pptp+freeradius的vpn，xp自帶的vpn撥號程序只能用pap明文口令驗證，求教！
用windows xp自身的vpn撥號建立連接，只有在連接的「屬性」－>「安全」－>「高級」里設定唯一的「不加密的密碼pap」才能正確登錄，其他spap、eap、chap、mschap、mschap v2都不能登錄，而且radius的debug模式下，這幾種加密方式都有提示：
Login incorrect: (from client localhost port 0 cli 10.217.0.1)
radius的用戶用的是/etc/raddb/users配置文件的方式：
myuser Auth-Type := Local, User-Password == "abc123"
其中Auth-Type指定維MSCHAP也依然是這樣
請各位大蝦指導小弟
這個是options.pptpd的配置

我不熟悉，期待其他熱心網友來解答你的問題
《解決方案》
急切盼望有哪位大蝦能幫忙指導啊，也謝謝版主
《解決方案》
怎麼會沒有mppe
# Require MPPE 128-bit encryption
# (note that MPPE requires the use of MSCHAP-V2 during authentication)
require-mppe-128
《解決方案》
加上了這個：
# Require MPPE 128-bit encryption
# (note that MPPE requires the use of MSCHAP-V2 during authentication)
require-mppe-128

還是老樣子，只要我吧vpn撥號指定使用非明文pap的，radius.log裡面就會有這樣的記錄：
Login incorrect: (from client localhost port 0 cli 10.217.0.1)
對應的/var/log/messages裡面：
Mar 1 16:10:41 sina pptpd: CTRL: Client 10.217.15.177 control connection started
Mar 1 16:10:41 sina pptpd: CTRL: Starting call (launching pppd, opening GRE)

不用radius，pptpd能夠加密連接嗎？千萬不要是你的內核不支持mppe。
《解決方案》
直接用pptp可以mppe加密認證通過，在chap-secrets里配置的
《解決方案》
lsmod結果里也包含mppe模塊：
ppp_deflate 5953 0
zlib_deflate 20825 1 ppp_deflate
ppp_mppe 13824 0
ppp_async 12353 0
crc_ccitt 2241 1 ppp_async
ppp_generic 34708 3 ppp_deflate,ppp_mppe,ppp_async
《解決方案》
require-mppe-128是傳輸的數據加密
pptp只能使用名文或ntpassword(微軟nt密碼)
《解決方案》
小弟希望用pptp＋radius認證的時候，xp客戶端撥號能用mschap-v2的方式進行認證，懇請大家幫忙
