Python实现SSH远程登陆，并执行远程命令

主要使用paramiko 模块

import paramiko  def sshclient_execmd(hostname, port, username, password, execmd):      paramiko.util.log_to_file("paramiko.log")      s = paramiko.SSHClient()      s.set_missing_host_key_policy(paramiko.AutoAddPolicy())      s.connect(hostname=hostname, port=port, username=username, password=password)      stdin, stdout, stderr = s.exec_command (execmd)      stdin.write("Y")  # Generally speaking, the first connection, need a simple interaction.      print stdout.read()      s.close()  def main():      hostname = '10.***.***.**'      port = 22      username = 'root'      password = '******'      execmd = "free"      sshclient_execmd(hostname, port, username, password, execmd)  if __name__ == "__main__":      main()
