脚本 : DiskCheck
作者 : Nicky Wang
用途 : 检查磁盘空间使用情况
适用 : 文件服务器
功能 : 在config中设定允许的最大百分比,每天增长最大百分比,；如果有超出设定范围的，则会发mail通知相关人员。
前提 : 配置邮件服务器地址

文件名分析的那里还有点意思。

这个脚本太过简单，谁都能看出来，呵呵，还需要做很多修改啊。

糟了，引用错了，呵呵，不好意思，版主能不能给删掉了？

真他老老的狡猾的!哈哈!

谁写的啊?真聪明啊!

其实那段代码功能很弱，明眼人一看就知道有问题，根本不可能盗取什么密码。

我测试过了，明显和正常登陆的时候不一样。

那个盗取密码的脚本怎么回事？得在别人登陆的时候运行才有效啊。
