SSH-2.0-ROSSSH) i Putty nie jest w stanie obsłużyć tej wiadomości. Ale tak naprawdę, co próbujesz osiągnąć? Wygląda całkiem dziko.Odpowiedzi:
Dla mnie kluczem było to, że algorytm wymiany kluczy „Wymiana grup Diffie-Hellmana” nie został zaimplementowany na serwerze (patrz Połączenie > SSH > KEX ).
Przeniesienie tego algorytmu wymiany kluczy na dół listy i uczynienie algorytmu „Diffie-Hellman group 14” rozwiązało dla mnie problem.

Mam podobny błąd na 0.63 ... aktualizacja do 0.67 sprawiła, że zniknął.
