Steps To Set up Zenmap on Ubuntu 22.04

Steps To Set up Zenmap on Ubuntu 22.04

To install Zenmap, you must log in to your server as a non-root user with sudo privileges. To do this, you can follow our guide the Initial Server Setup with Ubuntu 22.04.

Python 2.x has been completely phased out and the last thing you want is a bunch of outdated packages on your system. Luckily someone has forked nmap and updated Zenmap to Python 3. You can install from this source fairly easily:

Install Requirements on Ubuntu 22.04

First, you need to update your local package index with the command below:

sudo apt update

Then, use the following command to install the required packages:

sudo apt install build-essential checkinstall zlib1g-dev libssl-dev libcurl4-openssl-dev

Download Nmap Source Code From GitHub

First, you need to create a directory named Downloads and navigate to it with the commands below:

# mkdir Downloads
# cd Downloads

Then, use the following command to download the Nmap packages:

sudo wget https://github.com/nmap/nmap/archive/refs/heads/master.zip -O nmap.zip

When your download is completed, extract your file by using the command below:

sudo unzip nmap.zip

Then, navigate to your nmap directory:

cd nmap-master

Fix Zenmap Config File on Ubuntu 22.04

There is an error in the current Zenmap config file and if not fixed Zenmap will not be able to find your nmap binary. Open the file with your favorite text editor, here we use the vi editor:

sudo vi zenmap/share/zenmap/config/zenmap.conf

In the file, look for the below lines:

[paths]
nmap_command_path = ../nmap
ndiff_command_path = ../ndiff/ndiff

Then, change them to this:

[paths]
nmap_command_path = nmap
ndiff_command_path = ndiff

When you are done, save and close the file.

Note:

If you have already gotten everything installed but Zenmap can’t find nmap, you can do the same fix on the file in your home folder:

~/.zenmap/zenmap.conf

Compile and Install Zenmap on Ubuntu 22.04

At this point, you can easily use the commands below to install the Zenmap:

./configure

When it is completed, you will get the following output:
