Socat is a command-line based utility that establishes two bidirectional byte streams and transfers data between them.

Objective: Learn socat tool by doing the following activities:

  1. Use socat to listen on TCP port 4000 of the localhost. Open a new tab and use socat to connect to the listening instance.

  2. Use socat to listen on UDP port 4000 of the localhost. Open a new tab and use socat to connect to the listening instance.

  3. Use socat to listen on TCP port 4000 of the localhost. Open a new tab and use socat to connect to the listening instance. Protect the communication using SSL/TLS.

  4. Use socat to listen on port 4000 of the localhost and provide bash access to any session connecting to it. Open a new tab and use socat to connect to the listening instance. 

  5. Use socat to listen on a UNIX socket. Open a new tab and use socat to connect to the listening instance.

  6. SSH service is running on one of the remote target machines. Use socat to create a tunnel from local port 8000 to this remote SSH service. The SSH credentials are given below:

    • Username: student

    • Password: student 


Instructions:

  • This lab is dedicated to you! No other users are on this network :) 
  • Your machine has an interface with IP address 192.X.Y.Z. Run "ip addr" to know the values of X and Y.
  • The target server should be located at the IP address 192.X.Y.3. 
  • Do not attack the gateway located at IP address 192.X.Y.1 


The following activities are strictly prohibited on this website unless otherwise explicitly stated as allowed in the mission statement:

  • Using automated scanners
  • Using brute force attacks
  • Denial of Service attacks
  • Attacking other student machines in challenges where you might achieve a shell on the vulnerable system
  • Attacking the lab infrastructure

Users violating the above will be either temporarily or permanently banned from the website. 

If you are unsure about an activity, then please contact support to confirm that it is allowed on our website.

Technical Support for this Lab:

There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!

We currently provide technical support limited to:

  • Giving hints for a lab exercise
  • In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
  • A lab exercise fails to load or has errors in it

If you need technical support, please email  attackdefense@pentesteracademy.com  clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
