linux pptp client的撥號問題
在linux下用pptp client，撥號成功，能正確拿到IP
shell> pon vvpn
message顯示信息：

接著看ifconfig ppp0的信息, TX狂漲，2分鐘內到1.3G... 汗，這個是不可能的，接著就自動斷掉了，message log如下：

這個問題怎麼解決？附加配置文件
/etc/ppp/peers/vvpn:
pty "pptp 121.x.xx.xx --nolaunchpppd"
name shns
remotename pptpd
require-mppe-128
file /etc/ppp/options.pptp
ipparam connect
/etc/ppp/options.pptp:
lock
noauth
nobsdcomp
nodeflate
/etc/ppp/chap-secrets:
"ns" pptpd "123456" *
請問是什麼原因啊？在線等，比較急，謝謝

忘記說了，系統是 CentOS 5
《解決方案》
檢查連接到vpn伺服器的機器，看是否存在大量發包的程序
《解決方案》
你重新安裝一個ppp-2.4.3試一下.
另外你也可以用bwm這個工具查看流量是否確實大.

沒有的，流量肯定是假的，問題是我應該怎麼解決，2個centos 5試過都是這個情況

伺服器很乾凈的，沒什麼特別的程序在跑的

vpn伺服器 從 windows撥過去是正常的，沒人遇到過這個問題嗎？暈
