Dicas para solução de problemas de SSH em software proprietário

Estou tendo um problema ao estabelecer um canal com uma peça de hardware que compramos. Eu posso SSH no sistema operacional VXworks usando tanto o Putty (no Windows) quanto o CLI do Ubuntu, no entanto, quando eu envio comandos para o hardware usando Ruby ou Python, recebo "conexão fechada pelo host remoto".

Eu fiz o seguinte:

  1. Tentei diferentes linguagens de programação com diferentes implementações em diferentes sistemas operacionais
  2. Tentei diferentes versões do Ruby e Net :: SSH incluindo o alpha 4.0
  3. Acesso permitido à porta 22 ao hardware, no hardware
  4. Adicionando um tempo limite
  5. Especificando chaves Kex específicas
  6. Estreitando o KEXIT (acredito que seja chamado)
  7. Entrou em contato com os engenheiros. Eles não acreditam que está no seu fim, no entanto, eles estão aumentando a cadeia
  8. Script Python dentro do secureCRT, que realmente funcionou.

Quais são as próximas coisas que devo verificar? Eu estou sem ideias.

Um engenheiro disse:

"The scripts do need to have buffering between the commands. I've used securecrt for a scripting."

Aqui está o script secureCRT que me permitiu conectar à unidade. Não estou totalmente confiante de que isso seja relevante: 

host = "x.x.x.x"
user = "admin"

def main():
    # Prompt for a password instead of embedding it in a script...
    #
    passwd = crt.Dialog.Prompt("Enter password for " + host, "Login", "", True)

    # Build a command-line string to pass to the Connect method.
    cmd = "/SSH2 /L %s /PASSWORD %s /C 3DES /M MD5 %s" % (user, passwd, host)
    crt.Session.Connect(cmd)


main()

Aqui está o log do sistema VXworks:
