[Nanog] Anyone know how I can contact uky.edu abuse?
by Jake Matthews 22 Apr '08

I've tried from 4-5 different mail providers to send something to abuse(a)uky.edu. Can't figure out what's wrong, as I've never seen AuthRequired anywhere before. Every single one of them has gotten the reply of: *Delivery has failed to these recipients or distribution lists:* abuselist(a)email.uky.edu <mailto:abuselist@email.uky.edu> Your message wasn't delivered because of security policies.

Re: [Nanog] Cogent Router dropping packets
by Mike Fedyk 22 Apr '08

22 Apr '08

(Crossed Fingers) Cogent's network seems "OK", for now. I've received several responses asking for details on how I would avoid Cogent. It looks like getting a connection to the AT&T network will allow us to serve our customers on their DSLS and use their direct peering to the Time Warner network for our customers with cable Internet. If anyone has any ideas on how this will work, please let me know. For instance, do most networks prefer to keep packets on their network until closest to the end point or might a network just send the traffic through cogent in another part of their network a few hops away? -----Original Message----- From: Mike Fedyk Sent: Thursday, April 17, 2008 2:59 PM To: nanog(a)merit.edu Subject: RE: Cogent Router dropping packets I spoke too soon: Host Loss% Snt Last Avg Best Wrst StDev 1. adsl-63-194-XXX-XXX.dsl.lsan03.pacbell.net 0.0% 109 9.2 19.2 8.4 57.9 11.0 2. dist3-vlan60.irvnca.sbcglobal.net 0.9% 109 8.4 16.7 8.3 45.6 9.6 3. bb1-p6-7.emhril.ameritech.net 0.0% 109 8.6 36.3 8.5 256.6 44.2 4. ex2-p14-0.eqlaca.sbcglobal.net 0.0% 109 10.3 39.4 9.3 209.3 46.2 5. te8-1.mpd01.lax05.atlas.cogentco.com 0.0% 108 32.4 34.3 9.3 238.6 45.1 6. vl3491.ccr02.lax01.atlas.cogentco.com 3.7% 108 17.0 23.4 12.9 98.9 13.4 7. te3-4.ccr01.lax04.atlas.cogentco.com 17.6% 108 39.1 28.8 16.4 198.9 22.1 8. vl3805.na21.b002695-2.lax04.atlas.cogentco.com 12.0% 108 34.1 27.6 17.0 68.7 11.2 9.

> So why would anyone plug an ATSC feed directly into the Internet? Because we can. One day ISPs might do multicast and it might become cheap enough to deliver to the home. If we don't then they probably will never bother fixing those two problems I've been multicasting the BBCs channels in the UK since 2004. The full rate are mostly used by NOCs with our news on their projectors, we have lower rate h264, WM and Real for people testing multicast over current ADSL. The aim is by 2012 to be able to do all our Olympics sports in HD (a channel per simultaneous event rather than the usual just one with highlights of each) something we can't do on DTT (= ATSC) due to lack of spectrum (there's enough but it's being sold for non TV use after analogue switch off) > Are there any devices that can play it other than a TV set?

But that day is long gone. Evidence is a lot of people still like to vegetate in front of a tv rather than hunt their content.

Sure but P2P isn't a requirement for that and currently saves you no money (UK ADSL wholesale model) over unicast. If people are taking random content you won't be able to predict and send it in advance. If you can predict then you can multicast it and save some transport cost vs P2P/unicast > Better yet, the ISP's P2P manager could arrange > for one full copy of that file to get across the congested peering > circuit during > the time period most favorable for that single circuit, then distribute > elsewhere.

[Nanog] REDUSE LEASE PERIOD
by Felix Bako 22 Apr '08

22 Apr '08

Hi Guyz We have a cisco PDSN that acts as a NAS for our Wireless BroadBand Clients. The PDSN tackles the IP alllocation Part. This is because we have defined the ips to be allocated using the IP LOCAL POOL command. Is there a way to reduce the lease period of the allocated IPs.

Everyone agrees having more data would be useful.
