test DNS that returns SERVFAIL? ... ! :-)
by Michael Paoli 19 Apr '20

19 Apr '20

test DNS that returns SERVFAIL? ... ! :-) For when one may want a target DNS domain to test against that will generally return SERVFAIL ... I didn't super easily find one out there, so ... (at least for now) created one. ... on the master (IPs for the MNAME in SOA are on this host) $ hostname balug-sf-lug-v2.balug.org $ dig +noall +answer +multiline balug.org. SOA | awk '{if(NR==1)print $5;}' ns0.balug.org. $ dig +short ns0.balug.org. A ns0.balug.org. AAAA 96.86.170.229 2001:470:1f05:19e::2 $ ip a s | egrep 'inet.*(96\.86\.170\.229|2001:470:1f05:19e::2)' inet 96.86.170.229/29 brd 96.86.170.231 scope global eth0 inet6 2001:470:1f05:19e::2/64 scope global $ So, add RR: # nsupdate -l << \. update add servfail.balug.org. 300 IN NS servfail.balug.org. send . # Ah yes, I'm quite starting to get used to and like/prefer dynamic DNS update. Significantly more goof-resistant, and most of the time I don't even have to think about the zone serial number. Which reminds me, I do still want to add some version "control" (tracking) ... driven via cron, so I'll at least have periodic snapshots of changes (since no longer using ye olde manual method & manual version control). For more recent changes, and fine-grained history of changes, logs cover that quite well. But for the longer historical record ... wee bit 'o gap presently to fill on that. Automation is generally a good thing. :-) And with no other (explicit - some DNSSEC automagic bits may be added but we'll ignore those presently) RRs for that domain. So, we then typically get, e.g.: $ dig +noall +answer +comments servfail.balug.org. ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 26642 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 $ Note that not all flavors of query against servfail.balug.org. will return SERVFAIL: $ dig +noall +norecurse +answer +authority +comments @ns0.balug.org. servfail.balug.org. ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 20976 ;; flags: qr; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; AUTHORITY SECTION: servfail.balug.org. 300 IN NS servfail.balug.org. $ But in general, trying to do a recursive query on the domain for most RR types, will give SERVFAIL. (Useful for testing, ...)

A better Linux event to drop by to in SF, IMHO, is SF-LUG's actual first-Sunday-of-the-month meeting. Also, and not at all to scare you off, while its extremely unlikely that this will _in any way whatsoever_ affect Tuesday evening's BALUG dinner at Henry's Hunan Restaurant should you decide to attend it anyway -- with the restaurant's delicious and reasonably priced Hunan chicken dishes -- there _have_ been reports by Chinese authorities within just the last two weeks or so confirming a highly pathogenic strain of the H5N1 bird flu in Henry's Hunan province. "Hunan is about 400 km south of Hubei province that has the city of Wuhan, which is the epicentre of coronavirus." (https://theprint.in/health/coronavirus-hit-china-now-reports-h5n1-outbreak-… ) FYI, an excellent web-resource for 95percent-plus Linux events is Rick Moen's Bay Area Linux Events site http://linuxmafia.com/bale/ (the one notable not-just-Linux-or-FOSS exception might be Rick's relatively recent listings for Tom's Berkeley Pi Meeting group http://linuxmafia.com/bale/#berkeleypi) Besides SF-LUG's once-a-month meeting, I'd suggest your also looking into some of the outlier locations for their bona fide _Linux_ end-user support and feedback for those relatively new to installing + using Linux, e.g., BerkeleyLUG, the Diablo Valley Linux User Group (DVLUG), the East Bay Linux User Group (EBLUG), and maybe one or two other regional Linux User Groups. -----

