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()
