为什么网卡必须在转换运行级别以后才能通？

jodgen

有台机器非常奇怪，有两块网卡

不管默认运行级别是3还是5，启动以后A网卡能通，B网卡ping不通，但把运行级别换一下就通了，不需要改配置，也不需要动任何硬件。看配置看不出什么问题，求助，可能会是哪方面的问题呢？

syshz

不同的运行级别对应不同的配置文件。您可以在/etc/rc.d/rcn.d  n为运行级别。这下面找到不同运行级别启动的服务。 S是启动 K是杀死。

runlevel 怎么换的?

runlevel 怎么换的?

init 3 或者init 5

MS很奇怪，那么这2个level在/etc/rc[35].d/*
这么比较 ls -l   /etc/rc3.d/* > a.tmp ;ls -l /etc/rc5.d/* > b.tmp;diff a.tmp b.tmp

貌似没啥区别：

[root@Webquery ~]# ls -l   /etc/rc3.d/* > a.tmp ;ls -l /etc/rc5.d/* > b.tmp;diff a.tmp b.tmp

伙计把dmesg贴一下，机器重启过程的日志能提供一下不？感觉太奇怪了。道理上不应该这样。

不同的运行级别对应不同的配置文件。您可以在/etc/rc.d/rcn.d  n为运行级别。这下面找到不同运行级别启动的 ...

感觉这个解释好像没有问题

@方兆国  转换运行级才能通 ？ 3、5应该都没问题的，这个问题要请教  @chenyx

    我当初的理解就是如果init 3下的配置有问题，那么，在init 3下就不能正常运行，否则无法解释在init 5下可以正常运行
