DNS2TCPC IN KALI LINUX



WHAT IS DNS2TCPC?

DNS2TCP is a tool that encapsulates TCP sessions within the DNS protocol. On the server side, we configure the tool to listen on UDP port 53, as per the DNS standard, we also specify our domain, "example.com", and the resources.
DNS2TCP is a network tool that relays TCP connections through DNS traffic. It's made up of two parts: a client tool and a server tool. 

dns2tcpc is available on kali Linux. the installation command is: 
sudo apt install dns2tcp [4]

DNS2TCP HAS THE FOLLOWING FEATURES:

Encapsulation: Encapsulates TCP sessions within the DNS protocol. This generates smaller packets than IP-over-DNS, improving throughput. 
No root privileges: The client does not need root privileges. 
Simple identification mechanism: DNS2TCP has a simple identification mechanism but no encryption. 

How it works: DNS2TCP relays TCP connections over DNS. The client acts as a relay for a specific resource, forwarding traffic from the local machine to the remote server via DNS TXT records.

Benefits: DNS2TCP generates smaller packets than IP-over-DNS, improving throughput. 
Tools included: dns2tcpd, dns2tcpc, dns2tcpdrc, and .dns2tcprc. 
Known bugs: DNS desynchronization and dns2tcpd server not supported on Windows. 

CONCLUSION:
dns2tcpc is using dns,  to archive the goal we need to create a NS record for a new subdomain pointing to the address of our server.
