An ISP I support has FreeBSD servers and a bunch of LAN- and ISDN-connected clients. Its remote so I can't get to it physically. In the past couple days, the 256Kbps link has been totally saturated, MRTG tells me it's outbound traffic. How can I determine which system is causing the traffic? I'm not a Cisco expert, but hoped "show ip accounting" would help, but it only appears to show me *inbound* traffic from all outside addresses to my internal addresses. I need the opposite. Is there some IOS command I'm just not clued into? I'm working with the remote admin to see if I can get a hub put between the router and other ISP gear, then put a FreeBSD box on that so I can use tcpdump or others to sniff the traffic. Until then, I'm blind unless there's some cisco voodoo I can use. Any ideas? Thanks. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
