Personal Computer

Beginning from fall 2007, new students are now encouraged to buy a personal computer (laptop). Unfortunately only limited support on the PCs are supported. This is as follows:

Please note that we recommend using ThinLinc to connect from your local computer to the G-Bar computers.

All operating systems

The wireless network

The wireless network (a.k.a. wifi network, Danish: det trådløse net) is accessible in almost all of DTU's buildings. Around examinations the wireless network may be disabled in some buildings.

How do I get access to the Wireless Network?

The network has the ESSID "eduroam" and is encrypted. In order to get access to anything outside the wireless network (including the G-Bar servers, web pages etc.) you have to authorize your computer. This is done during the login to eduroam - see the setup guides for eduroam for more information.

The legacy ESSID is "dtu", which can be used in case eduroam does not work on your computer. In order to use this ESSID, you must authenticate your computer at https://login.wireless.dtu.dk/, which is an encrypted page.

Can I access my student e-mail from my laptop, when I am at DTU?

Yes, you can. Follow the description for checking your mail at home here. If the SMTP server of your internet host doesn't work at DTU, you may use smtp.wireless.dtu.dk instead. Notice that smtp.wireless.dtu.dk won't work, when you are not using the wireless network of DTU (either eduroam, or the dtu network). Please see [1] for more information.

Sometimes when I surf the wireless network, the authorization pages pops up again. Why?

This happens when your computer gets a new ip address. This is most often related to a problem on your computer:


How do I print from my computer on a G-Bar printer?

Please see this page.

Windows specific

How do I copy files from/to my local computer to/from the G-Bar servers?

We recommend using External File Access for a user friendly interface or WinSCP for a terminal.

I am having trouble installing Maple on my own computer

There has been noted several problems while installing and/or upgrading Maple. Especially with the combination of Maple 11 and Windows Vista. Here are some pointers, though:

Internet connection

Please note that you have to be connected to the internet in order to activate Maple. If you (for some reason) do not have internet access on the computer you are installing Maple, an offline registration of Maple can be done at Maplesoft's offline registration page.

Maple installation failed. Now Maple can neither be reinstalled nor un-installed!

This may happen sometimes. The installation process failed (for no apparent reason) installing some, but not all files. Maple will not install (because it can see it is already installed) and it cannot be un-installed (because the setup is incomplete). You have to completely clean your system of Maple:

  1. Delete Maple program files from your computer
    1. Maple is (probably) located under C:\Program files\Maple 11
    2. Delete this folder. (Windows may put out an alert. Just ignore this).
  2. Delete all Maple related from the Windows registry
    1. Start the Windows Registry Editor (Task manager => File => run => regedit)
    2. Make a search (F3) for the word "Maple" and delete what you find.
    3. Repeat the previous step.
  3. Delete Maple from 'Add/Remove programs' menu.
    1. Open the "Add/Remove programs" menu (From the control panel)
    2. Locate Maple (if it is there) and un-install it. (Windows will put out an alert. Ignore this)

Now you are ready to reinstall Maple.

Java

Maple uses Java for its GUI. Java is bundled with the Maple installation CD, but some have reported trouble with Java not being installed correctly while upgrading Maple. In this case you can try to download the newest version of Java from the Java website.
