> Its capable of high bandwidth 120-180Mb/s with out problems. Thats not high bandwidth and I actually meant to really say, large volumes of small packets which I've seen a number of OS's fail at very low bandwidths [number of contexts etc]. The issues with routes is much simpler to fix with kernel adjustments :-) Regards, Neil.

NetScout RMON probe opinions, other recommendations?
by rise 06 Dec '01

06 Dec '01

I'm looking for experiences with and opinions on NetScout's line of RMON probes (WAN & ATM both) or the Cisco resold versions. Currently in place are a set of legacy Visual Networks probes (ASE) and precisely what real added value the NetScouts provide is in question. It's been suggested that NetScout service may not be satisfactory so any experiences pro or con on that would also be most welcome. I can keep provided information confidential (limited to the purchasing manager and I) if requested and I'll be happy to summarize the other responses back to NANOG if there's enough response to make it useful. Recommendations of competing RMON probe manufacturers would also be very useful since the dubious claim has been made that "all the others went out of business during the crunch"... -- Thanks, Jonathan Conway rise(a)knavery.net

Extended Communities
by Susan Hares 05 Dec '01

05 Dec '01

nanog-ites: I need some input from the Operator community on the use of Extended communities in BGP. I would like to know how many people: - originate a technology that uses extended communities, - pass through BGP packets with Extended communities, and - block packets with Extended communities. I would like to leave the discussion of the operator use of the extended communities on the NANOG list as I think it may be useful to keep in the archive. If you don't want to comment publically, please also send me a note privately (skh(a)nexthop.com) If you want to chat at me, my phone's list. Also, people are welcome to comment on the specification to me (skh(a)nexthop.com) I will summarize comments on the Extended Community specification to the list. Thanks for the input, Sue Hares (co-chair idr) skh(a)nexthop.com (734)222-1610

BellSouth

Does anyone have any contact information for BellSouth? They've been rejecting mail from our mail servers, and I can't seem to get a hold of their support -- one of the contact numbers on the page doesn't work in Canada (888-321-2375), and I got hung up on twice when calling the other number (800-436-8638).

Any else seeing an attack by Inktomi originating from Exodus address space? I have had an average of 5 queries per second for over a day to one specific web site. I have them blocked at the router but they keep trying. Email to Inktomi doesn't seem to help. Roy Engehausen
