ubuntu10.04 和8.04下ppp拨号一点反应都没有

[fishly_0]

rt，我想试试桌面linux下的ppp拨号，下了ppp-2.4.4进行编译，但是在执行ppp-on的时候，一点提示都没有。如果单独执行pppd，那么是有一堆拨号的字符出现的。后来经过逐步排查，发现是脚本里pppd带的参数问题，主要有2个
1，如果有指定拨号端口，如：ttyS0或者ttyUSB0，那么执行拨号脚本一点反应都没有，在脚本里添加了echo语句，发现执行完exec就结束了，不会接着调用ppp-on-dialer脚本。
2，如果没有指定拨号端口，并且pppd带有其他参数，那么ppp-on-dialer脚本有执行，并且有几个字符提示
3，如果删除pppd所带的参数，那么执行ppp-on会出现一大堆的拨号字符，这个似乎是比较正常的。

问下有玩过ppp拨号的兄弟们，这是怎么回事阿？
脚本如下：
ppp-0n

#!/bin/sh
#
# Script to initiate a ppp connection. This is the first part of the
# pair of scripts. This is not a secure pair of scripts as the codes
# are visible with the 'ps' command.  However, it is simple.
#
# These are the parameters. Change as needed.
TELEPHONE=555-1212	# The telephone number for the connection
ACCOUNT=		# The account name for logon (as in 'George Burns')
PASSWORD=		# The password for this account (and 'Gracie Allen')
LOCAL_IP=0.0.0.0	# Local IP address if known. Dynamic = 0.0.0.0
REMOTE_IP=0.0.0.0	# Remote IP address if desired. Normally 0.0.0.0
NETMASK=255.255.255.0	# The proper netmask if needed
#
# Export them so that they will be available at 'ppp-on-dialer' time.
export TELEPHONE ACCOUNT PASSWORD
# 
# This is the location of the script which dials the phone and logs
# in.  Please use the absolute file name as the $PATH variable is not
# used on the connect option.  (To do so on a 'root' account would be
# a security hole so don't ask.)
#
DIALER_SCRIPT=/home/simon/usb_serial/Linux_dial/dial/ppp-on-dialer
#
# Initiate the connection
# 
# I put most of the common options on this command. Please, don't
# forget the 'lock' option or some programs such as mgetty will not
# work. The asyncmap and escape will permit the PPP link to work with
# a telnet or rlogin connection. You are welcome to make any changes
# as desired. Don't use the 'defaultroute' option if you currently
# have a default route to an ethernet gateway.
#
exec /home/simon/usb_serial/Linux_dial/dial/pppd debug lock modem /dev/ttyUSB0 38400 \
	asyncmap 20A0000 escape FF kdebug 0 $LOCAL_IP:$REMOTE_IP \
	noipdefault netmask $NETMASK defaultroute connect $DIALER_SCRIPT

ppp-on-dialer

#!/bin/sh
#
# This is part 2 of the ppp-on script. It will perform the connection
# protocol for the desired connection.
#
echo "ppp-on-dialer"
exec chat -v						\

我一般直接sudo pppoeconf拨号,然后一步步按照屏幕提示走的...

都没有手动编译过

看看这个Ubuntu的wiki

谢谢2位，其实我主要是想学习学习用ppp拨号的过程的。

解决了，还是把答案贴上来吧：
ppp的拨号输出可以在 /var/log/message 下查看

ppp拨号不成功，是因为我用的是wcdma的模块，不需要用户名密码，我把ppp-on-dialer的最后两行去掉，就可以拨上去了，如下：
ogin:--ogin: $ACCOUNT \
assword: $PASSWORD
