General documentation on using the training laptops can be found on the intranet.

XX – laptop number Switch on the laptop and log in as: Username: trainXXuser Password: ******** (available from your trainer, JohanCarlin, OlafHauk, or IT)

For many classes, VNC sessions should already be running for each account. If this is the case: Connect to it using a VNC viewer (e.g. TurboVNC is preferred but UltraVNC will do, too). The server you need to connect to will be loginXX, if XX > 10, or XX+10 if XX<11. e.g. train01linux will have a vncserver on login11, train12linux will connect to login12. If connecting to the login gpu nodes, 01-04 use login-gpu02, 05-08 use login-gpu03, 09-12 use login-gpu04, and 13-15 use login-gpu05 NB both schemes may be replaced soon with a simpler one. (14/02/18) The VNC display number (sometimes called desktop number) should be 70+XX. e.g for train02 - login12:52, for train13 - login13:63 Password: ******** (available from your trainer, Tibor, Olaf or IT)

* Use PuTTY to connect to one of the login nodes. You can use 'login' as the host name, or use the name of a specific login node (currently login11 - login26): Host: On some of the laptops, gateway (gate.mrc-cbu.cam.ac.uk) may be set as default connection. Make sure, that you do not use it, because it is slower! Username: trainXXlinux Password: ******** To check for currently running servers, type: showallvncs If a vnc server is not already running, you can start one using: vncstart Connect as above, using the login node and display provided by the vncserver.

The preferred method for configuring the environment for the training accounts is the vnc_setup.py script (/imaging/local/linux/config/bin/vnc_setup.py). ] [-g] [-s] kill | clean | purge | passwd | startvnc | setupvnc | showvncs | synch This script must be run with root privilege directly or via sudo. ]]> given with -d ]]> Source directory for synch. Only valid with synch, if absent will attemtp to find a file from /imaging/local/linux/config/train.login]]>The materials specific with -d <> must be world-readable and -writable, e.g. located in /imaging/training/materials. The script needs to be run as root or via sudo. OlafHauk, or IT have appropriate permissions. The usual method of resetting all the accounts is (assuming sudo is needed and the script is in your PATH: synch]]>Note: The to-be-synched directory should only contain letters and numbers. This should empty the training accounts' imaging spaces, kill old vncservers, start new ones, and rsync the source directory (which will recursively include subdirectories)into the imaging spaces.

set in /imaging/local/linux/config/train.chsrc cdw: change directory for Workshop folder of the current user (/imaging/trainXXlinux/Workshop) matlab: Launch Matlab R2012b (required for aa) vncstart: Open the designated VNC server with the optimal resolution (N.B. vncserver is shadowed by an alias with the same name pointing to showallvncs to avoid "unwanted" VNC sessions. Would you even need to use vncserver, you can call it with its full path: /hpc-software/bin/vncserver) vnckill: Close the designated VNC server

Here, some more specific instructions about how to set up them for a hands-on session can be found:

XX – laptop number Switch on the laptop and log in as: Username: trainXXuser Password: ******** (available from your trainer, JohanCarlin, OlafHauk, or IT) Use PuTTY to connect to one of the login nodes. You can use 'login' as the host name, or use the name of a specific login node (login01 to login22): Host: On some of the laptops, gateway (gate.mrc-cbu.cam.ac.uk) may be set as default connection. Make sure, that you do not use it, because it is slower! Username: trainXXlinux Password: ******** (available from your trainer, e.g. JohanCarlin, OlafHauk or IT) It may take a while to synchronise Materials (see below) A VNC server should already be running for the training account. To check, type: showallvncs The output should show you that a vncserver is running on the login node that matches the number of username, e.g. train01linux will have a vncserver on login01, etc. The vnc desktop number should be 51 in all cases. If a vnc server is not already running, you can start one using: vncstart Once your VNC server is running, connect to it using a VNC viewer (e.g. TurboVNC is preferred but UltraVNC will do, too). The server you need to connect to will be running on the login node that matches the number in your username, e.g. train01linux will have a vncserver on login01, etc. The vnc desktop number should be 51 in all cases. VNC server: loginXX:51 (e.g. login01:51 for train01 on login01, login08:51 for train08 on login08) Password: ******** (available from your trainer, Tibor, Olaf or IT)

/imaging/local/linux/config/train.login (executed during login via PuTTY) /imaging/local/linux/config/train.chsrc (executed during opening a shell) serve as central setting for all training account. If you want to add some settings (e.g. configuration for programs), you can do it here.

set in /imaging/local/linux/config/train.chsrc cdw: change directory for Workshop folder of the current user (/imaging/trainXXlinux/Workshop) matlab: Launch Matlab R2012b (required for aa) vncstart: Open the designated VNC server with the optimal resolution (N.B. vncserver is shadowed by an alias with the same name pointing to showallvncs to avoid "unwanted" VNC sessions. Would you even need to use vncserver, you can call it with its full path: /hpc-software/bin/vncserver) vnckill: Close the designated VNC server

set in /imaging/local/linux/config/train.login The Material folder (/imaging/trainXXlinux/Workshop/Material) is synchronized automatically with any folder of your choosing (I recommend using folder name Material to be consistent). The SOURCE folder can be set in /imaging/local/linux/config/train.login (line 1).

You can synchronise your material from any VNC session (i.e. you don't need the physical laptop). ssh trainXXlinux@loginXX will start the synchronisation (if enabled in train.login, see above).
