Welcome to the IQ computing environment. By finding the IQwiki you have already finished the first step to get started. The EDV section contains most necessary information information concerning computers in our institute. This page will give you some basic information about our computers and servers.

• Get an account: Ask one of the IQ-Admins to get one.

• Please read the Password Policy: Our servers are accessible worldwide. So the choice of a secure password is crucial! Passwords have to be eight characters or longer. These characters have to include lower case letters, upper case letters and numbers.

• Get an email account: This should be part of your Laufzettel, handed out to you by Frau Kaisik. Note, that your request won't be submitted until you have finished your Laufzettel and have returned it to Frau Kaisik. For information about mail configuration read the IQwiki page on Mail Configuration.

• Read the Introduction to AFS: AFS is a distributed file system, which allows access to your files on the server. This will give you an overview over the basic features of our file server.

• Printing: We provide several printers in our institute and can also use some RRZN printers. For more information read PrintServer and PosterDruck.

• Software: See SoftwareBestand for a list of software used in our institute.

In order to connect your computer to our servers and services you need to perform the following steps:

You can use the university's license for Sophos Antivirus software. See Anti-virus software for details.

• <fc #ffa500>NOTE:</fc> You can skip everything below, if you only use the university's WiFi.
• You need a valid MAC address to connect your computer to the institute's network. See here, how to find your MAC Address.
• Communicate the following information to one of our admins.
  • MAC Address: Preferrable in AB:CD:EF:01:23:45 notation, rather than AB-CD-EF-01-23-45.
  • Experiment / Workgroup
  • Computer Type
    • Lab (Lab computers & devices)
    • Office (permanent Desktop PCs)
    • Laptop (Payed by LUH)
    • Privat (Your privat Laptop)
    • Guest (Any temporay guest)
    • Server (Computing devices & Servers)
    • Printer
    • USB Ethernet Adapter
  • Computer Name
    • For Lab, Office, Laptop, Server: Exact Hostname
      • <fc #ff0000>Give that device a proper hostname/computer-name</fc>. desktop-1gk4d65 (“Windows generic”) or rasel-mbp (“Apple generic”. mbp = MacbookPro) should be avoided.
      • Stick to the name convention of your experiment like vlbai-oc-05 or qc-oc-13 and so on.
    • For Privat: YourName-PRIV
    • For USB Ethernet Adapter: YourName-USB or Hostname-USB
  • User
    • Ideally the IQ-Account username that will use that device or any other responsible person
    • For Guest devices: If that user gets an IQ account, use this. Otherwise: The person, who invited the guest
  • Building number & <fc #ff0000>Room number</fc> (Use this sitemap)
    • Some common Building Numbers down here
      • LUH: 1101
      • HITec: 3402
      • HITec Offices: 3406
      • LNQE: 3430

• Configure Kerberos and AFS: Once configured this will work not only from inside the institute's network, but from everywhere in the world. See Install AFS on your computer for details.

• VPN Client: Some services, as e.g. the license servers are only accessible from inside the university's network. From outside you can use a VPN tunnel to the univerity's network. See http://www.rrzn.uni-hannover.de/netz_vpn.html for details.

• SSH: You can use SSH to access your files. From inside the institute you can access afs1 with your Kerberos password. You can ask an admin to get ssh permissions for web.iqo.uni-hannover.de which is accessible from everywhere. It is however discouraged to use direct SSH via web.iqo.uni-hannover.de. You drive better by using OpenVPN and then use SSH against afs1 or any other service within the IQ network, that is SSH enabled.

• Login with IQO accounts: If you want to allow login to your computer with IQO accounts, you can also use SSH for user authentication. A description for Windows can be found here. Note: This allows everyone with an IQO account (even guests) to login to your desktop!
