本文實(shí)例講述了Python socket套接字實(shí)現(xiàn)C/S模式遠(yuǎn)程命令執(zhí)行功能。分享給大家供大家參考，具體如下：

一. 前言

要求:

使用python的socket套接字編寫(xiě)服務(wù)器/客戶機(jī)模式的遠(yuǎn)程命令執(zhí)行腳本。

serverCmd.py 遠(yuǎn)程機(jī)器上用來(lái)執(zhí)行客戶端發(fā)送命令的腳本
clientCmd.py 本地機(jī)器上,向遠(yuǎn)程服務(wù)器發(fā)送命令的腳本
servers.txt  本地機(jī)器上,存放所有的遠(yuǎn)程服務(wù)器IP地址文件(僅支持第一個(gè)IP)

發(fā)送:cmd [command]形式消息,讓遠(yuǎn)程主機(jī)執(zhí)行命令(本地主機(jī)無(wú)回顯)

發(fā)送:close session消息,雙方關(guān)閉會(huì)話。

二. 源碼

注:

1. 代碼注釋較少,建議有一定套接字編程基礎(chǔ)。
2. 或者直接簡(jiǎn)單部分修改IP使用。
3. clientCmd.py和servers.txt(修改IP地址后)放在同一目錄。
4.程序?yàn)楹?jiǎn)單Demo,僅為學(xué)習(xí)記錄。

python serverCmd.py

[+] Server is running on port:47091 at 20161013 17:50:19
[+] Connect success -> ('192.168.0.241', 4255) at 20161013 17:50:32
[+] Receive:hello
[+] Receive:你好
[+] Receive:cmd ip
'ip' 不是內(nèi)部或外部命令，也不是可運(yùn)行的程序
或批處理文件。

[+] Receive:cmd ipconfig
