FAQ: Network

Locating an available network port (aka cable ID)

SODA HALL

The ports are located in rectangular floorboxes; there are generally at least a couple in each room. Each floorbox has a pair of phone jacks on the left, power in the middle, and RJ-45 Ethernet ports on the right. The ports are numbered with Cable ID numbers ending in B or C (the jacks with Cable IDs ending in ‘A’ are phone jacks). An example of a Cable ID in Soda Hall is ‘3A-075-B’. (Note: In the past, Soda Hall Cable IDs were represented without hyphens (e.g. ‘3A075B’). As of March 2003 this usage has been discontinued in favor of the hyphenated version, which corresponds to the actual labels that you will see in Soda Hall offices.)

CORY HALL

The ports are located in white boxes, generally mounted on the walls. Each box may have 1, 2, 4, 8 or more ports. Each port is labeled on the front of the box. The Cable IDs in Cory identify the endpoints of the cable – the first number will be the wiring closet and is in general the same on each floor. The second number is the room where the port is located. The third number is a unique number for each port in that room. An example of a Cable ID in Cory Hall is ‘315-395-001’.

SUTARDJA DAI HALL

In offices, network ports are built into the walls, 18 inches above the floor. In open spaces, network ports are built into the baseboard of the cubicle walls. In general, each location has one BLUE data port and one WHITE phone port. Like in Cory, the printed numbers identify the endpoints of the cable. The first number is the wiring closet, the second is the room where the port is located, and the third is a unique identifier in the room. In Sutardja Dai, which follows the current campus labeling standard, an additional suffix identifies the type of cable; “D” for data cables, or “V” for voice cables. An example of a Cable ID in Sutardja Dai Hall is ‘671-630-003-D’.

Finding IP address and MAC address

WINDOWS

Click on Start → Run.
Type command in the Run dialog box.
Type ipconfig /all and press Enter. You should see output that includes the “Physical Address” for your active network adapter — this is your MAC address.

Linux/Unix Systems

To find the MAC address on a Sun OS, Solaris, Linux, FreeBSD, or NetBSD machine; use the ifconfig -a command (as root) and look at the output for the relevant interface.

For HP-UX machines, use the lanscan command.

Macintosh

The MAC address can accessed from the menu bar and through System Preferences.

Click on the apple on the menu bar and select “About this Mac.” Click on the “System Report” button, then select “Wifi” or “Ethernet” underneath the “Network” tab. The MAC address will be listed on the right.

To access from System Preferences, select “Network” from System Preferences” then click on “Advanced”. Select the “Hardware” option and the MAC address will be listed below.

Who is my Research Support Officer?

A Research Support Officer (or RSO) oversees distribution of funds from University accounting sources (e.g. research grants). Each faculty member usually has a single RSO. If you are a a student, look for your advisor on the ERSO website to find their corresponding RSO. Otherwise, ask your EECS account sponsor, advisor or supervisor.
