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.

1Is your intention to disable DHCP and configure a static IP address on an eth interface? Ubuntu Network Configuration Guide– one.timeCommented Sep 6, 2013 at 3:59

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.

This is what I am trying to do. stackoverflow.com/questions/18621261/masquerading-a-webserver 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.– JeanCommented Sep 6, 2013 at 14:50

1Probably want to disable NetworkManager if it's running,
service stop NetworkManageror similar. Then you may want to runlsof -iornetstatto see what else is listening, and stop programs or disable services accordingly if you want absolutely no other traffic on that interface. Commented Sep 6, 2013 at 16:31
