| − | This category covers how to connect ''your own'' computer (desktop/laptop) to the CS Network over at the new Malone Hall.
| + | ==INTRO== |
| | | | |
| | | | |
| − | ==Overview==
| + | This category includes links on how to connect ''your own'' computer (desktop/laptop) to the CS Network over in Malone Hall. ''We do not support networks outside of Malone Hall.'' |
| | | | |
| − | There are three main networks in CS at Malone Hall. They are:
| + | '''''But first,''''' please read: |
| | | | |
| − | '''Public CS Grad/Research Net''' (128.220.35.x) - Uses IP addresses that are ''accessible from the Internet'' (like the current Grad Net in Croft/Shaffer)
| + | :[[Networking at CS - Overview]] |
| − | | |
| − | '''Private CS Grad/Research Net''' (10.161.159.x) - Uses IP addresses that are ''only accessible from within the Hopkins network (and Hopkins VPN)''.
| |
| − | | |
| − | '''CS Undergrad Net''' (128.220.224.x) - Uses IP addresses that are ''accessible from the Internet''
| |
| − | | |
| − | The two Grad/Research nets are only accessible via network jacks in Malone Hall in CS work areas, except for the CS Undergrad Lab (Malone Hall 122). The CS Undergrad Net is only accessible via network jacks in the new CS Undergrad Lab.
| |
| − | | |
| − | ==Network Jacks (Wallports) In Malone Hall==
| |
| − | | |
| − | Each network jack in your new Malone ''office'' will go to exactly one of those two networks (Public ''or'' Private Grad Net), so care will be needed to connect your computers into appropriate jacks. (If you have a system that will reside in the Malone ''server room'' instead, info can be found [[#Additional_Considerations_for_Servers_Residing_in_the_new_Malone_Server_Room|here]].)
| |
| − | | |
| − | Any given network jack can be changed from one network to the other (i.e., ''public to private'' or ''private to public'') with relatively little difficulty with an emailed request to [mailto:support@cs.jhu.edu CS Support]. We will pass on your request to JHU Networking. JHU Networking will be administering the network configurations; here is their current plan:
| |
| − | | |
| − | '''Even-numbered jacks''', by default, are connected to the '''''Public''''' CS Grad network, 128.220.35.x
| |
| − | | |
| − | '''Odd-numbered jacks''', by default, are be connected to the '''''Private''''' CS Grad network, 10.161.159.x
| |
| − | | |
| − | == Public CS Grad/Research Network Details ==
| |
| − | | |
| − | The '''"Public" CS Grad/Research Net''' uses IP addresses that are directly accessible from the Internet. It is useful for servers that need to be widely accessible or for systems that people need to connect to without going through the Hopkins VPN. (For example, if you need to ssh into your work machine from out on the Internet, your work machine needs a public IP address.
| |
| − | | |
| − | Systems on the Public Grad Net can freely communicate with systems elsewhere on the Hopkins network, including systems on the Private CS Grad Net.
| |
| − | | |
| − | In order to set up a system on the Public Grad Net, you will need to fill out the [http://www.cs.jhu.edu/ip-address-application Static IP Address Application Form] and be approved. Your approval will include instructions on how to set up your system.
| |
| − | | |
| − | Because systems on the Public Grad Net are exposed to the Internet, they are expected to be managed in a way that preserves their security and the security of the Hopkins network. The Network Security Team (part of the [http://www.it.jhu.edu/ IT@JH] group, ''not'' CS) may periodically perform security scans of systems on the Public Grad Net. If they determine that there are security problems with a system, they may disable all Internet access for that system until the problems are resolved.
| |
| − | | |
| − | == Private CS Grad/Research Network ==
| |
| − | | |
| − | The '''"Private" CS Grad/Research Net''' uses IP addresses that can only be directly accessed from either the Hopkins network or the Hopkins VPN. It is useful for systems that do not need to be accessed from the Internet, like desktop computers or printers. The private addressing used on this network helps keep the systems a little more secure, since no one on the Internet can contact them directly.
| |
| − | | |
| − | You can connect your system to the Private Grad Net by following the instructions at [[Connecting To The CS Grad Net Using DHCP]]. That will give you a dynamic IP address. If you need a static IP address, fill out the [http://www.cs.jhu.edu/ip-address-application Static IP Address Application Form], making sure to specify that you want a private static IP address.
| |
| − | | |
| − | == CS Undergrad Network IPs ==
| |
| − | | |
| − | Starting after Thursday, August 7, 2014 (after the Croft CS Ugrad Lab moves to Malone Hall), the '''CS Undergrad Network''' is only available via wallports in ''Room Malone Hall 122 (the new CS Collaboration Room. Malone Hall 322 will house additional Ugrad Lab systems, but that room is not ready as of this writing).'' and only using [[Connecting To The CS Ugrad Net Using DHCP|CS's ''Dynamic'' DHCP service for the Ugrad Net]]. There are no static IPs granted for the CS Ugrad Net.
| |
| − | | |
| − | <!--
| |
| − | The '''CS Undergrad Network''' is only available via network jacks in the undergrad labs in Malone 122 and Malone 322. Use the instructions at [[Connecting To The CS Ugrad Net Using DHCP]] to connect to this network. All access on that network uses dynamic IP addresses; we do not issue static IPs for it.
| |
| − | -->

| − | | |
| − | == DNS Servers to use when on the CS Network ==
| |
| − | | |
| − | Primary DNS: '''128.220.13.50'''
| |
| − | | |
| − | Secondary DNS: either '''10.200.1.1''' or '''10.200.2.2''' -- your choice.
| |
| − | | |
| − | DHCP-provided CS IPs will automatically receive a primary DNS server of 128.220.13.50 and a secondary DNS server of 10.200.2.2.

| |
| − | | |
| − | '''CS does ''not'' provide wireless capability.''' We suggest connecting to [http://www.it.johnshopkins.edu/services/network/wireless JHU's '''hopkins''' wireless network] if you would like to wirelessly connect to JHU. (We recommend you do not connect to JHU's "JHGuestnet" access point, since it limits your ability to connect to sites within JHU. So, use "hopkins" instead.)
| |
| − | | |
| − | If you have problems connecting to JHU's "hopkins" wireless system, you can either contact the JHU Helpdesk at 410-516-HELP or, you can send e-mail to [mailto:wirelessteam@jhu.edu '''wirelessteam@jhu.edu'''] for further assistance. Be sure to tell them where on campus you are experiencing the problem. They might also require specific information about your computer, including its wireless interface's MAC address.

| − | == Security Note ==
| |
| − | | |
| − | All computers that connect to the CS Grad/Research or Undergrad net should be at their latest security levels and should be configured to prevent viruses, etc. For antivirus software, please see the [http://it.jhu.edu/antivirus JHU Antivirus webpage].
