本機[win7]登陸遠程Linux服務器sql
Win7本機IP: 192.168.2.102 shell
遠程服務器IP: 192.168.2.105windows
關於Win7下執行原代碼報錯問題的解決: 服務器
錯誤現象:TypeError: write() argument must be str, not bytes app
問題解決:F:\Django\paramiko-demo\paramiko-master\demos\interactive.py
Linux下paramiko的Demo遠程登陸執行交互命令:
下載Demo文件

上傳文件到本機Linux服務器:
omc@omc-virtual-machine:~$ cd paramiko_demo/ omc@omc-virtual-machine:~/paramiko_demo$ ll
Linux登陸其餘的Linux服務器
Linxu本機IP: 192.168.25.110
