| - | ===== Accessing the LSCE servers from outside the LSCE ===== | ||
| - | |||
| - | 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 terminal on a Linux/Windows10/Mac computer: ''ssh -A -X your_lsce_login@ssh1.lsce.ipsl.fr'' | ||
| - | * 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'' | ||
| - | * 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 and Windows 10), or a graphical scp client such as [[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/'' | ||
