Question

尝试构建一个自包含的python脚本，通过paramiko连接到服务器，私钥文件和known_hosts存储在本地目录中。它连接但它一直出错：

paramiko.transport: TypeError: long() argument must be a string or a number, not 'NoneType'

我在文档或代码中找不到任何关于此处发生的事情。

client = paramiko.SSHClient()
paramiko.util.log_to_file('paramiko.log')
client.load_system_host_keys('known_hosts')
client.set_missing_host_key_policy(paramiko.WarningPolicy())
client.get_host_keys().add(hostname, 'ssh-rsa', key)
client.connect(hostname, username='root', pkey=key)
print '\tconnected'
self.stdin, self.stdout, self.stderr = client.exec_command('/usr/local/sbin/comd')

client.close()

请检查pkey是否确实包含您的私钥。如果没有，请加载

pkey = paramiko.RSAKey.from_private_key_file("priv.key")

另请注意＆＃34; host_keys＆＃34;包含远程主机的公钥列表。您的代码实际上将您的私钥推送到＆＃34; known_hosts＆＃34;用于主机密钥验证的db。请删除此行或在那里添加远程主机pubkey。

client.get_host_keys().add(hostname, 'ssh-rsa', peer_pubkey)

paramiko中的错误：paramiko.transport：TypeError：long（）参数必须是字符串或数字，而不是＆＃39; NoneType＆＃39;
