SSH Connection refused

[Shikyo]

Bonjour / Bonsoir.

J'ai un petit problem avec mon serveur ssh. J'arrive tres bien a me connecter via l'ip local, mais impossible de me connecter depuis mon ip publique.

J'ai comme message d'erreur: "ssh: connect to host XXX.XXX.XXX.XXX port YYYYY: Connection refused".

J'ai ouvert le port en input et output et mon netsat me dit que j'ai bien le port en LISTEN.

Le client est sous ubuntu et le server sous kali.

Merci d'avance pour ma ytude

Bonsoir,

as-tu regardé les logs pour avoir un peu plus de détails ? (/var/log/auth.log).

Peux-tu également poster ton fichier de configuration de ton sshd ?

Bonne soirée...
