前一段做了一个监控程序，触发事件后实现telnet到Sco unix执行命令并取得命令结果，想了几天终于完成，特和大家分享：
一、安装TelnetTool控件（提供下载）
二、VFP代码部分：
LOCAL telnet1 telnet1=CREATEOBJECT("Dart.Telnet.1") Telnet1.Timeout = 100 Telnet1.TermType = "vt100" False=.t. True=.t. vbCrLf=CHR(13)+CHR(10) ** logfile = "Host" + HostIP + ".log" ** Telnet1.Trace(logfile, False, True, vbCrLf + "---> ", vbCrLf + "<--- ") thisform.AddLog(Tsys_kind,"正在连接主机 " + HostIP + " ..." + vbCrLf) ok = Telnet1.Connect(HostIP, 23) IF ok="" thisform.AddLog(Tsys_kind,"银联前置["+HostIP+"]连接失败!同银联中心链路无法检查。") thisform.showinfo("99","错误：银联前置连接失败!") thisform.warn thisform.command4.Picture="deng3.gif" thisform.command4.refresh telnet1.close RETURN ELSE telnet1.close Telnet1.Timeout = 10000 Telnet1.Connect(HostIP, 23) ENDIF thisform.AddLog(Tsys_kind,"已连接" + vbCrLf)
Data = ""
Telnet1.Search (@Data, "login:")
* thisform.AddLog( Tsys_kind,Data)
Telnet1.Send(User_name + vbCrLf) Data = ""
Telnet1.Search(@Data, "PassWord:") * thisform.AddLog(Tsys_kind,Data)
Telnet1.Send (User_pwd + vbCrLf) Data = ""
Telnet1.Search(@Data, ">") * thisform.AddLog(Tsys_kind,Data)
Telnet1.Send ("su" + vbCrLf) Telnet1.Search (@Data, "Password:") * thisform.AddLog(Tsys_kind,data) Telnet1.Send(root_pwd + vbCrLf) Telnet1.Search(@Data, "#") * thisform.AddLog(Tsys_kind,Data)
Telnet1.Send(shell_cmd + vbCrLf) Telnet1.Search(@Data, "#") * thisform.AddLog(Tsys_kind,data)
***************取出的数据ok = VAL(STREXTRACT(data,"/","/",3))
IF ok>WP04 && Warn Point
thisform.showinfo("01","★警告：银联中心网络延时[9.234.12.21]！当前值:"+ALLTRIM(STR(ok,10,2))+"设定值："+ALLTRIM(STR(WP04,10,2)))
thisform.addlog(Tsys_kind,"★警告：银联中心网络延时[9.234.12.21]！当前值:"+ALLTRIM(STR(ok,10,2))+"设定值："+ALLTRIM(STR(WP04,10,2)))
......&&触发事件
ENDIF
