$Id: README.win32 14003 2005-04-01 21:23:40Z sahlberg $ Installing Ethereal, Tethereal, and Editcap on Win32 ==================================================== These are the instructions for installing Ethereal from the installation executable that is provided on the Ethereal website at: http://www.ethereal.com/distribution/win32 and any of its mirrors. The installation package allows you to install: o Ethereal - the GUI version o Tethereal - the console, line-mode version o Editcap - a console, line-mode utility to convert capture files from one format to another. (The same functions are available in Ethereal) o Text2Pcap - a console, line-mode utility to generate a capture file from an ASCII hexdump of packets o Mergecap - a console, line-mode utility to merge two capture files into one Additionally, the installation package contains a "plugins" option, which installs some additional dissector plugins for use with Ethereal and Tethereal. All binaries in Ethereal package are now built with debugging information embedded. If you are experiencing a crash when running Ethereal or other binaries, Dr. Watson or your debugger can use the information embedded in the binary to provide useful information to the Ethereal developers that will help them pinpoint the problem. In the past, two versions of Ethereal binaries were published -- a version that could capture packets and a version which could not. The latter is useful if you're only reading files produced by another product (e.g., a sniffer, firewall, or intrustion detection system) and did not wish to install WinPcap, the library Ethereal uses to capture packets on Win32 platforms. As of WinPcap 2.1, all the WinPcap libraries have been released as DLLs. This means that Ethereal can detect the presence of WinPcap at run time, which means that only one version of the Ethereal binaries needs to be shipped. If you don't want to capture packets, just install the Ethereal package. If you do want to capture packets, install Ethereal *and* install the latest non-beta version of WinPcap, available from: http://winpcap.polito.it/ and mirrored at http://winpcap.mirror.ethereal.com/ and http://www.mirrors.wiretapped.net/security/packet-capture/winpcap/ If you already have an earlier version of WinPcap installed, you need to un-install it and install the latest version. If the older version is WinPcap 2.0 or 2.02, and you have other applications that use the older version , you will have to decide which applications to keep, since WinPcap 2.0/2.02 and later versions cannot be installed on the same system at the same time. If Ethereal is not capturing packets and you have WinPcap installed, you can test your WinPcap installation by installing WinDump (tcpdump for Windows) ported by the same folks who make WinPcap. It's at: http://windump.polito.it/ and mirrored at http://windump.mirror.ethereal.com/ and http://www.mirrors.wiretapped.net/security/packet-capture/windump/ They also make Analyzer, a GUI sniffer for Win32: http://analyzer.polito.it/ The rest of this documentation is only interesting if you want to compile Ethereal yourself. Compiling the Ethereal distribution from source =============================================== Compilers --------- MS Visual C++ Version 6 This is the common compiler used for building Ethereal on win32. MS Visual C++ Version 7 / VC.NET Currently unsupported for two reasons: -the licence agreement does NOT allow you to compile GPL code. -there are serious problems in using DLL's compiled with MS VC6. See section "Problems with MS Visual C++ Version 7 / VC.NET" below. Cygwin GCC Ethereal can entirely be built with cygwin GCC. However the built binaries will only run in a cygwin environment, so they are not standalone Win32 applications. It is however not excluded that native Win32 code can be compiled on cygwin GCC but you then have to use -mms-bitfields as a strict minimum and probably -mno-cygwin or a similar compiler flag too. See section below for instructions. Automated library download -------------------------- Before using the automated download, be sure to edit the config.nmake file to suit your needs. Especially have a look at the ETHEREAL_LIBS setting. However, the defaults should be working well for a first start. If you've installed