Thinlinc: Terminal Server Environment

Cheat Sheet

• Accessing the same session locally (at the institute) and remotely (for example at home) - no hassle anymore with locked Firefox profiles.

• IT Support: on your request, it is possible to 'shadow' your session to the IT group - in case of any trouble - just call the IT by phone.

Connect Session

• Use any of the Terminals at the institute or use the 'native client' (see below) application on your own computer (Internet access is needed).
• Just login.
  • An already existing session (in the background or on another terminal) will be moved and reconnect you.

• Server: tl.math.uzh.ch

• By default, the Session is fullscreen. To change this, open the 'popup menu' by pressing F8 and change Full screen.

Disconnect Session

• Press F8 to open 'popup menu' and choose disconnect.

  • If you need the 'F8 key' in an application, assign another key for the popup menu. To do so: F8 > Options > Options > Popup Menu Key. The new setting is only active during the recent connected session.

Get a new and fresh session

Sometimes it happens that your session is locked for some reason (crashed apps, quota problem, ...). A session disconnect / reconnect does not improve the situation.

Please check the option End existing session in the tlclient login window and log in again. Your old session will be killed and a new session will be created. All open applications will be terminated. Open files might be lost. Use is with caution!

• This option is not available via Webaccess.

USB sticks: Terminals in building Y27

• If you plug in a USB Stick at the terminal, there is no window, which opens automatically.

• Plugged in USB sticks or ext. hard drives will appear in your home directory under the folder thindrives.

• Open a Filemanager (Menu: Places) and navigate to your 'home directory > thindrives'.

• Mount and unmount happens automatically - wait a few seconds.

• If you copy data, wait until the light on the USB stick stops flashing or the progress bar disappear, plus some additional seconds. After that, it's secure to remove the stick.

• If the stick does not appear under directory '~/thindrives', please trigger a remount via menu Applications > System Tools > Repair thindrives (USB Stick , ...) .

• Note: on the Thinstations (they have a an orange startup screen) the USB stick mount is not yet supported

Remote Access: thinlinc@home

By webbrowser

• https://tl.math.uzh.ch

• No sound.
• No local drives
• For touch based devices (Tablets), you'll find a software keyboard on the top of the window,

By native client

• Install the native Client (Linux, Windows, Mac): Download

  • At the moment, there is no native Android, Windows Phone or iOS support. Use the webclient instead.

• Start the native client and connect to:

  tl.math.uzh.ch

  • Be aware, the second character of the servername is a lowercase 'L'!
  • Username / Password: as your I-MATH Account.

• It is possible that you have to accept the hostkey: press 'Continue'

• Disconnect / toggle Full screen: Pressing 'F8' opens a menu, with options for:

  • Disconnect.

  • changing Full Screen.

• Best practice: it's not necessary to log out, just disconnect.

Printing at home

• Choose Thinlocal as Printer
  • It automatically uses your default printer configured on your PC/Laptop at home

Copy files from/to the Thinlinc Session

• This is is very similar as with the USB sticks above.

• Add a mapping of local directories to the ~/thindrives directory inside the thinlinc session.

• Do the mapping before you connect to the session:

  1. Open the 'Thinlinc Client' and choose Options > Local Devices > Drives: Details

  2. Add a new directory and set permissions.

  3. If there are troubles with a mapped directory: inside the thinlinc session, choose the menu Applications > System Tools > Repair thindrives (USB Stick , ...).

Dropbox

You can also use dropbox or switchdrive to copy data to the thinlinc session.

• Dropbox

Keyboard Layout

• If you like to use a keyboard with a different layout than already installed in your office, please contact Support.

• Automatic layout detection: While using the terminals at the institute, the keyboard layout should be detected automatically, regarding the connected keyboard type.

• An efficient and fast solution, to type characters not directly accessible on the keyboard is by using the 'compose key' - please check ComposeKey.

• with new NUC Build (new login Screen) the compose Key may not be working. Please see here to enable the compose Key function - please check enableComposeKey.

• Manual selected keyboard layout:

  • This setting is only valid until the session disconnects.
    • It's boring to change the keyboard layout every time you connect your session - unfortunately, there's no solution at the moment to make the 'manual selected keyboard layout' permanent.

  • Before log in: on the left-bottom-corner of the login screen, you are free to choose another keyboard layout.

  • After log in: If you want to change the keyboard layout on the fly (session is active):

    • Press 'F8'
    • Disable 'Fullscreen'
    • Then you'll see the icon of the 'keyboard layout switcher' in the lower left corner of the screen: click on it to open the 'keyboard layout switcher'
    • Select your favorite layout.
    • If you like, activate 'fullscreen' again by pressing 'F8' again and active 'Fullscreen'.

Audio

General

• Audio redirection only works with the native client - not with the thinlinc browser version.

• If there is no sound at all (verify by playing a youtube video), check the 'Audio redirection' via Applications > Sound & Video > Pulse Audio Volume Control

  • ok: Output: Tunnel to 127.0.0.1:5...

  • broken: Output: Dummy output

• If broken: Disconnet (F8 > Disconnect) Thinlinc Session and log in again. Wait 10 seonds, 'Dummy...' should be replaced by 'Tunnel...'.

• If still 'Dummy...' appears, `Logut' completely (System > Logout) and log in again. Now it should be fine.

Y27

• For using 'headphones', please check if there is a 3.5mm jack at your monitor (varies with the models).

• If you do not find a connector, you can get a USB/Audio converter form Support. Plug the converter in the terminal.

• If you use the preinstalled 'USB Audio Adapter', this has some boring noise on the microphone. We're evaluating new devices.

Private Notebook / Desktop

• Make sure you're using the Native Client (http://tl.math.uzh.ch), not the browser version.

Tablet

• There is no sound redirecting, because there is no native client.

Skype

• Voice, chat and screen sharing are supported.
• Webcams are not supported.

• You can borrow a headset from Support.