10 types
by Rick Moen 16 Oct '19

16 Oct '19

At yesterday's BALUG meeting, someone hauled out an old chestnut: There are 10 types of people in this world, those who understand binary and those who don't. -- Unknown I mentioned that there were a couple of responses to that, that I had converted to .signature files. The first was by a poster named Ron Fabre on the Linux Users of Victoria (Melbourne) mailing list (whose comment I .sigged): -- Cheers, There are 10 kinds of people in the world, those who Rick Moen know ternary, those who don't, and those who are now rick(a)linuxmafia.com looking for their dictionaries. -- Ron Fabre McQ! (4x80) Being also on that mailing list, I couldn't help doing meta-commentary: -- Cheers, There are 10 types of people in this world, those who know quaternary, Rick Moen those who only recently figured out Ron Fabre's "ternary" .sig, those who're completely confused, and those who hate self-referential jokes. I also like: There are two kinds of people in the world: Those who can extrapolate from incomplete data and There are 10 kinds of people in the world: those who understand hexadecimal and f the rest. and Q. Why do mathematicians confuse Halloween and Christmas? A. Because 31 Oct = 25 Dec.

Richard M. Stallman has resigned from FSF and from MIT CSAIL
by Rick Moen 20 Sep '19

20 Sep '19

tl;dr: https://www.fsf.org/news/richard-m-stallman-resigns In the wake of the Jeffrey Epstein matter, controvery arose about dealings between him and the (also now-late) MIT AI scientist Marvin Minsky, and about MIT administration actions related to Epstein. Richard M. Stallman is intimately associated with not just the Free Software Foundation (that he created) but with MIT CSAIL (Computer Science and Artificial Intelligence Laboratory) operation. Fairly recently, there was a discussion on one of CSAIL's unadvertised and privately archived mailing lists, csail-related, where Stallman posted comments.[1] Those comments (mostly about matters peripheral to the late Dr. Minsky) became known to MIT alumna, grad student, and mechanical engineer Selam Jie Gano, who is said to have been sent them by a subscriber. Ms. Gano was very incensed by Stallman's views that she asserted were, among other things, 'defending Epstein'. She publishes an essay on Medium entitled 'Remove Richard Stallman. And everyone else horrible in tech': https://medium.com/@selamie/remove-richard-stallman-fec6ec210794 She also provided what is asserted to be the entire thread to Vice.com's regular 'Motherboard' feature, which published a rather inaccurate piece based largely on her allegations, though providing a curated copy of the mailing list thread with all participant names except Stallman's blacked out. Article: https://www.vice.com/en_us/article/9ke3ke/famed-computer-scientist-richard-… Direct link to Vice.com/Motherboard's curated thread copy: https://www.documentcloud.org/documents/6405929-09132019142056-0001.html?em… Quite a number of other outfits have picked up the story in various ways. Stallman responded by objecting (with perfect justification, as far as I can see) that in no way was he defending Epstein; that this is just not at all what he said. The persons now running Software Freedom Conservancy took advantage of this squalor by 'calling for' Richard to retire from the free software organisation & movement he created (unsigned because they have _that_ little moral backbone). https://sfconservancy.org/news/2019/sep/16/rms-does-not-speak-for-us/ There was also pressure for Richard to resign from his position at CSAIL (where ISTR he's been Visiting Professor). He has now done so, citing 'pressure on MIT' -- along with resigning as President and Board of Directors member at Free Software Foundation. IMO, this affair (e.g., things like the unsigned editorial from the jackals at Software Freedom Conservancy) has opportunism written all over it. One of the less-sucky bits of news/analysis (apparently just before things came to a head) was here: https://fudzilla.com/news/49393-stallman-defends-himself-over-epstein-comme… https://lwn.net/ have not yet caught up with events, and can be expected as usual to be guarded to a fault when they do. https://lists.gnu.org/archive/html/libreplanet-discuss/ has some discussion, but likewise has not caught up with events. [1] None of what I'm writing here imply endorsement of Richard's assertions in the mailing list thread, by the way. In fact, I very much do not concur with some, and would have, among other things, politely corrected his factually incorrect understanding of the legal concept of 'assault'. -- Cheers, Views expressed are my own.

