SSH peu réactif...

Bonjour à tous,

J'ai un petit soucis concernant openssh. J'ai quelques petits ralentissements assez pénibles lorsque je me connecte par SSH à mon serveur distant.

Il ne me semble pas que le problème vienne du serveur vu que je n'ai aucun de ces problèmes quand je me connecte depuis Windows, WSL ou même termux sur android.

J'ai quand même désactivé DNS sur mon serveur et d'autre recommandations que j'ai trouvé en cherchant, j'ai même essayé plusieurs terminaux; mais rien y fait, j'ai toujours ces petites saccades agaçantes quand je tape des commandes ou que je navigue dans mes dossier avec nnn ou ranger par exemple.

Si quelqu'un pouvait m'aider. Merci beaucoup.

Re : SSH peu réactif...

Utilise ssh avec l’option -v afin de voir ce qu'il se passe.

Oui, le plus embêtant c'est que je n'ai pas de message d'erreur.

Re : SSH peu réactif...

Tu as aussi l'option -C ( compression) qui permet une communication plus fluide. Elle est peut être insérée d'office sur tes autres applis
