ethereal-users
i use the sniffer(ver is 4.70.04) to capture packages from two ip access gateway. and use ethereal to watch it.
but i only see the protocol fro Q931. why not see the rtp/rtcp, h323, h245 and so. if i want to see these protocol. how can i do .
thank you very much.

Hi,
I tried to download necessary stuff to my pc (win95) in order to run
ethereal.
But I couldn't make it work. I followed the instructions from your
website. Could
you enlighten me what else I need to do to make it work?
I downloaded the following packages:
Packet95.exe
ethereal-0.8.12-capture.zip
gtk-libs-20000805.zip
gimp-dev-20001023.zip
gimp-setup-20001023.zip

Looking forward to your reply. Thanks!

One thing you need to do is to tell us what it does instead of working.
:-)

I.e., there are probably many different ways in which it could fail to
work, and the cause of the problem and the fix for the problem will be
different for the different ways in which it's failing.

> I downloaded the following packages:
> Packet95.exe

The instructions for that are on the WinPcap Web site; you first have to
run the "Packet95.exe" file, as per

http://netgroup-serv.polito.it/winpcap/install/Default.htm

which says it's an auto-decompressing file. It will pop up a dialog box
to let you specify into which the files are to be unzipped; remember the
pathname of the directory it displays (or choose another directory and
remember that pathname). Then click "Unzip"; it should say it's
unzipped 3 files, then click "OK" on the "3 file(s) unzipped
successfully" dialog box, and click "Close" on the main dialog box.

The subsequent instructions can be found at

http://netgroup-serv.polito.it/winpcap/install/help/95.htm

Follow those instructions; in step 4, you will specify the name of the
directory into which the files were extracted, from above.

NOTE: apparently you must use "old-style" 8.3 file names, not long file
names, here; when I ran the "Packet95.exe" on Windows 2000, the pathname
was an 8.3 file name, not the real long name for the directory in
question - always use the 8.3 name.

Step 6, at the end, says "At this point select OK and reboot the
machine.", with "reboot the machine" in boldface; rebooting the machine
is an important step, as the packet capture driver will *NOT* be
available to applications such as Ethereal until the machine is
rebooted!

> ethereal-0.8.12-capture.zip
> gtk-libs-20000805.zip
> gimp-dev-20001023.zip
> gimp-setup-20001023.zip

There's not much in the way of instructions on the Ethereal Web site
page at

http://www.ethereal.com/distribution/win32/

The page at

http://www.gimp.org/~tml/gimp/win32//downloads-20001023.html

gives instructions on how to install the GIMP - and its libraries -
using the "gimp-setup-20001023.zip" file. It's a Zip archive, so you'll
need an unzip program; it contains only one file, which you run, and
which will install GIMP.

The "gimp-dev-20001023.zip" stuff is, as far as I know, necessary only
if you plan to develop GIMP plugins, or other software using GTK+ and
GLib, e.g. if you plan to add new code to Ethereal. If you only want to
*run* Ethereal or the GIMP, I don't think it's necessary.

However, I don't know whether Ethereal works with the newer versions
(2000-10-23) of the GTK+/GLib libraries; you might want to consider
installing the 2000-08-05 versions instead, as Ethereal is built with
those versions.

To do that, I would suggest making a directory "Ethereal" under
"C:\Program Files", and unzipping the "ethereal-0.8.12-capture.zip" and
"gtk-libs-20000805.zip" files into that directory. This will create an
"ethereal-0.8.12-capture" directory in the "Ethereal" directory; move
all the files from that directory to the "Ethereal" directory, and
remove the "ethereal-0.8.12-capture" directory.

You should now be able to run Ethereal from the "Program Files\Ethereal"
directory; creating a desktop shortcut that runs
"C:\Program Files\Ethereal\ethereal.exe" will let you launch Ethereal
from your desktop.

Probably because there's something wrong with the pathname construction
code, at least on Windows.

