网络问题（会被人歧视么？）

liangfaxiang

好长一段时间，我都是在ubuntu下玩弄，习惯了gnome，我发现我自己忘记了最初记下来的命令行，忘记了在文本界面下配置系统
不久前一朋友问我你这样与在windows下有什么区别我居然回答不了——确实背离初衷太远了

于是某日我决定再次来到archlinux的怀抱，可是习惯了

networkmanager，我居然连网络都不会配置了！！！！
还记得之前发过一个帖子，当时我的网卡不能被0.7的识别，而今发这么一个帖子，不知道会不会被歧视？……
我在校园网下
windows下的端口信息如下

1. 
   
2. 实际地址: 00-E0-B0-E2-7B-26
   
3. IP 地址: 211.66.**.78
   
4. 子网掩码: 255.255.255.0
   
5. 默认网关: 211.66.**.254
   
6. DNS 服务器: 202.112.17.33, 202.38.193.33
   
7. WINS 服务器:

1. ping 127.0.0.1

复制代码

没有问题
而

1. ping -b 211.66.**.254

复制代码

却始终ping不通

反复看了很久wiki，也google了很久，但是ping 网关211.66.**.254还是不行，ping学校的主页地址www.scut.edu.cn返回是未知主机……
难道是gateway的设置？(其实gateway实在搞不懂是什么东西……）
那位大侠帮忙？万分感谢？

写了这么多都没说到点上！是固定IP还是DHCP？网卡驱动上了吗？lspci看一下

wd_afei

eth0="eth0 211.66.**.78 netmask 255.255.255.0 broadcast 211.66.**.254"
INTERFACES=(eth0)

# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
#   - prefix an entry in ROUTES with a ! to disable it
#
gateway="default gw 211.66.**.254"
ROUTES=(gateway)

是真的写的 ** 还是贴出来的时候改了？

贴一下 sudo ifconfig, sudo route -n

楼主的配置很奇怪。
我用的也是静态IP，gateway都是xxx.xxx.xxx.1，而 broadcast则为 xxx.xxx.xxx.255
希望对你有帮助。

至于 ping 网关211.66.**.254 不通 可能是网关不允许ping。我的就是这样，但是能正常使用网络。

谢谢，如果是dhcp那我就不用管那个配置了……另外关于网卡驱动我记得之前在网上看见某人说ping 127.0.0.1 正常的话就是网卡正常使用了

这个明显是我贴出来的时候改的……

关于ping 网关
我对比过在视窗下，ok的
而且我也记得之前在ubuntu下也没有问题

另外关于网卡驱动我记得之前在网上看见某人说ping 127.0.0.1 正常的话就是网卡正常使用了

咳..127.0.0.1是本机IP啊..和网卡有什么关系?..你没网卡也能ping这个的吧?
怎么你没有这行的 lo="lo 127.0.0.1" ...- -..!!


broadcast 211.66.**.254 把254改成255看看.

还有你确定你的网卡工作正常了?

难免有错

我想问下，“USEDIRECTISA"这个选项有什么用？

jarryson

broadcast是不能和网关一个地址的，不要想当然。我以前也是这样。

至于USEDIRECTISA这个，新的rc.conf是关闭的，原来是yes。。
