So, it will wait up to 300 seconds when no traffic is sent, then it will bring the line down. If you set the timeout to 0, it won't timeout ever. (But, it also won't re-dial the line if it does down for other reasons, such as phone line problems, etc...) > then background ping to isp to ensure connection This will work to make sure the line is always up, but it wastes bandwidth that could be used for real work. > If the line is up does ppp try to dial on outgoing packets?? Nope, because the line is up. > if the line is down will ppp dial ?? Yep. > Does timeout mean redial after n secs of no packets ? Yep. > whats a good blend to ensure line is up most of the time?? Use my 'ddial' patches to ppp (I posted them last week, check the archives), use pppd in a busy loop, or use the ping method above. Nate
