Introduction
Now you can create your own tunnel to hide your IP address. The gtunnel tool creates an exe file based on an operating system like Windows/Linux, this exe file creates a connection directly to the server by using the tunneling process. This tunnel is very secure to communicate between source and destination systems.
Environment
- OS: Kali Linux 2020 64 bit or it can be your public server to hide your IP.
- Kernel version: 5.6.0
Installation Steps
- Use this command to clone the project.
- git clone https://github.com/hotnops/gtunnel
root@kali:/home/iicybersecurity# git clone https://github.com/hotnops/gtunnel Cloning into 'gtunnel'... remote: Enumerating objects: 186, done. remote: Counting objects: 100% (186/186), done. remote: Compressing objects: 100% (104/104), done. remote: Total 186 (delta 85), reused 159 (delta 63), pack-reused 0 Receiving objects: 100% (186/186), 12.62 MiB | 2.19 MiB/s, done. Resolving deltas: 100% (85/85), done.
- Use the cd command to enter into gtunnel directory.
root@kali:/home/iicybersecurity# cd gtunnel/ root@kali:/home/iicybersecurity/gtunnel#
- Next, install docker in our machine by using this command sudo apt install docker.io
root@kali:/home/iicybersecurity/gtunnel# sudo apt install docker.io Reading package lists... Done Building dependency tree Reading state information... Done The following additional packages will be installed: cgroupfs-mount libintl-perl libintl-xs-perl libmodule-find-perl libmodule-scandeps-perl libproc-processtable-perl libsort-naturally-perl needrestart runc tini Suggested packages: ==================================================================================================SNIP================================================================================================================================ Created symlink /etc/systemd/system/sockets.target.wants/docker.socket → /lib/systemd/system/docker.socket.

- After installing the docker, use this command to download the gtunnel image file using docker and start the server.

- Here, we have few help options.
- Now, use this command to configure the client configclient <OS> <server’s IP> <Port> <File name>
- configclient win 192.168.0.28 443 iics1
>>> configclient win 192.168.0.28 443 iics1 >>>
- Generated exe file will be stored in the configured directory. Use cd command to move into the configured directory and send the exe file to the client machine.
- When the client run’s the exe file tunnel will be established to the server machine.
>>> configclient win 192.168.0.28 443 iics1 >>> 2020/08/07 11:46:26 Endpoint connected: id: iics1
- Now, type “use” command to connect to the end point.
>>> use iics1 (iics1) >>>
- Now add tunnel to forward the traffic through server IP by using this command.
- addtunnel remote <listener Port> <destination IP> <destination port> <file name>
- Verify the tunnel added by using this command “listtunnels”
(iics1) >>> listtunnels Tunnel ID: iics
- Now, if we browser in our search engine, the traffic will travel from server IP. For this we can capture the traffic through Wireshark.
- In the above picture, we see the packet travelling through server IP Address.
Conclusion
We saw on how to make a secure connection between server and client for communicating with each other using tunneling process.
