Procedure如何从 pppd 获取诊断信息

以下过程说明如何在本地计算机上查看链路的当前操作。

  1. 成为本地计算机的超级用户或承担等效角色。

    角色包含授权和具有一定权限的命令。有关角色的更多信息，请参见《系统管理指南：安全性服务》中的“配置 RBAC（任务列表）”。有关如何使用主管理员配置文件配置角色，请参见《系统管理指南：基本管理》中的第 2  章 “使用 Solaris Management Console（任务）”。

  2. 将为 PPP 配置的串行设备作为参数，运行 pppd：


    # pppd cua/b debug updetach

    以下示例说明了当 pppd 在前台运行时，生成的拨号链路和租用线路链路显示内容。如果在后台运行 pppd debug，生成的输出将发送到 /etc/ppp/connect-errors 文件。

示例 21–1 正常运行的拨号链路的输出


# pppd /dev/cua/b debug updetach

have route to 0.0.0.0/0.0.0.0 via 172.21.0.4

serial speed set to 230400 bps

Using interface sppp0

Connect: sppp0 <--> /dev/cua/b
