我安装了 VestaCP 并将他们的邮件服务器用于我的域邮件。但是当我在我的服务器上运行 netstat 时，它显示了一些奇怪的连接。到目前为止，我的邮件服务器没有问题，我只是担心这些连接。

我的服务器是否遇到任何安全问题？

# netstat -antp

今天在 Redhat Linux 6.5 上安装 Oracle 11gR2 时出现以下错误。

我遵循此链接中的说明：http ://public-yum.oracle.com/

在我调用这个命令之后：

# yum 安装 oracle-rdbms-server-11gR2-preinstall

=> 好的

# 百胜更新

=> 我得到了这些错误：

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
