http://logs.nosuchlabs.com/log/asciilifeform/2020-03-01#1008171 <<< not in some time, the !w peers cmd jogged my memory and made me remember that. Might be interesting to pull some prb ip's from trb debug.log and see what it returns.

11:33

shinohai: see yest.'s log re coupla example of prb

11:33

( they returned 'empty' on 'peers' )

11:34

in fact, this is a reliable heuristic for prbism

11:39

e.g.

11:42

Returns loads of ipv6 nodes xD

11:42

!w peers 187.115.249.96

11:42

187.115.249.96:8333 :

11:42

interesting. evidently it breaks protocol (i.e. trb's traditional one) somewhere, and gets hung up before emitting any parseable peers to 'watchglass'

11:43

(this means trb won't get peers from node of that type either)

11:43

For ref, here is the script nmap uses (lua) https://svn.nmap.org/nmap/scripts/bitcoin-getaddr.nse

11:44

^ doesn't tell us much, seems to call some lib function that does it

11:46

trb incidentally doesn't eat ipv6ism (nor ought to, wtf)

11:51

shinohai: here is what apparently happens with these.

11:52

Hmmm .... "Invalid payload length!"

11:52

it's always the same one, too

11:52

somewhere prb puts an extra byte, i suspect

11:53

( which frame-shifts the contents of header )

11:54

for comparison, debugola from a proper noad (.27) which successfully disgorges peers.

11:55

possible culprit, but there may be other idjicies in prb that give similar effect.

↖

11:57

the other oddity, tho, is that -- while trb sends addr packet almost immediately after receiving getaddr, prb apparently not

11:58

shinohai: how long did that nmap thing take to produce the given output from that noad?

11:58

nm seems to say '20.04s' in there

11:58

Ye old bloom filtering

11:58

so, loox like just past the point where watchglass gets hung up

11:59

shinohai: watchglass simply ignores packets it has nfi what to do with (presently parses ver and addr strictly)

12:01

shinohai: my interest in this whole thing is to eventually map out all publicly-networked trb-compat. noades. but this might require being able to get peers from prbistic ones.

12:04

prolly will have to be a 2-step algo (i.e. try trb protocol, if 'empty' -- then mark noad as 'defo prb' and try theirs)

12:04

For any spelunkers tuned in, here is list of all ip's seen in my debug.log thus far: http://btc.info.gf/paste/165b3b@raw

one could say that peers who don't appear on such a listing, are strictly 'downstream', i.e. being connected to'em does nothing for you

12:11

It's only ~week old, stood up to help mod6 do patch tests, etc. so only has abt 250k blox

shinohai would like to ship box to asciilifeform and stand up permanent node.

shinohai: for another comparison, 'givers' from a 14GB debuglog from my other, older noad .

shinohai: this btw confirmed. i did experiment, if one sends that extra byte, prb noades do in fact send addrs. (and yes some of'em ipv6, have to be thrown out)

↖ ↖ ↖ ↖ ↖ ↖ ↖

14:38

Logged on 2020-03-01 11:55:32 asciilifeform: possible culprit, but there may be other idjicies in prb that give similar effect.

14:38

so that there's how to get addrs from prb's.

14:38

( notably, this procedure is incompat. w/ trb, these will hang up if it is done to'em )

14:41

interestingly, setting advertised ver. of watchglass to 70000 -- dun cure (tho per 'official' docs, oughta)

14:42

evidently the conditionality of the extra turd byte is ignored in current-day prb

14:42

( which would explain why folx who set their trb to advertise 7xxxx do not see perceptibly moar peers )

14:42

the 'watchglass' currently hanging in this chan (and #asciilifeform-test ) is set to 99999 .

14:48

In effect, appears to be attempt to fork noads off network that are deemed terrorist. xD

14:49

shinohai: prolly the intended effect. tho funnily enuff, prb still often does connect to trb nodes, and even brings blox. cuz apparently a validly-digested ver msg is optional in prb...

14:49

what it doesn't do, is bring in peer addrs

14:52

another thing prb apparently doesn't do, is to discard old/dead peers from its addr set.

14:52

just about erry prn node appears to offer exactly 1000 addrs

14:52

and so

14:52

some of'em have timestamps month+ in past

14:52

*prb node

14:53

*

asciilifeform only interested in polling prb nodes to the extent it helps to turn up trb-compat. elsewhere on net

14:58

upstack, shinohai , re http://logs.nosuchlabs.com/log/asciilifeform/2020-03-01#1008214 << you gotta sort | uniq , simply uniq only removes consec. duplicated lines

14:58

15:04

Yeah I forgot to add sort in the pipe in haste >.>

15:05

btw i tried to run yours on a node, ended up with awk dying a grisly death, apparently it tries to alloc a buffer for whole debug.log

15:05

needs variant w/ plain grep

15:06

i rotate debug.log erry yr , typically, so it ends up in the 10s of GB routinely

15:06

( was curious, what % of unique ip that connect, ever bring in a new block )

15:06

Really? awk spits out in < 5-6 seconds for me, strange

15:07

shinohai: cuz your log is, i expect, small

15:07

you did say the node is recent build

15:07

Yup, is rather young. (Though could easily do with grep I guess `grep -oE "\b([0-9]{1,3}\.){3}[0-9]{1,3}\b"` )

15:08

the one i was looking at just nao, is 14+GB.

15:08

Yeah mine at present is only 250 MB lol

15:09

so that'd be it.
