求助：L2TP client in Fedora Core 6, connected but no ping

KinSprite

After l2tp conneting , I tried to ping the remote IP. In Network Tool, both the number of RX and TX packets increased one by one , but no ping received.

Here is the message:

try arping

KinSprite

非常感谢你的回答。

arping -I ppp0 58.207.255.110
是这个吗？  58.207.225.110 是远程IP.

我主要是想在linux也能使用教育网直通车上外网。

KinSprite

arping 不能用到这个。
我把 proxyarp 改为 noproxyarp， 也不行。
再把firewall关闭 与 让SELinux允许，也不行。 ):

Yuri

中国人说什么洋文啊?
tcpdump -i ppp0
能听到东西麽?

KinSprite

没有听到什么声音。  ping 58.207.255.110 时看到
eq 14, length 64
16:49:50.231459 IP 58.207.164.9 > 58.207.255.110: ICMP echo request, id 12811, seq 15, length 64
16:49:51.231442 IP 58.207.164.9 > 58.207.255.110: ICMP echo request, id 12811, seq 16, length 64

16 packets captured
32 packets received by filter
0 packets dropped by kernel

全是发出去的，没有进来的!

还是用pppoe稳定些，呵呵

Yuri

不好意思这个听是监听数据包的听.
就是能发不能收咯.
看看服务器端的路由.
去服务器端ping 记得加-i指定端口

KinSprite

还是用pppoe稳定些，呵呵

pppOE能用到 L2TP 协议上吗 ？

去服务器端ping 记得加-i指定端口

服务器是教育网直通车的,  在widnow下面我连接成功且可以通过它上外网.  我这里是教育网, 不能上国外网站。

有没有办法 把  Connect: ppp0 <--> /dev/pts/5 改为Connect: ppp0 <--> /dev/eth0 ?? 这个方法是否可以连接出去 ？？
