Astuces SSH

Tunelling

Parce que je m'en rapelle jamais (tête de linote):

$ ssh -f hote -L local:lolnet.org:destination -N

.ssh/config

(merci gaston !)

La directive suivante dans .ssh/config permet de sauter d'hôte en hôte séparés par des "+" :

Host *+*
        ProxyCommand ssh $(echo %h | sed
's/+[^+]*$//;s/\([^+%%]*\)%%\([^+]*\)$/\2 -l \1/;s/:/ -p /')
PATH=.:\$PATH nc -w1 $(echo %h | sed 's/^.*+//;/:/!s/$/ %p/;s/:/ /')

On peut donc spécifier des "sauts" ssh du style:

ssh root@91.25.25.25+192.168.1.1

Ensuite on peut essayer de rajouter:

Host <label_pour_mon_serveur_privé>
    user <monuser(root)>
    IdentityFile  <chemin vers ma clé ssh pour le serveur publique>
    hostname ip_serveur_publique+ip_serveur_privé
