嵌入式linux pppoe 拨号失败

我有两个虚拟机都是linux 其中一个做pppoe-server,另外一个做client

从client拨号server 没有问题，server执行chap验证，已配置好

现在我从嵌入式linux的板子上， 执行同样的操作（配置文件同虚拟机client一样），但是拨号失败

板子的配置文件如下：

/ # cat /etc/ppp/chap-secrets 
# Secrets for authentication using CHAP
# client server secret IP addresses
####### redhat-config-network will overwrite this part!!! (begin) ##########
####### redhat-config-network will overwrite this part!!! (end) ############
"tc" * "333333" *
/ # 

/ # 
/ # cat /etc/ppp/pap-secrets 
# Secrets for authentication using PAP
# client server secret IP addresses
####### redhat-config-network will overwrite this part!!! (begin) ##########
####### redhat-config-network will overwrite this part!!! (end) ############
"tc" * "333333" *

/ # cat /etc/ppp/options 
#lock

login
plugin /etc/ppp/rp-pppoe.so
lcp-echo-interval 10
lcp-echo-failure 2

ipcp-accept-local

/ # cat /etc/ppp/pppoe-server-options

也用过pppoe的 pppoe-setup和pppoe-start均不成功。
