【paramiko更多参考】paramiko模块学习
本机[win7]登录远程Linux服务器
Win7本机IP: 192.168.2.102
远程服务器IP: 192.168.2.105
关于Win7下执行原代码报错问题的解决:
错误现象:TypeError: write() argument must be str, not bytes
问题解决:F:\Django\paramiko-demo\paramiko-master\demos\interactive.py
Linux下paramiko的Demo远程登录执行交互命令:

上传文件到本机Linux服务器:
omc@omc-virtual-machine:~$ cd paramiko_demo/ omc@omc-virtual-machine:~/paramiko_demo$ ll
Linux登录其他的Linux服务器
Linxu本机IP: 192.168.25.110
远程服务器IP: 192.168.25.133

注意:区别于第一次登录,第二次登录可以获取的133服务器的信息,没有了告警

paramiko的interactive改进:

注:记录了文件,但是由点小bug,就是文件会记录下左右移动的操作[此时会转换为二进制的内容]
