我的服务器正在发送垃圾邮件,我无法找出发送它们的脚本.

电子邮件全部来自nobody @ myhost,因此禁用了cpanel,不允许任何人发送电子邮件

现在至少他们不会外出,我一直接受他们.这是我收到的邮件：

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

  [e-mail]
    Mail sent by user nobody being discarded due to sender restrictions in WHM->Tweak Settings

------ This is a copy of the message,including all the headers. ------

有没有办法找到哪个脚本或哪个用户正在生成这些脚本？

解决方法

Linux恶意软件检测( http://www.rfxn.com/projects/linux-malware-detect/)安装非常简单:).点击此链接,下载 http://www.rfxn.com/downloads/maldetect-current.tar.gz.此文件的链接位于网页的最顶部.然后解压缩此存档,通过在终端中运行cd转到新创建的目录.
在目录中运行

sudo ./install.sh

这将把扫描仪安装到您的系统.要执行扫描本身,您将运行

sudo /usr/local / sbin / maldet -a /

-a选项在这里意味着你想要扫描所有文件.使用-r代替仅扫描最近的. /指定应执行扫描的目录.所以只需将其更改为您想要的任何目录.
