-    * From a Windows computer:
-      * Text only: use [[other:win10apps#putty_pageant|Putty]]. Putty allows you to open text terminals on remote computers
-      * Text **and graphics**: you need to [[https://wiki.lsce.ipsl.fr/pmip3/doku.php/other:win10wsl#using_an_x_server|install an X server]] on your computer in order to display the graphics
-  - You can access all LSCE disks from //ssh1//, but there is only a limited number of programs that you can run, so you have to go from //ssh1// to //obelix// or //irene// with one of the ''ssh'' commands below:
-    * ''ssh obelix''
-    * ''ssh your_tgcc_login@curie-ccrt.ccc.cea.fr''
-  - It's possible to use only one line to to both ssh commands
-    * obelix: ''ssh -A -X your_lsce_login@ssh1.lsce.ipsl.fr -t ssh -A obelix''
-    * TGCC: ''ssh -A -X your_lsce_login@ssh1.lsce.ipsl.fr -t ssh -A your_tgcc_login@curie-ccrt.ccc.cea.fr''
-  - You can define an alias in order to connect more easily to the machines:
-    * //tcsh// users: add the following line to your ''~/.cshrc'' configuration file\\ ''alias sobelix 'ssh -A -X your_lsce_login@ssh1.lsce.ipsl.fr -t ssh -A obelix'''
-    * //bash// users: add the following line to your ''~/.bashrc'' configuration file\\ ''alias sobelix='ssh -A -X your_lsce_login@ssh1.lsce.ipsl.fr -t ssh -A obelix'''
-  - You should create and configure an //ssh key//, if you don't want to type your password each time you use ssh or scp
-  - If you want more information about ''ssh''

-==== Copying files to/from LSCE ====
-If you need to **transfer** files to/from LSCE, use ''scp'' (on Linux and Windows 10), or a graphical scp client such as [[https://wiki.lsce.ipsl.fr/pmip3/doku.php/other:win10apps#winscp|WinSCP]] (on Windows) between your computer and ''ssh1.lsce.ipsl.fr''
-  * Example:
-    * Sending **one file** from a Linux/Windows10/Mac computer to your //scratch// directory at LSCE:\\ ''scp -p file_on_your_computer_outside_lsce your_lsce_login@ssh1.lsce.ipsl.fr:/home/scratch01/your_lsce_login/''
-    * Sending recursively **a full directory**:\\ ''scp -pr directory_on_your_computer_outside_lsce your_lsce_login@ssh1.lsce.ipsl.fr:/home/scratch01/your_lsce_login/''
