6.10.15 Assignment: Networking Applications
Overview
This assignment is part of the Networking With Xinu track for professors that are teaching with Xinu and it is intended
to be completed in groups of two or three.
Preparation
A new tar-ball is provided with a solution to the previous assignment. If your solution is similar to the one presented,
you may choose to continue on with it; but it is suggested that you untar the new project files in a fresh working
directory:
tar xvzf
Shell Commands
We have a few more protocols within our networking portion of Embedded Xinu. In this assignment we will add shell
commands to create useful interaction with those protocols. We will be adding two shell commands: tcp-con and
ftp-receive.
Upon completion of the assignment the students’ implementation should have all the required shell commands properly
implemented and well tested.
Required Assignment Parts
Shell Command Descriptions
• tcp-con establishes a tcp connection with the provided IP address
• ftp-receive uses a TCP/IP connection to transfer acquire a file from a provided remote location
Shell Command Options
• tcp-con
– options for: determine whether the connection establishment is active or passive
– add help option that prints usage
• ftp-receive
– options for: determine whether to use passive or active connection establishment for file transfer
– add help option that prints usage
Student Outcomes
Upon completion of this assignment students should understand how to implement various shell commands that interact with the underlying network interface. Implementing the shell commands should give the student a better grasp of
how the various protocols actually work.
