Estou tentando usar o servidor/cliente ssh integrado no Windows10:
o ssh abre perfeitamente quando executo ssh localhostou ssh user@local_IP_address(estou usando autenticação baseada em chave)
Agora encaminhei a porta 22 no meu roteador e estou tentando acessar o ssh por meio de um IP externo -
ssh user@remote_IP_address
eu recebo
erro de protocolo kex: tipo 30 seq 1
quando eu corro
ssh user@remote_IP_address -vv
eu recebo
OpenSSH_for_Windows_7.6p1, LibreSSL 2.6.4

Eu tentei usar o putty para conectar e recebo um erro semelhante mesmo quando reorganizo os algoritmos kex para que Diffie-Hellman group1 seja o último
a mensagem de erro diz
Pacote inesperado recebido ao esperar resposta ECDH, digite 30(SSH2_MSG_KEX_ECDH_INIT)
Responder1
Existem casos raros, principalmente com máquinas virtuais, quando o putty como uma interface de conexão SSH falha devido aos fundamentos de segurança da Microsoft ou ao firewall do Windows para ter uma solução que deve ser configurada, porém em relação à string de erro de tipo: Erro de protocolo Kex: tipo 30 seq 1 O erro supostamente é definido pela troca de grupo Diffie-Hellman KEX é obsoleto, portanto, deve ser atualizado no cliente e no servidor para uso SSH, além disso, alguns terminais PuTTY, pois o software deve ser atualizado.
