我的兩塊網(wǎng)卡怎么用的同一個(gè)IRQ??

ecco

我有2臺(tái)服務(wù)器,都裝的CentOS 4.4

服務(wù)器A,eth0是外網(wǎng)IP(1.2.3.5),eth1是內(nèi)網(wǎng)IP(192.168.1.2),此服務(wù)器一切正常

服務(wù)器B,eth0是外網(wǎng)IP(1.2.3.4),eth1是內(nèi)網(wǎng)IP(192.168.1.1)

兩臺(tái)服務(wù)器在大多數(shù)時(shí)候都工作正常.但有時(shí)候,服務(wù)器B的eth0會(huì)無(wú)故斷流,就是連ping都ping不到.

我登錄到A上,卻可以ping到1.2.3.4,但是,ssh 1.2.3.4就不行

奇怪的是,當(dāng)我ssh 192.168.1.1的以后,服務(wù)器B的eth0馬上就恢復(fù)正常了

我查了一下服務(wù)器B的網(wǎng)卡配置,發(fā)現(xiàn)eth0和eth1居然都是使用同一個(gè)IRQ 169,這是怎么回事啊?

請(qǐng)問(wèn),如果要改IRQ,用什么命令?把IRQ改成多少好??

我很害怕遠(yuǎn)程配置網(wǎng)卡,因?yàn)楦悴缓镁桶丫W(wǎng)弄斷了,這樣就麻煩了!

改IRQ？引導(dǎo)時(shí)傳遞參數(shù)給kernel，具體append什么不記得了。
不過(guò)你的問(wèn)題不像是IRQ問(wèn)題，共用同一IRQ很正常，反正映射的Memory地址不一樣的。
既然能ping到就應(yīng)該排除驅(qū)動(dòng)等底層問(wèn)題。
