INDEX
1. General Questions:
1.1 Where can I get help?
1.2 How much does Ethereal cost?
1.3 Can I use Ethereal commercially?
1.4 Can I use Ethereal as part of my commercial product?
1.5 What protocols are currently supported?
1.6 Are there any plans to support {your favorite protocol}?
1.7 Can Ethereal read capture files from {your favorite network analyzer}?
1.8 What devices can Ethereal use to capture packets?
1.9 How do you pronounce Ethereal? Where did the name come from?
2. Downloading Ethereal:
2.1 I downloaded the Win32 installer, but when I try to run it, I get an
error.
2.2 When I try to download the WinPcap driver and library, I can't get to
the WinPcap Web site.
3. Installing Ethereal:
3.1 I installed an Ethereal RPM, but Ethereal doesn't seem to be installed;
only Tethereal is installed.
4. Building Ethereal:
4.1 The configure script can't find pcap.h or bpf.h, but I have libpcap
installed.
4.2 Why do I get the error
dftest_DEPENDENCIES was already defined in condition TRUE, which implies
condition HAVE_PLUGINS_TRUE
when I try to build Ethereal from SVN or a SVN snapshot?
4.3 The link fails with a number of "Output line too long." messages
followed by linker errors.
4.4 The link fails on Solaris because plugin_list is undefined.
4.5 The build fails on Windows because of conflicts between winsock.h and
winsock2.h.
5. Using Ethereal:
5.1 When I use Ethereal to capture packets, I see only packets to and from
my machine, or I'm not seeing all the traffic I'm expecting to see from or
to the machine I'm trying to monitor.
5.2 I can't see any TCP packets other than packets to and from my machine,
even though another analyzer on the network sees those packets.
5.3 I'm only seeing ARP packets when I try to capture traffic.
5.4 I'm running Ethereal on Windows; why does some network interface on my
machine not show up in the list of interfaces in the "Interface:" field in
the dialog box popped up by "Capture->Start", and/or why does Ethereal give
me an error if I try to capture on that interface?
5.5 I'm running Ethereal on Windows; why do no network interfaces show up in
the list of interfaces in the "Interface:" field in the dialog box popped up
by "Capture->Start"?
5.6 I'm running Ethereal on Windows; why doesn't my serial port/ADSL
modem/ISDN modem show up in the list of interfaces in the "Interface:" field
in the dialog box popped up by "Capture->Start"?
5.7 I'm running Ethereal on a UNIX-flavored OS; why does some network
interface on my machine not show up in the list of interfaces in the
"Interface:" field in the dialog box popped up by "Capture->Start", and/or
why does Ethereal give me an error if I try to capture on that interface?
5.8 I'm running Ethereal on a UNIX-flavored OS; why do no network interfaces
show up in the list of interfaces in the "Interface:" field in the dialog
box popped up by "Capture->Start"?
5.9 Can Ethereal capture on (my T1/E1 line, SS7 links, etc.)?
5.10 How do I put an interface into promiscuous mode?
5.11 I can set a display filter just fine, but capture filters don't work.
5.12 I'm entering valid capture filters, but I still get "parse error"
errors.
5.13 I saved a filter and tried to use its name to filter the display, but I
got an "Unexpected end of filter string" error.
5.14 Why am I seeing lots of packets with incorrect TCP checksums?
5.15 I've just installed Ethereal, and the traffic on my local LAN is
boring.
5.16 When I run Ethereal on Solaris 8, it dies with a Bus Error when I start
it.
5.17 When I run Ethereal, I get an error
Gtk-CRITICAL **: file gtkwindow.c: line 3107 (gtk_window_resize):
assertion `height > 0' failed.
5.18 When I run Tethereal with the "-x" option, it crashes with an error
"** ERROR **: file print.c: line 691 (print_line): should not be reached.
5.19 When I run Ethereal on Windows NT, it dies with a Dr. Watson error,
reporting an "Integer division by zero" exception, when I start it.
5.20 When I try to run Ethereal, it complains about sprint_realloc_objid
being undefined.
5.21 I'm running Ethereal on Linux; why do my time stamps have only 100ms
resolution, rather than 1us resolution?
5.22 I'm capturing packets on {Windows 95, Windows 98, Windows Me}; why are
the time stamps on packets wrong?
5.23 When I try to run Ethereal on Windows, it fails to run because it can't
find packet.dll.
5.24 I'm running Ethereal on Windows NT 4.0/Windows 2000/Windows XP/Windows
Server 2003; my machine has a PPP (dial-up POTS, ISDN, etc.) interface, and
it shows up in the "Interface" item in the "Capture Options" dialog box. Why
can no packets be sent on or received from that network while I'm trying to
capture traffic on that interface?
5.25 I'm running Ethereal on Windows 95/98/Me, on a machine with more than
one network adapter of the same type; Ethereal shows all of those adapters
with the same name, but I can't use any of those adapters other than the
first one.
