asciilifeform: but tells him to go to hell because ping.

asciilifeform: actually it very often meets a , e.g., version message: version 70002, blocks=454102

asciilifeform: mircea_popescu: nope. it simply hasn't heard a block in ~2 hrs.

asciilifeform: my concern is not that there is a boojum in 454074. but that the thin red line connecting my trb nodez to miners are -- apparently -- veeeery thin

asciilifeform: BingoBoingo: that is long past my wedgepoint

asciilifeform: sigops ?

asciilifeform: then which

asciilifeform: mircea_popescu: nah, e.g., 454047, was larger.

asciilifeform: aah

asciilifeform: BingoBoingo ? jurov ?

asciilifeform: does anybody have 454074 on a spitblock-capable node ?

asciilifeform: wanted to examine 454074.

asciilifeform: it is why i asked after mimisbrunnr

asciilifeform: both of mine, are

asciilifeform: for hours nao.

asciilifeform: in other wtf's, banning pings took dulap from 50+ to 7 peers (1 of which is zoolag), and none of'em seem to know of any block past 454073

asciilifeform: lel yes, just as described

asciilifeform: phf's logger swallows without burping ☟︎

asciilifeform: now crapolade

asciilifeform: what changed ?

asciilifeform: now the correct

asciilifeform: holyfuck i am seeing '
ACTION' in '<mircea_popescu>
ACTION has seen this time'... but http://btcbase.org/log sees the correct line

asciilifeform: 'mouse in evacuated jar dies' 'sauce?'

asciilifeform: mircea_popescu: same

asciilifeform: which had to enlarge chairs, train ceilings, whole shebang, in 1960s

asciilifeform: ben_vulpes: best documented example is the japanese subway

asciilifeform: see also http://btcbase.org/log/2015-11-08#1319688 ☝︎

asciilifeform: aite

asciilifeform: mimisbrunnr.cascadianhacker.com down??

asciilifeform: didjaknow.

asciilifeform: 'the world pointed out'

asciilifeform: as they currently 'help' in cp cases.

asciilifeform: and if the bits are not the right bits -- they can 'help'.

asciilifeform: hey if bits-on-a-disk-in-police-custody can count as 'evidence' of anything else -- why not this.

asciilifeform: in other lulzies, https://archive.is/Bwz53 >> 'Now, if a suspect receives drugs by post — which he denies he ordered — the police can go over his bitcoin transaction history and see whether he has sent bitcoins to anyone recently.'

asciilifeform: in other noose, as discussed earlier ( http://btcbase.org/log/2016-12-05#1577994 ) >> https://archive.is/AVO23 << autodesk bought and destroyed 'eagle', the only fully functioning pcb cad for linux. ☝︎☟︎

asciilifeform: in other lelz, 'The White House repeatedly refused to mention Jews in its Holocaust remembrance, and had the audacity to take offense when the world pointed out the ramifications of Holocaust denial.' ☟︎

asciilifeform: (given as i generate a tx perhaps yearly)

asciilifeform: other folx ( particularly mircea_popescu ) may also be interested in tx propagation, but i am unequipped to test this.

asciilifeform: i have listed the imho most interesting, above.

asciilifeform: and a number of other conundrums, that really ought not to be conundrums this far in.

asciilifeform: is there a consistent set of peers who 'prank call' (dial and won't speak) ?

asciilifeform: what portion of network bandwidth is taken up by crapola ?

asciilifeform: to continue: what portion of cpu time is spent verifying ultimately invalid blocks?

asciilifeform: but yes, for instance.

asciilifeform: ben_vulpes: getaddr

asciilifeform: or, what portion of mempool actually makes it into blocks

asciilifeform: or, what portion of tx are valid, and what portion -- obvious nonsense

asciilifeform: or, how much time does trb node spend rejecting crapolade from same idiots again and again

asciilifeform: e.g., do new valid blocks come 'from everywhere', or consistently from a few places.

asciilifeform: and also to answer several other itching questions of mine

asciilifeform: ben_vulpes: this is a slow-burning project of mine in its own right -- to determine what the fuck EXACTLY these things are doing, when they go 'blackhole'

asciilifeform: (it is very much a manual, batched process.)

