wireshark + (lowlevel driver or linux) , or use tcpdump at the router.
wireshark can decode wlan when you know the key.
Mario Mikočević
@mozgy
I have RasPi on wlan for that :)
Markus
@Links2004
openwrt on the router make it easy too, call tcpdump and you are done.
brutzler
@brutzler
haha ... openwrt. Only a Fritz with AVM-OS
Markus
@Links2004
yes hidden webinterface :)
brutzler
@brutzler
more input pls

@brutzler
Raspi is somewhere around. Any Howto for this?
Markus
@Links2004
no need use the url and you can capture as wireshark file
brutzler
@brutzler
Fritz tells me: URL not found. Redirected to main page.....

Hi, the sntp makes an request on start, and about one hour later, nearly one hour. Then you see a new timestamp with Serial.setDebugOutput(true).
Markus
@Links2004
try fritz.box/html/capture.html
shut look like:

@brutzler
ahh better... never seen this. will need some time to get it working
Markus
@Links2004
press start an it will work ;)
brutzler
@brutzler
haha ..... a lot of "START".
Markus
@Links2004
wifi ?
brutzler
@brutzler
still five ;-) AP or HW
Markus
@Links2004
AP Schnittstelle 0

@brutzler
OK, working.

How can I post an image?
Markus
@Links2004
C&P it in
will work for any file.
Dmitry Kireev
@kireevco
@brutzler or upload it somewhere and post a link via markdown ![]()
C&P doesn’ work for me - mac client

a little bit different to yours
Markus
@Links2004
other fritzbox :)
brutzler
@brutzler
I am sure. You have one with only 2,4GHz ?
Markus
@Links2004
can make images of 5 different when i want, reinforced concrete ins´t good for wifi.
it was a 7270 5Ghz disabled
brutzler
@brutzler
OK. using FritzBox nearly over 10 years, But never seen the capture possibility ....shocked....
Markus
@Links2004
its not linked in the normal web interface, its a hidden debug feature.
you can capture all internet traffic with it, very useful for debugging IoT thinks and reverse engineering
brutzler
@brutzler
What is the difference between "AP Schnittstelle 0" and "AP Schnittstelle 1"
Markus
@Links2004
AP 1 is the "gast" wifi when aktive.
brutzler
@brutzler
ok, needful background. Looks like I will have to search for a doc/howto regarding this feature, to complete my documentation
@Links2004 you earned a bear for your help. What part of D r u from?

@mozgy: how do you sniff with a RasPi?
Want to have a look at the other side too
brutzler
@brutzler
Just found one of my RasPis with Wlan-Dongle. Should be enough hardware
Mario Mikočević
@mozgy
WiFi USB dongle
brutzler
@brutzler
Yes, have one (as i told). Any special software? Tshark, or....?
Mario Mikočević
@mozgy
plain tcpdump
brutzler
@brutzler
do I get an online dump with this? or do i have to dump into a file?
Hmmm....I like the gui and the filter possibility of wireshark. And it is "online" No need of dumping into a file.
Is there any äquivalent on Raspi for this?
And is it possible to sniff packages from different WiFi-modules? On normal LAN I use a switch with port mirroring to sniff "foreign" packages
brutzler
@brutzler
Other idea: Use the WiFi Dongle on my W7-computer. looking for a driver to let wireshark work with the WiFi-interface. But is it possible to sniff all packages in the WLAN-network? Or only own telegrams. If I can not sniff the packages from my ESP, then the solution from Links2004 "capturing on the router" is the best (and only) way.
