echossembly

echossembly is a simple POC exploratory program that experiments with TCP and Assembly. The project is written using NASM Assembly and is oriented towards x64 bit Linux Architectures

#Prerequisites To use the program, you will need gcc and nasm installed. You can install them on Ubuntu/Debian with the following commands

sudo apt-get install build-essentials
sudo apt-get install nasm

Setup

Simply execute the Makefile to build the project. Run the following:

• make all - Builds both the echo server and client
• make clean - Cleans up all build components for the server and client

Startup the server by executing the following command ./echo_server.out By default the echo_server listens on port 8000

Startup the client and follow the on screen prompts by executing the following command ./tcp_clnt.out 127.0.0.1 8000

Note that also telnet works on the echo server. You can use telnet the same by running

telent 127.0.0.1 8000