Microsoft Visual C++ (MSVC), you can run: nmake -f makefile.nmake setup This will first check the availability of all required tools and then uses the tool wget to download each package file (together around 30MB!) from the server location at: http://anonsvn.ethereal.com/ethereal-win32-libs/trunk/packages/ and unpack it in the $ETHEREAL_LIBS directory. If you have problems downloading the files, you might be connected to the internet through a proxy/firewall. In this case see the wget documentation to configure wget accordingly. Required libraries ------------------ If the automated library download finished sucessfully, you should have all libraries on your machine at the right places. So you don't have to read this, unless you are interested which libraries are used. You'll need the development packages for GLIB, GTK+, iconv, gettext, WinPcap, Net-SNMP, and optionally ADNS, PCRE and zlib. The development packages contain header files and stub libraries to link against. PRECOMPILED VERSIONS OF ALL OF THESE PACKAGES ARE AVAILABLE AT: http://anonsvn.ethereal.com/ethereal-win32-libs/trunk/packages/ The GLIB, GTK+, iconv, gettext packages for win32 can be found at the home page for the GTK+ for Win32 project: http://www.gimp.org/~tml/gimp/win32 or the mirror http://www.iki.fi/tml/gimp/win32/ The Net-SNMP package for win32 is available at its homepage: http:// The WinPcap package is available at its homepage: http://winpcap.polito.it/ or the mirror http://www.wiretapped.net/security/packet-capture/winpcap/default.htm The optional ADNS package for win32 is available at its homepage: http://adns.jgaa.com/ The optional PCRE package (Perl Compatible Regular Expressions) for win32 is available at its homepage: http://gnuwin32.sourceforge.net/packages/pcre.htm The optional zlib package for win32 is available at its homepage: http://www.gzip.org/zlib/ By default, the build process looks for these packages in C:\ethereal-win32-libs. You can place them in a different directory, but you must update the ETHEREAL_LIBS variable in config.nmake accordingly. The following lists the packages needed to compile Ethereal and the default locations where to unpack them, when the above method isn't used. Package Default Location ------- ---------------- glib-2.2.3-20040116.zip C:\ethereal-win32-libs\glib glib-dev-2.2.3-20040116.zip C:\ethereal-win32-libs\glib gtk+-1.3.0-20030717.zip C:\ethereal-win32-libs\gtk+ gtk+-dev-1.3.0-20030115.zip C:\ethereal-win32-libs\gtk+ libiconv-1.9.1.bin.woe32.zip C:\ethereal-win32-libs\libiconv-1.9.1.bin.woe32 gettext-runtime-0.13.1.zip C:\ethereal-win32-libs\gettext-runtime-0.13.1 net-snmp-5.1.zip C:\ethereal-win32-libs wpdpack_3_0.zip C:\ethereal-win32-libs and optional: adns-1.0-win32-03.zip C:\ethereal-win32-libs pcre-4.4.zip C:\ethereal-win32-libs zlib122-dll.zip C:\ethereal-win32-libs\zlib122-dll (to use the default locations, the directories in question should be created, and each zip file should be unpacked into the corresponding directory). If you only want to change the C:\ethereal-win32-libs part, you just change the setting of ETHEREAL_LIBS in config.nmake; if you want to change subdirectories, you'll have to change the individual item for a package. (Note that some zip files create the subdirectory - those zip files just have C:\ethereal-win32-libs in the list above - so if you don't want the package to be in that subdirectory, you'd have to rename the directory.) The gettext runtime package provides intl.dll, which is needed by GLib 2.2.3. Compiling the Ethereal distribution using GTK+2 ----------------------------------------------- The more recent version 2 of the GTK+ can be used to compile Ethereal with, but is still considered beta. GTK+2 will look better in various ways, especially for WIN32 users. You can get the required libraries from: http://www.ethereal.com/distribution/win32/development/gtk2 or (like the GTK+1 libraries from the GTK+ for Win32 project): http://www.gimp.org/~tml/gimp/win32/downloads.html If you want to try a build with GTK+2.x these Extra libraries are needed Package Default Location ------- ---------------- gtk+-2.2.4-20040124.zip C:\ethereal-win32-libs\gtk2 gtk+-dev-2.2.4-20040124.zip C:\ethereal-win32-libs\gtk2 pango-1.2.5-20040124.zip C:\ethereal-win32-libs\gtk2 pango-dev-1.2.5-20040124.zip C:\ethereal-win32-libs\gtk2 atk-1.4.0.zip C:\ethereal-win32-libs\gtk2 atk-dev-1.4.0.zip C:\ethereal-win32-libs\gtk2 and optional: gtk-wimp-0.5.3-bin.zip C:\ethereal-win32-libs\gtk-wimp Be sure to set GTK2_DIR in config.nmake correct, to be able to compile. Running your freshly compiled Ethereal -------------------------------------- Make sure the glib and gtk DLL's are in your path or you use a directory where all required DLL's and the exe files reside.