Python使用paramiko库远程安全连接SSH

• paramiko实例(账号密码登录执行命令)

#!/usr/bin/python

#ssh
import paramiko
import sys,os

host='127.0.0.1'
user = 'whl'
password = '123456'

s = paramiko.SSHClient() # 绑定实例
s.load_system_host_keys() # 加载本地HOST主机文件
s.set_missing_host_key_policy(paramiko.AutoAddPolicy()) # 允许连接不在know_hosts文件中的主机
s.connect(host,22,user,password,timeout=5) # 连接远程主机
while True:
cmd=raw_input('cmd:')
stdin,stdout,stderr = s.exec_command(cmd) # 执行命令
cmd_result = stdout.read(),stderr.read() # 读取命令结果
for line in cmd_result:
print line

• paramiko实例(传送文件)

#!/usr/bin/evn python
import os
import paramiko
host='127.0.0.1'
port=22
user = 'whl'
password = '123456'
ssh=paramiko.Transport((host,port))
privatekeyfile = os.path.expanduser('~/.ssh/id_rsa')
mykey = paramiko.RSAKey.from_private_key_file( os.path.expanduser('~/.ssh/id_rsa')) # 加载key 不使用key可不加
ssh.connect(username=username,password=password) # 连接远程主机
# 使用key把 password=password 换成 pkey=mykey
sftp=paramiko.SFTPClient.from_transport(ssh) # SFTP使用Transport通道
sftp.get('/etc/passwd','pwd1') # 下载 两端都要指定文件名
sftp.put('pwd','/tmp/pwd') # 上传
sftp.close()
ssh.close()

• paramiko实例(密钥执行命令)

#!/usr/bin/python
#ssh
import paramiko
import sys,os
host='127.0.0.1'
user = 'whl'
s = paramiko.SSHClient()
s.load_system_host_keys()
s.set_missing_host_key_policy(paramiko.AutoAddPolicy())
privatekeyfile = os.path.expanduser('~/.ssh/id_rsa') # 定义key路径
mykey = paramiko.RSAKey.from_private_key_file(privatekeyfile)
# mykey=paramiko.DSSKey.from_private_key_file(privatekeyfile,password='061128') # DSSKey方式 password是key的密码
s.connect(host,22,user,pkey=mykey,timeout=5)
cmd=raw_input('cmd:')
stdin,stdout,stderr = s.exec_command(cmd)
cmd_result = stdout.read(),stderr.read()
for line in cmd_result:
print line,
s.close()
