%TOC%

---++ Desktop Machines
The LOC has set up a whole practice room full of 22 desktop PC running GNU/Linux Mandriva 2010 32bits.

Each desktop computer in the tutorial room upstairs is ready for you with a 'linux' account (no password).

---+++ Data
Once you start using one workstation, we advise you to keep working with the same computer in order to keep access to your previous data.

%X% Please note that there is __NO BACKUP__ at all performed on desktops, so it is __UP TO YOU__ to take care of your data !!!

Tutorials data are either available in:
   * ==/home/linux/==
   * ==/school/data/==
   * ==/school/tutorials/==

Some files could also be shared through the network in ==/home/nfsShare/==

---+++ Scientific Software
All the school-related software are pre-installed in ==/school/soft/==. Everything should work out of the box, without further configuration !

Here is a list of scientific software available on each desktop:
| *Software* | *Documentation* | *How to launch it* |
| amdlib | http://www.jmmc.fr/data_processing_amber.htm | just type ==emacs -f yorick== in a konsole |
| Aspro | http://www.jmmc.fr/aspro | Do not use the jmmc web site launcher, just type ==aspro== in a konsole <br /> You can also have a preview on the new aspro version using ==Aspro2== |
| IDL |  | just type ==idl== in a konsole |
| LITpro | http://www.jmmc.fr/litpro <br /> you can use the online help in the menu application  | Do not use the jmmc web site launcher, just type ==LITpro== in a konsole |
| MIA | http://mia/ ( this url is only valid onto the school network ) | |
| Oifits Validator | http://www.jmmc.fr/oival  | web app |
| oifitslib | | only ==oifits-merge== is installed |
| python | | |
| scisoft | copy following URL in Firefox : file:///scisoft/doc/ | |
| !SearchCal | http://www.jmmc.fr/searchcal <br /> you can use the online help in the application menu bar | Do not use the jmmc web site launcher, just type ==SearchCal== in a konsole |
| yorick | [[http://server/porquerolles/school/soft/amdlib-3.0b4-bin-Linux-i686/yorick/doc/refs.pdf][Quick guide]], [[http://server/porquerolles/school/soft/amdlib-3.0b4-bin-Linux-i686/yorick/doc/yorick.pdf][Full doc]]| just type ==emacs -f yorick== in a konsole |
| Topcat | The soft gets it own online help | type ==topcat-full== in a konsole |
| Aladin | The soft gets it own online help | type ==Aladin== in a konsole ( %X% case sensitive on the local machines ) |


---+++ Local !WiFi
You can also connect your personnal laptop to the local network using !WiFi:
   * network name (aka SSID) : ==eii==
   * authentication protocol : ==WPA==
   * network password : ==vltischool==

When connected, read school content over *http://server/twiki*

Your laptop should be configured to use DHCP in order to get a valid IP address.

---+++ Web Sites Access
A local web server has be set up and is available on [[http://server.org/twiki/]]. To learn more about TWiki, visit the [[%SYSTEMWEB%.WebHome][TWiki web]].

Here are some reference websites replicated on the local network for your convenience:
   * http://www.vlti.org/home.php.html
   * http://vltischool.obs.ujf-grenoble.fr
   * http://www.european-interferometry.eu
   * http://www.jmmc.fr
   * Part of olbin database available from JMMC web site : http://www.jmmc.fr/bibdb/olbin (some images from NASA are missing, anyway...)
   * http://mia
   * http://mira
   * http://www.eso.org/

%X% Because the network is standalone (i.e not connected to Internet), those website mirrors may not be complete (external references missing, pictures, ...).

---+++ Internet Connection
There is no free Internet connection provided by IGESA, so desktop computers cannot access the Internet.

But 3 paid connection tokens (one person at a given time) can be shared (!) amongst participants using WiFi and your own laptop:
The expired ones have been deleted to keep the list simple.
| SSID | login | password ||
| ==orange== | ==VY0GK06== | ==R5K178738== | %X% Please do not forget to close the session! Somebody forgot to log out on Sunday?|
| ==orange== | ==VM8093O== | ==WKHSCG721== | %X% Please do not forget to close the session |


Some hotels downtown also provide free !WiFi access you can wardrive to use ;)

---++ Network
All desktop PC are networked and connected to a central server for administration and data distribution purpose.

---+++ Workstation Map
The host names of workstations are ==DC-7800-nn== for IP address ==192.168.0.nn==, where ==nn== is written on each workstation sticker. %BR%
Here is a map of the tutorial room seen from the server desktop at the back near workstation 01 while looking at the front of the room:
<verbatim>
              ------
              | 01 |

</verbatim>
---+++ Printing
A [[http://192.168.0.249][HP Color LaserJet 2605dn]] network printer is available on ==192.168.0.249==.

---++ Server
A central server have been prepared and installed by Sylvain and Guillaume, mainly to distribute data and software and provide the following services:
   * NFS server, dynamically distributing data stored on the server (in ==/mariotti/home/data/porquerolles/nfsShare/==) to each workstation (accessible in ==/home/nfsShare/==);
   * HTTP server, accessible from any workstation or laptop on the ==eii== !WiFi by pointing your favorite web browser to [[http://server.org]];
   * RPM database server for software installation;

The school-related data on the server are in ==/mariotti/home/data/porquerolles/==. %BR%
The ==/mariotti/home/data/porquerolles/school/== server subdirectory is the source of all data replicated on each workstation. %BR%
Teachers can put some files in it and distribute them to all workstations at once using a single command (as root) : ==rsyncFromMacminiToClients.sh==

Other commands can also be run (as root) on all the clients at once using PSSH : ==pssh -P -t -1 -h /root/hostList.txt "urpmi --auto mpmath"==

The server IP address is ==192.168.0.250==.

After a server reboot (electricity shortage, ...), you should enter the following commands (as root):
<verbatim>
cd /root/porquerolles/admin
./serverSetup.sh
</verbatim>

<verbatim>
[root@server admin]# more /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
IPADDR=192.168.0.250
NETMASK=255.255.255.0

METRIC=10
MII_NOT_SUPPORTED=yes
