Créer un fichier ~/.ssh/config pour définir ….
Le fichier config contient un ensemble règles définies par des paires clé-valeur :
<code> # syntaxe 1 config1 value1 value2 # syntaxe 2 équivalente config1=value1 value2
Les clés les plus utilisées :
| clé | valeur |
| Host | Restricts the following declarations (up to the next Host or Match keyword) to be only for those hosts that match one of the patterns given after the keyword. If more than one pattern is provided, they should be separated by whitespace. |
| HostName | Specifies the real host name to log into. |
| User | Specifies the user to log in as. This can be useful when a different user name is used on different machines. This saves the trouble of having to remember to give the user name on the command line. |
| IdentityFile | Specifies a file from which the user's DSA, ECDSA, Ed25519 or RSA authentication identity is read. The default is ~/.ssh/id_dsa, ~/.ssh/id_ecdsa, ~/.ssh/id_ed25519 and ~/.ssh/id_rsa. |
| LocalForward | Specifies that a TCP port on the local machine be forwarded over the secure channel to the specified host and port from the remote machine. |
Exemple :
# Contexte ~/.ssh/config
Host nas01
HostName 192.168.1.100
User root
IdentityFile ~/.ssh/nas01.key
# Utilisation
ssh nas01
# remplace ssh root@192.168.1.100 avec la clé nas01.key
/etc/ssh/ssh_config : This files set the default configuration for all users of OpenSSH clients on that desktop/laptop and it must be readable by all users on the system.