asciilifeform: ben_vulpes: i'll answer this when i eat the current pcap

asciilifeform: (they, like other nonsense, get malleus'd)

asciilifeform: ProcessMessage(alert, 168 bytes) FAILED << lel, somebody still sending these

asciilifeform: BingoBoingo, jurov , and anybody else still running old prb nodes for whatever reasons of their own -- note that you will no longer be able to connect to dulap. (or to zoolag, when i patch it. or to anybody else who includes this patch.)

asciilifeform: and, recall, single-threaded idiocy

asciilifeform: btw dulap will appear to be blackholed from pov of everybody else, for probably hour or more, as it is catching up with blocks

asciilifeform: in re 'if you won't talk to prb, you won't hear from miners' thing.

asciilifeform: kako can put this in his pipe, and smoke it.

asciilifeform: i will now also confirm that a goodbye-pingers node still receives blocks.

asciilifeform: dulap now operating with 'goodbye, pingers'.

asciilifeform: http://therealbitcoin.org/ml/btc-dev/2017-February/000248.html

asciilifeform: ACHTUNG, PANZERS!

asciilifeform: something that was sent to it, much earlier, gums up the works

asciilifeform: the other interesting tidbit is that a blackhole node is often spoken to (by would-be peers) but never once speaks

asciilifeform: entirely possible

asciilifeform: 68.10.122.122 for instance.

asciilifeform: single message containing 3,4,5 pings !

asciilifeform: for instance, some nodes send 'multipings',

asciilifeform: found quite a few wtf

asciilifeform: to revisit upstack, i set up tcpdump on blackholed dulap and recorded

asciilifeform not familiar

asciilifeform: whatthehell is 'prbnet' if not the swamp of prb nodes.

asciilifeform: it is possible to remove'em, trivially. this will result in banning 'pingers' and a hard break with prbnet.

asciilifeform: in the sense that i left lines 2097..2099 live, when introduced 'malleus'

asciilifeform: trinque: as a matter of fact, no: http://btc.yt/lxr/satoshi/source/src/main.cpp?v=asciilifeform_add_verifyall_option#2097 << it was grandfathered in

asciilifeform: could simply add anybody who emits a 'ping' to banlist. ☟︎

asciilifeform: we could.

asciilifeform: eventually he disconnects, but does not add us to his ban list, and so the process repeats, ad infinitum.

asciilifeform: doing nothing and occupying socket.

asciilifeform: he doesn't get a 'pong' back, and so sits there like idiot

asciilifeform: enough of these, and you get one type of blackhole.

asciilifeform: because ~he~ 1) sits on the socket + 2) won't talk

asciilifeform: but what this results in is a deadweight peer

asciilifeform: well we also right now discard the pings.

asciilifeform: did it 'pong' back ? or drop'em ? or wat.

asciilifeform: btw mircea_popescu's old node declared 60000 compatibility. so it probably gets same treatment from prb peers

asciilifeform: link plox?

asciilifeform: did we?!

asciilifeform: box falls behind, loses peers, begins to sink into classical blackhole behaviour (as it gets dropped by everybody, including fellow trb nodes)

asciilifeform: this soaks up precious single-threaded sockets...

asciilifeform: so they see trb set to, e.g., 99999 (as mine, for instance, are) and goes ping,ping,ping,motherfucker,ping,ping,whywontchapong

asciilifeform: http://btc.yt/lxr/satoshi/source/src/main.cpp?v=0.6.1rc1#2691 << prb 0.6.1rc1 introduced a 'heartbeat' mechanism, where a prb node seeing ver. > 60000 ( see http://btc.yt/lxr/satoshi/source/src/version.h?v=0.6.1rc1#0045 ) sends 'pings' and expects back 'pong'

asciilifeform: sooooooo.... ACHTUNG, PANZERS! i found ~one~ heretofore-undiscovered cause of black hole:

asciilifeform: massive brutalist box in formerly empty space near washington monument

asciilifeform: mircea_popescu: they did, they called it 'museum of african american history'

asciilifeform: https://archive.is/4WtAT << goes with previous. mr.t is being set up as '“The President’s sudden acknowledgement is a Band-Aid on the cancer of anti-Semitism that has infected his own administration,” Steven Goldstein, executive director of the Anne Frank Center ...'
