    Networking Issues

    I recently arrived in Ghent, Belgium, at the university here. In order to get online in the student residences, we have to use an ethernet cord, and when you plug in the cord at first, you can only visit the webpage for the school's IT helpdesk (http://www.helpdesk.ugent.be/vpn/en/asa.php) and download the "Cisco AnyConnect Secure Mobility VPN" which then allows you to log in and get online.

    My machine is set up to dual boot Windows 7 and Kubuntu 14.04. Booting under Windows, this procedure works just fine. Booting under Kubuntu, when I plug in the cable I get a network icon with a little yellow question mark and it says "disconnected", and I can't even visit the help desk site. I don't think it is a driver issue, as I was able to make a wired connection to my parents' network over the holidays without any trouble.

    I tried downloading the tar.gz file from the helpdesk, but I don't really know that much about how to use them and I couldn't make it work; and anyway I don't think it will work unless there is some kind of connection.

    I tried contacting the IT help desk here, but they said I would have to give them my computer overnight (don't want to do that because it has sensitive/personal information and would have to give them my logon password), and when I asked for an alternative, like bringing it in during opening hours, they told me "help desk is a privilege not a right" and hung up the phone.

    Does anyone have any idea where I could begin to diagnose the problem?

    Thanks for your help, I really appreciate this forum and all the help that everyone here provides.

    Try plugging in the cable before you boot Kubuntu.

      So I was able to install and run the VPN software, but the cable connection still doesn't seem to work, even if I plug it in before booting Kubuntu.

      I'm guessing it's not a hardware problem since I can connect while running Windows 7; could it be a driver? What should I check next?

        I think I'm confused. How were you able to install and run the VPN software if you are unable to connect via your wired connection to the school's IT help desk using Kubuntu? I thought you had to download their version of AnyConnect from that webpage. I doubt it is a driver issue since you were able to successfully connect using your wired connection to your parent's network. If they are on a Windows Domain it may be a security issue, especially since that is the only webpage you can connect to. I think they might have to give you permission to connect. Out of curiosity did you click your Networks icon on the task bar and then for your wired connection click "Connect"?

          I was able to download the Linux version of the VPN software while running Windows, then move the file over to the Kubuntu partition and install it.

          Unfortunately there is no option to "connect" to the wired network, the only thing that shows up in the Networks icon is nearby wireless networks (which I can't/don't want to connect to).

          I will try to see if there is a permission issue next week, hopefully someone else is working the help desk then ;-)

            If you don't see a wired connection in Network Manager, then your school probably cannot assign a DHCP address. You may need to add a wired connection or fix /etc/network/interfaces. Other guys on this forum are probably a bit more knowledgeable than me. What do you see when you enter ifconfig in a terminal?

            This link may help.

              If you can get someone to get you the specific connection info or see if there are any manual settings you can view form Windows, you can add a new Openconnect connection. You'll likely need to install the package network-manager-openconnect

              Click the networking icon in your systray, then click the wrench icon at the top to open the connection editor, and then click the Add icon, and select "openconnect" down under the VPN section. Then you'd need to enter the connection info you need. I have no idea what all the sections mean\ or what you need and don't need to set.

              However, you can still use the cisco client you already installed. It is a commandline tool. I searched the website briefly and found this page that shows how to set it up, but a part are outdated:
              http://helpdesk.ugent.be/vpn/en/handmatig.php

              basically, make sure you have installed the 32 or 64 bit software as appropriate for you.
              You probably don't need to follow steps 1 through 3 if you have installed it already.
              For step 4 do this:
              In the terminal, you type this command instead of the one the page gives:
              /opt/cisco/anyconnect/bin/vpn
              Then you will see:
              Code:
              VPN>
              Enter connect asavpn2.ugent.be
              You then will enter your username and password if you are actually connected but I really don't know. It connected from here in the US and I got the username prompt.

              Using this tool requires you keep that terminal open. The connection disconnects if you close it.

              If you can get the connection details, using the the systray network manager applet is easier and better overall as you connect and manage things there instead of the command line.


              I do wonder why they want your laptop overnight unless they want to install and set it up for you.

                  Booting under Kubuntu, when I plug in the cable I get a network icon with a little yellow question mark and it says "disconnected", and I can't even visit the help desk site.
                  I think we are missing the important bit here - the ethernet connection is not working, which is why you can't connect to the VPN. When you get the yellow question mark on your networking icon, when you click it, you should see something similar to "wired connection1 ". Now, hover your mouse over it and then click the 'connect' button that you should see, and see if that works. If so, you can then connect to the VPN using the cisco program or adding a new openconnect in your connection manager



                  Dang I forgot that virtualbox recording does not include the mouse without fiddling ;(

                    claydoh, I believe his problem is that he does not see the wired connection so he cannot simply click connect. I think he needs to add a wired connection as you showed toward the last of your video. (Restrict to eth0 which is the listed device). After adding the device he may be able to connect immediately or may need to reboot. By the way, open-connect is the way to go if possible. I use it daily.

                      Yes!! This solved it! And made me feel a little foolish for not trying it first :-)

                      But that's just part of the learning process I guess.

                      Thanks to all for your help, I really appreciate it!
