【求助】debian下用wvdial拨号，通过手机上网，每2分钟就掉线(已解决)
debian下用wvdial拨号，通过手机上网，每2分钟就掉线/var/log/messages中的信息：
pppd 2.4.4 started by root, uid 0
Using interface ppp0
Connect: ppp0 <--> /dev/ttyACM0
appear to have received our own echo-reply!
Remote message: PAP access OK
PAP authentication succeeded
replacing old default route to eth1
localIP address 10.239.165.140
remote IP address 10.239.165.0
primary DNS address 211.138.200.69
secondary DNS address 211.103.13.101

No response to 4 echo-requests
Serial link appears to be disconnected.
Connect time 1.8 minutes.
Sent 9178 bytes, received 30508 bytes.
Connection terminated.
Exit.
这一句：No response to 4 echo-requests，但不知道是在ping哪里啊？
查pppd的出错代码：The link was terminated because the peer isnotrespondingto echo requests.
同上面的出错信息一致，但不知道是哪里没反应啊？
[ Edited byls400 on 2008-8-18 14:18 ] 我连ubuntu下的拨号都没搞定，绑定了 在ubuntu下刚用蓝牙gprs的时候也这样2分钟断线，解决方法我忘记了好像是哪个配置文件里面因为找不到dns回执所以强制断线。bs一下linux的不易用性。 Posted by HOOP on 2008-8-17 19:25 http://www.ibmnb.com/images/common/back.gif

大哥,你还是用拼音吧........那样不会乱码........ read /etc/ppp/options and modify two items and ok. 楼上 的ubuntu怎么弄 用cmwap的乱码推荐用网页浏览加速器cmwap版 呵呵，从网上到处搜wvdial加上把/etc/ppp/option读了一遍，问题终于解决了。
0、以下操作均在root用户下，我用的手机是treo680,装好软件usbmodem，在手机上运行usbmodem
1、安装wvdial，我用的是debian，apt-get install wvdial ppp
2、运行wvdial，会生成/etc/wvdial.conf,按你的实际情况修改一下，网上都有，现付上我用的。
Init1 = at+cgdcont=1,"ip","cmwap"
stupid Mode = yes
Modem Type = USB Modem
ISDN = 0
Phone = *99***1#
Modem = /dev/ttyACM0
Username = any
Carrier Check = no
Password = any
Baud = 460800
New PPPD = yes
3、运行wvdial,已经能拨号上网了，但现在有一个问题，就是每2分钟就掉线，解决的方法是
4、读/etc/ppp/options其中有两行：
# If this option is given, pppd will send an LCP echo-request frame to the
# peer every n seconds. Normally the peer should respond to the echo-request
# by sending an echo-reply. This option can be used with the
# lcp-echo-failure option to detect that the peer is no longer connected.
lcp-echo-interval 30
# If this option is given, pppd will presume the peer to be dead if n
# LCP echo-requests are sent without receiving a valid LCP echo-reply.
# If this happens, pppd will terminate the connection.Use of this
# option requires a non-zero value for the lcp-echo-interval parameter.
# This option can be used to enable pppd to terminate after the physical
# connection has been broken (e.g., the modem has hung up) in
# situations where no hardware modem control lines are available.
lcp-echo-failure 4
明白为什么是2分钟就掉线了吧，把那两项注释掉，再拨号上网就没问题了。
5、上网与ie一样，要加代理10.0.0.172：80,debian的apt-get 更新，也要加代理，
在/etc/apt/下添加文件apt.conf,内容：
Acquire::http::Proxy "http://10.0.0.172:80";
不要忘了最后的分号。