5.26 I'm running Ethereal on Windows, and I'm not seeing any traffic being
sent by the machine running Ethereal.
5.27 I'm trying to capture traffic but I'm not seeing any.
5.28 I have an XXX network card on my machine; if I try to capture on it, my
machine crashes or resets itself.
5.29 My machine crashes or resets itself when I select "Start" from the
"Capture" menu or select "Preferences" from the "Edit" menu.
5.30 Does Ethereal work on Windows Me?
5.31 Does Ethereal work on Windows XP?
5.32 Why doesn't Ethereal correctly identify RTP packets? It shows them only
as UDP.
5.33 Why doesn't Ethereal show Yahoo Messenger packets in captures that
contain Yahoo Messenger traffic?
5.34 Why do I get the error
Gdk-ERROR **: Palettized display (256-colour) mode not supported on
Windows.
aborting....
when I try to run Ethereal on Windows?
5.35 When I capture on Windows in promiscuous mode, I can see packets other
than those sent to or from my machine; however, those packets show up with a
"Short Frame" indication, unlike packets to or from my machine. What should
I do to arrange that I see those packets in their entirety?
5.36 I'm capturing packets on a machine on a VLAN; why don't the packets I'm
capturing have VLAN tags?
5.37 How can I capture raw 802.11 frames, including non-data (management,
beacon) frames?
5.38 How do I capture on an 802.11 device in monitor mode?
5.39 I'm trying to capture 802.11 traffic on Windows; why am I not seeing
any packets?
5.40 I'm trying to capture 802.11 traffic on Windows; why am I seeing
packets received by the machine on which I'm capturing traffic, but not
packets sent by that machine?
5.41 How can I capture packets with CRC errors?
5.42 How can I capture entire frames, including the FCS?
5.43 Why does Ethereal hang after I stop a capture?

anywhere in them?
5.45 How do I filter a capture to see traffic for virus XXX?
1. General Questions
Q 1.1: Where can I get help?
A: Support is available on the ethereal-users mailing list. Subscription
information and archives for all of Ethereal's mailing lists can be found at
http://www.ethereal.com/lists
Q 1.2: How much does Ethereal cost?
A: Ethereal is "free software"; you can download it without paying any
license fee. The version of Ethereal you download isn't a "demo" version,
with limitations not present in a "full" version; it is the full version.
The license under which Ethereal is issued is the GNU General Public
License. See the GNU GPL FAQ for some more information.
Q 1.3: Can I use Ethereal commercially?
A: Yes, if, for example, you mean "I work for a commercial organization; can
I use Ethereal to capture and analyze network traffic in our company's
networks or in our customer's networks?"
If you mean "Can I use Ethereal as part of my commercial product?", see the
next entry in the FAQ.
Q 1.4: Can I use Ethereal as part of my commercial product?
A: As noted, Ethereal is licensed under the GNU General Public License. The
GPL imposes conditions on your use of GPL'ed code in your own products; you
cannot, for example, make a "derived work" from Ethereal, by making
modifications to it, and then sell the resulting derived work and not allow
recipients to give away the resulting work. You must also make the changes
you've made to the Ethereal source available to all recipients of your
modified version; those changes must also be licensed under the terms of the
GPL. See the GPL FAQ for more details; in particular, note the answer to the
question about modifying a GPLed program and selling it commercially, and
the question about linking GPLed code with other code to make a proprietary
program.
You can combine a GPLed program such as Ethereal and a commercial program as
long as they communicate "at arm's length", as per this item in the GPL FAQ.
Q 1.5: What protocols are currently supported?
A: There are currently 706 supported protocols and media, listed below.
Descriptions can be found in the ethereal(1) man page.

Q 1.6: Are there any plans to support {your favorite protocol}?
A: Support for particular protocols is added to Ethereal as a result of
people contributing that support; no formal plans for adding support for
particular protocols in particular future releases exist.
Q 1.7: Can Ethereal read capture files from {your favorite network
analyzer}?
A: Support for particular protocols is added to Ethereal as a result of
people contributing that support; no formal plans for adding support for
particular protocols in particular future releases exist.
If a network analyzer writes out files in a format already supported by
Ethereal (e.g., in libpcap format), Ethereal may already be able to read
them, unless the analyzer has added its own proprietary extensions to that
format.
If a network analyzer writes out files in its own format, or has added
proprietary extensions to another format, in order to make Ethereal read
captures from that network analyzer, we would either have to have a
specification for the file format, or the extensions, sufficient to give us
enough information to read the parts of the file relevant to Ethereal, or
would need at least one capture file in that format AND a detailed textual
analysis of the packets in that capture file (showing packet time stamps,
packet lengths, and the top-level packet header) in order to
reverse-engineer the file format.
Note that there is no guarantee that we will be able to reverse-engineer a
capture file format.
Q 1.8: What devices can Ethereal use to capture packets?
