ppp-watch — daemon to make PPP interfaces act more like other interfaces
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.
The name of the PPP interface to bring up.
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.
