Tout d'abord, j'ai cherché pendant une journée entière et bien qu'il y ait similaire problèmes autour de moi, je ne trouve personne ayant ce problème exact.
Mon hackintosh fonctionnant sous 10.12.3 a OpenSSH installé via homebrew. Il se bloque exactement à la même ligne "rekey", quel que soit le serveur auquel je me connecte, et je ne sais pas pourquoi.
(note : le résultat attendu de l'opération ci-dessous devrait se terminer par
Permission refusée (publickey).
parce que je n'ai pas installé le certificat, mais j'utilise seulement git@github.com pour tester. Mais il ne va même pas jusque là, et c'est là le problème. Ma boîte de serveur domestique fonctionnant sous ubuntu donne le même point de suspension).

D'autres ordinateurs (par exemple Macbook Air) avec le ssh natif de Mac n'ont aucun problème. C'est seulement le hackintosh. Une idée sur la façon dont je peux résoudre le problème ensuite ?
Merci d'avance.
Note : Je peux accéder au hackintosh sans problème, mais pas depuis celui-ci.
