I connect to the Internet through a phone line on which I run kernel ppp. My IP address is dynamically assigned every time I call my ISP. Simple as it sounds, from time to time packets stop coming in through the modem. I can see how packets still go out, but they never get a reply from outside. It seems this happens whenever (but not always ) I spawn a lot of http transactions in a very short time, say pages with lots of frames and images or maybe accessing several hosts at a time. Not so often the problem appears also in the middle of a lengthy http download (a single big document and nothing else ). I have run tcpdump on the ppp0 interface and it only confirms what can be deduced from the modem lights, to the best of my understanding. The link never seems to recover from this state; the only fix up to now has been hanging and dialing up again, after what everything works as it should. So can anybody make sense of this ? What steps may I take in order to find the culprit ? TIA Manuel Garcia To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
