The next task shows how to use the pppd command to obtain debugging information.
You only need to perform step 1 through step 3 once for each host. Thereafter, you can proceed to step 4 to turn on debugging for the host.
Create a log file to hold output from pppd.
% touch /var/log/pppdebug |
Add the following syslog facilities for pppd in /etc/syslog.conf.
daemon.debug;local2.debug /var/log/pppdebug |
Restart syslogd.
% pkill -HUP -x syslogd |
Turn on debugging for calls to a particular peer by using the following syntax of pppd.
% pppd debug call peer-name |
peer-name must be the name of a file in the /etc/ppp/peers directory.
View the contents of the log file.
% tail -f /var/log/pppdebug |
For an example of a log file, see Example 31–3.
