ppp-watch - Man Page

ppp-watch interface-name [boot]

ppp-watch manages one PPP connection, including starting, stopping, and redialing. It makes starting and stopping the connection synchronous activities.

ppp-watch is not really meant to be called directly.  It should only be used from within the ifup-ppp script.

interface-name

The name of the PPP interface to bring up.

boot

ppp-watch is being called at boot time and should time out after a while if the PPP connection does not come up in order not to hang the boot sequence.
