Symantec Backup Exec 11d RALUS通信错误

时间:2020-03-05 18:41:45  来源:igfitidea点击:

我正在尝试使用Symantec Backup Exec 11d(Rev 7170)对RedHat Enterprise Linux v4服务器进行文件系统备份。备份服务器是Windows Server 2003.

我可以浏览目标服务器以创建选择列表,当我进行测试运行时,它会成功完成。

但是,当我运行真实备份时,该作业在"处理"阶段立即失败,并显示以下错误:

e000fe30发生通信故障。

我尝试打开端口(10000,1025-9999),等等。但是没有喜悦。有任何想法吗?

解决方案

回答

当然,这听起来像是防火墙问题。尝试停止iptables,然后重新运行。同样,RALUS可以转储日志文件,这可能会给更多文件带来麻烦。

我本人使用较旧的UNIX代理,该代理使用端口6101 IIRC,但我相信较新的客户端将tcp / 10000用于控制,将1024-65535用于传输。

不得已的方法是启动网络嗅探器。 ;)

为了弄清楚答案,解决方案是打开1024-65535之间的tcp端口。

iptables看起来像这样:

我执行了以下命令以添加新规则:

[root@MYSERVER ~]# iptables -I RH-Firewall-1-INPUT 14 -p tcp -m tcp --dport 1024:65535 -j ACCEPT

然后他们看起来像这样:

确认iptables有效后,请保存它:

[root@MYSERVER ~]# service iptables save