I didn't have that precise problem; I fired up Ethereal once, added a
new display filter, and it saved it OK, but I then fired it up again,
deleted the new display filter, and when I tried to save it the dialog
box was

Could not save to your display filter file "": File exists.

I also had problems saving capture files.

...which may be the result of a bug in the "save_filter_list()" routine,
wherein it stores through a pointer argument a pointer to the pathname
of the filter file it was trying to save, and then frees the pathname
string, so its caller, when it tries to use that pathname in an error
message, may get junk from it.

That wouldn't explain the error, but it would explain the bogus file
name in the dialog box.

The "File exists" problem is a result of Win32 apparently not having a
UNIX-style atomic rename operation, and "rename()", instead, using
"MoveFile()", which fails, rather than removing the target, if the
target exists.

I've checked in a change that should fix this; it'll show up in the next
release.

I'm having problems with this as well.

Ethereal will not parse the fragment above,
and I can't figure out how to capture filters
to avoid seeing more frames like this.

That version is very old. I suggest that you go to
www.ethereal.com/distribution/win32 to download the
wind32-README.txt and ethereal-setup-0.8.19.exe.
This executable will do the install for you. Be sure
to read win32-README.txt because you will have to
install WinPcap to capture traffic on you network.

Don't be fooled by the ".exe" - for some reason, either IBM or the folks
maintaining the archive of binary packages for AIX stick ".exe" at the
end of the file name of UNIX-by-God executables. (Well, AIX
executables, anyway.)

I.e., he's running AIX, not Windows, as per

> I downloaded the binary files for ethereal,gtk+,glib
> and libpcap from the aix web site.

and

> I installed them using smit.
^^^^
I vaguely remember seeing some indication on that site that the ".exe"
files are binaries you run to install the software (speaking of "shades
of Windows"...); I assume from

> The ethereal is now installed

that he's already run the file and gotten Ethereal installed. (If not,
he should read the directions on the site, which presumably tell you
what to do with the ".exe" file).

After that, well, he should go to

http://www.ns.aus.com/ethereal/user-guide/book1.html

and start reading (it's even for 0.8.11...).

I don't know if any more recent versions of Ethereal are available in
binary form for AIX; if not, if he wants to run a newer version, he'll
have to get the source and compile it.

(Richard, should we put a link to the User's Guide on the Ethereal site,
or would that end up /.-ing your site? Should we put the user's guide on
the Ethereal site itself at some point, now that its source appears to
be in the ethereal-doc CVS tree?)

It's a string.

What the valid strings are depends on the OS on which you're running.

On most UNIXes, "ifconfig -a" should show you the list of interfaces,
although not all of those interfaces will necessarily support packet
capture (e.g., you can't capture on loopback devices such as "lo0" on
SunOS 5.x).

The "Interface" field is a combo box; selecting the arrow-pointing-down
widget next to the text box should drop down a list of all the
interfaces that Ethereal knows about and that it can open for capturing.

There are many good books on TCP/IP, and I'm sure people will suggest their
own favorites, but the RFCs have everything you really need to know and
they're free.
Do a web search for:
RFC791.txt for IP
RFC768.txt for UDP
RFC793.txt for TCP

I found them at http://ns.utcru.sk/pub/doc/rfc/

Rick, Guy,

Sorry. I have no router. My box is directly connected
to the cablemodem. Before, I was only trying to imply
that I was the only user connected to a hub, which was
connected to a router to which another hub was
connected to which other users were connected,
something like this:

MyBox->Cablemodem->tvCable->Hub->Router
...and from that same Router:
Router->Hub->tvCable->OtherCableModemsInMySubnet
...so, if it is true that I am the only one in my area
(on the local cablemodem "hub", wherever it is), and
that hub was connected to a Router, which was
connected to other hubs, each of which was connected
to zero or more Cablemodems, would that explain the
results I sent in my original email?

Look at tethereal's '-V' option.

