Alterar o log do PuTTY para "pacotes SSH" + Alguma coisa útil no log do servidor?

Provavelmente, você está lidando com o servidor faltando alguns recursos ( SSH-2.0-ROSSSH) e o Putty não é capaz de lidar com esta mensagem. Mas realmente, o que você está tentando alcançar? Parece bem selvagem.

@MartinPrikryl eu adicionei novas informações dos meus logs de pacotes ssh, espero que ajude #

@Kibbz, pode ser o seu caso foi o mesmo que eu descrevi na minha resposta abaixo? Vejo que ajudou muitas pessoas - você pode conferir e selecionar a resposta certa?

Para mim, a chave era que o algoritmo de troca de chaves "Diffie-Hellman group exchange" não foi implementado no servidor (consulte Conexão > SSH > KEX ).

Mover esse algoritmo de troca de chaves para o final da lista e criar o algoritmo "Diffie-Hellman group 14" resolveu o problema para mim.

Eu recebi um erro semelhante em 0,63 ... atualizar para 0,67 fez com que ele desaparecesse.

@ kibbz: você pode fazer esta resposta como aceita, pois isso resolve a questão do desejo.
