   1 # tcpdump installation notes
   2 If you have not built libpcap, and your system does not have libpcap
   3 installed, install libpcap first.  Your system might provide a version
   4 of libpcap that can be installed; if so, to compile tcpdump you might
   5 need to install a "developer" version of libpcap as well as the
   6 "run-time" version.  You can also install tcpdump.org's version of
   7 libpcap; see [this file](README.md) for the location.
   8
   9 You will need a C99 compiler to build tcpdump.  The build system
  10 will abort if your compiler is not C99 compliant.  If this happens, use
  11 the generally available GNU C compiler (GCC) or Clang.
  12
  13 After libpcap has been built (either install it with `make install` or
  14 make sure both the libpcap and tcpdump source trees are in the same
  15 directory), run `./configure` (a shell script). `configure` will
  16 determine your system attributes and generate an appropriate `Makefile`
  17 from `Makefile.in`.  Now build tcpdump by running `make`.
  18
  19 If everything builds ok, `su` and type `make install`.  This will install
  20 tcpdump and the manual entry.  Any user will be able to use tcpdump to
  21 read saved captures.  Whether a user will be able to capture traffic
  22 depends on the OS and the configuration of the system; see the
  23 [tcpdump man page](https://www.tcpdump.org/manpages/tcpdump.1.html)
  24 for details.  DO NOT give untrusted users the ability to
  25 capture traffic.  If a user can capture traffic, he or she could use
  26 utilities such as tcpdump to capture any traffic on your net, including
  27 passwords.
  28
  29 Note that most systems ship tcpdump, but usually an older version.
  30 Building tcpdump from source as explained above will usually install the
  31 binary as `/usr/local/bin/tcpdump`.  If your system has other tcpdump
  32 binaries, you might need to deinstall these or to set the PATH environment
  33 variable if you need the `tcpdump` command to run the new binary
  34 (`tcpdump --version` can be used to tell different versions apart).
  35
  36 If your system is not one which we have tested tcpdump on, you may have
  37 to modify the `configure` script and `Makefile.in`. Please
  38 [send us patches](https://www.tcpdump.org/index.html#patches)
  39 for any modifications you need to make.

  41 Please see [this file](README.md) for notes about tested platforms.
