If you have questions about the information in this document please call the Xavier Help Desk at (513) 745-4863. If you are still having difficulties, then appointments can be made between 9:00am and 5:00pm on Monday - Friday (except University Holidays) to verify the network jacks functionality. Note: Recently viruses, spyware, and malware have caused Internet Explorer give "Page cannot be displayed" errors, despite proper functionality of the networking on the computer. The Help Desk can be of assistance in resolving these issues.
Section 1 - Windows XP Professional Configuration Windows XP Professional machines are configured to work correctly on our network once the Ethernet card is installed with the TCP/IP protocol. Here are the steps that you can take to verify that your machine is ready:
You are now ready to use the Xavier Network. Connect your computer to one of the the network jacks in the room using a category 5, 5e or 6 cable - Telephone cables will NOT work and may cause problems on the campus network. Plug one end of that cable into the network card in your computer (it should have a jack that fits the cable plug and it may have one or more lights on the same card). Plug the other end of the cable into on of the network jacks in the room (if there are multiple jacks, any of them should work). If your network card has a green light that is not initially lit when the computer is on, then it should light up when you plug the cable in on both sides and the computer is on. Once the cable is plugged in, reboot your system. You are now configured to use the Internet. See section 3 for more information on this service.
Section 2 - Power Macintosh with OS X Configuration To configure OS X for the Xavier Network, go to ... (Determine that network card & DHCP are confirgured correctly) ... If you have not yet turned in your Application for Network Connection and need help determining your computer's ethernet address, ... (Get adapter address) ... If a problem occurs during this process, please see Appendix B for further assistance in diagnosing the problem. You are now ready to use the Xavier Network. Connect your computer to one of the the network jacks in the room using a category 5, 5e or 6 cable - Telephone cables will NOT work and may cause problems on the campus network. Plug one end of that cable into the network opening on the back of your Mac (it should have a jack that fits the cable plug and it may have one or more lights next to the plug). Plug the other end of the cable into on of the network jacks in the room (if there are multiple jacks, any of them should work). If your network card has a green light that is not initially lit when the computer is on, then it should light up when you plug the cable in on both sides and the computer is on. You are now configured to use the Internet. See section 3 for more information on this service.
Section 3 - Using your network connection service You can use your network service for accessing the Internet, moving files or any other TCP/IP-based service. You will want to point your browser to the Resnet Home Page (http://www.xavier.edu/resnet/) for the latest tips and pointers on using your connection. Available Services There are a number of services that Xavier provides to students that are accessible through your connection. For the latest list, check out the Resnet web site, but some services that you may wish to try out are:
Troubleshooting Problems As you continue to use your service, you may experience problems or slowness with your network connection. If your network connection stops working entirely, please use the troubleshooting sections in Appendix A and B to try to isolate and try to work through the problem. If this does not resolve your problem, you can call the Student Help Desk at (513) 745-4863 for further assistance. If some services work and other services do not work, try to determine what the services that are not working have in common. If you can get to Xavier web sites like the Xavier web server and Xavier's Blackboard web site, then your connection works on campus. If your can get to OARnet's web site, then our Internet connection is working as well (OARnet is Xavier's Internet Service Provider). Beyond that, there may be a temporary outage to a site. Please try again at a different time and if it continues not to work over several days, please contact the student help desk for further assistance. If you are installing new software on your system and it works on campus but not off campus, it may be having a problem with Xavier's firewall. Some software, such as remote control software, may require your system to act as a server. If so, you will need to register your system to have the firewall modified to support this service. Please note that this will not help improve the speed of your application - if the program works at all, the firewall is not the problem (for slowness, see below). Some network software may work fine when connecting to a machine on campus, but may work very slowly when connected to a machine off campus. Xavier's Internet connection is much smaller that our campus network. When many people try to use it at once, there can be congestion and some applications may not work as well. Try using the application at a different time of day (midnight - 6 am are the most available times). If your performance improves, then that was your problem. If your performance does not improve, please contact the Student Help Desk at (513) 745-4863 to be referred to the network engineer for further assistance (please note that some non-academic applications receive a lower priority than other applications and may be slower at most, or even all, times). Xavier's Firewall and Running Servers Xavier has a "stateful" firewall ahead of the campus network to provide some protection against repeated waves of attempts from the Internet to break into systems on campus. The firewall is configured to block any attempt to directly contact your system from the Internet (though all connections from your system to the Internet are allowed, and the return traffic is allowed to pass through). If you wish to configure your system to act as a server for the Internet, you will need to register that system. All servers will be subject to the terms of Xavier's Policy for Responsible Use (including that which bars use of University resources for financial gain or commercial purposes). Systems registered as servers will be required to be kept up to date with the latest security patches to keep them from being vulnerable to compromise. Servers that are compromised (or are shown to be vulnerable to compromise as part of a network security audit) are subject to removal from the network until they are demonstrated to be secure. Multiple Computers Xavier provides one jack per person in network-connected residences. Multiple computers can be used on this jack under the following condition: The student must buy and maintain a Ethernet hub or switch to allow the devices to share the single port. We recommend you purchase a Linksys switch, as these are known to be compatible with the network. Please note that while we will work to make this environment work, Xavier cannot guarantee that all hubs or switches will work on our network. Security on the Xavier Campus Network Xavier tries to make the Campus Network as secure as possible. Systems that are configured with their own IP address will not get an IP address from DHCP and will they work on the campus network. To improve performance, Xavier divides the ResNet population into 9 VLANs. Assignments to these VLANs are based on location. Machines that are in different VLANs may have trouble discovering services on each other. This is to prevent other machines that have viruses, etc. from infecting other systems. Software that is designed to work over the Internet should work fine, but software designed to work on a LAN may have limited problems. If your application is having trouble, please contact the Xavier Help Desk at (513) 745-4863 and ask to be referred to the network engineer for further assistance. We will work with you to get your network application working properly.
