安装完archlinux 2013.10.01之后突然无法上网

Kelei · 2013-10-11 09:14:47

第一次安装arch。校园网，windows下是用pppoe用户名+密码连接的。用光盘安装，刚开始的时候不能上网，后来在wiki里找到一段和我网卡完全一样的：

按它的操作步骤配置好再用dhcpcd+pppoe-setup/pppoe-start就可以上网了。

成功完装完成之后，用同样的方法（启动dhcpcd+配置pppoe-setup）可以顺利连接网络，然后就用pacman安装了openbox等一些需要用到的软件。某次重启之后，进入系统就无法上网。
开始以为是系统的问题，但发现：即使我启动光盘的系统，用先前同样的方法，在live系统里面也变得无法上网了(dhcpcd始终报错)。也就是现在在live系统和安装好的系统里都无法上网。

ip link的结果是：

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp9s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT qlen 1000
    link/ether c8:0a:a9:69:86:30 brd ff:ff:ff:ff:ff:ff
3: wlp5s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000
    link/ether 00:26:c7:44:d7:06 brd ff:ff:ff:ff:ff:ff

我的dhcpcd.conf里面是这样的：

hostname
duid
option rapid_commit
option domain_name_servers, domain_name, domain_search, host_name
option classless_static_routes
option ntp_servers
require dhcp_server_identifier
nohook lookup-hostname
noipv4ll

dpcpcd enp9s0运行结果是：

尝试在dhcpcd.conf里加上

noipv6rs

之后，dhcpcd enp9s0的结果是：

另外，wiki里提到dhcpcd里连接失败的可以尝试使用dhclient，由于我装好的系统里还没有安装这个，所以没法尝试。但在光盘live系统里，使用dhclient没有报任何错误，pppoe-start同样但无法上网。

现在是怎么都连不上网络了，请问有谁可以帮帮我？谢谢

有 tcpdump 不？

百合仙子说：

有 tcpdump 不？

tcpdump -i enp9s0 -v

有这样的输出：

有 tcpdump 不？
tcpdump -i enp9s0 -v
有这样的输出：
...

既然你有，而且能把结果弄出来：

tcpdump -i enp9s0 -s 0 -vv -w log.pcap

然后把生成的 log.pcap 文件放出来。记得先开 tcpdump，然后再 dhcpcd。

哦好的稍等！开了tcpdump再开dhcpcd的话dhcpcd就不会自动退出吗？还有，运行到dhcpcd退出了就可以还是等tcpdump自己完成？

按你的提示运行了一下，但dhcpcd运行了不久之后连接不上就自动退出了。输出我不知道怎么放附件。。放了去度盘。。

log.pcap: http://pan.baidu.com/s/1gOvQr

另外，我怕文件太大了，我重新运行了一次，打算dhcpcd死掉就关掉log。没想到这次dhcpcd竟然没有死掉，但依然无法上网，无法ping任务网站，这次的日志是：

DHCP 正常，DNS 正常，但是 ping 没有回应。你 ping 你的网关（192.168.137.174）呢？wget baidu.com 呢？

DHCP 正常，DNS 正常，但是 ping 没有回应。你 ping 你的网关（192.168.137.174）呢？wget baidu.com 呢？

现在又不行了，这两天自动上不了之后，dhcpcd就没有成功连过，一直time out然后死掉。就刚刚那一次可以。

前边那个记录中开头部分，有人在进行 ARP 扫描。DHCP 服务器没有回应你的请求。

另外，你这网络里至少有两个网段啊，是什么网络环境呢？

网络我不是很懂，就校园网，只知道我们这里是一个账号可以多台电脑一起拨号用的……。请问我可以怎样知道我的网络环境啊？另外，意思是因为有人扫描，导致了DHCP服务器没有响应我的请求吗？

你们校园网不需要特别的客户端就可以用吗？

看上去是 DHCP 服务器出了问题的样子呢。别人上网都没问题？你在没有问题的系统上抓个联网过程的包看看呢？

不用。听说其它栋的需要锐捷，我们这里只要pppoe。我这里win7也一直没有任何问题。现在抓！

哦，我想起来了！PPPoE 的话，连上之后会出现一个 ppp 的网络接口（比如 ppp0）。你看看你有没有 ppp*，如果它没有 IP 地址的话你再给它 DHCP。

你说的是在dhcpcd和pppoe-start都连上之后吗？前几天能连上的时候连上了我有用ip link看过，是有的。但具体输出是什么不记得了。现在是我dhcpcd连不上……更不用说pppoe-start了，所有我看不到ppp*有没有IP或其它输出。

dhcpcd 之前、pppoe-start 之后。
