SSU2: Unexpected message type 212
zzz
good morning, time to investigate
zzz
06-03 00:28:52.920 WARN [ handler 1/1] .transport.udp.PeerTestManager: Bad IP length 32
zzz
should be 6 or 18
zzz
msg code flag ver nonce ts sz port ip
orignal
so, asz now
orignal
fine will check the code
zzz
remember we flipped it around at your request
zzz
used to be port sz ip I think?
orignal
yes, but it shouldn't affect length anyway
orignal
another question
orignal
what do you do if Charlie has a session with Alice already?
zzz
I didn't send anything back so I don't know what the 212 was that you got
orignal
I have fixed that part
orignal
anyway
zzz
already has session shouldn't happen, alice should know that, but there's a code for it: 68: rejected by Charlie, Alice is already connected
zzz
oh, you're right, alice doesn't know
zzz
anyway, code 68
zzz
that part I've tested because in the testnet everybody is connected to everybody
orignal
exactly
orignal
Bob picks Chralie for peer test
orignal
inlike relays
zzz
yup. need more coffee
orignal
so, Bob sends error code back. Right?
zzz
in this case, charlie sends code 68 to bob and bob forwards to alice
orignal
what if Charlie just had a session with Alice that's terminated already
orignal
but not long time ago
zzz
it's a good question, I guess the test would be a false positive
zzz
I don't remember "recently connected"
orignal
does Bob forward error code back or try another Chrlie?
zzz
I just forward the error code back. I don't retry.
zzz
I guess you could
zzz
I'll add that to the spec that it's optional, it's a good idea
orignal
see the problem
orignal
I'm Alice and got this code back
orignal
what should I do?
orignal
if I try same Bob or even another Bob it might be the same story
orignal
while Bob knows Charlie not good for Alice
zzz
what I do is the same as in SSU 1 - the test results are unknown, reschedule another test, probably with somebody else
zzz
FYI sz was 32, 32 is the first byte of your IP address 2001:... so I think your IP is in the wrong place
orignal
yes I think so too
orignal
let me check
zzz
also got a sz = 42 from some other i2pd 2a01:...
orignal
lol
orignal
somebody updated from trunk
orignal
Kirov guy again? ))
zzz
nYlJ XfR ipv6 only
orignal
then somebody else
orignal
got peer test back from you
orignal
not sure from Bob or Charlie
zzz
06-03 14:43:04.717 WARN [ handler 1/1] .transport.udp.PeerTestManager: Unable to pick a charlie (no peer), IPv6? true
zzz
should be status code 2
orignal
don't process it yet
orignal
so it looks right for now
zzz
yes
orignal
will add more processing
zzz
code 2 should be very common until we get more SSU2 routers out there
orignal
and I guess you don't verify signature at Bob
zzz

zzz
looking...
zzz
no, I only check sig of msg 2 at charlie and msg 4 at alice
orignal
yes I know
zzz
anyway, success for now, great
zzz
I think I have the Bob and Charlie sides of relay almost done... thinking about how to test
orignal
publish relay tag
zzz
yeah and I need to force-firewall it. will probably be a different router
eyedeekay
orignal, polistern do either of you have any insight into how to use i2psam(C++ SAM lib) with Boost ASIO?
eyedeekay
Trying to help this app dev with their question: zzz.i2p/topics/3324-simplest-cpp-lib-for-samv3
zzz
orignal, saw a problem on another router receiving bad ack blocks

zzz
so it's an ACK block, claims to be length 21, but there's only 16 bytes total remaining in the message (13 bytes of payload)
zzz
ack through 2f, acnt 0c, nack fe ack 00 nack 05 ack 00 nack 00 ack 00 nack 00 ack 00
zzz
so it's total garbage
zzz
please take a look
zzz
I got it several times, each one a little different
zzz
ok actually fe 00 05 00 00 00 00 00 is a padding block
zzz
to the ack block is just 0c 00 15 00 00 00 2f 0c
zzz
the length should be 5 but it's 0x15 = 21
