The UAB network will experience one, and possibly three, 2-4 minute outages between 6 and 9 a.m. on Saturday, August 20, as UAB IT performs annual network upgrades.

UAB IT has scheduled the outage while classes are out of session to lessen the impact on campus.

The UAB Hospital network will not be affected by the outage.

Portions of two streets on campus will be closed for one more night, Friday, July 10, as part of the completion to a project to upgrade UAB's fiber network.

Crews were delayed and will finish paving Friday night.

From 7 p.m. to 1 a.m., the following roads will be closed: 

• Ninth Avenue South between 17th Street South and 19th Street South
• 18th Street South between University Boulevard and Ninth Avenue South

Access to the following buildings may be partially or fully affected:

Rust, Research Support Building, Southeastern Biosafety Lab (SEB Lab), 1715 Building, Ninth Avenue Office Building, School of Nursing, School of Public Health, Learning Resource Center, and 19th Street Parking Deck.

The City of Birmingham will be milling and paving those streets following an upgrade to the underground fiber hub.

How do I find my IP Address and Network Settings?

The IP Address and network settings are used for addressing and routing over an Ethernet network. It is your computer or printer's logical (virtual) address. An IP Address looks like this: 138.26.1.201

 

SOLUTION:

Windows 7, Vista, XP

1. Open a DOS Window (Start -> Programs -> Accessories -> Command Prompt).
2. Type the command: ipconfig -all | more.

Macintosh

1. Open System Preferences in the Dock.
2. Click the Network tab.

If the computer is behind a firewall

1. Go to www.dpo.uab.edu and click the "What's my IP?" link.

In some cases when using a VPN over a network connection with a Windows XP computer, the VPN Session will disconnect after a period of inactivity (typically 10 to 20 minutes). This problem is caused by the Windows Service Pack 2 Firewall settings.

To fix the problem, the Windows Firewall needs to have the Cisco VPN Client program specified as an Exception:

Click on the START tab, and select:

Control Panel -> Windows Firewall

The following screen will be displayed. Click On (recommended) if not already on.

Click the Exceptions Tab which will bring up the following screen:

Click Add Programs which will bring up the following screen:

Click Browse and set the directory to look in to C:\Program Files\Cisco Systems\VPN Client.

Highlight the cvpnd program (single click), and then click Open .

Click OK as necessary.

At this stage the cvpnd program should have an entry as above. Click on OK to finish.

These settings for the Windows Firewall will stop the VPN session being terminated after 10 to 20 minutes of inactivity.

Every unit at UAB with devices connected to the UAB campus network should have a "network contact" person, even if there is no department server or local area network. At least one person within your department should be designated to be responsible for communicating your requests to DC/NS, and for assisting network users with basic configuration, software installation, computer training, and problem solving.

Designate an official "network contact" person for your department.

• Each department or unit at UAB should have an officially designated "network contact" person.

   

• The dean, chairman or director designates who is to serve as "network contact" for your unit. The dean, chairman or director should send either a written memo or an e-mail message to userservices@uab.edu indicating who is to be considered the official contact person.

   

• Data Communications / Network Services (DC/NS) recommends that the contact person be a trained computer professional.

   

• If the "network contact" person is not a UAB employee, the department should additionally designate a contact person who is a UAB employee.

   

• The "network contact" person should have access to a UAB e-mail account (hostname ends in uab.edu). All requests to DC/NS must be submitted via e-mail (userservices@uab.edu), and for security reasons these must originate from a server registered through DC/NS.

   

Notify DC/NS when there is a new "network contact" person, or other changes in responsibilities.

• When there is a change in personnel or responsibilities within your department, DC/NS should be notified. The previous "network contact" may send a message to userservices@uab.edu introducing the new person. If no replacement arrives before the old person departs, the last "network contact" should hand this function to their supervisor or other person in the department, who will then hand the job to the replacement person when they arrive. IP records, and any other records, should be turned in to the department for safekeeping.

   

• If the "network contact" left UAB without notifying DC/NS, the dean, director or department head should contact DC/NS with the name of the replacement contact person.

 

Some typical duties of a department "network contact" include:

• Manage a block of IP (internet protocol) numbers given to the department by DC/NS, and maintain records of the location for each IP number used. Requests for new IP numbers should be submitted by e-mail to mailto:userservices@uab.edu?subject=Request new IP numbers

   

• Request registration of host names in the UAB DNS (domain name service). Requests for DNS registration should be submitted via e-mail to userservices@uab.edu

   

• Communicate network problems to DC/NS, and assist in trouble-shooting and problem resolution. Please call 4-3540 to report network communications problems, and call 4-7777 to report network wiring problems. You may also report problems via web interface.

   

• Request and properly configure other net-wide addressing, such as Novell server names and addresses, and Appletalk zone numbers and names. Net-wide addressing requests should be submitted via e-mail to userservices@uab.edu

   

• Coordinate equipment installation and relocation with DC/NS.

"Strange network problems" can be caused by DUPLICATE IP ADDRESSES. If the workstation can send traffic off its segment to another subnet in our 138.26 class B address range but can not get to a location off campus, it is very possible that the workstation IP address has been incorrectly set to use the campus gateway (138.26.1.1) instead of its own address. Problems within your building network that affect only one or two machines can be caused by duplicate addresses, also.

SOLUTION:

One way to check for duplicate IP addresses is to look in the arp cache of the machine having problems. In Win 95/98 or NT, at the DOS prompt type the command "arp -a". For entry of 138.26.1.1 you should see a MAC address starting like 00-00-a2....

You can report the MAC address you find to UserServices, and we will help you track down the "offending" machine.
