- * Description:

-libpcap for DOS
----------------
-
-This file contains some notes on building and using libpcap for MS-DOS.
-Look in `README' and `pcap.man' for usage and details. These targets are
-supported:
-
- - Borland C 4.0+ small or large model.
- - Metaware HighC 3.1+ with PharLap DOS-extender
- - GNU C 2.7+ with djgpp 2.01+ DOS extender
- - Watcom C 11.x with DOS4GW extender
-
-Note: the files in the libpcap.zip contains short truncated filenames.
- So for djgpp to work with these, disable the use of long file names by
- setting "LFN=n" in the environment. On the other hand, if you get libpcap
- from GitHub or the official libpcap.tar.gz, some filenames are beyond 8+3.
- In this case set "LFN=y".
-
-Files specific to DOS are pcap-dos.[ch] and the assembly and C files in
-the MSDOS sub-directory. Remember to built the libpcap library from the top
-install directory. And not from the MSDOS sub-directory.
-
-Note for djgpp users:
- If you got the libpcap from the official site www.tcpdump, then that
- distribution does NOT contain any sources for building 32-bit drivers.
- Instead get the full version at
- https://www.watt-32.net/pcap/libpcap.zip
-
- and set "USE_32BIT_DRIVERS = 1" in msdos\common.dj.
-
-
-
-Requirements
-------------
-
-DOS-libpcap currently only works reliably with a real-mode Ethernet packet-
-driver. This driver must be installed prior to using any program (e.g.
-tcpdump) compiled with libpcap. Work is underway to implement protected-
-mode drivers for 32-bit targets (djgpp only). The 3Com 3c509 driver is
-working almost perfectly. Due to lack of LAN-cards, I've not had the
-opportunity to test other drivers. These 32-bit drivers are modified
-Linux drivers.
-
-
-Required packages
------------------
-
-The following packages and tools must be present for all targets.
-
-1. Watt-32 tcp/ip library. This library is *not* used to send or
- receive network data. It's mostly used to access the 'hosts'
- file and other <netdb.h> features. Get 'watt32s*.zip' at:
-
- https://www.watt-32.net
-
-2. Exception handler and disassembler library (libexc.a) is needed if
- "USE_EXCEPT = 1" in common.dj. Available at:
-
- https://www.watt-32.net/misc/exc_dx07.zip
-
-3. Flex & Bison is used to generate parser for the filter handler
- pcap_compile:
- ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/flx254b.zip
- ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/bsn241b.zip
-
-4. NASM assembler v 0.98 or later is required when building djgpp and
- Watcom targets:
- https://www.nasm.us/
-
-5. sed (Stream Editor) is required for doing `make depend'.
- It's available at:
- ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/sed422b.zip
-
- A touch tool to update the time-stamp of a file. E.g.:
- ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/grep29b.zip
-
-6. For djgpp rm.exe and cp.exe are required. These should already be
- part of your djgpp installation. Also required (experimental at the
- time) for djgpp is DLX 2.91 or later. This tool is for the generation
- of dynamically loadable modules.
-
-
-Compiling libpcap
------------------
-
-Follow these steps in building libpcap:
-
-1. Make sure you've installed Watt-32 properly (see it's `INSTALL' file).
- During that installation a environment variable `WATT_ROOT' is set.
- This variable is used for building libpcap also (`WATT_INC' is
- deducted from `WATT_ROOT'). djgpp users should also define environment
- variables `C_INCLUDE_PATH' and `LIBRARY_PATH' to point to the include
- directory and library directory respectively. E.g. put this in your
- AUTOEXEC.BAT:
- set C_INCLUDE_PATH=c:/net/watt/inc
- set LIBRARY_PATH=c:/net/watt/lib
-
-2. Revise the msdos/common.dj file for your djgpp/gcc installation;
- - change the value of `GCCLIB' to match location of libgcc.a.
- - set `USE_32BIT_DRIVERS = 1' to build 32-bit driver objects.
-
-
-3. Build pcap by using appropriate makefile. For djgpp, use:
- `make -f msdos/makefile.dj' (i.e. GNU `make')
-
- For a Watcom target say:
- `wmake -f msdos\makefile.wc'
-
- For a Borland target say:
- `maker -f msdos\Makefile pcap_bc.lib' (Borland's `maker.exe')
-
- And for a HighC/Pharlap target say:
- `maker -f msdos\Makefile pcap_hc.lib' (Borland's `maker.exe')
-
- You might like to change some `CFLAGS' -- only `DEBUG' define currently
- have any effect. It shows a rotating "fan" in upper right corner of
- screen. Remove `DEBUG' if you don't like it. You could add
- `-fomit-frame-pointer' to `CFLAGS' to speed up the generated code.
- But note, this makes debugging and crash-traceback difficult. Only
- add it if you're fully confident your application is 100% stable.
-
- Note: Code in `USE_NDIS2' does not work at the moment.
-
-4. The resulting library is put in current directory. There's some
- test-program for `libpcap': `filtertest.exe', `findalldevstest.exe',
- `nonblocktest.exe' and `opentest.exe'.
-
- But linking the library with `tcpdump' is the ultimate test. DOS/djgpp
- should now hopefully be a supported target. Get the sources at:
- https://www.tcpdump.org/
- or
- https://github.com/the-tcpdump-group/tcpdump/
-
- (click on the 'Download ZIP' on the right side of that page.)
-
-
-Extensions to libpcap
----------------------
-
-I've included some extra functions to DOS-libpcap:
-
- `pcap_config_hook (const char *keyword, const char *value)' :
-
- Allows an application to set values of internal libpcap variables.
- `keyword' and an associated `value' should be present in the `debug_tab[]'
- array in pcap-dos.c (currently only used to set debug-levels and parameters
- for the 32-bit network drivers.) Thus an application using DOS-libpcap can
- override the default value during it's configure process (see tcpdump's
- msdos/config.c file for an extended example).
-
- `pcap_set_wait (pcap_t *, void (*)(void), int)' :
-
- Only effective when reading offline traffic from dump-files.
- Function `pcap_offline_read()' will wait (and optionally yield)
- before printing next packet. This will simulate the pace the packets
- where actually recorded.
-
-
-
-Happy sniffing !
