我是靠谱客的博主知性棉花糖，最近开发中收集的这篇文章主要介绍ubuntu ppp拨号两分钟就掉线解决，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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。
[Dialer Defaults]
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。
