经验总结：Veritas BE备份Redhat ES4排错一例

Backup Exec RALUS备份 Redhat ES4出现的问题： 在Server端（192.168.66.100）和ES4（192.168.66.13）上分别安装好软件，安装完成后在ES4S的RALUS能够正常启动起来，通过server端的BEWS治理界面也能看到这个机器，但就是不能浏览， 本人也重新安装过两边软件，问题依然存在，在两台机器之间是没有防火墙的

  ralus.cfg内容如下：
  SOFTWARE\VERITAS\Backup Exec\Agent Browser\TcpIp\AdvertisementPort=6101
  Software\VERITAS\Backup Exec\Engine\Agents\Advertising Interval Minutes=60

报错如下： 经过多次调试排错，发现出现这个问题的原因并不在于软件和系统问题。最后发现是LINUX这边IPTABLE阻挡了连接请求。由此可见，我们往往把简单的问题想复杂了，从而犯下低级错误。此类技术工作还是需要一步一步扎实来做呀：） 具体如下： 另外提示：还有就是以后在安装时候，假如出现问题,最好安装英文软件，这样报的错误也好在support站点上来搜索帮助
