Hello, I have a misconfigured postfix installation, I inherited. Does anybody know of anyone who would consider reconfiguring/fixing it. It seems that all mail presented to it appears to be from "localhost", when i reject unautorized destinations, it rejects all mail. Thanks in advance. Bill Kruchas

OSPF convergence - WAN links
by Rafael Ganascim 17 Dec '10

17 Dec '10

Hi all, I have a network with a lot of FastEthernet WAN connections (some metro-ethernet), and using the OSPF as IGP. Today, the OSPF timers are the defaults (hello 10s, dead 40s, SPF initial timer 5s, etc). When a link comes down, the convergence time takes ~45s (ok, it's right). There are a lot of documents explaining about tuning OSPF convergence time, but on LAN environments. I didn't find any references about this OSPF tuning on WAN ethernet links (just serial, frame-relay, etc) and things related to it (such as packet loss, rtt, 'never lost of carrier', etc). I think that, if the timers are aggressive, any flap on the ISP network can cause a re-convergence... if the timers are high, the convergence time on down links is high too. What factors are you considering when tuning this OSPF timers on this type of link? What 'tecnologies' are you using (such as Fast Hellos, incremental SPF, etc) ? Thanks, Rafael

OT - NO (Non-Operational) Question
by Joe Blanchard 17 Dec '10

Happy holidays to all. Quick question with regard "Text/SMS" messaging. I know this is not really the place to ask, so forgive me for bending your eyes. It appears there's really no easy way to determine the origin of a text sent to a cell, at least as far as I can see without involving the provider(611) Any quick links/ideas as to where to research this? Perhaps something obvious I missing? And yes, I tried, lmgtfy.com (: Thanks in advance, and happy holidays/Xmas/New years to all, -Joe Blanchard

Re: Some truth about Comcast - WikiLeaks style

Earlier this morning a Comcast peering manager had the following things to say about the recent NANOG thread, in a public IRC channel with many witnesses: my management is pretty disgusted with the badmouthing and accusation slinging on nanog.org btw the demands to disclose confidential data on the blog aren't helping either the budget for hosting will be impacted I guarantee because it came out of folks who are being hassled's budget there is a meeting today to discuss the value of supporting the NANOG community Apparently Comcast's support and sponsorship of NANOG has actually been a ploy to buy our silence, and if we keep talking poorly of them they're going to cut off the funding. Shhhhh don't tell anyone.

It would certainly serve to make customers angry. They have a choice of video provider netflix vs hulu, but only one isp. In this case the customer drops netflix in an angry huff and goes to hulu. That customer is gone forever. ------Original Message------ From: Patrick Giagnocavo To: nanog(a)nanog.org Subject: Re: Some truth about Comcast - WikiLeaks style Sent: Dec 16, 2010 11:05 AM On 12/16/2010 10:54 AM, Mikel Waxler wrote: > But in that scheme, Comcast looses in the long run, when the FCC gets around > to them, but Netflix looses customers immediately. > > " I pay Netflix 10$ a month and they wont let me use their service cause I > am on Comcast?

Alleged backdoor in OpenBSD's IPSEC implementation.
by Wil Schultz 15 Dec '10

http://thread.gmane.org/gmane.os.openbsd.tech/22557 This appears to be some serious FUD, but if true could have some serious implications for IPSEC stacks in all kinds of equipment. -wil