The command is

tethereal -r {capture file name} >{text file name}

where "{capture file name}" is the name of the capture file you're
reading, and "{text file name}" is the name of the file to which you
want the text output to be written.

That will write the summary output (one line per packet). If you want
the detailed output, then, as noted by another poster, use the "-V"
flag:

tethereal -V -r {capture file name} >{text file name}

No, because its dissector is a "heuristic" dissector - i.e., Ethereal
doesn't recognize iSCSI traffic based on the port number, it recognizes
it based on whether the iSCSI dissector thinks a packet contains iSCSI
traffic or not.

> Is there some way to decode with iscsi?

Yes - get a capture that contains iSCSI traffic that the iSCSI dissector
recognizes as such.

If you have a capture with iSCSI traffic that's *not* being dissected as
iSCSI, you'd have to send us the capture (or send Mark Burton, the
author of the iSCSI dissector, the capture) so we (or he) can figure out
why the iSCSI dissector isn't recognizing the traffic as iSCSI.

I understand that it doesn't recognize it as iSCSI when I first read in the
capture file because we are using a different port number. However, I
thought I could force it to "Decode As" whatever protocol I wanted. But,
iSCSI does not appear in my "Decode As" list.

Thank you for assistance,

Ade,

I'm not quite sure what you mean by "trigger".
* If your "interesting" trigger can be descibed using a capture filter
(using the TCPdump syntax). Then yes. Read the tcpdump man page for more on
capture filters.


* If your "interesting" trigger can be described using a display filter,
then when you set up your trace select the best capture filter you can. Also
select "update packet list in real time". When the trace begins enter your
display filter and click apply. Ethereal will then only display your
interesting traffic. Read the ethereal documentation for more on display
filters.

* If your capture filter is too broad for Ethereal to keep up with holding
all this in memory. You can try using tethereal with the -R flag to do
pretty much the same thing, except you can only look at the trace
afterwards.
tethereal -f "ip host 1.2.3.4" -R "icmp" -w splat.trc
If you want to check the data without stopping the trace. Then use the "Use
Ring Buffer" option with a suitable capture file rotation speed. Then run
the above command on the traces that

* If your "interesting" trigger can't be described using a display filter,
your still not shot. With a bit of Perl you can scan the output of tetheral
-V or tetheral -x, and then decide which frames are "interesting". Then use
EditCap to select only those frames.

I assume by "trigger" he means what it means (from what I remember) in
some other packet analyzers, namely a Boolean expression that tests the
contents of packets, and that causes packets to start to be saved when a
packet for which the expression is true is seen.

That would be used in a case where "interesting" traffic is defined as
"traffic following a packet of a particular type".

Ah..., I see the problem. Although I've never wanted this in the past I can
see it has it's uses. Being the tethereal/perl fan that I am, I've worked up
a skeleton script which can parse tethereal -x and provide a hook into
almost any boolean expression you'd like.

Suppose you wanted to find which user opened a certain file on an NT file
server. You set up a trace of all traffic to the server using a ring buffer.
When each ring buffer file is complete you parse the output of tethereal -x
on the file to see if the text "weird_application.exe" was in a SMB frame.
If found, then you editcap out the good stuff.

Not exactly elegant. But it solves the problem without resorting to
kilo-dollar software :-)

A quick way is to use the Display Filter to only display the packets you
are interested in. Then choose Protocol Hierarchy Statistics from the
Tools menu. It will total up all the packets in the display under the
Frame category

Hi, All!

I write an application that uses low-level NetBIOS packets. When
I send NetBIOS Session Message Packet Request (NBS request), I receive
NetBIOS Session Message Packet Response (NBS response). The NBS response
consists of several parts (the first response packet + NBS Continual
Message Packets). It seems that Ethereal detects all NBS packets
correctly. What is a method to detect the total amount of NBS Continual
Message Packets or the total size (in bytes) of these packets?
