Python Paramiko/SSHエラー

Question

私はPythonの初心者で、SSHの使い方を学んでいます。エラーの原因を特定するのに助けてくれる人がいますか？基本的には、その出力は、デバッグ、コード

class Ssh: 

def connect(self, host, user, password): 
    ssh = paramiko.SSHClient() 
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) 
    ssh.connect(host, username = user, password = password) 
    self.node = ssh 

def cmd(self,command): 
    stdin, stdout, stderr = self.node.exec_command(command) 
    return stdout.read() 

node = Ssh() 
node.connect(host,user,pwd) 
ver = node.cmd('show version') 
print(ver) 

は

印刷/ Unixのボックスからssh経由でデバイスに接続して、簡単な「は、show version」コマンドを実行し、返却しようとしています

Answer 1

私は別のベンダーによって提供されている別のデバイスでこれを試してみました。この特定のベンダーがparamiko configでいくつかの調整が必要なようです。
