Looking for someone who is very experienced with IPForwarding in Extreme switches
by Drew Weaver 11 Feb '04

I figured I wouldn't bore the rest of you with this slight oddity I've come across in ExtremeWare that I am having an issue getting resolved, but if anyone knows a decent deal about how these switches really work, and doesn't mind giving me a hand, could you tag me off list? Thanks, -Drew

As I told you in another email, a good 40% of my mail on my personal colo comes from sources without rDNS - mostly within India, from and to some fairly large linux lists. regards -suresh

Root Servers Request
by Donovan Hill 10 Feb '04

10 Feb '04

This is a formal request to ICANN that they hand over the root server to a not-for-profit organization. I nominate ISC for this task. -- Donovan Hill Electronics Engineering Technologist, CCNA www.lazyeyez.net, www.gwsn.com

After all the filters that I use were applied - 682 unique IP addresses, with no rDNS sent at least 6124 legitimate (assumed legitimate as not caught by my filters) emails in the period from Feb 2 to Feb 10. This box hosts mail for two large linux lists. And hosts my email, and email for my parents and a few friends. I and my friends are subscribed to various local linux and other mailing lists - several of which have no rDNS. srs

Trust me, the error rates on sites would vary widely, especially because you cannot assume a standard / uniform population of people sending mail to these sites. People who mail IETF lists, and people in asia, sending mail to a local list server in the rDNS-less desert that is some parts of APNIC land, might have completely different perceptions on the issue. Now, from your logs, just how much legitimate mail do you get that comes from an IP without PTR RR, and how much is that expressed as a percentage of legitimate incoming mail to your lists? How much is that as a percentage of spam inbound to your list [to be fair, let's make it "spam that would not have been stopped by your other filters]? srs

> So, how do you explain that NIC France accepts the use of linux.fr > to someone who pretends to be the author & proprietary of > the name "linux" and who IS NOT Linus Torvalds? This reminds me of the times when people on the list accused other list members of being closet spammers. At the end of the day, this kind of public accusation is a waste of our time because we don't really have the tools to determine which side is telling the truth. In this case, I am fluent in French, and I spent 15 minutes or so, browsing http://www.linux.fr. It appears to be a legitimate *public* portal for people who are promoting the use of Linux in the enterprise. Nothing on that site claims authorship of Linux and I even stumbled across one forum message that made it clear that Linux is based on the GNU toolset. What is clear is that both http://www.linux.fr and you http://www.fr.scguild.com are trying to offer directories of IT consultants among other things. Could it be that you would rather divert the common resource (a domain name) for your own profit rather than let someone else do the same? Hopefully you and AFNIC http://www.nic.fr can take this silly dispute offline where it belongs.

>> We need to start with an Email Service Consortium with a code of email >> server practices in which the larger ISPs agree to stop accepting SMTP >> connections from anyone who is not in the consortium or a customer. This >> will get everyone implementing a set of well-known and consistent controls. >...is not practical. Remember the true street-level definition of spam: >"spam is e-mail you didn't want that wasn't sent by me or my customers." >Trying to form an E-S-C under those conditions is unthinkable or useless. That's why I maintain that we should not be trying to solve the man-in-the-street's SPAM problem. ISPs can't do that. But ISP's could join together into a consortium to solve the serious weaknesses in the overall Internet email service architecture that allow SPAM to thrive. Once the architecture has been fixed, spammers will find it hard to do joe-jobs or to send spam anonymously. When it is easier to identify the actual sender of a spam message, then ISPs will find it much easier to enforce their AUPs on abuse. --Michael Dillon

Does anyone have any pointers for me. Something that fills the >organizations needs and that will work with Eudora? Hmmm... If you go to http://www.eudora.com/techsupport/tutorials/esp/ it says this: Create an ESP Group and subscribe your work email address and your home email address. Make a change to your calendar at home - and the changes will be synchronized with your calendar at work! Presumably this means that it will synchronize the standard iCal files used by products like Mozilla Calendar and Apple's OS X iCalendar. A quick bit of googling shows several universities are using Eudora in conjunction with a calendaring program called Meeting Maker. --Michael Dillon

Need some info on network management
by Savitha Kumar 10 Feb '04

10 Feb '04

Hi, I am a Post Graduate student from India and network management is my area of interest. I have been browsing through the net on different network management tools available in the market. In all of them, accounting management which is one of the FCAPS functionality is not supported on any of the NMS's. So I thought it would make sense if I contact a network operations group regarding this. Can you please throw some light on the following - 1. Why is "accounting" not part of most of the NMS's? 2. What do service providers use for billing their customers? It would be great if you could help me on this. Thanks a lot for your valuable time!
