SSU2: PeerTest msg=4 code=70
orignal
I have receive error code 70 that's basically Alice unknown
orignal
but Alice was me and I do have SSU2 address
orignal
any issue with RI block?
zzz
<zzz> I was working on that over the weekend.
zzz
<zzz> basically I couldn't handle RI arriving after peer test
zzz
<zzz> fixed yesterday, I doubt anybody has updated yet
zzz
<zzz> it would also help if you put the ri block before the peer test block, or sent it first
zzz
otherwise I have to set a timer and wait for it
zzz
no big deal for peer test where latency doesn't matter, but important for relay
orignal
I didn't receive it
orignal
probably was disconnected
orignal
what? I always put RI block before peer test
zzz
ok, great
zzz
I didn't know
orignal
that's why I'm confused about 70
orignal
previously you said you couldn't find intro key in Alice's RI
zzz
that's a different error code I think
zzz
maybe RI block was in different packet and got lost
orignal
I don't know how Java sends it
orignal
it Bob was i2pd it would be in the same packet
orignal
my RI was short
zzz
doesn't always fit of course
zzz
always separate packet right now for java
orignal
that might be the reason
orignal
and as I said sometimes I receive peer test message
orignal
basically msg 5
orignal
but wrong conn id
zzz
and things get reordered in my queues
orignal
let's double check how we make it
zzz
also I had the conn ids wrong on hole punch, fixed a few days ago
orignal
<orignal> zzz, if nonce is 1 should it look like 01 00 00 00 01 00 00 00 in a packet?
zzz
I think I have it right on msg 5?
orignal
please conform it
orignal
I'm not sure who has it wrong
zzz
no, big endian
zzz
not sure if it says that in the spec
orignal
so, 00 00 00 01 00 00 00 01
zzz
correct
orignal
it says but it's not clear what we make BE
orignal
nonce or connid
zzz
either way works ))
orignal
not sure
orignal
probably
orignal
anyway let me print out and see
zzz
ok I think I just finished my MTU fixes
zzz
first fragment can be 5 bytes bigger than followon fragments, I wasn't doing that
orignal
I haven't start it yet
zzz
and I wasn't counting the 5 bytes overhead in followon fragments so I was exceeding the MTU
zzz
I had one error, ever, of trying to send a 1501 byte packet, but that was enough to chase it down
orignal
my mistake it was RelayRequest
orignal
can it be sent without session?
zzz
no
orignal
never mind it was Peer Test
orignal
mixed with block type
zzz
0) Hi
zzz
hi
orignal
hi
zzz
idk and zab are on the road
orignal
as usual
zzz
I got the slides from the student presentation
zzz
I think they looked at i2pd
zzz
links on my forum
orignal
who?
orignal
will check
zzz
these students from switzerland, sponsored by diva.exchange, presented at monerocon on saturday
zzz
I gave them some advice a month or two ago, but I thought they were looking at java i2p. guess they changed their minds
zzz
anyway, what's on the agenda?
orignal
SSU2
zzz
ok that's 1)
orignal
I don't have anything else for now
zzz
I don't really have much else
zzz
1) SSU2
zzz
I'll go first... just fixing bugs
zzz
nothing big to report
zzz
I'm getting maybe 5-10 simultaneous connections now
orignal
the same
orignal
keep investigating that nonce issue
orignal
sec
orignal
brb in a minute
zzz
so it's getting easier to test
zzz
I'm announcing a new dev version about once a week on my forum
zzz
will probably do that tomorrow
zzz
still making minor updates and fixes to the spec
zzz
that's about it, EOT
zzz
what's your status?
orignal
many things work
orignal
peer test
orignal
as I said investigating nonce for msg 5
orignal
also working on replacemnt SSU by SSU2 if configured
orignal
e.g. SSU2 only no SSU1
zzz
I logged ack blocks and ranges for a while. what I'm getting from i2pd looks good
zzz
here's an example of one that seems to be on a bad connection:
zzz
Got new ACK block from bAU~6X ACK 43-18 NACK 17 ACK 16-13 NACK 12 ACK 11 NACK 10-9
zzz
ACK 8-4 NACK 3 ACK 2-0
orignal
very good
orignal
seems I have fixed it finally
zzz
also I verified you fixed the expiration on the new token block
orignal
what threshold do you use for expiration time?
orignal
e.g. if you have token that's about to expire
zzz
I don't have any
zzz
maybe I should
zzz
any other status or issues?
orignal
I use 2 seconds for now
zzz
ok
orignal
no other issues
orignal
moving forward well
zzz
yes
zzz
anything else on 1) ?
zzz
anything else for the meeting ?
orignal
no
orignal
when idk is back?
zzz
not sure, he might be flying back today
orignal
so next meeting
zzz
for sure
orignal
please confirm that (nonce << 32) | nonce is incoming connid for Alice
orignal
e.g. Charlie puts it to Destination Conn ID in PeerTest messages
orignal
because I receive them inverted
orignal
SSU2: PeerTest nonce=429696389 connid=9630275011632012313
orignal
SSU2: Unexpected PeerTest message SourceConnID=8816469062077539302 DestConnID= 9630275011632012313
orignal
but this is for Alice side
zzz
looking...
orignal
connid is session->m_SourceConnID = htobe64 (((uint64_t)nonce << 32) | nonce);
orignal
so I palce this value into sourceconnid for Alice
orignal
but you use it as SourceConnID for Charlie
zzz
Connection IDs: The two connection IDs are derived from the test nonce. For messages sent from Charlie to Alice, the Destination Connection ID is two copies of the 4-byte big-endian test nonce, i.e. ((nonce << 32) | nonce). The Source Connection ID is the inverse of the Destination Connection ID, i.e. ~((nonce << 32) | nonce). For messages sent from Alice to Charlie, swap the two connection IDs.
orignal
yes, from the specs
orignal
but you reverse it
zzz
do I
zzz
?
zzz
for 5 and 7, dest conn ID is nonce<<32 | nonce
orignal
but see what I receive
zzz
ok, now time to look at my code :)
orignal
you put this nonce<<32 | nonce into SourceConnID
orignal
Alice places in into SourceConnID
orignal
and expect message from Charlie in DestConnID e.g. in first 8 bytes
orignal
it's clear that endianess is right
zzz
long rcvId = (nonce << 32) | nonce;
zzz
long sendId = ~rcvId;
zzz
you're right, I'm wrong
orignal
will you fix it?
zzz
of course
zzz
good catch
orignal
thanks
zzz
will double-check the others too
orignal
spend last 2 days ))
zzz
6 and 7 and hole punch
zzz
sorry :(
orignal
thought it's endianess
orignal
no problem
orignal
at least we do receive msg 5
orignal
and it looks right
zzz
6 and 7 were wrong also
orignal
I haven't reached this state anyway
zzz
hole punch was right
orignal
good
orignal
I will check also
