ｄｅｌｌ的笔记本，ｂｒｏａｄｃｏｍ的无线网卡，不过已经安装驱动了，
fedora, 2.6的内核，
在进入系统的时候，会跳出字符界面检测到网卡，并要求设置ｉｐ地址，但之后启动过程中会出现：
can not change name of lo to eth0, device or resource busy interface,
'eth0' not found,
进入系统之后，使用ifconfig也看不到eth0，只有ｌｏ，加入 －ａ 选项，看到ｌｏ 还有一个
sit0,link encap:ipv6-in-ipv4, noarp mtu: 1480 metric :1
使用ifup eth0 up 同样出现 can not change name of lo to eth0, device or resource busy interface,
请问是哪里除了问题呢？ 该怎样解决，
谢谢，

首先要搞清楚你的网卡驱动安装的接口名称是 eth0 还是 wlan0 什么的，可以在 /var/log/messages 里面查看；如果安装的是 eth0，那么 'eth0' not found 说明驱动没有正常工作；
其次检查 /etc/network 下面的设定(fedora可以在类似的目录里面)。
sit0 是做 IPv4/IPv6 的虚拟接口。
还有，2.6 太笼统了，2.6.x 后面的 x 不同，网卡的具体设置方法也有可能不同。

谢谢你的回答，
我在/val/log/message 里面查找下，没有 wlan， 部分如下，

发现虽然检测到硬件但是启动ｉｐｗ驱动时候出错， ipw2200_boot.fw load failed 后面也就没有注册设备，
在系统里面搜索，发现已经安装 ipw2200_boot.fw 等，
检查驱动版本，是ipw2200-0.1， 内核是 2.6.5-1.358，
上 http://ipw2200.sourceforge.net/ 看到这样一段，
Firmware files fail to load even if installed
In some kernel configurations (users have most frequently reported the problem only with 2.6.9), the default timeout value for the hotplug subsystem is too low. You may have this problem if you see the following in your kernel log (via dmesg or /var/log/messages):
ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.0.1
ipw2200: Copyright(c) 2003-2004 Intel Corporation
ipw2200: Detected Intel PRO/Wireless 2200BG Network Connection
ipw2200: ipw-2.2-boot.fw load failed: Reason -2
ipw2200: Unable to load firmware: 0xFFFFFFFE
ipw2200: failed to register network device
ipw2200: probe of 0000:00:0b.0 failed with error -5
To work around this, you can increase the default timeout value:
echo 100 > /sys/class/firmware/timeout
and then reload the ipw2200 module. If this corrects your problem, you may wish to add the above line to your system startup scripts prior to the point at which the driver module would be loaded.
The other most common reason for getting the above error is that the firmware files are not installed in the correct location. Please see the INSTALL document for information on installing the firmware files.
我输入
echo 100 > /sys/class/firmware/timeout 后重新ｌｏａｄ ipw2200.ko， 在/val/log/message 里面看到， ipw2200: Detected Interl PRO/Wireless 2200BG Network Connection
之后用 ifconfig -a 除了 lo , sti0 可以看到一个新的设备，
dev6909 Link encap:Ethernet HWaddr 00:0E:35:5C:1C:4E
BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0

collisions:0 txqueuelen:1000
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
Interrupt:11 Base address:0xa000 Memory:fafff000-faffffff
但是ifup dev6909
[root@localhost /]# ifup dev6909
/sbin/ifup: configuration for dev6909 not found.
[root@localhost /]# ifup eth0
cannot change name of lo to eth0: Device or resource busy
interface 'eth0' not found
cannot change name of lo to eth0: Device or resource busy
cannot change name of lo to eth0: Device or resource busy
interface 'eth0' not found
cannot change name of lo to eth0: Device or resource busy
Device eth0 has different MAC address than expected, ignoring.
[root@localhost /]# ifup eth1
ipw2200 device eth1 does not seem to be present, delaying initialization.
在 /etc/sysconfig/network-scripts 里面有如下配置文件，
[root@localhost network-scripts]# ls
ApmodeCfg-eth1 ifdown-ipsec ifup-ipsec ifup-sl
heliifconfig ifdown-ipv6 ifup-ipv6 ifup-wireless
ifcfg-eth0 ifdown-isdn ifup-ipx init.ipv6-global
ifcfg-eth1 ifdown-post ifup-isdn keys-eth1
ifcfg-lo ifdown-ppp ifup-plip labifcfg-eth1
ifcfg-net ifdown-sit ifup-plusb network-functions
ifcfg-rausb0 ifdown-sl ifup-post network-functions-ipv6
ifdown ifup ifup-ppp
ifdown-aliases ifup-aliases ifup-routes
ifdown-ippp ifup-ippp ifup-sit
其中，
[root@localhost network-scripts]# cat ifcfg-eth1
# Intel Corp.|Intel(R) PRO/Wireless 2200BG
DEVICE=eth1
ONBOOT=yes
BOOTPROTO=static
IPADDR=202.38.214.222
NETMASK=255.255.255.0
GATEWAY=202.38.214.254
这里的ｉｐ是在开机检查到硬件时设置的，
并且如果重载 ipw2200.ko模块， 检测到的硬件并 ifconfig -a 的设备名 dev6909 会变化为， devXXXX， 后面为随机的数字，
请问我怎样才能使用到无线网卡呢？？
因为内核，还有网卡驱动都是之前的师兄装的，也搞不清楚他里面怎么配置的，

http://ipw2200.sourceforge.net/
这一页里面讲了：
Requirements：
In order to use the IPW2200 driver you will need the following:
1. Linux (of course) with a 2.6.8+ kernel
你说你的内核是 2.6.5-1.358，这里会不会有问题？
还有你的network-scripts目录下只有几个 ifcfg-* (eth0/eth1/lo...), ifup dev6909 肯定不会工作的，必须有相应的 ifcfg-dev6909 脚本才行。我觉得还是驱动没有加载正确，应该是用 eth0 这样标准接口的
另外，似乎还需要用 iwconfig 设定一些无线方面的东西的。无线和有线不同，需要设置 tunnel、mode (adhoc/ap)、加密key等等。

2.6.8+是对ipw2200的新版本来说的，
机器上使用的是0.1的版本，看安装文档对2.6.5的内核是支持的，
因为系统的安装和使用都是以前师兄留下的，所以很多东西不知道还有不有用，也不知道该怎么用，使用的这个内核甚至连ｘ-window都启动不了，
上面提到过，系统可以检测到硬件，而且在lsmod里面也可以看到ipw2200.ko模块，错误发生在
ipw2200_boot.fw load failed ,然后后面不能注册设备名，
之后按 http://ipw2200.sourceforge.net/ 提示，
echo 100 > /sys/class/firmware/timeout
重新加载ipw2200.ko模块，可以找到硬件，就是dev6090，问题是我并不知道这个设备名怎么来的，在哪里设置，而且，上面也提到，每次重载，他的设备名会变化的，比如第二次重载可能变成， dev3851等，