Appendix A - Additional Assistance and Troubleshooting for PCs running Windows XP Professional This document assumes that you have your network card installed and configured prior to starting these instructions. Most systems less than 2 years old have an Ethernet card integrated into the system - check with your manufacturer to see if your system has this. Xavier technicians can arrange the purchase of a network card for you, or direct you to a place to purchase a network card. We recommend buying the card from the manufacturer or at least buying a card recommended by the manufacturer - if the manufacturer has no recommendation, then we recommend using an Intel or 3Com card). If you buy a network card from another vendor (other than the manufacturer), then we recommend having them install the card, configure it, and verify that it works in your computer. That configuration should include installation of the card drivers (either through plug and play or through the Add New Hardware control panel) and Microsoft's Internet Protocol (TCP/IP) component. If the card drivers are not installed, you need to refer to the card documentation for assistance in installing those. This may involve configuring these drivers and the card itself to use available IRQs, I/O Range, DMA Addresses and/or Memory Addresses. This process varies tremendously from card to card. Troubleshooting Once the computer is on, go to the Network and Dial-up Connections control panel (it can be found under "Start", "Settings" and "Control Panel"). There should be an icon labeled "Local Area Connection". Double click on this icon and click on the "Properties" button. If the name of the device at the top (labeled "Connect using:") is not the Ethernet card, then click "Cancel" and "Close" and double click on another icon labeled "Local Area Connection". If there are no other icons with that label, then see the paragraphs above for information on obtaining and installing your network card and drivers. Once you have found the correct adapter, click Cancel to return to the Local Area Connection Status window. Be sure that your computer cable is connected to the network jack in the room. If the "Status:" line says "Connected", then look at the numbers in the Activity box. If these are non-zero, then the basic network connection is working. If the status is not connected or the activity numbers are zero, the network card is not seeing traffic. Please call the Student Help Desk at (513) 745-4863 to submit a ticket for a technician to come out and check your jack and cable. If the basic network connection is working, then go to a command prompt by selecting "Command Prompt" from the Start Menu (usually in Start:Accessories). Once there, type "ipconfig /all | more" (this gives one screen of information at a time - hit the space bar to go to the next screen of information). You are looking for name of your Ethernet adapter as labeled "Description". The "DHCP Enabled" line should have "Yes". If not, then go back to the Local Area Connection Properties box from above. Select the Internet Protocol (TCP/IP) line in the middle box and click on the properties button. "Obtain an IP address automatically" and "Obtain DNS server address automatically" should be selected. If they are not, select them, click OK twice and proceed to the next step. If they are, then there is something wrong with your driver installation. Contact your system manufacturer or whoever installed your network card for further assistance. Return to the command prompt window. Hit the space bar until you get a command prompt again. Type "ipconfig /release" and hit return. Type "ipconfig /renew" and hit return. Type "ipconfig /all | more" and hit return, looking for your ethernet adapter again. If during this process you get a message that it cannot find a DHCP server or if the IP address for your adapter does not start with "206.21" please contact the Student Help Desk at (513) 745-4357. Be sure to leave your name, phone number (or other contact information) and the physical address from the ipconfig output in the command prompt window. Once your IP address starts with 206.21 and you can release and renew it, your network connection is working. If you are still having trouble with software after that, it may be a problem with how that software is configured on your system.
Appendix B - Power Macintosh with OS X Troubleshooting If you are getting an error message about network sockets when running a TCP/IP application (such as Netscape, Telnet or Fetch) or the software is giving an error message about the DNS service, then there is some problem with your TCP/IP setup. The first step is to look at the network card on your computer once the network cable is plugged in to both the wall and the computer and the computer is turned on. If it has small lights next to it and the lights are not on, please call the Student Help Desk at (513) 745-4863 to have us check the jack. Note that the problem can also be a bad Ethernet card. Next try checking TCP/IP connectivity. ... (Check IP for OS X) ... If the IP address has all 0s in it or says will be supplied by server or starts with 10., then please contact the Student Help Desk at (513) 745-4863. We will need your name and Ethernet card address. If TCP/IP still isn't working, then the problem might lie with the network jack, the system software or with your network card. Call the Student Help Desk at (513) 745-4863 for further assistance. If the card did not come with your Macintosh, contact the vendor who sold you the card for information on repairing the card or for any special software that is needed.
