Résumé
Je veux copier des fichiers entre 2 serveurs distants en utilisant Rsync et SSH. Le moyen que j'ai trouvé pour le faire est de créer un tunnel SSH, mais j'ai essayé avec plusieurs exemples et aucun d'entre eux n'a fonctionné.
Détails
- J'ai 3 machines : 1 ordinateur local et 2 serveurs distants
- Je peux me connecter en SSH aux deux serveurs distants en utilisant ma clé RSA locale.
- Les 2 serveurs distants ne peuvent pas se parler entre eux. Le serveur distant n°1 n'a pas accès au serveur distant n°2 et vice versa.
- Je peux utiliser Rsync sur les deux serveurs distants individuellement.
Ce que j'ai essayé
ssh -vvv -A \
-l user_remote1 \
-R localhost:50000:remote2:22 user_remote1@remote1 \
'rsync -e \
"ssh -A -o StrictHostKeyChecking=no \
-o UserKnownHostsFile=/dev/null \
-o GlobalKnownHostsFile=/dev/null \
-p 50000" \
-var /home/user_remote1/test.txt user_remote2@localhost:/home/user_remote2'Sortie de cette commande
OpenSSH_8.1p1, LibreSSL 2.7.3

Y a-t-il quelque chose d'incorrect dans la commande ou peut-être ai-je besoin d'une configuration personnalisée dans les serveurs ? Tout commentaire sera utile. Merci.
