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()
