| − | <!-- The network at Malone Hall will be a little different than the one currently active in Croft Hall and Shaffer Hall. This page documents what you need to know and what you need to do to move your systems between the two.-->

| − | == About the Network ==
| |
| − | | |
| − | In Malone Hall, there will be two CS faculty/graduate networks:
| |
| − | | |
| − | '''Public Grad Net''' - Uses IP addresses that are ''accessible from the Internet''.
| |
| − | | |
| − | '''Private Grad Net''' - Uses IP addresses that are ''only accessible from within the Hopkins network (and Hopkins VPN)''.
| |
| − | | |
| − | (There is also an Undergrad Net, but that will be discussed at a later time. Also, JHU is expected to be providing their wifi system, including the '''''hopkins''''' SSID, at 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]. JHU Networking will be administering the network; here is their current plan:
| |
| − | | |
| − | '''Even-numbered jacks''' will be connected to the '''''Public''''' CS Grad network
| |
| − | | |
| − | '''Odd-numbered''' jacks will be connected to the '''''Private''''' CS Grad network.
| |
| − | | |
| − | We anticipate that a number of these network jacks will need to be reconfigured as part of the move-in process. Again, such changes can be effected by emailing [mailto:support@cs.jhu.edu support@cs.jhu.edu] with the jack number and the network to which it should be connected (''Public'' or ''Private''.)
| |
| − | | |
| − | Any system on one of the networks will be able to communicate with systems on the other network. This means that you can, for example, print from a server on the public network to a printer on the private network.
| |
| − | | |
| − | == Your New IP Addresses ==
| |
| − | | |
| − | To see your new IP address assignments, please consult the "[https://www.cs.jhu.edu/malonemove/new-network.html New Network Addresses]" page. You will have to log in with your JHED ID before you can see the page.
| |
| − | | |
| − | == What You Need to Do ==
| |
| − | | |
| − | To ensure that the transition is smooth and effective, we'll need a few items from you.
| |
| − | | |
| − | ''First,'' please arrange to visit your space in Malone Hall at least a couple of days before your move. Figure out where your computers will be going, and determine whether the default network jack assignments will work for you. Again, '''even-numbered''' jacks will be connected to the '''''public''''' CS Grad Network and '''odd-numbered''' jacks will be connected to the '''''private''''' CS Grad Network. If you need some jacks changed, please email [mailto:support@cs.jhu.edu support@cs.jhu.edu] as soon as possible with the jack numbers and the networks (''Public'' or ''Private'') to which they should be connected. ''Be aware that we will forward your request to JHU Networking, so we must wait until they perform the change. So, try to check your new spaces as soon as it is made available to you.''
| |
| − | | |
| − | ''Next,'' please let us know ''when'' you will be moving, as precisely as possible. We would ideally like to know the ''date'' on which your computers will be moving, the ''time'' you will be shutting them down, and the ''time'' you expect to be turning them back on. You see, although your Malone IP address is assigned to you prior, we can't have same .cs.jhu.edu hostname assigned to different IPs between the two different buildings (Croft/Shaffer ''and'' Malone) at the same time. So, we must plan to make DNS hostname mapping changes during the time the systems are off, so that by the time they're back on again in Malone, their DNS hostnames will point to their new Malone IP addresses. To provide us this timing info and to coordinate the DNS hostname mapping changes, please email [mailto:support@cs.jhu.edu support@cs.jhu.edu] (and not our individual CS IT staff members.)
| |
| − | | |
| − | ''Finally,'' you will need to make sure your systems are configured with their new network information. If you indicated that you will be using DHCP in Malone Hall, all you need to do is connect your systems to appropriate network jacks (even/public; odd/private), and turn them on. They should get all of the correct information automatically. You can check the "[https://www.cs.jhu.edu/malonemove/new-network.html New Network Addresses]" page to see whether we believe you will be using DHCP or not.
| |
| − | | |
| − | ''NOTE'': If you plan to use DHCP but you haven't set it up yet, you can do so right now; our Croft/Shaffer DHCP server has been configured to serve the ''current'' Croft/Shaffer IP addresses for everyone who indicated that they'd be using DHCP.
| |
| − | | |
| − | If you will ''not'' be using DHCP at Malone Hall, you will have to configure your computers manually when you get to Malone. Use the IP address listed for your computers on the [https://www.cs.jhu.edu/malonemove/new-network.html New Network Addresses] page and the rest of the network information listed on the [[Connecting To The CS Grad Net Without DHCP]] page.
| |
| − | | |
| − | == Additional Considerations for Servers Residing in the new Malone Server Room ==
| |
| − | | |
| − | There are no network jacks in the new Malone server room (Malone Hall Room G-29). Network cables will be run from above to the server racks. If your server(s) is transferring into the new server room and needs to be on one of the CS networks (''public'' or ''private''), '''''you will need to discuss your network needs and make arrangements with the JHU Networking group as soon as possible for your move''''', if you haven't already done so. In most cases, JHU should be able to run a single cable from their network rack to your systems rack for each network you need to use. (So if you have a rack containing devices using both public and private addresses, they'll run two cables, one for the public network and one for the private network.) You will probably need to connect that cable to your own switch on your rack and then plug your servers into that switch.
| |
| − | | |
| − | Again, if you have special networking needs for servers you're hosting in the new Malone server room, you need to contact JHU Networking directly to discuss those needs as soon as possible, so that they are prepared come move-in time.
