Can I have multiple IP addresses?

There is a limited amount of IP address space available to ResNet. This allows users to have only one address. All ResNet users are limited to registering one system via the ResNet registration system. This should have no affect on the majority of users. If you need to hook up more than one device, you will need to purchase and use a NAT/masquerading box. For more information on NAT, see question on NAT devices below.

Can I use IP masquerading (NAT)?

Yes, you may. Only one Ethernet device may be connected to a ResNet port. IP masquerading or NAT box (a method to allow multiple devices to use one IP address) is currently the recommended way to have multiple devices connected to ResNet. NAT is allowed in Resnet to allow an individual student to attach multiple devices. For example, a desktop machine, laptop and printer. The NAT device must be configured to not allow wireless connections. And the device may not be used to connect devices from multiple students on the same network connection. Any of this activity will result in the immediate termination of the network connection.

For help in setting up a NAT device, please see Connecting Multiple Devices: NAT Boxes and Routers.

Can I use a hub, switch or wireless access point in my dorm room?

Attaching Unapproved network devices (e.g. wireless access points, hubs, switches, and DHCP servers) in the Texas A&M Residence halls is strictly prohibited. These devices can cause disruptions, security risks and outages for ResNet users. Using these devices on ResNet can cause the user's port to be disabled. The user will need to contact Help Desk at 979.845.8300 to re-enable connection.

What ports are open to ResNet through the campus firewall?

Due to changes in network configurations, students in the Residence Halls will no longer be allowed to request a port opening for computers on ResNet. This means that no computer on ResNet can be accessible from off campus.

What activity on ResNet will get me in trouble?

Students are subject to rules of responsible computing, as described in http://student-rules.tamu.edu. Activities including but not limited to the following are in violation of the student rules: Any attempt to subvert the campus firewall (including running a service on a port other than the well-known port for that service), network denial-of-service attacks, unauthorized possession of copyright material, any attempt to compromise the security of any other computer; distribution of unsolicited bulk or commercial e-mail or use of any A&M resource for commercial use.

If you are found to be performing any of the actions listed, your (and possibly your roommate's) ResNet access will be suspended. You will also be subject to disciplinary action via Student Judicial Services.

What happens if my machine causes a problem on the network?

If the Network Group determines your machine is causing a problem on the network (perhaps due to configuration error or a hardware problem), your ResNet connection will be shut down until the problem can be addressed. If the problem was caused inadvertently, no disciplinary action will result.

Can I give access to my friends off campus?

No. Your computer is for academic use. If someone off campus needs access for an academic purpose, the academic department involved can provide the necessary access.

Where do I get help with a ResNet related problem?

All support questions should be directed to Help Desk Central:
Phone: 979.845.8300
Email: helpdesk@tamu.edu

They will help you over the phone or by email immediately, or open a problem ticket for a support person to contact you later.
