Truncated logs aren't so helpful. This tells us nothing about what's going on. > It seems echo requests come more often towards the end, almost every > second.

By default, pppd won't send these, but will respond if the other side sends them. The idea is that if you send a request, and the other side fails to respond, then, regardless of what the hardware is telling you, the link itself is dead, and can be torn down. However, in the exchange you've shown here, every request has a response, and all of the requests and responses appear to be in good order (each side is attaching its own LCP magic number option, which is the right thing to see, and the ID numbers line up for request/reply). There's nothing out of what you've sent that indicates (to me, at least) any sort of problem, at least within PPP itself. -- James Carlson 42.703N 71.076W <carlsonj@xxxxxxxxxxxxxxx>
