linux pptp 619

用pptp做了个vpn,以前做都是正常,配制文都是copy现在正常运行的服务器的配制,不知道为什么出现619.

我在/etc/ppp/options.pptpd 中加了logfile /var/log/pptpd.log
可是为什么没有生成log文件呀。

还有一台也是,配制完后,正常运行了,一周。也出现619.
看/var/log/pptpd.log内容最近的都是Modem hangup.没有其他内容。
救命呀。

5月1日,凌晨,在这个劳动节的早上,重装了N次之后,偶尔删除了,/var/log/pptpd.log。故障竟然恢复了。
百思不得解。一个日志文件,怎么可以会影响到。
我的options.pptpd中的logfile /var/log/pptpd.log这个的原因吗?
我是新手,不明白,是什么,感觉应该是生成日志吧。
望有高手解惑。
