Je peux me connecter via SSH en utilisant l'authentification par clé sur SERVER1 et SERVER2. Cependant, je ne peux pas copier de fichiers entre les deux serveurs. Pourquoi? Comment puis-je copier entre eux? (les données que je dois copier sont plus grandes que le disque dur de mon ordinateur portable)
Mon ordinateur portable fonctionne sous Ubuntu 10.04 LTS et les deux serveurs sont AIX 5300-10-02-0943. Mon ~/.ssh/known_hosts
fichier sur mon carnet contient les clés publiques de ces deux serveurs. J'utilise tsocks
car je dois utiliser un tunnel SSH pour atteindre ces deux serveurs. Les deux serveurs peuvent se cingler.
