Récemment, j'ai remarqué un petit désagrément avec les connexions SSH depuis MacOS Sierra. Par récent, je dirais la semaine dernière ou peut-être deux.
Je me suis connecté à un serveur via SSH et tout s'est connecté assez rapidement comme je m'y attendais, mais au moins la moitié du temps, lorsque je commence à taper, rien ne s'affiche pendant environ 2-5 secondes . J'ai essayé sur ma machine Linux et les deux serveurs se sont connectés sans aucun décalage. J'ai donc exclu les problèmes de réseau, de vitesse de connexion Internet, etc.
J'ai cherché sur Google où les suggestions concernaient plutôt la connexion initiale et non le décalage une fois connecté.
Je suis actuellement dans une impasse totale et j'aurais besoin de conseils ici.
Mise à jour J'ai donc décidé de redémarrer mon macBook et tout semble redevenir normal. Je pense qu'à un moment donné, lorsque l'on verrouille le mac ou que l'on ferme l'écran en mode suspension, un service ne redémarre pas correctement ?
Je vais garder un oeil dessus, au premier signe de problème, j'irai dans la salle des fêtes. syslog et poster d'autres choses ici au cas où quelqu'un pourrait aider à résoudre ce problème (idéalement, je voudrais seulement redémarrer pour les mises à jour du noyau ou lorsque l'App Store le demande).
