The dial up lines are on a different class C network. What is happening is an arp entry is lost for a portmaster after a period of inactivity (normal). We have been relying on redirects from our router (which is a FreeBSD box) to restablish routes to the dialup lines via a portmaster (rip and ospf are partially broken on our portmasters). I can ping the dialup line, and get a redirect from the router on every single packet, even though an arp entry for the portmaster and route for the dialup ip get restablished on the first packet. The response times for the pings are horrible (over 1 second). I can kill ping, run it again, and thinks are ok (responses around a couple of milliseconds). Occasionally, during the night a user dials up and ftp's a sizable file from a server that has been quiet for a while, and it just kills our network. We're in the process of revamping the network to separate portmasters from servers at which point it'll cease to be a problem, it's just puzzleing. Is there a lot of overhead associated with generating redirects on a FreeBSD box? - Barrett Richardson rabtter@aye.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
