Is it common practice for ISPs to rate limit UDP, Multicast and ICMP on a customer connection to reduce the effects of various DOS attacks? On the backbone? TIA, Thomas

BGP Route Damping
by German Martinez 13 Nov '01

13 Nov '01

Good Day, Perhaps this document was already discussed (I'm new in this list). If it was please let me know. Basically, I wanted to get an opinion from US based ISP about this document. Does somebody know how Tier-1 networks implement route damping ? Here is the document: http://www.ripe.net/docs/ripe-210.html Thank you for your comments ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * THE DILBERT FUTURE * * Thriving on Stupidity in the 21st Century * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "Internet capacity will increase indefinitely to keep up with the egos of the people using it"

Hello, > Does you have any idea why routers at Colt still see the old announce? > People at Colt have no idea. Abovenet checked on its side and sees > only the good prefix. Who in COLT did you email? Nothing came in via noc(a)colt.net regarding this. We saw this route from a peer that was announcing us a huge number of routes that for some reason max-prefix didn't prevent from happening, although after rebooting, the box did take the session down. My guess is that the routes announced to us had sometype of corruption that didn't send it through the max-prefix subroutine properly to detect the number of routes being advertised.

No word on what the glitch was, or if it involved a human.

ISIS Monitoring & Visualisation Requirements
by Matt Duggan 13 Nov '01

13 Nov '01

Hi, I am currently doing some research into the monitoring and visualisation requirements for networks running ISIS. I am primarily interested in what you feel are the key requirements for monitoring and viewing ISIS within a network and why? (I guess it would include stuff like Adjacency and DR changes & area, mesh group, DR visualisation etc). If you could let me know your thoughts that would be most useful. regards, Matt. -------------- Matthew Duggan, World Data Systems Ltd. mailto:matt.duggan@world-data-systems.com www: http://www.world-data-systems.com -------------- This e-mail including any attachments is confidential and may be legally privileged.

Network operation security forums
by Sean Donelan 13 Nov '01

13 Nov '01

With the ICANN meeting opening this week, and the unusual focus on network security, I assume most network operators have been deluged with Internet security questions from all sources. The public discussions I know about have focused on "popular" subjects such as root servers, ddos, viruses. While interesting, and challanging topics, are they really the biggest security problems facing Internet operators? I don't think so. But that's just my opinion. Where are Internet operators discussing the common risks they all have? What are the biggest security risks Internet operaters need to manage? I'm concerned about route integrity, multi-provider facility risks, and multi-provider restoration deadlock. Why do I worry about them, because they are risks no single provider can manage alone.

DNS Host Handles/Registrations
by measl＠mfn.org 13 Nov '01

13 Nov '01

Good afternoon! This may sound like a dumb question, but... The last time I registered a DNS host it was still being done by NetSol/InterNIC (yeah, a *long* time ago). I need to add another DNS host, and cannot seem to find the appropriate place to do this. InterNIC.net, ICANN, IANA all come up blank. Anybody out there done one of these recently? Thanks! -- Yours, J.A. Terranson sysadmin(a)mfn.org If Governments really want us to behave like civilized human beings, they should give serious consideration towards setting a better example: Ruling by force, rather than consensus; the unrestrained application of unjust laws (which the victim-populations were never allowed input on in the first place); the State policy of justice only for the rich and elected; the intentional abuse and occassionally destruction of entire populations merely to distract an already apathetic and numb electorate... This type of demogoguery must surely wipe out the fascist United States as surely as it wiped out the fascist Union of Soviet Socialist Republics. The views expressed here are mine, and NOT those of my employers, associates, or others. Besides, if it *were* the opinion of all of those people, I doubt there would be a problem to bitch about in the first place... --------------------------------------------------------------------
