2 遠(yuǎn)程監(jiān)控程序 編程：研究生 唐鄭熠
這個(gè)個(gè)遠(yuǎn)程監(jiān)控程序，以命令行“ldc -s”運(yùn)行時(shí)，是作為服務(wù)器運(yùn)行；
以命令行“ldc –c IP”(IP為服務(wù)器IP地址)運(yùn)行時(shí)，是作為客戶端運(yùn)行。
服務(wù)器向客戶端發(fā)送指令“A”或“B”，若發(fā)送指令A(yù)，則客戶端控制計(jì)算機(jī)自動(dòng)關(guān)機(jī)；
若發(fā)送指令B，則將計(jì)算機(jī)所有的擊鍵記錄下來(lái)發(fā)送給服務(wù)器。
其中，ASCII值為32～128的可見ASCII字符直接輸出，
其它的不可見ASCII字符以“(%d)”的形式輸出，即括號(hào)加上該字符的ASCII值。
