Introduction to Nmap

Nmap is a utility for network exploration and security auditing. It supports ping scanning, port scanning and TCP/IP fingerprinting.

[Note]

Note

Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Nmap Dependencies

Required

build-1.2.2.post1

Recommended

[Note]

Note

If the PyGObject3 module is not installed, you'd have to skip the command making the build system use the LFS Setuptools installation and then an Internet connection would be needed. The other packages are recommended because if they're not installed, the build process will compile and link against its own (often older) version.

liblinear-249, libpcap-1.10.5, libssh2-1.11.1, Lua-5.4.8, pcre2-10.45, and PyGObject-3.52.3

Optional

libdnet

Installation of Nmap

Make the build system use the Setuptools Python module from LFS instead of downloading a copy from the Internet, and install the Python wheels already created when running the make instead of rebuilding them again on make install: 

sed -ri Makefile.in \
    -e 's#-m build#& --no-isolation#'  \
    -e '/pip install/s#(ZENMAP|NDIFF)DIR\)/#&dist/*.whl#'

Install Nmap by running the following commands: 

./configure --prefix=/usr &&
make

If you wish to run the test suite, run the following command: 

sed -e '/import imp/d'                \
    -e 's/^ndiff = .*$/import ndiff/' \
    -i ndiff/ndifftest.py

Tests need a graphical session and to be run as the root user. To test the results, issue: 

make check

Now, as the root user: 

make install
