Connection to front machines
Under construction …
To connect to PSMN cluster, you need to use SSH (Ssecure SHell). The easiest way is to use the following command:
For your FIRST CONNECTION,
please follow these instructions to generate your PSMN SSH key pair.
please follow these instructions to generate your PSMN SSH key pair.
- From a Linux or a MacOS X computer, open a terminal and type:
ssh votrelogin@allo-psmn.ens-lyon.fr
- From a Windows computer, refer to PuTTY documentation.
Once connected to allo-psmn, you have access to your home-directory and therefore all your files.
allo-psmn is a connection server, it only allows you to access and to transfer your files and that's all.
Its only purpose is to connect to the PSMN's network to access front machines.
To work on PSMN cluster, you need to connect from
allo-psmn to one of the compilation server (front machines).
To do so, type the following comman on allo-psmn (For MAcOSX user replace -X BY -Y):
ssh -X nom_serveur_de_compilation
with nom_serveur_de_compilation is the name of one of the compilation server.
Vous pouvez simplifier votre usage des commandes SSH en utilisant un jeu de clefs, un agent SSH et une configuration adaptée (voir le paragraphe suivant).
Si vous disposez déjà d'un jeu de clef SSH sans mot de passe, copiez les clefs publiques (id_?sa.pub) dans le fichier ~/.ssh/authorized_keys.
Si vous disposez aussi d'un jeu de clefs SSH personnel (avec passphrase), vous pouvez ajouter votre clef publique (id_?sa.pub) au fichier ~/.ssh/authorized_keys.
Connection from outside of the ENS
Please follow this documentation.
Use SSH key and SSH agent
To automatize your connections and your copies, you need to use a pair of SSH keys and a SSH agent, see documentation.
Vous y trouverez :
- un rappel des commandes pour générer un jeu de clefs SSH
- un rappel des commandes pour démarrer un agent et lui fournir une clef
Use (and automatize) multi-hop SSH
To automatize even more your connections and your copies, you can use multi-hop SSH, by following the documentation.
