Guy Harris f54de620d6 From Stephen Fisher: add more information on configuring for BSD,
modernize the section on BPF (modern BSDs have BPF built in and clone
BPF devices, so no configuration should be necessary; we can add back
the old instructions if people using older BSDs run into problems), and
add information on making BPF devices available to non-root users.

General Information
------- -----------

Wireshark is a network traffic analyzer, or "sniffer", for Unix and
Unix-like operating systems.  It uses GTK+, a graphical user interface
library, and libpcap, a packet capture and filtering library.

The Wireshark distribution also comes with Tshark, which is a
line-oriented sniffer (similar to Sun's snoop, or tcpdump) that uses the
same dissection, capture-file reading and writing, and packet filtering
code as Wireshark, and with editcap, which is a program to read capture
files and write the packets from that capture file, possibly in a
different capture file format, and with some packets possibly removed
from the capture.

The official home of Wireshark is


The latest distribution can be found in the subdirectory



Wireshark is known to compile and run on the following systems:

  - Linux (2.0 and later kernels, various distributions)
  - Solaris (2.5.1 and later)
  - FreeBSD (2.2.5 and later)
  - NetBSD
  - OpenBSD
  - Mac OS X (10.2 and later)
  - HP-UX (10.20, 11.00, 11.11)
  - Sequent PTX v4.4.5  (Nick Williams <njw@sequent.com>)
  - Tru64 UNIX (formerly Digital UNIX) (3.2 and later)
  - Irix (6.5)
  - AIX (4.3.2, with a bit of work)
  - Win32 (98, NT, 2000, XP)

and possibly on other versions of those OSes.  It should run on other
Unix-ish systems without too much trouble.

NOTE: the Makefile appears to depend on GNU "make"; it doesn't appear to
work with the "make" that comes with Solaris 7 nor the BSD "make".
Perl is also needed to create the man page.

If you decide to modify the yacc grammar or lex scanner, then
you need "flex" - it cannot be built with vanilla "lex" -
and either "bison" or the Berkeley "yacc". Your flex
version must be 2.5.1 or greater. Check this with 'flex -V'.

If you decide to modify the NetWare Core Protocol dissector, you
will need python, as the data for packet types is stored in a python
script, ncp2222.py.

You must therefore install Perl, GNU "make", "flex", and either "bison" or
Berkeley "yacc" on systems that lack them.

Full installation instructions can be found in the INSTALL file.
See also the appropriate README.<OS> files for OS-specific installation


In order to capture packets from the network, you need to be running as
root, or have access to the appropriate entry under /dev if your system
is so inclined (BSD-derived systems, and systems such as Solaris and
HP-UX that support DLPI, typically fall into this category).  Although
it might be tempting to make the Wireshark executable setuid root, please
don't - alpha code is by nature not very robust, and liable to contain
security holes.

Please consult the man page for a description of each command-line
option and interface feature.

Multiple File Types

The wiretap library is a packet-capture library currently under
development parallel to wireshark.  In the future it is hoped that
wiretap will have more features than libpcap, but wiretap is still in
its infancy. However, wiretap is used in wireshark for its ability
to read multiple file types. You can read the following file

libpcap (tcpdump -w, etc.) - this is Wireshark's native format
snoop and atmsnoop
Shomiti/Finisar Surveyor
Novell LANalyzer
Network General/Network Associates DOS-based Sniffer (compressed and
Microsoft Network Monitor
AIX's iptrace
Cinco Networks NetXRray
Network Associates Windows-based Sniffer
AG Group/WildPackets EtherPeek/TokenPeek/AiroPeek/EtherHelp
Lucent/Ascend access products
HP-UX's nettl
Toshiba's ISDN routers
ISDN4BSD "i4btrace" utility
Cisco Secure Intrustion Detection System iplogging facility
pppd logs (pppdump-format files)
VMS's TCPIPtrace utility
DBS Etherwatch for VMS
Traffic captures from Visual Networks' Visual UpTime
CoSine L2 debug output
Output from Accellent's 5Views LAN agents
Endace Measurement Systems' ERF format
Linux Bluez Bluetooth stack "hcidump -w" traces
Network Instruments Observer version 9
Trace files for the EyeSDN USB S0

In addition, it can read gzipped versions of any of these files
automatically, if you have the zlib library available when compiling
Wireshark. Wireshark needs a modern version of zlib to be able to use
zlib to read gzipped files; version 1.1.3 is known to work.  Versions
prior to 1.0.9 are missing some functions that Wireshark needs and won't
work.  "./configure" should detect if you have the proper zlib version
available and, if you don't, should disable zlib support. You can always
use "./configure --disable-zlib" to explicitly disable zlib support.

Although Wireshark can read AIX iptrace files, the documentation on
AIX's iptrace packet-trace command is sparse.  The 'iptrace' command
starts a daemon which you must kill in order to stop the trace. Through
experimentation it appears that sending a HUP signal to that iptrace
daemon causes a graceful shutdown and a complete packet is written
to the trace file. If a partial packet is saved at the end, Wireshark
will complain when reading that file, but you will be able to read all
other packets.  If this occurs, please let the Wireshark developers know
at wireshark-dev@wireshark.org, and be sure to send us a copy of that trace
file if it's small and contains non-sensitive data.

