The Linux guest is just a regular Linux machine! We have detailed below only a few technical details

Depending on what you need to do:

• run a single command with the root access rights
  sudo command
• become root in a terminal
  sudo su -
• use the root password when a program asks for it. Be sure the programs has legitimate reasons to ask for the root password!
• login as root

• login with the root account
• change the system and root account language to English, if it's not already the case:
  • Menu ⇒ Administration ⇒ Langue ⇒ English (USA)
  • Menu ⇒ Préférences ⇒ Langues ⇒ English, United States
  • reboot
• create the new account:
  Menu ⇒ Administration ⇒ Users and Groups (the second one!)
  • Add User: Warning, make sure the home directory will be created in /homel and not the default /home
• add the new johndoe account to the people who can use the sudo command:
  echo -e 'johndoe\tALL=(ALL)\tALL' > /etc/sudoers.d/johndoe

Note: you have to be root to install a program on the command line with yum!

The following steps can be used to copy the UV-CDAT installed on asterix to a desktop/laptop with a similar linux installation

• Create the top directory where the UV-CDAT versions will be installed (make sure there is enough space available, a few Gb…):
  mkdir /homel/cdat
chown jypeter:lsce /homel/cdat
• Create a link from where UV-CDAT thinks it is installed, to where it is actually installed (just in case some paths are hard-coded, you never know…):
  mkdir -p /usr/local/install
cd /usr/local/install
ln -s /homel/cdat cdat
• Use rsync to send the UV-CDAT binaries from a machine where it is installed, to the new machine:
  rsync -avzW –delete /usr/local/install/cdat/ jypeter@lsceNNNN:/homel/cdat/
• Use the following to initialize UV-CDAT:
  • Version 1.5
    • *sh: source /usr/local/install/cdat/versions/cdat_install_uv-1.5.1_x86_64_gcc4_VB_10/bin/setup_runtime.sh
    • tcsh: source /usr/local/install/cdat/versions/cdat_install_uv-1.5.1_x86_64_gcc4_VB_10/bin/setup_runtime.csh
  • Version 2.1.0
    • *sh: source /usr/local/install/cdat/versions/cdat_install_uv-2.1.0_x86_64_gcc4_VB_13/bin/setup_runtime.sh
    • tcsh: source /usr/local/install/cdat/versions/cdat_install_uv-2.1.0_x86_64_gcc4_VB_13/bin/setup_runtime.csh
