Did someone at Merit see my posts and decide to start mirroring the ARIN RR (see the source line at the bottom)?

OK barge-bridge collision and collapse
by Sean Donelan 26 May '02

26 May '02

A few people asked the interstate-40 bridge collapse in Oklahoma across the Arkansas river. 11 and possible as many as 20 people are believed dead. Although I-40 is a major cross-country interstate, the bridge collapse had no apparent impact on cross-country telecommunications traffic. I'm not aware of any fiber routes across that bridge.

Selective DNS replies
by Avleen Vig 26 May '02

26 May '02

This subject has probably been talked to death, so I apologise in advance for bringing it up! Is there any DNS server currently availible that can reply to DNS lookups based on the source IP address? Yes, this would be for directing users to a 'local' server hosting www.example.org (or something similar). Yes, this is not the best way of doing it I know :-) I was wondering if there was something available that DID this yet. Thanks. -- Avleen Vig Work Time: Unix Systems Administrator Play Time: Network Security Officer Smurf Amplifier Finding Executive: http://www.ircnetops.org/smurf

Re: Certification or College degrees?
by Nigel Clarke 26 May '02

26 May '02

IMO: Certifications are a waste of time. You'd be better off obtaining a Computer Science degree and focusing on the core technologies. Why would you devote your career to learning a vendor's command line or IOS? Cisco has done an excellent job @ brainwashing the IT community. The have (unfortunately) set the standard for "Network Engineers". What do you think is more respected, a masters degree in Networking Engineering or a CCIE. In most circles it would be the latter. Cisco's certification program has effected the entire IT community. Their CCIE's are required to recertify every few years, thus forcing them to stay true to the Cisco lifestyle. I've met some CCIE's who don't know any programming languages or any experience with Unix. It's clear that they are one dimensional and unfocused. Why study the same thing over and over? Do you really have X amount of years experience, or do you have 1 years experience X times? Think about it. If you have been in the field for over 5 years and someone new to the industry by way of certification can handle your work load, that is a serious problem. If anything certs should be used as a stepping stone or advancement to new technologies or areas. Then again, the question of CERTS vs. DEGREES might apply differently to someone without any experience. I guess it really depends on what your looking for. --- Nigel Clarke Network Security Engineer nigel(a)forever-networks.com

The Cidr Report

This is an auto-generated mail on Fri May 24 23:00:00 PDT 2002 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. Check http://www.employees.org/~tbates/cidr-report.html for a daily update of this report. NEW: Check http://www.employees.org/~tbates/cidr-report-region.html for the regional version of this report. NEW: Check http://www.employees.org/~tbates/autnums.html for a complete list of autonomous system number to name mappings as used by the CIDR-Report. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to GX Networks for giving me access to their routing tables once a day. Please send any comments about this report directly to CIDR Report <cidr-report(a)cisco.com>. ------------------------------------------------------------------------------ CIDR REPORT for 24May02 0) General Status Table History ------------- Date Prefixes 170502 109785 180502 109834 190502 109804 200502 109906 210502 109923 220502 109973 230502 109965 240502 110020 Check http://www.employees.org/~tbates/cidr.plot.html for a plot of the table history.

Slightly Operational: How to 0wn the Internet in Your Spare Time
by Sean Donelan 24 May '02

24 May '02

Although this thread will immediately go out of control, Vern Paxson et al once again has come up with some interesting numbers. Something to read over the US Memorial Day holiday weekend. http://www.icir.org/vern/papers/cdc-usenix-sec02/index.html I was lucky enough to see a preview of the paper. It shows we still have some hard work ahead of us.

Actually (without hoping to trigger a flame war), there are a lot of very large comanies, mainly in the US (mainly in the finanial sector or eduction sector, and occassionaly in the defense sector), who DO refuse to hire without a degree. There are many good technical persons out there who don't have a degree. There are almost many unemployeed technical persons who would make better admins / engineers than some people I know who have degrees. With the current situation, I see the following: Proportionally here are more technical people in jobs WITH degrees than without People with degrees have more experience, and get farther I believe the latter reason is because more people hire candidates with degrees. Vicious circle. Not hiring people who don't hold degrees is fast becoming a policy matter. The reasons for it are numerous. Very few (IMO) are 'good' reasons.
