红帽全球峰会7.8. 通过红帽对 Proxy 纠错
如果已尝试过所有这些故障排除步骤，或者您向将其教给红帽网络专业人员解决，红帽建议您利用 RHN Proxy 服务器的强大支持功能。
联络专业人员的方法之一是通过红帽知识库，它可提供大多数用户通常遇到问题的解决方案，并拥有用查找您的 Proxy 问题正确答案的鲁棒浏览和搜索界面。您可在 http://kbase.redhat.com 访问红帽知识库。
另外，红帽提供了一个名为 SoS Report 的命令行工具，一般我们知道的是其命令
sosreport。这个工具会收集您 Proxy 的配置参数、日志文件和数据库信息，并将其直接发送给红帽。
要使用这个工具获得 RHN Satellite 服务器信息，您必须安装
sos 软件包。作为 root 用户在 Satellite 服务器中输入 sosreport -o rhn 可生成报告。例如：
[root@satserver ~]# sosreport -o rhn
sosreport (version 1.7)
