I am testing a FreeBSD-4.0 stable machine as a firewall, and have a reasonably complex ipfw ruleset that probably does invoke some stateful rules. ssh and telnet sessions to this box appear to go into a stalled state, where there is a 30sec pause before they re-awake and respond to user input. pinging the interface can wake them up again, which is why I suspect its something in the ipfw engine. now clearly, for a box which is shuffling bits frequently this wouldn't be a problem because there'd be enough through-traffic to keep things ticking over. am I mis-diagnosing things? is this also visible as a side-effect of apm or other stuff? what else apart from ipfw/state can make connects to a box hang if idle for more than a few minutes? cheers -George To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
