How To Fix xprobe2: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu xprobe2 is provided by xprobe package.

xprobe is:

Xprobe2 allows you to determine what operating system is running on a remote host. It sends several packets to a host and analyses the returned answers.

Xprobe2’s functionality is comparable to the OS fingerprinting feature in nmap (written by a different Fyodor):

  • Outputs its level of confidence about the OS on the remote host.
  • Remains usable even if intermediate systems (routers, firewalls) make slight modifications to the packets.
  • Can list the type of intermediate device (e.g. “Linux IP masquerading”).
  • Modular architecture allows new fingerprinting tests and new OS signatures to be added.

To fix this problem, we can install more using the command below.

sudo apt-get -y install xprobe

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install xprobe.

sudo apt -y install xprobe
