Stop DHCP services on Linux - Ubuntu

Question

How do I stop DHCP services on a particular ethernet port in Linux ? I was trying to take full control of an ethernet port of my computer to inject packets into the device plugged into it without being interfered by DHCP request traffic.

Solution

As far as an interface getting an IP via DHCP, that's controlled by /etc/network/interfaces - change any dhcp you find in the appropriate stanzas to static.

Is your intention to disable DHCP and configure a static IP address on an eth interface? Ubuntu Network Configuration Guide

This is what I am trying to do. stackoverflow.com/questions/18621261/masquerading-a-webserve‌​r I want to setup a connection with my network device and respond to the GET request it is sending with my local webserver Perl script. I thought I should disable all system service before I can inject http traffic into the port.

Probably want to disable NetworkManager if it's running, service stop NetworkManager or similar. Then you may want to run lsof -i or netstat to see what else is listening, and stop programs or disable services accordingly if you want absolutely no other traffic on that interface.
