It definitely sounds like the T1 is saturating --- but it would never hurt to more-positively document that. If you can get router statistics on line utilization that would help. Given that they're using up the T1, one good question is, do they want to buy more bandwidth? If so then by all means do so. But people doing big downloads can saturate _anything_ (I know --- I like to do tricks like mirror the entire Red Hat site:-). So if other users are noticing degraded response, I'd look into bandwidth management solutions. Cisco has some traffic shaping options for recent IOS releases, there's dummynet[1] (for FreeBSD --- freely available) and the Bandwidth Manager[2] (for FreeBSD, BSDI, and NetBSD, $500). And worst comes to worst, you may well be able to do the deed if you force the big downloaders to go through a separate set of proxies, and put a mechanism in place --- e.g. a slip line running at 115kbps --- to throttle their bandwidth. -Bennett [1] <URL:http://www.iet.unipi.it/~luigi/ip_dummynet/> [2] <URL:http://www.etinc.com/bwmgr.htm>
