Your system might provide a version +of libpcap that can be installed; if so, to compile tcpdump you might +need to install a "developer" version of libpcap as well as the +"run-time" version. You can also install tcpdump.org's version of +libpcap; see [this file](README.md) for the location. + +You will need a C99 compiler to build tcpdump. The build system +will abort if your compiler is not C99 compliant. If this happens, use +the generally available GNU C compiler (GCC) or Clang. + +After libpcap has been built (either install it with `make install` or +make sure both the libpcap and tcpdump source trees are in the same +directory), run `./configure` (a shell script). `configure` will +determine your system attributes and generate an appropriate `Makefile` +from `Makefile.in`. Now build tcpdump by running `make`. + +If everything builds ok, `su` and type `make install`. This will install +tcpdump and the manual entry. Any user will be able to use tcpdump to +read saved captures. Whether a user will be able to capture traffic +depends on the OS and the configuration of the system; see the +[tcpdump man page](https://www.tcpdump.org/manpages/tcpdump.1.html) +for details. DO NOT give untrusted users the ability to +capture traffic. If a user can capture traffic, he or she could use +utilities such as tcpdump to capture any traffic on your net, including +passwords. + +Note that most systems ship tcpdump, but usually an older version. +Building tcpdump from source as explained above will usually install the +binary as `/usr/local/bin/tcpdump`. If your system has other tcpdump +binaries, you might need to deinstall these or to set the PATH environment +variable if you need the `tcpdump` command to run the new binary +(`tcpdump --version` can be used to tell different versions apart). + +If your system is not one which we have tested tcpdump on, you may have +to modify the `configure` script and `Makefile.in`. Please +[send us patches](https://www.tcpdump.org/index.html#patches) +for any modifications you need to make. + +Please see [this file](README.md) for notes about tested platforms. + + +## Description of files +``` +CHANGES - description of differences between releases +CONTRIBUTING.md - guidelines for contributing +CREDITS - people that have helped tcpdump along +INSTALL.md - this file +LICENSE - the license under which tcpdump is distributed +Makefile.in - compilation rules (input to the configure script) +README.md - description of distribution +VERSION - version of this release +aclocal.m4 - autoconf macros +addrtoname.c - address to hostname routines +addrtoname.h - address to hostname definitions +addrtostr.c - address to printable string routines +addrtostr.h - address to printable string definitions +ah.h - IPSEC Authentication Header definitions +appletalk.h - AppleTalk definitions +ascii_strcasecmp.c - locale-independent case-independent string comparison + routines +atime.awk - TCP ack awk script +atm.h - ATM traffic type definitions +bpf_dump.c - BPF program printing routines, in case libpcap doesn't + have them +chdlc.h - Cisco HDLC definitions +cpack.c - functions to extract packed data +cpack.h - declarations of functions to extract packed data +config.guess - autoconf support +config.h.in - autoconf input +config.sub - autoconf support +configure - configure script (run this first) +configure.ac - configure script source +doc/README.* - some building documentation +ethertype.h - Ethernet type value definitions +extract.h - alignment definitions +gmpls.c - GMPLS definitions +gmpls.h - GMPLS declarations +install-sh - BSD style install script +interface.h - globals, prototypes and definitions +ip.h - IP definitions +ip6.h - IPv6 definitions +ipproto.c - IP protocol type value-to-name table +ipproto.h - IP protocol type value definitions +l2vpn.c - L2VPN encapsulation value-to-name table +l2vpn.h - L2VPN encapsulation definitions +lbl/os-*.h - OS-dependent defines and prototypes +llc.h - LLC definitions +machdep.c - machine dependent routines +machdep.h - machine dependent definitions +makemib - mib to header script +mib.h - mib definitions +missing/* - replacements for missing library functions +ntp.c - functions to handle ntp structs +ntp.h - declarations of functions to handle ntp structs +mkdep - construct Makefile dependency list +mpls.h - MPLS definitions +nameser.h - DNS definitions +netdissect.h - definitions and declarations for tcpdump-as-library + (under development) +nfs.h - Network File System V2 definitions +nfsfh.h - Network File System file handle definitions +nlpid.c - OSI NLPID value-to-name table +nlpid.h - OSI NLPID definitions +ospf.h - Open Shortest Path First definitions +packetdat.awk - TCP chunk summary awk script +parsenfsfh.c - Network File System file parser routines +pcap-missing.h - declarations of functions possibly missing from libpcap +ppp.h - Point to Point Protocol definitions +print.c - Top-level routines for protocol printing +print-*.c - The netdissect printers +rpc_auth.h - definitions for ONC RPC authentication +rpc_msg.h - definitions for ONC RPC messages +send-ack.awk - unidirectional tcp send/ack awk script +slcompress.h - SLIP/PPP Van Jacobson compression (RFC1144) definitions +smb.h - SMB/CIFS definitions +smbutil.c - SMB/CIFS utility routines +stime.awk - TCP send awk script +tcp.h - TCP definitions +tcpdump.1 - manual entry +tcpdump.c - main program +timeval-operations.h - timeval operations macros +udp.h - UDP definitions +util-print.c - utility routines for protocol printers +``` |
