T1 Circuit actual throughput 1290Kbps
by tonyh＠noc.cbn.net.id 13 Jul '98

13 Jul '98

Does anybody have experience having a T1 circuit with PPP encapsulation getting only 1290 Kbps maximum throughput looking at "sh int" result from cisco router or MRTG ? This is the explanation our upstream provider gave us: You have a 1.536Mbps port. However, there is the overhead from PPP and the translation overhead which takes place in all circuits. Judging by your settings that limit ends up somewhere between 1.3 and 1.4. This overhead would be the non-data portion of cells or frames for example. For example, you might have 1.3 Mbps of data which gets framing or cell information appended onto it before sending taking up additional bandwidth. It is to be expected in all circuits. Thank you for your help. Tony S. Hariman http://www.tsh.or.id Tel: +62(21)574-2488 tonyha(a)compuserve.com

Smurf Prevention
by Richard Thomas 12 Jul '98

12 Jul '98

Perhaps we might have some success preventing smurfs from the most common sources, hacked machines on university dorm networks, by getting the university backbones to filter spoofs. Things like SUnet, FUnet, NYSERnet, etc, account for a large portion of universities used to smurf from, and it might be easier then trying to get each school to filter individually. I found the following two addresses for nysernet and funet but was unable to read or translate the Swedish on www.sunet.se.

Except, of course, that the Registration Agreement that a domain registrant agrees to in order to get a domain says that the domain can be deleted for false information.

But...OOOPPSS!...the information in WhoIs is phoney, and we don't >do anything about that. Sorry, guess you're just screwed. There are many other ways to track a spammer. - Do nslookup on the IP that originated the spam (sometimes this takes a bit of detective work to find what IP actually originated the spam). - Traceroute to the originating IP. Email the ISP that is directly upstream. - Look in the Whois information for contact emails and nameservers - if these are for the upstream ISP, or some ISP other than the spammer, report it to them. - If they are advertising a web page, track the web page host, and their upstream, and report it to them. - If the spammer is stupid enough to use their real names, include their phone numbers and addresses in the complaint. Or call them up yourself and tell them what you think. Order pizzas with triple anchovies and pineapple, and no cheese. Order 50 pink flamingos on their front lawn, with a sign saying "Congratulations on your graduation from kindergarten !!" :) The above few lines *were* in jest. I probably would not include the sign. :) >What do spammers and nails have in common? They're both intended for >hammering.

Actually I was thinking of a combination of 'order wires' with a combination of VSAT and in-band network conference bridges for backup. However several people of indicated that level of backup was too expensive. This problem isn't really unique to the Internet. I was looking at the backup communications network for SS7 providers and noticed a couple of major SS7 network providers don't give out their direct contact information even to other SS7 network operators anymore. They changed their listings in the emergency directory to general customer service numbers. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation

It was located in Building 6 on the 4th floor I think in E-aisle. Building 6 is the newer building behind the original collection of buildings at the corner of Naperville Rd. and Warrenville Rd. ihnp4 replaced ihnss. ihnss was one of the last large PDP 11/70s purchased at Indian Hill in Naperville in the late 1970s. I should know, I handled the SPA budget for it, and ordered it. It was a difficult decision not to buy a VAX at the time. We had to go with the proven PDP 11 because the VAX UNIX software was not stable enough when the orders were placed. We did research using ihnss. Phil Karn was new to Bell Labs and I encouraged him to take over ihnss when I left that location...I have not seen Phil since...when I returned to Indian Hill, ihnp4 was there...and Phil was gone...I assume that Phil somewhere along the line Phil convinced someone to convert it to a VAX...I suppose the increase in traffic was one of the reasons... I hope this helps to answer your questions about ihnp4 and also some of your questions about my association with AT&T... Jim Fleming Unir Corporation - http://www.unir.com

Zebra homepage?

In Kunihiro Ishiguro's NANOG presentation it mentions a Zebra homepage of http://zebra.digital-magic.co.jp/ which appears to be unknown to DNS (at least to mine) as do all obvious permutations. Zebra also seems absent from their web page. Anyone know of a newer Zebra resource?
