The following procedure shows how to view the current operation of a link on the local system.
For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.4.
# pppd cua/b debug updetach
The following examples show the resulting displays for a dial-up link and a leased-line link when pppd runs in the foreground. If you run pppd debug in the background, the output that is produced is sent to the /etc/ppp/connect-errors file.
