', ie when i have video-convesation w/ my friend or someone.
using msn messnger webcam feature.

there is equipment that we are trying to release in public, which allows
to
have video conversation, it's something like video-telephone.
when i use this equipment, and wireshark, i can capture traffic with a
protocol ; H.263. and..G.722 , etc.
and it also tells me about their video type(qcif, cif ...), codec, and
bit-rate, picture type, etc

but i cannot capture any of these things with msn messenger video
conversation, is it b/c it's encrypted?
all i see was just 'udp' protocol saying nothing..

is there anyway that i can see and analyze these things?

I want to see their picture coding type(i-frame, p-frame), time for
receiving each frame so i can calculate their frame rates, and so on...

I also tryed with SKYPE, but i know that it uses their own codec, so there
is no way to capture video frames, and analyze them.
but as far as i know, msn messnger uses standard codec, so it can co-work
with other messngers like yahoo or AOL..

I don't know whether you understand what i am trying to say, but i hope
so..

cheers.. need help here..
plz tell me about other tools or some kind of dissectos that allow me to
do
these things..

[Wireshark-users] Bizarre mail issue on network, Please someone, help.

2007-04-18 Thread S R

Hello!

I was wondering if someone would be so kind as to help me in figuring out a
strange mail problem I'm having.  I'm having a ton of retransmissions with
mail, and it's sitting it the queue on my relay server.  I thought at first
it was some problem with my firewalls, but I'm starting to think that's not
the case.  I've run a capture on my relay server, and I'm starting to think
it may be something with my switch/router something in between - and
perhaps these messages aren't even making it to the firewall.

I'm having some problems interpreting this log, but it appears at times that
I'm not getting an ACK from my router, so I retransmit, which continues for
2 days until the timeout and the msg bounces with a rejection notice.

However, it's even more bizarre because I haven't located any packet loss.
I don't think it's an MTU problem, and the only time I can replicate the
email issue is by attempting to send .html attachments (not embedded)  They
aren't being received inbound and not reaching the recipient outbound.

This is a major issue, as it's backing up my queues, and we have some
applications that mail html attachments for reporting, etc.

Can anyone help me? I have dissected about everything I can think of.  There
are no rules on my Firewalls to prevent any attachments, no filtering is
turned on with my mail server or firewall.

TIA!!  I hope you all can find it in your heart to help me retain my sanity.
