How to get at the virtual UWP2

Use Firefox to connect to https://uwp.rug.nl, log in and choose your application/desktop. This use HTML5, but doesn't support a direct connection to your local drives.

Issues with the ICA client

The ICA client has issues. Only under Ubuntu Precise did we fix it enough for it to work. We saw it work on Debian Wheezy too.

The packages we offer are 32-bit packages, and they draw in a lot of 32-bit dependencies on your 64-bit machine. Still there is no point in trying to install the 64-bit packages Citrix (or help.ubuntu.com) offers. They contain exactly the same 32-bit executables and libraries, only in a .deb wrapping that says they're 64-bit. Apt goes by that information and fetches all the wrong 64-bit dependency libraries, and things'll only work if you manually install ia32-libs and some extra dependencies that Citrix failed to mention. Which our package did automatically in the first place. And then still you'll have a messed up apt.

The LWP admins take no reponsibility for the Citrix ICA client. It violates the Debian/Ubuntu packaging standards and common sense. In particular:

• The package is made up of executables compiled on Red Hat (perhaps 6.0), so libraries may be the wrong version or missing altogether.
• The maintainer scripts are lengthy and utterly untested on Ubuntu. (Judging from the fact that they break on failure to recognize the 'amd64' architecture of Ubuntu machines). They change other applications' trees, and may try to read/write users' homedirs if they get the chance. (On the LWP, they don't get a chance because root cannot read/write on Kerberized NFS4 in our setup.)
• The client may break without warning at any time.

We have offered our help to Citrix, but received no response so far. There is nothing more we can do. Service calls regarding the Citrix ICA client should go to the UWP2 group.

Tips & Tricks

If you get the Citrix Receiver a.k.a. the ICA Client to work you can add the following to it's config. This will make your local drives available.

• How to connect your local drive(s) to https://uwp.rug.nl.

Note: On the LWP this is done automatically!
After installing the "icaclient" (and it's dependency), there should be a file "~/.ICAClient/wfclient.ini" in your home dir. Open it with your favorite editor and add something like the following, somewhere underneath the "[WFClient]" header:

DrivePath?=/path/to/your/drive
DriveEnabled?=Yes
DriveReadAccess?=0
DriveWriteAccess?=0

• ?: choose any UPPERCASE letter that is not already in use by Windows.
• DriveEnabled: Yes to automatically mount in Windows on login.
• DriveReadAccess: 0 is yes
• DriveWriteAccess: 0 is yes

• How to use x-deep 32 to get X applications under Windows to work:

• In PuTTY go to Connections -> SSH -> X11 and check enable X11 forwarding.
• Next, login to your machine of choise like you would normally do.
• Now the connection is set up we can start the x-server. Go to Internet en Communication -> x-deep 32 and select x-server.
• A window appears in which you have to select what network interface to use. Just check the box Never show this dialog box, and always accept request from [ANY] network interface... Unless you have more interfaces and know what they are for. Then click Select.
• A popup window appears, remove the check for Always check for XDM enabled hosts on startup. and click OK.
• The x-server window appears. This is however an x-server without a window manager, so you won't be able to move the windows. To enable this, right click in the title bar and select X-server Menu -> X-server Options -> select the Window Modes tab. Beneath the Multiple Windows Modes heading, select Multiple MS Window Mode and click OK.
• To open your X applications, in your PuTTY session type xterm or whatever application you want and it should start in your Windows session. If you don't want to lose your PuTTy terminal type xterm &.

Other Ubuntu/Debian versions

The packages we use on the LWP are 'uwp' and 'icaclient'. If you are not on the LWP but inside the RuG network, you can install them after you put the following line in your sources.list:

deb http://deb.rug.nl/rug/ubuntu/precise lwp-testing main

Some things to be aware of:

• Firefox must be installed *before* the ICA client is installed. (The ICA postinstall script changes settings in the Firefox directories.)
• The icaclient package we use was fixed by us.
• You may want to avoid fetching any other packages from our repository. If so, be sure to disable the repository again after fetching the packages, and avoid any upgrades until you do so. (Or better yet: use apt pinning.)

There are other sources for the ICA client too. From the Citrix site (these have issues, see below), or from help.ubuntu.com (also fixed, but a bit different from ours).
