-===== Accessing the LSCE servers from outside the LSCE ===== +===== Getting help, when using the IPSL Mesocenter =====
- +
-The only way to access the LSCE servers from outside LSCE is to connect first to the **ssh1.lsce.ipsl.fr** gateway server. +
- +
-==== Interactive access ==== +
- +
-  - Send a mail to //help-lsce//, and request an access to the //ssh1// server +
-  - Use ''ssh'' to **connect** to //ssh1// +
-    * From a Linux/mac desktop: ''ssh -A -X your_lsce_login@ssh1.lsce.ipsl.fr'' +
-    * From a Windows desktop: +
-      * Text only: use [[other:win7apps#putty|Putty]] +
-      * Text & graphics. This is more complex to set up, and you need to use one of the options below: +
-        * use [[other:win7apps#vcxsrv_windows_x_server|VcXsrv]] +
-        * use [[other:win7apps#cygwin-x|cygwin/X]] +
-        * use [[other:index#virtualbox_notes|VirtualBox]] +
-  - 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 //curie// 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'' +
-    * Linux users: http://ciclad-web.ipsl.jussieu.fr/data/documents/ssh-utilisateurs-unix.pdf +
-    * Windows users: http://ciclad-web.ipsl.jussieu.fr/data/documents/ssh_putty_v2_2011-1.pdf +
- +
-==== Copying files to/from LSCE ==== +
- +
-If you need to **transfer** files to/from LSCE, use ''scp'' (on Linux), or an scp client such as [[other:win7apps#winscp|WinSCP]] (on Windows) between your computer and ''ssh1.lsce.ipsl.fr'' +
- +
-  * Example from a Linux/mac desktop: ''scp -p file_outside_lsce your_lsce_login@ssh1.lsce.ipsl.fr:/home/scratch01/your_lsce_login/''+
