Implementing Networking

Getting a Static IP Address

Getting a static IP at Wellesley is fairly simple for those on campus, and any users planning on connecting their Linux boxes to the Wellesley network as a server need to get a static IP address. Any servers set up without a static IP address will find their addresses changing each time the computer is restarted, which will make web-serving and other services nigh-impossible to set up.

Getting a static IP requires the user to know what dorm the computer will be in, the Ethernet address of the Ethernet card in the computer, and the name intended for the computer.

The first step is to find out what your Ethernet address is.

The second step is to find out what Dormitory or building the computer is to be housed in. (Munger, for example.)

The third step is to name the computer. Each computer on the Wellesley network needs to have a unique name. (Ariel is unique. So is Sallie, and Alice.) To check whether or not a name is available, log in to Sallie and at the dollar prompt, type:

and replace VMSSUCKS with the prospective name for the computer. It should then spout back:


*** LOCALHOST can't find VMSSUCKS: Non-existent host/domain

If it returns this, the name is unique. If it returns anything else, the computer needs to be named something different.

Once the name, Ethernet address, and location are certain, email Tim Cantin (, and give him this information, and he will get back to you with a static IP address for that computer.

Networking Setup During Install

To connect a Linux machine to the Wellesley network, there are several steps and pieces necessary. First, the machine needs to have an installed and recognized 10baseT Ethernet card, and the user needs to have followed the instructions for getting a static IP. Then, during the installation process, there will be two screens where this data needs to be input.

The first screen is titled "Configure TCP/IP" and asks for:

The second screen is titled "Configure Network" and asks for:

(Note: this data is subject to change without being updated here, and the wise user will check with the network people about whether it is correct.)

Then, once the computer is started up, plug a standard RJ45 Ethernet cord into the drop in the wall and into the computer and the Linux box is now connected to the Ethernet, and from there, to the Internet.