- i.e., that your path includes the directory (folder) or directories (folders) in which those DLLs are found - when you run Ethereal. Note the wiretap*.dll must be in your path as well and if wiretap is changed be sure to put the new one in your path. Plugins (gryphon.dll and mgcp.dll) can go in: <Ethereal installation directory>\plugins\<version> Where <version> is the version number, without brackets. For example, if you have Ethereal 0.9.8 installed in the default location, plugins will reside in C:\Program Files\Ethereal\plugins\0.9.8 Yes, the location of plugins needs to be more flexible. Instructions for MS Visual C++ ---------------------------- Modify the config.nmake file in the top directory of the Ethereal source tree to work for your local configuration; if you don't have Python, comment out the line that defines PYTHON, otherwise set it to refer to the pathname of your Python interpreter executable. You should not have to modify any other Makefile. Note that perl is needed to build the documentation, the lines in config.nmake POD2MAN=$(SH) pod2man POD2HTML=$(SH) pod2html requires Cygwin bash and perl to work. Many of the file and directory names used in the build process go past the old 8.3 naming limitations. As a result, at least on Windows NT 4.0, Windows 2000, Windows XP, and Windows .NET Server, you should use the newer "cmd.exe" command interpreter instead of the old "command.com", as the "command.com" on Windows 2000, at least, can't handle non-8.3 directory names. (It may be that the "command.com" in Windows 95, Windows 98, and Windows Me, as it's the only command interpreter in those systems, can handle those directories. If not, it may not be possible to build Ethereal from the command line on those versions of Windows.) Be sure that your command-line environment is set up to compile and link with MSVC++. When installing MSVC++, you can have your system's environment set up to always allow compiling from the command line, or you can invoke the vcvars32.bat script, which can usually be found in the "VC98\Bin" subdirectory of the directory in which Visual Studio was installed. The first time you build Ethereal, run the script "cleanbld.bat" in the top-level Ethereal source directory to make sure that the "config.h" files will be reconstructed from the "config.h.win32" files. (If, for example, you have "config.h" files left over from a Unix build, a Windows build will fail.) In the ethereal directory, type "nmake -f makefile.nmake". It will recurse into the subdirectories as appropriate. Some generated source is created by traditionally "Unix-ish" tools. If you are building from an official distribution, these files are already generated, although they were generated on a Unix-compatible system. In most cases, the generated files can be used when building on Windows, but the files listed below as being generated by Flex can be used when building on Windows only when generated by a Windows version of Flex, so you will need a Windows version of Flex to do a Windows build. Those generated files are removed by the "cleanbld.bat" script, to make sure that versions left over from a Unix build aren't used. If you are building from a modified version of an official distribution, and you modified any of the source files listed below, you will need the tool(s) that generate output from those source files. If building from a CVS image, you'll need all the tools to generate C source. The "special" files and their requisite tools are: Source Output Tool ------ ------ ---- config.h.win32 config.h sed epan/config.h.win32 epan/config.h sed image/ethereal.rc.in image/ethereal.rc sed image/tethereal.rc.in image/tethereal.rc sed image/editcap.rc.in image/editcap.rc sed image/mergecap.rc.in image/mergecap.rc sed image/text2pcap.rc.in