ubuntu 13.10 中 pppd 的日志在哪里？

Question

我正在尝试在 Ubuntu 13.10 上查找 pppd 的调试信息。我尝试阅读手册，但发现日志的位置适用于旧版本的 Ubuntu。

我有输入

sudo pon dsl-provider debug

Answer 1

您可以在 /var/log/syslog 中看到 pppd 日志

less /var/log/syslog

或者

tail -f /var/log/syslog

或者

cat /var/log/syslog

Answer 2

来自 pppd 手册页：

   debug  Enables  connection  debugging  facilities.   If  this option is
          given, pppd will log the contents of all control packets sent or
          received  in  a  readable  form.  The packets are logged through
          syslog with facility daemon and level debug.   This  information
          can  be  directed  to  a  file  by  setting  up /etc/syslog.conf
          appropriately (see syslog.conf(5)).

因此默认情况下所有pppd日志都将重定向到/var/log/syslog。
