Perché la mia connessione SSH è in ritardo durante la digitazione?

4

Recentemente ho notato un piccolo fastidio con le connessioni SSH da macOS Sierra. Di recente vorrei dire la scorsa settimana o forse due.

Mi sono collegato a un server tramite SSH e tutto è stato connesso abbastanza velocemente come mi sarei aspettato, quindi almeno la metà delle volte che inizio a digitare, non verrà visualizzato nulla per circa 2-5 secondi . Ho provato questo sulla mia macchina Linux ed entrambi i server sono stati collegati bene senza alcun ritardo - quindi escludo problemi di rete, velocità di connessione a Internet, ecc.

Ho cercato su google dove i suggerimenti erano più sulla connessione iniziale e non sul lag quando connesso.

Attualmente a perdita completa, potrebbe fare qualche consiglio da qui.

Aggiornamento Così ho deciso di riavviare il mio MacBook e tutto sembra tornato normale, i miei pensieri sono che a un certo punto chiudendo il Mac o chiudendo lo schermo durante la modalità sospensione un servizio non si riavvia correttamente ?

Lo terrò d'occhio, primo segno di problemi entrerò nella syslog e pubblicheremo ulteriori cose in questo caso qualcuno potrebbe aiutare a risolvere questo problema (preferibilmente mi piacerebbe solo riavviare solo per gli aggiornamenti del kernel o quando app Store lo richiede)

Non sei solo con questo problema. L'ho sperimentato molto anch'io. Anche se non sono esperto e non ho molte prove, credo che il problema sia dovuto al modo in cui è stato programmato ssh. Uno strumento molto simile, mosh , fa la maggior parte delle cose che ssh fa mentre elimina il lag e aggiunge altre funzionalità. Tuttavia, molto probabilmente dovrai installarlo sia sul PC che sul server affinché funzioni. Spero che questo ti possa aiutare.
