Change Ubuntu Server from DHCP to a Static IP Address

If the Ubuntu Server installer has set your server to use DHCP, you will want to change it to a static IP address so that people can actually use it.

Changing this setting without a GUI will require some text editing, but that’s classic linux, right?

Let’s open up the /etc/network/interfaces file. I’m going to use vi, but you can choose a different editor

sudo vi /etc/network/interfaces

For the primary interface, which is usually eth0, you will see these lines:

auto eth0
iface eth0 inet dhcp

As you can see, it’s using DHCP right now. We are going to change dhcp to static, and then there are a number of options that should be added below it. Obviously you’d customize this to your network.

auto eth0
iface eth0 inet static

Now we’ll need to add in the DNS settings by editing the resolv.conf file:

sudo vi /etc/resolv.conf

On the line ‘name server’ replace the x with the IP of your name server. (You can do ifconfig /all to find out what they are)

You need to also remove the dhcp client for this to stick (thanks to Peter for noticing). You might need to remove dhcp-client3 instead.

sudo apt-get remove dhcp-client

Now we’ll just need to restart the networking components:

sudo /etc/init.d/networking restart

Ping If you get a response, name resolution is working(unless of course if google is in your hosts file).

Really pretty simple.

Mandare Link ED2k verso un amule su un altro computer.


Make sure aMule is installed with the aMuleCMD option checked.

We need a batch script to handle the ed2k links from the browser, and we need to add some keys to the registry to make the browser recognize the ed2k links.

Create a file named ed2k_remote.bat containing the following code:

@echo off
set link=%1
for /f "useback tokens=*" %%a in ('%link%') do set link=%%~a
"c:\Program Files\aMule\amulecmd.exe" /h server /P pass /c "add %link%"

Don't forget to replace server and pass with your data and save the file in your aMule directory C:\Program Files\aMule.

Create a file named ed2k_remote.reg containing the following code:


@="URL: ed2k Protocol"
"URL Protocol"=""

@="C:\\Program Files\\aMule\\amulegui.exe"



@="\"C:\\Program Files\\aMule\\ed2k_remote.bat\" \"%1\""

Save the file and run it (double click) to add these keys to the registry.

Internet Explorer

You should be OK with just the changes to the registry and the batch script in your aMule directory.


The first time you click an ed2k link in Firefox you will get the following dialog:

Tick the Remember box and click OK.


Open the preferences window and click the Programs tab

Click the Add... button

Make Opera aware of the ed2k link protocol with these settings:
