SSH Cela ne fonctionne pas pour mon serveur

Supposons que mon serveur ait "mien" ip. Client - Ceci est une voiture en cours d'exécution Linux (debian) de IP 192.168.15.120. J'ai essayé d'une autre machine (Windows) Dans le même sous-réseau avec ip 192.168.15.106. "ma" - Ceci est le serveur sur Internet avec ip 195.xxx.xxx.xxx (nécessairement en dehors du réseau local). Machines. Windows peut me connecter à moi ssh, et moi (client Linux) - ne pas. Quand j'ai changé de port sur mon serveur ssh sur 7822, Mon client pourrait utiliser ssh pour lui. Il semble que quelque chose avec le port 22 Sur mon client n'est pas le cas. Quel est ton opinion? Comment puis-je suivre le problème et le trouver?

Rafraîchir:

Après le lancement ssh -v my J'ai eu le résultat suivant:
