Re: [leshan-dev] A question regarding Leshan demo web site
|
Hi,
You can eventually run leshan-server-demo locally and so run
wireshark at server side.
Or Eventually, I can try to do a capture at server side. (as there
is not so much traffic) I'm currently running a tcpdump on the
sandbox. If you make your device communicate now I can see the
exchange.
(This will maybe be complicated to synchronize ourself, I will let
the tcpdump capturing for the next hour but I will stop it before
the end of the day)

Hi,
I
tried to connect using this sequence of commands from GSM
modem:
AT#LWM2MINJKEYS=0,1,"mark123456","mark123456","0987654321"
AT#LWM2MSTS=0,999,"coaps://leshan.eclipseprojects.io:5784",1
at#reboot
AT#LWM2MENA=1
With this sequence, I managed to connect until
Thursday after noon. In the evening I already couldn’t
connect.
I pretty much use my GSM modem as black box, so I
can’t provide much more details. I also don’t have
Wireshark.
I’ll try to find more information that you asked.
Thank you,
Mark

There must be something wrong with
either your computer's networking options, the sequence of
command you used, registration to the server (wrong key,
or a device with the same identity is registered with a
wrong key. You can check this out at
https://leshan.eclipseprojects.io/#/security) or
something else.
Hi,
Is
there some problem with this server?
It should not. But you maybe found
a bug ?
Thursday I integrated in master (and so applied on
Leshan sandbox) some commits about integration of the
new Californium version, there is maybe a regression
with this. (Californium itself or my modifications)
This could help if you provide more context. (which
client used ? DTLS or not ?, if DTLS, rpk psk or x509 ?
providing wireshark capture or log could help too)
If you prefer you can use github issue ? (Mailing list
is fine too)

Hi,
Last
week I connected with my device successfully to the
demo LESHAN server:
https://leshan.eclipseprojects.io/#/clients.
But
since Thursday I can’t connect to it, with the same
sequence of commands that I used before.
Is
there some problem with this server?
Thank
you,
Mark
