pppoe server的pap问题

ghoulr

我想用一个linux服务器，来模拟测试路由器的pppoe拨号的，环境里就只有一个服务器，ethernet card一个(eth0)，与路由器(asus wl-500gP)的wan port连接起来。

发行版是suse10.1，带的ppp是ppp-2.4.3-31

然后去下载了rp-pppoe 3.8，然后
./configure --enalbe-plugin
make
make install

/etc/ppp/pap-secrets配置如下：
#client     server    secret     IP address
"usr"       *            "123"       *

/etc/ppp/chap-secrets的配置和pap-secrets一样

/etc/ppp/pppoe-server-options配置如下：
+pap
+chap
login
lcp-echo-interval 30
lcp-echo-failure 4
ms-dns 10.0.0.1

然后运行：
modprobe pppoe
pppoe-server -I eth0 -N 2 -L 10.0.0.1 -R 10.0.0.100 -r -u

client端提示：
Jan  1 00:05:23  pppd[86]: Starting link
Jan  1 00:05:23  pppd[86]: PPP session is 1
Jan  1 00:05:23  pppd[86]: Connect: ppp0 -> eth0
Jan  1 00:05:26  pppd[86]: Remote message: User not known to the underlying authentication module
Jan  1 00:05:26  pppd[86]: PAP authentication failed
Jan  1 00:05:26  pppd[86]: Connection terminated.
Jan  1 00:05:26  pppd[86]: Exit.

然后我用cat var/log/messages去看，纪录信息如下：
Oct 28 03:46:06 qt5 pppd[7795]: pppd 2.4.3 started by root, uid 0
Oct 28 03:46:06 qt5 pppd[7795]: Using interface ppp1

Oct 28 03:46:09 qt5 pppoe-server[7794]: Sent PADT


请问问题出在哪里，是我的pap-scerets写的不对么？

后来我试着把pap关掉，只留下chap
但是换了一个出错信息。。。

服务器的log是这样的：

Using interface ppp0
Connect: ppp0 <--> /dev/pts/2
LCP: timeout sending Config-Requests
Connection terminated.

client端也是报LCP: timeout sending Config-Requests

我已经弄了4天了，跟着很多资料去做，始终都是这样。。。

而且，资料说的用-k来跑内核模式的pppoe，但是总是报错说这个参数是无效的，我还为这个重新编译过内核。

请大大们帮忙看看吧。

把rp-pppoe 3.8换成3.5后，问题解决了，pap还是会得不到验证，但是换成chap后可以建立连接了，但是会提示CCP timeout。。。

这是客户端的信息：

服务器端的log文档里是这样的：

Using interface ppp0
Connect: ppp0 <--> /dev/pts/1
Script /etc/ppp/auth-up finished (pid 7697), status = 0x0
local  IP address 10.0.0.1
remote IP address 10.0.0.100
Script /etc/ppp/ip-up finished (pid 7700), status = 0x0

请问有人知道为什么有那样的log么

用笨办法解决了，在pppoe-server-options里加参数noccp，将压缩禁用后就没有这个提示了。。。。。。
