![]() ![]() The version in the Nmap tree is heavily modified (particularly the Windows code), so the default is to use that included version. Libdnet is an excellent networking library that Nmap uses for sending raw ethernet frames. In that case, specify -with-libpcre=included. In some cases, you may wish to use the PCRE libraries included with Nmap in preference to those already on your system. Nmap then expects the library files to be in /lib and the include files to be in /include. In that case you can tell Nmap where it can be found by specifying the option -with-libpcre= to configure. If your PCRE library is not in your compiler's standard search path, Nmap probably will not find it. Nmap normally looks for a copy on your system, and then falls back to its own copy if that fails. PCRE is a Perl-compatible regular expression library available from. Nmap will always use the version of Libpcap included in its tarball if you specify -with-libpcap=included. Nmap then expects the Libpcap library to be in /lib/libpcap.a and the include files to be in /include. If you wish to force Nmap to link with your own Libpcap, pass the option -with-libpcap= to configure. Otherwise Nmap includes its own recent copy of Libpcap (with some local modifications described in libpcap/NMAP_MODIFICATIONS in the Nmap source directory). Nmap normally looks for an existing copy of Libpcap on your system and uses that if the version number and platform is appropriate. Nmap uses the Libpcap library for capturing raw IP packets. On Red Hat–based systems, install openssl-devel. On Debian-based systems, install the libssl-dev package. ![]() Without these developer packages, Nmap will not have OpenSSL support. Some distributions ship with user OpenSSL libraries that allow running programs, but not the developer files needed to compile them. Specify -without-openssl to disable SSL entirely. Nmap then looks in /libs for the OpenSSL libraries themselves and /include for the necessary header files. If they are in a location your compiler does not search for by default, but you still want them to be used, specify -with-openssl=. Normally the Nmap build system looks for these libraries on your system and include this capability if they are found. The version detection system and Nmap Scripting Engine are able to probe SSL-encrypted services using the free OpenSSL libraries. Normally the build system checks your system for requirements such as the Python scripting language and then installs Zenmap if they are all available. This option prevents the Zenmap graphical frontend from being installed. Nmap creates subdirectories like /home/fyodor/man/man1 in the install stage if they do not already exist.
