RE: SWIP and Rwhois in the Real World

Can someone summarize the alternatives to the ARIN recommended RWHOIS server bits (from rwhois.org)? A quick hit on Google and Freshmeat was fairly barren. Looking for one that is mostly or fully put together, or a cookbook to assemble one from parts (i.e. MySQL, PHP, Apache, 3 rubber bands, 2 gallons of perl, etc...).

I do not proclaim myself to be an engineer and try to stick with what I do well. I read rfc, wikipedia, etc but just don't know what /to/ read. I had never heard of iBGP, OSPF, IS-IS untill today. What I need, and I'm sure quite a few others who listen to this list for insight, is a good reference to pick up and read that will cover said topics and beyond. I finally got the basic concept to CIDRs and how they work thanks to this list and Google. I know this message is slightly off topic from NANOG, but kinda fits in response to parent and am hoping not to get flamed. Any suggestions? A Padawan, Mark Owen

It's worth noting that C's don't need actual IP address space assigned to the router-id for OSPF. It's just an arbitrary value; it's probably better karma to set it to whatever you want (maybe something that doesn't look like an IP address). RFC 2328: Router ID A 32-bit number assigned to each router running the OSPF protocol. This number uniquely identifies the router within an Autonomous System. CCO: <http://www.cisco.com/en/US/products/sw/iosswrel/ps1839/products_command_ref…> Usage Guidelines You can configure an arbitrary value in the IP address format for each router. However, each router ID must be unique. If this command is used on an OSPF router process which is already active (has neighbors), the new router-ID is used at the next reload or at a manual OSPF process restart. To manually restart the OSPF process, use the clear ip ospf command.

[Pr-plan] Public-Root resolution problems and UNIDT (fwd)
by Peter Dambier 30 Sep '05

30 Sep '05

Statement of the Official Public-Root Representative September 29, 2005 This communication is published on the Internet at URL: http://www.cynikal.net/~baptista/P-R/2005-09-29%20Memo%20to%20the%20Interne… Memo to the Internet Community Public-Root resolution problems I in my capacity as the Official Public-Root Representative and whistle-blower, asked Peter Dambier to publish to NANOG a notice that the Public-Root had fractured. Namely, the root in Ankara operated by Celep Bahadir who is also the UNIDT (www.unidt.com) representative to Turkey and the Middle East. There was an attempt by UNIDT to start a new root system called the United-Root. Attempts by Ankara to test this root on l.public-root.net at 195.214.191.125 resulted in a fracturing of the public-root network. The Ankara root injected a number of older records into the DNS resulting in false answers to queries. Ankara was also listing as root servers some DNS that pointed back to ICANN data and did not resolve the Public-Root. This was very unprofessional behavior on behalf of UNIDT resulting in a serious violation of their contractual obligations to the Public-Root. I sent several email communications to UNIDT General Manager Mr. Marty van Veluw pointing out the problem. I am pleased to announce the problem is corrected now but no official response was received back from Mr. Van Veluw. The last time Ankara was checked it was found the root server is out of sync with the remaining Public-Root network. This is also very unprofessional. I have sent email messages to Mr. van Veluw pointing out the problem. Unfortunately I consider UNIDT unstable and expect they may intentionally jeopardize the root in order to break their contracts with us. Mr. Martijn Burger the chair of INAIC and Public-Root has advised me Mr. van Veluw may close down the Ankara server in the near future. This would also constitute a violation of the contract between UNIDT and the Public-Root. I continue to maintain my position that any administrator using the public-root should select another root system during this period of reorganization. I also want to take this time to criticize NANOG (North American Network Operators Group) and the inclusive and alternative namespace communities. However, my main concern is NANOG. I find the fact the people of Turkey are being the subject of technical jokes on NANOG appalling. Anyone who understands the importance of root servers also understands the fiduciary responsibilities that go with such an operation. The technical problems with the public-root pale when one reviews the people involved. I regret to say that hackers and criminals are behind the Public-Root. Therefore, this is not a joke, this is a serious issue. The people of Turkey and Tiscali users have been surfing the Internet using a system that can compromise their security and privacy. I hope in future the NANOG and root communities will be more responsive and civil. - 33 - Joe Baptista, Official Public-Root Representative and Lobbyist to the United States Congress and Senate / Tel: +1 (202) 517-1593 Public-Root Disclosure Documents: http://www.cynikal.net/~baptista/P-R/ Public-Root Discussion Forum: http://lair.lionpost.net/mailman/listinfo/pr-plan

[eng/rtg] changing loopbacks
by Randy Bush 30 Sep '05

30 Sep '05

so i have junipers, ciscos, and a few <gasp> zebras in an ospf and ibgp mesh. they're peering via loopbacks, of course. unfortunately, i need to recover the space from which the loopbacks are taken. of course, i would like to do so with minimal disruption. i am thinking of something like the following: o add second loopbacks to all routers with new address in new block o set up ibgp peerings to new addresses from existing peerings o change the source of routing updates to new addresses o remove old peerings o remove old loopbacks what [else] am i missing? randy

Weird DNS issues for domains
by Matthew Crocker 30 Sep '05

30 Sep '05

I'm hoping someone on the list can help confirm that I'm not going insane. I have a customer with the domain 'mtrsd.k12.ma.us' The domain should be handled by our DNS servers (dns-auth1.crocker.com & dns- auth2.crocker.com) The customer has an A record for www.mtrsd.k12.ma.us pointing to their web server The customer has subdomains for each school in the district which have www records pointing to their web server via CNAME Everything looks like it is configured properly on my servers but the customer is reporting that certain parents (VerizonDSL, Comcast, DirectWAY) can connect to certain website and not others. At this point I think the problem is with the DNS servers at their ISP. Can someone confirm my sanity? My zone of control starts at mtrsd.k12.ma.us I do not have control over k12.ma.us What do you all see for sanderson.mtrsd.k12.ma.us & www.sanderson.mtrsd.k12.ma.us. ; <<>> DiG 9.2.2 <<>> @204.97.12.2 mtrsd.k12.ma.us NS ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 522 ;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;mtrsd.k12.ma.us.