image/text2pcap.rc sed wiretap/config.h.win32 wiretap/config.h sed epan/dfilter/dfilter-scanner.l epan/dfilter/*.c Flex text2pcap-scanner.l *.c Flex wiretap/ascend-scanner.l *.c Flex wiretap/ascend-grammar.y *.c,*.h Bison/Yacc ncp2222.py packet-ncp2222.c Python make-reg-dotc, packet*.c register.c Bash + grep + sed or make-reg-dotc.py, packet*.c register.c Python make-tapreg-dotc, tap-*.c tethereal-tap-register.c Bash + grep + sed make-tapreg-dotc, tap files gtk/ethereal-tap-register.c in the gtk subdirectory Bash + grep + sed The Makefile.nmake supplied with the Ethereal distribution will, if PYTHON is defined in config.nmake, attempt to make register.c with Python, since it is much much much faster than the shell version. The reason it is faster is because the shell version launches multiple processes (grep, sed) for each source file, multiple times. The Python script is one process. This matters a lot on Win32. If you have a Unix system handy, you can first build on Unix to create most of the source files that these tools make, then run the build on Windows. That will avoid the need for these tools on your Windows computer. This won't work for the files in the "image" directory, however, as those aren't built on Unix - they're only for Windows builds. It also won't work for the "config.h" files; whilst those are built for Unix, they're specific to the platform on which you're building, and the "config.h" files constructed for a Unix build will not work with a Windows build. In addition, it won't work for the files generated by Flex, as, for a Windows build, those have to be generated by a Windows version of Flex. Most of those tools are available for Win32 systems as part of the Cygwin package: http://www.cygwin.com/ After installing them, you will probably have to modify the config.nmake file to specify where the Cygwin binaries are installed. Note that installing cygwin with the "Default Text File Type" set to DOS may break the compilation because all the required tools may not be found. Set this parameter to UNIX instead. Python for Win32 is available from: http://www.python.org/ Build an (NSIS based) installer ------------------------------- If you want to build your own installer, you need to get NSIS from: http://nsis.sourceforge.net/home/ After installing it, you will probably have to modify the config.nmake file to specify where the NSIS binaries are installed and wether to use the modern UI or not. You will need NSIS version 2 or higher, to build an installer with the modern user interface, and for a much smaller installer (using the lzma compression). In the ethereal directory, type "nmake -f makefile.nmake packaging" to build the installer. Please be patient while the compression is done, it will take some time even on fast machines. You will hopefully now see something like ethereal-setup-0.10.2.exe in the dir packaging/nsis. Installing GTK-Wimp ------------------- GTK-Wimp can be used to get a native Look-and-Feel on WinXP machines, especially with the new "coloured" WinXP theme. It will only take effect together with the GTK2 version of Ethereal. No changes to the Ethereal sources are needed, GTK-Wimp simply changes the way GTK2 displays the widgets (by changing the GTK2 default theme). GTK-Wimp might already be installed. In this case, the files mentioned below are already existing at the appropriate places. If GTK-Wimp isn't installed, you can install it yourself: 1. Go to http://gtk-wimp.sourceforge.net/ 2. Download the ZIP archive containing the library and the theme 3. Locate the installation directory of Ethereal (C:\Program Files\Ethereal) 4. Create a subdirectory 'share\themes\Default\gtk-2.0' 5. Drop the file 'gtkrc' in 'share\themes\Default\gtk-2.0' 6. Create a subdirectory named 'lib\gtk-2.0\2.2.0\engines' 7. Drop the 'libwimp.dll' library in 'lib\gtk-2.0\2.2.0\engines' When you're finished, you should have: C:\Program Files\Ethereal\lib\gtk-2.0\2.2.0\engines\libwimp.dll C:\Program Files\Ethereal\share\themes\Default\gtk-2.0\gtkrc After (re-)starting Ethereal, you should now see it's widgets in the modern WinXP style on your screen. Problems with MS Visual C++ Version 7 / VC.NET ---------------------------------------------- Beside licensing problems with these compilers, there