zzz
not out of ideas yet
zzz
there's a lot going on if you know where to look
orignal
I see few exploratory lookups per second as 2RRY
orignal
*at
orignal
is it expected?
zzz
I don't know what a typical expl. lookup rate is
orignal
the question is if you are capable to handle them
orignal
2RRY returns 16 hashes now
dr|z3d
are you asking about lookups, orignal?
orignal
yes
orignal
if too many exploratory lookup and they are heavy
dr|z3d
I think zzz mentioned before that canon's lookup throttle is pretty low.
dr|z3d
I don't remember the numbers exactly, something like 9 is 2m?
dr|z3d
*9/2m
orignal
I receive few exploratory lookups per second at 2RRY
dr|z3d
with my new limits, I'm not seeing much in the way of bans right now.
dr|z3d
max 30/30s before ban, or 60/90s before ignore.
orignal
I'm asking about not from the same source
orignal
but overall
dr|z3d
oh
orignal
and for exploratory only
orignal
it seems it's a potential attack vector
orignal
if an adersary start sending tonns of exploratory lookups to floodfill from different sources
zzz
sure I can handle 16
dr|z3d
so you're suggesting some sort of global rate limit for expl lookups, orignal?
zzz
wo was having persistent trouble with the form nonces? I know why
orignal
no I mean how many lookups you can handle
dr|z3d
zzz: go on, enlighten us..
dr|z3d
that was the channel mascot blob, mesh.
zzz
tabs for consoles for multiple routers up in same browser, same IP (or ssh forwarding), solution is different IPs like 127.0.0.2, ::1, localhost, etc
zzz
browsers don't respect different ports when sending cookies
dr|z3d
yeah, I mentioned that to him before, but it depends on which browser.
dr|z3d
if you're on firefox, things might be ok. chrome and friends, dunno.
zzz
simultaneous http and https to one router also will do it
dr|z3d
firefox now does tab-isolation, so you should be able to run multiple routers on the same address.
zzz
no, firefox not ok
dr|z3d
ah, then you probably don't have tab isolation active.
dr|z3d
I've given up trying to track when mozilla decide to default enable various features.
dr|z3d
librewolf does appear to default to that behavior.
dr|z3d
I've got at least 3 consoles via ssh running on different ports on localhost, no issue with nonces.
dr|z3d
localhost as in //localhost:port
dr|z3d
I definitely used to have issues, which is why I was emphatic when telling mesh to not run more than one console in a browser session, with only 1 tab for the console.
dr|z3d
and definitely don't run the same console in multiple browsers, that's asking for trouble.
zzz
different IPs for different routers always works
dr|z3d
indeed it does.
dr|z3d
if you want to get clever, add multiple hostnames to your hosts file all pointing at 127.0.0.1 with names for each router.
orignal
guys what timeout should I set between two requests of the same destination?
orignal
like 3 minutes?
orignal
e.g. if I requessted a dest and it was not found I wait for 3 minutes
zzz
i.e. the negative lookup cache time?
orignal
yes
orignal
doesn't matter negative or poisitive basically
orignal
lookup might return a malformed router
zzz
well, it's important not to have two lookups for the same thing in progress at the same time, "combine" them together
orignal
e.g. lookup itself was positive but the router is not in netdb
orignal
that's I'm doing now
zzz
our negative cache time is two minutes
zzz
but it's bucketed, so average is one minute
orignal
if I see a lookup going on I only add callback to it if presented
orignal
2 minutes. thanks.
orignal
then 1 minutes after lookup complete
zzz
I think we require 2 or 3 consecutive fails before we put it in the negative cache though
zzz
play around with it
orignal
why?
orignal
I try 7 attaempts
zzz
dunno, maybe a transient issue
orignal
until it failes
zzz
can't remember
orignal
if it fails no reson to try again
zzz
we do 5. 7 sounds like a lot, but you can look at your data and see if 7 is worth it
zzz
hard to get to 7 with a reasonable timeout
orignal
I don't remeber where 7 attamepts came from
orignal
it was long time ago
orignal
and I suspect it was your suggestion
orignal
my timeout is 5 second per request
orignal
and 30 second for exploratory
zzz
netDb.successRetries: How many additional queries for an iterative search
zzz
Lifetime average value: 1.299 (53,616 events)
zzz
so we're querying 2.3 peers on average (for a successful lookup)
orignal
Vort measured it
orignal
usually stops at 3
orignal
so you suggest to descrease number of attempts to 5?
zzz
I suggest you research it, look at your data. Maybe 7 is too many, maybe not
orignal
question
orignal
what we do if we receive an exploratory request with real ident?
orignal
leaseset lookups are also up to 7
