orignal the question is

zzz ^^^^ stayed up 13 minutes, inbound to me

orignal why this session stayed so long

orignal why 13 minutes?

zzz vvvvvvv then after that, another successful relay, another 68, stayed up 168 seconds

zzz idle timeout changes based on number of peers

orignal I forgot for the reason

orignal because I was restarting

orignal that's why

orignal is there a way to restart session?

orignal in this case

zzz it's a good question

zzz since you lose the chacha keys we'd have to start over

orignal and it was idling for 13 minutes are you sure that HolePunch was still valid?

orignal I care more about hole punch

zzz I should ping periodically if I'm firewalled

zzz maybe, since it's signed, we could "believe" the relay request and tear down the old session. I don't know

zzz don't you send a destroy when you're restarting?

orignal well I was restaring due to hmmm ... hardware issue ))

orignal simply specking hard drive started malfuctioning there

zzz so a local destroy then ))

orignal the box has rebooted

orignal the problem with this box it's being abused all the time because mining

zzz you sure that's the reason? I got the 2nd relay intro only 12 seconds after the first. You rebooted and restarted i2p in 12 seconds?

orignal no I'm talking about first one

orignal when I received 68 after few attempts after restart

zzz yeah the first one

orignal and got confused

zzz 07-01 00:21:34.732 INFO [ handler 1/1] nsport.udp.IntroductionManager: Send relay response 0 as charlie

zzz 07-01 00:21:46.404 INFO [ handler 1/1] nsport.udp.IntroductionManager: Send relay response 68 as charlie

orignal so you think I have missed first one or what?

zzz no, because a session was actually set up between those two

orignal or you received SessionConfirmed?

zzz you can see because it expired 13 minutes later

zzz 07-01 00:34:41.718 WARN [leTimer2 4/4] r.transport.udp.PacketBuilder2: Sending termination 2 to : [2001:470:1f06:405:0:0:0:2]:29948 cdoFbN IB2 recvAge: 13m sendAge: 13m sendAttemptAge: 13m sendACKAge: 13m lifetime: 13m

zzz I wasn't logging handshake, but I must have received session confirmed, yes

orignal but again why 13 minutes?

zzz that's when it timed out for me

zzz doesn't matter if the timeout was 13 seconds. I still would have sent you a 68 after 12 seconds

orignal maybe ack to session conrirmed was missing

zzz maybe, but same thing happened twice

orignal I think I tried it again after 12 seconds

orignal it's possible

orignal but they question is what has happened with original session

zzz and I didn't see any retransmitted session confirmed from you

orignal and how we can restart

orignal I will investigate

zzz ok

orignal but restart

orignal if I send a new SessionRequest when I receive 68

orignal what will happen?

zzz in SSU 1 I'll replace the old session with the new one. Should work for SSU 2 also but haven't looked to see if it's ever happened

orignal I think how to handle 68

zzz we also need to talk about when to work on 'path challenge'

orignal agree

orignal also successive relay is still rare

orignal interesting coincidence

orignal seem relay works only through 2RRY

orignal 10:56:17@924/info - SSU2: RelayResponse status code=68

orignal wtf again?

orignal I have just started the router a minute ago

orignal I even haven't received HolePunch

orignal and my that router was offline for more than an hour

zzz wasn't my router

orignal 68 is Charlie

orignal and I tried to connect to you

zzz I'm charlie?

obscuratus In the context of SSU2, what is "Relay"? Is there somewhere I can read up on it?

zzz basically the same as in SSU 1 obscuratus see 'introduction' section in i2p-projekt.i2p/en/docs/transport/ssu

obscuratus zzz: Thanks

obscuratus Ah, hence the importance of connection time. If the introducer isn't connected, then the hole punch is lost.

orignal yes, you are

orignal the question is why 68

zzz I have not sent any 68 in the last 12 hours

orignal then any ideas where is might come from?

orignal maybe Bob did something worng?

zzz who was the bob?

orignal not 2RRY for sure
