adsl: Configuration label not found

一、修改/etc/ppp/ppp.conf 如下：
default:
set log Phase Chat LCP IPCP CCP tun command
ident user-ppp VERSION (built COMPILATIONDATE)
set device PPPoE:ale0     
set speed sync
set mru 1492
set mtu 1492
enable dns # request DNS info (for resolv.conf)
add default HISADDR
adsl:
set authname myname  # adsl 帐户
set authkey 8888888  # adsl 密码
set dial
set login

二、在/etc/rc.conf末尾添加如下：
ppp_enable="YES"
ppp_mode="ddial" #断线重拔
ppp_profile="adsl"

#ppp -ddial adsl
出现如下提示：
