Fluke LAN Mapshot is a nice one-trick pony product for mapping L2 switches. Point it at a network, give it the right snmp community strings, and it generates a switch topology.

The RADB is only a part of the IRR. Many larger ISPs and NSPs run their own registries and there are several international registries including APNIC and RIPE. There has been at least one free database out there. I just don't remember the URL. (It's in the archives, but the search may be painful.) I strongly approve of such requirement. I know that it is in the peering agreements of several carriers, but they often don't check or enforce this. Many register customer routes and ASes. If routes and policies were properly registered, securing the Internet would be a lot closer to being possible. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.

Network discovery and mapping
by Sean Donelan 23 Jun '03

23 Jun '03

Its been a few years since I looked at network discovery and mapping tools. Openview/et al did the job, but was always a pain to move all the boxes to the right spots on the resulting maps. Has network discovery and mapping improved for medium-scale wide area networks for ISPs (e.g. 1,000 networks, 100,000 network devices)? I've found lots of discovery tools, but intelligent mapping/layout still seems to be a problem. The usual requirements for SNMP smart discovery, interface/subnet mapping, device identification and connecting the right symbols with the right lines to all the other symbols.

BTinternet problems?
by Mike 23 Jun '03

23 Jun '03

We're receiving multiple complaints about problems reaching anything @bt. Is anyone else experiencing this? I.E. e-mails to @btopenworld and also @btinternet.com are bouncing. The root cause seems that we are unable to resolve anything within bt.com et al. For whatever reason, this is affecting all of the netblocks that we have nameservers in, but not some others we control.

Not sure how relevent this may be but: Interland has recently been in a major network move.... They boight out Communitech and are in the process of moving datacenters to the Interland centers.. This could explain it.... But they should be doing a better job of it though...

OT: question re. the Volume of unwanted email (fwd)
by Miles Fidelman 22 Jun '03

22 Jun '03

Hi Folks, Someone on the cybertelecom list raised a question about the real costs of handling spam (see below) in terms of computer resources, transmission, etc. This dovetailed a discussion I had recently with several former BBN colleagues - where someone pointed out that email is not a very high percentage of total internet traffic, compared to all the multimedia and video floating around these days. Since a lot of the arguments about spam hinge on the various costs it imposes on ISPs, it seems like it would be a good thing to get a handle on quantitative data. It occurs to me that a lot of people on this list might have that sort of quantitative data - so... any comments? Regards, Miles Fidelman ---------- Forwarded message ---------- Date: Wed, 18 Jun 2003 09:15:08 -0400 From: Timothy Denton <tim(a)TMDENTON.COM> Reply-To: Telecom Regulation & the Internet <CYBERTELECOM-L(a)LISTSERV.AOL.COM> To: CYBERTELECOM-L(a)LISTSERV.AOL.COM Subject: Issue: the Volume of unwanted email Cybertelecomers: I want the advice and knowledge of people on this list. I dared not use the word spam lest I be filtered out, but the issue is the economic cost of spam for ISPs. There has been much to-do about spam of late. Figures from Canarie show that SMTP transmissions account for about .5% of the volume of Internet traffic. This may be typical of backbone networks, or not. Commercial networks are jealous of revealing information of this nature. ISPs report that spam is now about 46% of email, and that it adds to the cost of transmissions because of the extra machines that have to be bought and operated. Question: What is the economic cost of handling all this spam, in terms of additional boxes, software, transmission costs etc? I am aware that spam adds large costs in terms of time and attention at the user end. Is there evidence of what it adds in terms of hardware and software? As we head toward legislative remedies in the US and Canada, I would like to have a better idea of the economic impact of spam.

Spam and "following the money"
by Joe St Sauver 22 Jun '03

22 Jun '03

Hi, Whenever the topic of spam comes up, the suggest always arises that people "follow the money" to track the spammers. Sometimes, it is true, that will be useful, but it takes a rather naive approach to the spammer's business model. In many cases, spammers don't actually need to *deliver a product or service* to the person they are spamvertising to make money from sending spam. Some spammers make their money via banner advertising revenues: if they can get you to visit one of their pages (even an "unsubscribe" page), they can get "hits" for some advertising program and make money from you. Or consider pump-and-dump stock tout spam... no direct product or service needs to be delivered to a spammee for the spammer to make money, assuming he can use spam to run the stock price up and the SEC doesn't jump on traders with unusual purchase and sale patterns. In some cases, the spammer's scheme is outright fraud: one of the reasons that penis enlargement spam (or spam for Viagra or other "embarassing"-to- purchase products) is so common is that spammers are counting on people being too embarassed to admit that they (a) fell for a scam, and (b) that they were dumb enough to send cash to some PO Box in Romania, and (c) that they needed the particular product that was being spamvertised in the first place. Likewise spam for pay-per-view cable descramblers/theft of service devices and other illegal/semi-illegal products: if your pay-per-view theft of service cable descrambler provider fails to deliver a functioning theft-of-service device for your use, who are you going to complain to, the police? It is also worth noting that in many cases people are providing their name, credit credit number, and expiration date to some random server hosted somewhere in China, hmm, whaddya think, any possibility of fraud taking place? I could make fifty bucks selling some fake human growth hormone, or thousands charging stuff on a steady stream of live credit card numbers. If I had to point at the most common way to make money from spam these days, I'd bet on credit card fishing... But even routine credit card fraud pails in comparison to the costs associated with trying to regain your financial identity after it has been completely co-opted following provision of complete financial details to some "mortgage referral specialist..." And then there are the pr0n "dialer" dudes, who offer "free" access to their pr0n site, you "just" need to use their special software (which calls a 900 number somewhere in the Caribean for $15.00/minute, and/or sends more spam for them). Lastly, there are plenty of spam service providers who make money from selling email addresses, selling spam software, selling spam hosting services, you name it... in fact, some of the largest American carriers are *perfectly* willing to provide connectivity for spamvertised web sites so long as the spam doesn't actually get sent from that connectivity (and with hundreds of thousands of open proxies out there, well, there's no need for a spammer to be that gauche!) If you want to stop spam, take the time to see where spamvertised web sites are being hosted, and who's providing transit for those hosts. I've been doing this for a while now, and I can *definitely* see some pretty obvious patterns. I guess those transpacific OC3s and OC12s for "strategic" customers are just too lucrative to risk jeopardizing with trifles like enforcing terms of service... Regards, Joe

This report has been generated at Fri Jun 20 21:46:50 2003 AEST. The report analyses the BGP Routing Table of an AS4637 (Reach) router and generates a report on aggregation potential within the table. Check http://www.cidr-report.org/as4637 for a current version of this report.