are known problems with DLL's. If Ethereal is compiled with MSVC Version 7, there are conflicts in the MSVCRT DLL's, The MSVCRT.DLL includes the standard ANSI-C functions like fopen, malloc, etc.. MSVCRT.DLL is shipped with the MSVC 6 compiler versions, and dynamically linked to prebuild DLL's like the one's for gtk, glib and such. The MSVC 7 compiler now uses and ships MSVCRT71.DLL with it, which is incompatible with MSVCRT.DLL. So when using the MSVC 7 compiler, some parts of the Ethereal code uses MSVCRT71.DLL, and some others (indirectly from e.g. the gtk DLL) will use MSVCRT.DLL. This will result in incorrect file handles and such. The same problem seems to apply on all MSVC compilers after version 6, like the "Microsoft Visual C++ Toolkit 2003". Instructions for Cygwin ----------------------- It is possible to build Ethereal under Cygwin using their version of XFree86. References: - http://www.ethereal.com/lists/ethereal-dev/200205/msg00107.html - http://www.ethereal.com/lists/ethereal-dev/200302/msg00026.html To get it running, execute the following steps: 1. Install the required cygwin packages (compiler, scripting, X, zlib) with the CygWin setup.exe tool (http://www.cygwin.com/). You need the base Xfree86 support plus the X headers package in order to be able to compile the gtk+ package. 2. Download glib-1.2.10 and gtk+-1.2.10 from a mirror of www.gnome.org. 3. Retrieve the patches for glib-1.2.10 and gtk+-1.2.10 from http://homepage.ntlworld.com/steven.obrien2/ + glib-1.2.10 http://homepage.ntlworld.com/steven.obrien2/ (URL cont'd on next line) /libs/patches/glib-1.2.10-cygwin.patch + gtk+-1.2.10 http://homepage.ntlworld.com/steven.obrien2/ (URL cont'd on next line) /libs/patches/gtk+-1.2.10-cygwin.patch 4. Compile and install both packages after patching (see instructions at the bottom of http://homepage.ntlworld.com/steven.obrien2/): Set the path: $ PATH=/opt/gnome/bin:/usr/X11R6/bin:$PATH For glib-1.2.10: $ cd glib-1.2.10 $ patch -p1 < /path/to/glib-1.2.10-cygwin.patch $ CFLAGS=-O2 ./configure --prefix=/opt/gnome --with-threads=posix $ make $ make check $ make install For gtk+-1.2.10: $ cd gtk+-1.2.10 $ patch -p1 < /path/to/gtk+-1.2.10-cygwin.patch $ CFLAGS=-O2 ./configure --prefix=/opt/gnome $ make $ make check $ make install 5. Patch Makefile.am in <ethereal-src>/gtk/Makefile.am by removing "ethclist.c" from the dependencies. This patch is required since the private GTK+ clist widget (was required for earlier versions of GTK+ but prevents Ethereal from running with cygwin). 6. Configure and make Ethereal: Set the path (if this has not yet been done earlier) $ PATH=/opt/gnome/bin:$PATH $ ./autogen.sh $ ./configure --config-cache --without-pcap $ make 7. Start X $ sh /usr/X11R6/bin/startxwin.sh Or you can start it from C:\cygwin\usr\X11R6\bin\startxwin.bat 8. Run ethereal (add /opt/gnome/bin to $PATH if this is not yet done) $ <ethereal-src>/ethereal And voila! Behold the mighty sniffer in all its glory! Note that the plugin dissectors must be installed (make install) if you want to use them. Note also that running "make install" produces lots of output to the console; this is normal. Note: Compiling Ethereal under cygwin takes a lot of time, because the generation of 'register.c' takes ages. If you only edit one dissector and you know what you're doing, it is acceptable to uncomment the generation of the file 'register.c' in Makefile. Look for the 'register.c' target: register.c: $(DISSECTOR_SRC) $(srcdir)/make-reg-dotc @echo Making register.c # @$(srcdir)/make-reg-dotc register.c $(srcdir) $(DISSECTOR_SRC) @echo Skipping generation of register.c Of course, you need to generate the 'register.c' file at least once. Note: You can also capture packets on a cygwin built Ethereal. You then have to unpack the WinPCap development package, install the files in lib/ and include/ in say /usr/lib and /usr/include (they must be in the search path of the compiler and linker, otherwise you have to specify the configure option --with-pcap=/location/to/pcap so the packet capture functionality can be used. In order to run Ethereal, you have to add the .dll files in a directory in the PATH (e.g., /bin). Should you want packet capturing enabled in the cygwin build, then you have to remove --without-pcap from step 6.
