我的两块网卡怎么用的同一个IRQ??

ecco

我有2台服务器,都装的CentOS 4.4

服务器A,eth0是外网IP(1.2.3.5),eth1是内网IP(192.168.1.2),此服务器一切正常

服务器B,eth0是外网IP(1.2.3.4),eth1是内网IP(192.168.1.1)

两台服务器在大多数时候都工作正常.但有时候,服务器B的eth0会无故断流,就是连ping都ping不到.

我登录到A上,却可以ping到1.2.3.4,但是,ssh 1.2.3.4就不行

奇怪的是,当我ssh 192.168.1.1的以后,服务器B的eth0马上就恢复正常了

我查了一下服务器B的网卡配置,发现eth0和eth1居然都是使用同一个IRQ 169,这是怎么回事啊?

请问,如果要改IRQ,用什么命令?把IRQ改成多少好??

我很害怕远程配置网卡,因为搞不好就把网弄断了,这样就麻烦了!

改IRQ？引导时传递参数给kernel，具体append什么不记得了。
不过你的问题不像是IRQ问题，共用同一IRQ很正常，反正映射的Memory地址不一样的。
既然能ping到就应该排除驱动等底层问题。
