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 trucated filenames.
So for djgpp to work with these, disable the use of long file names by
setting "LFN=n" in the environment.
Files specific to DOS are pcap-dos.[ch] and the assembly and C files in
the MSDOS sub-directory. Remember to built lipcap libraries from the top
install directory. And not from the MSDOS sub-directory.
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
opporunity 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:
http://www.bgnett.no/~giva/
2. Exception handler and disassember library (libexc.a) is needed if
"USE_EXCEPT = 1" in common.dj. Available at:
http://www.bgnett.no/~giva/misc/exc_dx07.zip
3. Flex & Bison is used to generate parser for the filter handler
pcap_compile:
ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/flx254b.zip
ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/bsn128b.zip
4. NASM assembler v 0.98 or later is required when building djgpp and
Watcom targets:
ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2tk/nasm098p.zip
5. sed (Stream Editor) is required for doing `make depend'.
It's available at
ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/sed*.zip
A touch tool to update the time-stamp of a file. E.g.
ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/grep*.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 libraries are put in current directory. There's no
test-program for `libpcap'. Linking the library with `tcpdump' is
the ultimate test anyway.
Extensions to libpcap
---------------------
I've included some extra functions to DOS-libpcap:
`pcap_config_hook (const char *name, const char *value)'
Allows an application to set values of internal libpcap variables.
`name' is typically a left-side keyword with an associated `value'
that is called from application's configure process (see tcpdump's
config.c file). libpcap keeps a set of tables that are searched for
a name/value match. Currently only used to set debug-levels and
parameters for the 32-bit network drivers.
`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.
`pcap_verbose (int mode)' :
Sets the internal verbosity mode. Currently only effective while
capturing packets to file (the `-w' option in tcpdump). `pcap_dump()'
will print to `stderr' number of packets dumped.
Happy sniffing !
