/etc/ppp/Autostart
All outbound PPP connections are started through the user-generated
/etc/ppp/Autostart file. When the local system is booted, a pppd
process is started for the outbound link to the remote system. There is no
example Autostart file; you must create it. It contains the command
line necessary to start pppd:
pppd local_host:remote_host daemon_mgt_opt link_mgt_opt idle_timer
Refer to the pppd(1) man page for information on command line
options.
In our example, here is the Autostart entry on robin for connecting to
lark:
pppd robin:lark auto idle 150
The pppd started here has this connection configuration:
Local and remote hosts: robin and lark, respectively
Daemon mgmt. option: Auto (respond to the arrival of a
packet by initiating a connection to
peer).
Link management option: Idle (idle timer in effect).
