OT: New software mag (free download)
by Jeffrey Race 18 Mar '05

18 Mar '05

>From another list. While aimed at open-source users and developers, this new magazine publishes some very interesting articles of general interest to all computer users. Original post: --------------------------------------------------------------- Hello, Tony Mobily, along with a few amazing hackers and lay people, have started a new magazine called "Free Software Magazine". Here is the URL: http://www.freesoftwaremagazine.com. The great thing about this magazine is that all of the articles are released under a free license six weeks after publication. They count on making money on paper and PDF subscribers, who get the magazine before anybody else does. So far their plan seems to be working (110 subscribers in the first month), but they definitely need a lot more than that to even break even. The magazine is half-technical - quite literally! The first half of the magazine contains technical articles, while the second half concentrates on the ethics, legalities and philosophies of free software and its use. Each issue also has a "focus", with several articles covering a particular area in greater depth. The magazine is $4.95 per issue (monthly), and you can also get six monthly and yearly subscriptions at lower rates. If you want to write for Free Software Magazine, please let us know. We are also offering free advertising for free software projects. Bye, --------------------------------------------------------------- Thanks! Tony Mobily Editor-In-Chief Free Software Magazine http://www.freesoftwaremagazine.com

Failures and hot-potato routing
by András Császár (IJ/ETH) 17 Mar '05

17 Mar '05

Hi! Does anyone have any statistical data how often intra-domain link failures cause that a new edge router is used? E.g., if the path between the original ingress-egress routers has a higher IGP cost after an IGP SPF calculation due to a link failure. Cheers, András http://www.tmit.bme.hu/~csaszar

Because he does not have the entire /16 you can't > just delegate like that. OK, what am I missing? *ASSUMPTION*: The holder of the /16 _has_ delegated rDNS for the 32 /24s to the /19 owner. The /19 owner can, on it's nameserver, run an "authoritative" zone for the /16 -- with _its_ /24s listed explicitly, and a wildcard pointing back to the rDNS nameserver of the /16 owner. "He who" queries from the outside world will work their way down from the .arpa zone, to the X.W.in-addr.arpa zone, get referred to the nameserver at "thiscompany", and get referred to the NS listed for Y.X.W.in-addr.arpa. which will resolve Z.Y.X.W.in-addr.arpa. "He who" queries the /19 owner nameserver directly for a Y.X.W.in-addr.arpa address that lies within the /19 owner's addresses will get answered by that nameserver, *or* be referred to the client's server. If they ask for something *outside* the /19 owner's space, the wildcard -- referring to the 'upstream' (the /16 owner) nameserver kicks in. _AS_LONG_AS_ the 'delegated to' nameserver has the wildcard in it pointing back to the 'parent' nameserver, this seems to work just fine. Admittedly, if the upstream block owner changes the _name_ of it's nameserver(s), the 'delegated to' nameserver requires manual tweaking, but, realistically, "how often" does _that_ happen?

And that is correct. Both are referring you to another zone. The set of servers in the first belong to 209/8, the latter to 209.173.48/8. What is not apparent is that neither query is resulting in an answer. Instead, the reply is a "go ask someone else" referral. It's like Joe says "ask Bob" and Bob says "ask Charlie." -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Edward Lewis +1-571-434-5468 NeuStar Achieving total enlightenment has taught me that ignorance is bliss.

I really doubt that he participates in the NORTH AMERICAN network operators group. SORBS -- like _any_ other blocklist -- is simply an expression of opinion. if you feel that "somebody" is 'wrongly' blocking mail because of a SORBS listing, your _first_ step should be to contact *that* party, and request that either (a) they stop using SORBS, or (b) that they 'whitelist' you. *THEY* are the ones that made the decision to block your mail to their system. Contact means for SORBS *is* provided on the web-site. it works reliably. Be advised, however, that a 'need' on your part does not translate to urgency on the part of anyone else. Note: *Nobody*, not even SORBS, says you 'have to' make that charitable contribution. All the 'spam' listings _do_ "age off" the SORBS system, eventually. Caveat: I have nothing to do with SORBS. I don't use it -- or *any* blocklist, for that matter -- myself (I use other means that are better suited for _my_ requirements). I don't even know the operator thereof. Everything I've said is based on published and publicly available information.