Support for Lucent/Ascend products is limited to the debug trace output
generated by the MAX and Pipline series of products.  Wireshark can read
the output of the "wandsession" "wandisplay", "wannext", and "wdd"
commands.  For detailed information on use of these commands, please refer
the following pages:

"wandsession", "wandisplay", and "wannext" on the Pipeline series:

"wandsession", "wandisplay", and "wannext" on the MAX series:

"wdd" on the Pipeline series:

Wireshark can also read dump trace output from the Toshiba "Compact Router"
line of ISDN routers (TR-600 and TR-650). You can telnet to the router
and start a dump session with "snoop dump".

CoSine L2 debug output can also be read by Wireshark. To get the L2
debug output, get in the diags mode first and then use
"create-pkt-log-profile" and "apply-pkt-log-profile" commands under
layer-2 category. For more detail how to use these commands, you
should examine the help command by "layer-2 create ?" or "layer-2 apply ?".

To use the Lucent/Ascend, Toshiba and CoSine traces with Wireshark, you must 
capture the trace output to a file on disk.  The trace is happening inside 
the router and the router has no way of saving the trace to a file for you.
An easy way of doing this under Unix is to run "telnet <ascend> | tee <outfile>".
Or, if your system has the "script" command installed, you can save
a shell session, including telnet to a file. For example, to a file named

$ script tracefile.out
Script started on <date/time>
$ telnet router
..... do your trace, then exit from the router's telnet session.
$ exit
Script done on <date/time>

If your operating system includes IPv6 support, wireshark will attempt to
use reverse name resolution capabilities when decoding IPv6 packets.

If you want to turn off name resolution while using wireshark, start
wireshark with the "-n" option to turn off all name resolution (including
resolution of MAC addresses and TCP/UDP/SMTP port numbers to names), or
with the "-N mt" option to turn off name resolution for all
network-layer addresses (IPv4, IPv6, IPX).

You can make that the default setting by opening the Preferences dialog
box using the Preferences item in the Edit menu, selecting "Name
resolution", turning off the appropriate name resolution options,
clicking "Save", and clicking "OK".

If you would like to compile wireshark without support for IPv6 name
resolution, use the "--disable-ipv6" option with "./configure".  If you
compile wireshark without IPv6 name resolution, you will still be able to
decode IPv6 packets, but you'll only see IPv6 addresses, not host names.

Wireshark can do some basic decoding of SNMP packets; it can also use the
UCD SNMP library, version 4.2.2 or later, to do more sophisticated
decoding, by reading MIB files and using the information in those files
to display OIDs and variable binding values in a friendlier fashion. 
The configure script will automatically determine whether you have the
UCD SNMP library on your system, and will use it if it's version 4.2.2
or later.  If you have an SNMP library but _do not_ want to have
wireshark use it, you can run configure with the "--without-ucd-snmp"

If you have an earlier version of the UCD SNMP library on your system,
the configure script will stop, reporting that it can't find the
"sprint_realloc_objid()" routine; you should either upgrade to version
4.2.4 or later, as UCD SNMP 4.2.4 fixes some potential buffer overflow
problems, or should configure with "--without-ucd-snmp".

How to Report a Bug
Wireshark is still under constant development, so it is possible that you will
encounter a bug while using it. Please report bugs to wireshark-dev@wireshark.org.
Be sure you tell us:

	1) Operating System and version (the command 'uname -sr' may
	   tell you this, although on Linux systems it will probably
	   tell you only the version number of the Linux kernel, not of
	   the distribution as a whole; on Linux systems, please tell us
	   both the version number of the kernel, and which version of
	   which distribution you're running)
	2) Version of GTK+ (the command 'gtk-config --version' will tell you)
	3) Version of Wireshark (the command 'wireshark -v' will tell you,
	   unless the bug is so severe as to prevent that from working,
	   and should also tell you the versions of libraries with which
	   it was built)
	4) The command you used to invoke Wireshark, and the sequence of
	   operations you performed that caused the bug to appear

If the bug is produced by a particular trace file, please be sure to send
a trace file along with your bug description. Please don't send a trace file
greater than 1 MB when compressed. If the trace file contains sensitive
information (e.g., passwords), then please do not send it.

If Wireshark died on you with a 'segmentation violation', 'bus error',
'abort', or other error that produces a UNIX core dump file, you can
help the developers a lot if you have a debugger installed.  A stack
trace can be obtained by using your debugger ('gdb' in this example),
the wireshark binary, and the resulting core file.  Here's an example of
how to use the gdb command 'backtrace' to do so.

$ gdb wireshark core
(gdb) backtrace
..... prints the stack trace
(gdb) quit

The core dump file may be named "wireshark.core" rather than "core" on
some platforms (e.g., BSD systems).  If you got a core dump with
Tshark rather than Wireshark, use "tshark" as the first argument to
the debugger; the core dump may be named "tshark.core".