Quoting Michael Paoli (Michael.Paoli(a)cal.berkeley.edu): >o At this meeting - we'll have a someone with 20 years experience using > and doing systems administration of Debian. Hey, I've been administering Debian since 2.1 'slink', as well, so that makes two decades for me, too. (The Official Debian installer was rather dreadful, then, and the replacement d-i installer introduced with 'sarge' (3.1) is miles better. https://wiki.debian.org/DebianInstaller > >o Debian Birthday ("born" 2019-08-16) / Debian @ 25 / Debian Day / > > Debian Appreciation Day I see that 'Debian Day' aka 'Debian Appreciation Day' is the anniversary of when the late Ian Murdock founded the project on 1993-08-16. Personally, I would want to count from the release date of the first public beta, v. 0.90, on 1994-01-26.

BerkeleyLUG meetup Sunday 2018-11-11
by Rick Moen 12 Nov '18

12 Nov '18

A posting quoted below has just been retroactively removed from BerkeleyLUG's Google Group archive by LUG original founder Jack Deslippe, who was kind enough to so inform me of that action (for which my genuine thanks). His cited reason: 'I think it uses unnecessary language in places when describing the individual'. I of course respect Jack's right to make decisions for that Google Group. In my view, this account of events today used _absolutely necessary_ language describing the individual and his actions (and in alluding to similar actions at many prior meetings). I posted it in public _specifically_ because repeated attempts to privately fix this problem failed and instead it worsened -- and specifically to create a public record. Thus this re-post: to un-disappear my comments. (Views expressed are my own.) ----- Forwarded message from Rick Moen <rick(a)linuxmafia.com> ----- Date: Sun, 11 Nov 2018 14:28:34 -0800 From: Rick Moen <rick(a)linuxmafia.com> To: BerkeleyLUG <berkeleylug(a)googlegroups.com> Subject: Re: AC Power, Wi-Fi but not from venue itself: Re: BerkeleyLUG meetup this Sunday 2018-11-11 12Noon STANDARD Time at 85C Bakery Quoting Michael Paoli (Michael.Paoli(a)cal.berkeley.edu): > Have had 4 of us here so far ... But also, now, two fewer, following the latest round of John Regan aka Giovanni aka whatever-it-is-this-week misconduct right there, today, at the BerkeleyLUG table. I've had a near-contemporaneous account of what happened. Sadly, I had a conflicting obligation in Milpitas, otherwise I most certainly would have brought a screeching halt to this nonsense. Honestly, hasn't John wrecked enough BerkeleyLUG meetings already, or do y'all intend to keep just sitting there and only reacting long after the fact, and with little or no consequence? What I heard happening was: John Regan walked in and saw three women sitting at the table BerkeleyLUG traditionally uses. He started hassling the women and telling them they had to move because this is a reserved table. Michael Paoli reminded John that no, this is not a reserved table and never is one, nor are any of the others downstairs. John ignored Michael, continued to give the women a hard time, and advised them that he was finding them another table. Kim Davalos spoke up to reiterate what Michael P. said, that _no_, this is not a reserved table. John told the women that they should ignore Kim because she arrived late. After being thus browbeaten, the women finally got up and moved elsewhere. After the fact, 85c Bakery management confirmed exactly what Michael and Kim had said, and were informed of the repeatedly and continually misbehaving person who evidently needs stronger social control so he can no longer run amok at BerkeleyLUG. Arrangements were made with the manager in the future for them to step in sooner the next time this person cannot behave in a civilised fashion to require him to immediately leave. Today's incident, like many of the others John has inflicted on BerkeleyLUG this year, are in my view simply disgraceful and should be curbed instantly rather than indulged. Already, the _immediate_ result of today's incident was that two regulars, disgusted with the failure to enforce obvious standards of acceptable behaviour, walked out and went elsewhere. I've privately warned after past incidents that permitting this clown to run amok at BerkeleyLUG is quite likely to destroy the group if proper corrective action is not taken. Today, I'm reiterating that warning publicly. You already know what to do. End this. Next time, stop sitting on your tochises, get up, and do it. Seriously, people, this isn't even difficult to figure out. (See also .signature.) -- Cheers, "I am a member of a civilization (IAAMOAC). Step back Rick Moen from anger.
