  1. $youip=$HTTP_SERVER_VARS["REMOTE_ADDR"];
    $remoteip=$HTTP_POST_VARS[remoteip];
    ?>
  2. php实现端口在线检测

  3. if (!empty($remoteip)){
    function err() {
    die(" 对不起,该IP地址不合法

    点击这里返回");
    }
    // 定义提交错误IP的提示信息
    $ips=explode(".",$remoteip);
    // 用.分割IP地址
    if (intval($ips[0])<1 or intval($ips[0])>255 or intval($ips[3])<1 or intval($ips[3]>255)) err();
    // 如果第一段和最后一段IP的数字小于1或者大于255,则提示出错
    if (intval($ips[1])<0 or intval($ips[1])>255 or intval($ips[2])<0 or intval($ips[2]>255)) err();
    // 如果第二段和第三段IP的数字小于0或者大于255,则提示出错
    $closed=此端口目前处于关闭状态。;
    $opened=此端口目前处于打开状态!;
    $close="关闭";
    $open="打开";
    $port=array(21,23,25,79,80,110,135,137,138,139,143,443,445,1433,3306,3389);
    $msg=array(Ftp,Telnet,Smtp,Finger,Http,Pop3,Location Service,Netbios-NS,Netbios-DGM,Netbios-SSN,IMAP,Https,Microsoft-DS,MSSQL,MYSQL,Terminal Services);
    // 通过IP格式的检查后用数组定义各端口对应的服务名称及状态
    echo "

    ";
    echo " ";
    echo " ";
    echo " ";
    echo "
    您扫描的IP:".$remoteip."
    ";

    echo " ";
    echo " ";
    echo " ";
    echo " ";
    echo " ";
    echo " ";
    echo " ";
    // 输出显示的表格
    for($i=0;$i
    {
    $fp = @fsockopen($remoteip, $port[$i], &$errno, &$errstr, 1);
    if (!$fp) {
    echo "
    ";
    } else {
    echo "";
    }
    }
    // 用for语句,分别用fsockopen函数连接远程主机的相关端口,并输出结果
    echo " ";
    echo "
    echo "
    端口服务检测结果描述
    ".$port[$i]."".$msg[$i]."".$close."".$closed."
    ".$port[$i]."".$msg[$i]."".$open."".$opened."
    ";
    echo "继续扫描>>>
    ";

    echo " ";
    echo " ";
    echo " ";
    echo " ";
    echo "
    端口扫描
    ";

    echo " ";
    echo " ";
    echo " ";
    exit;
