⑴、网卡eth被删除后,新加的网卡成了eth,如何让从eth开始
⑵[rootrac ~]# ifconfig
⑶eth Link encap:Ether HWaddr :::::
⑷i addr:... Bcast:... Mask:...
⑸i addr: fe:::ff:fe:/ Scope:Link
⑹UP BROADCAST RUNNING MULTICAST MTU: Metric:
⑺RX packets: errors: dropped: overruns: frame:
⑻TX packets: errors: dropped: overruns: carrier:
⑼collisions: txqueuelen:
⑽RX bytes: (. KiB TX bytes: (. KiB
⑾eth Link encap:Ether HWaddr :C::E:F:B
⑿i addr:... Bcast:...Mask:...
⒀i addr: fe::c:ff:fee:fb/ Scope:Link
⒁UP BROADCAST RUNNING MULTICAST MTU: Metric:

⒃TX packets: errors: dropped: overruns: carrier:
⒄collisions: txqueuelen:
⒅RX bytes: (. KiB TX bytes: (. b
⒆同问题类似,即可以手动的修改-persistent-.rules文件,将对应的MAC地址与网卡序号改成想要的,也可以直接删除该文件,重启系统后,RedHat会自动的创建该文件,并从开始计数。
⒇删除文件,重启系统
⒈[rootrac ~]# mv /etc/udev/rules.d/-persistent-.rules /etc/udev/rules.d/
⒉-persistent-.rules.bak
⒊[rootrac ~]# reboot
⒋再次查看,会发现已经从eht开始
⒌[rootrac ~]# ifconfig
⒍eth Link encap:Ether HWaddr :::::
⒎i addr:... Bcast:... Mask:...
⒏i addr: fe:::ff:fe:/ Scope:Link

②、每次重启网卡,总是提示
③Active connection path: //freedesktop/workManager/ActiveConnection/
④此时网卡也可以正常通信,这个是因为RedHat自己开发的workManager管理工具和/etc/sysconfig/work-scripts/ifcfg-ethx配置不同步造成的。
⑤要消除这个提示,请关闭workManager服务即可:
⑥[rootrac ~]# service work restart
⑦Shutting down loopback interface: [ OK ]
⑧Bringing up loopback interface: [ OK ]
⑨Bringing up interface eth: Active connection state: activated
⑩Active connection path: //freedesktop/workManager/ActiveConnection/ [ OK ]
ⅠBringing up interface eth: Active connection state: activated
ⅡActive connection path: //freedesktop/workManager/ActiveConnection/ [ OK ]
Ⅲ关闭workManager服务
Ⅳ[rootrac ~]# service workManager stop
ⅤStopping workManager daemon: [ OK ]
Ⅵ[rootrac ~]# service work restart
ⅦShutting down loopback interface: [ OK ]
ⅧBringing up loopback interface: [ OK ]
ⅨBringing up interface eth: [ OK ]
ⅩBringing up interface eth: [ OK ]
㈠、重启网卡出现提示:
㈡Bringing up interface eth: Determining if ip address ... is already in use for device eth.。。
㈢Bringing up interface eth: Determining if ip address ... is already in use for device eth.。。
㈣该警告一般是由于网卡解析arp协议导致的,可在网卡的配置文件中加入ARPCHECK=NO参数来屏蔽该检查
㈤[rootrac ~]# cat /etc/sysconfig/work-scripts/ifcfg-eth
㈥TYPE=Ether
㈦BOOTPROTO=none
㈧IPADDR=...
㈨GATEWAY=...
㈩DEFROUTE=yes
IPV_FAILURE_FATAL=yes
IPVINIT=no
NAME=eth
UUID=d---bb-acac
ONBOOT=yes
HWADDR=:::::
LAST_CONNECT=
ARPCHECK=no
再次启动网卡,一切正常
[rootrac ~]# service work restart
Shutting down interface eth: [ OK ]
Shutting down interface eth: [ OK ]
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth: [ OK ]
Bringing up interface eth: [ OK ]
上面就是RedHat.网卡常见问题及解决方法的介绍了,如果你在联网的时候出现连接不上的情况,可以看看是不是网卡出现了问题,可用本文介绍的相关方法进行处理。
