RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - ZerBea - 01-13-2020
Depends on the options, you used:
--use_gpsd -> if gpsd freeze, hcxdumptool will freeze, too
better choice:
---use_gps_device=your_device
make sure your device is working and has a fix:
$ cat your_device
you should receive non empty NMEA sentences
It is also possible, that the WiFi driver crashed (if you use an ath9k_htc device):
https://bugzilla.kernel.org/show_bug.cgi?id=198701
https://github.com/ZerBea/hcxdumptool/issues/80
If you're running a Raspberry Pi, make sure that WiFi device and GPS device power consumption doesn't exceed USB power limit. Maximum total USB peripheral current draw states the max USB current for Pi(2/B+) is 600/1200mA. The limit for Pi3 is 1200mA. Earlier models claim 500mA. If you don't take care about that, the RPi will freeze.
BTW:
I'm not a native english speaker, so my english isn't much better....

My sentence is "hcxdumptool -i wlx00156d72f392 -o 11enero.pcapng --enable_status=1 --filterlist_ap=blacklist.txt --use_gps_device=/dev/ttyACM0 --nmea=test.nmea"

RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - ZerBea - 01-13-2020
Ok, now we know the cause: ath9k_htc driver
I have a TPL-LINK TL-WN722N V1 for testing purpose and it shows the same "ugly" behavior.
$ hcxdumptool -I
wlan interfaces:
f81a6718410f wlp3s0f0u2 (ath9k_htc)
$ lsusb
ID 0cf3:9271 Qualcomm Atheros Communications AR9271 802.11n
First, the driver is running fine.
$ dmesg

and spams dmesg log.
At this time hcxdumptool will freeze.
And the whole system died:

RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - ZerBea - 01-13-2020
That isn't a dmesg log while hcxdumptool is running. Your log is showing NetworkManager access to the device.
As you can see from my dmesg log:
Jan 13 16:48:10.888795 tux1 kernel: kernel BUG at mm/slub.c:306!

The driver didn't accept commands from hcxdumptool any longer and crashed. The workload is too high for the driver.
RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - strike1953 - 01-13-2020
Too bad, I'll have to go back to the old hcxdumptool since Version 6 is not compatible with my hardware. I will not be able to enjoy the benefits of the hash 22000
RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - ZerBea - 01-13-2020
hashmode is independent from hcxdumptool. You can use hcxpcangtool on that pcapng files to convert them.
I'm still hunting for that kernel bug, like other coders, too:

Thank you very much your for your attention and congratulations for these tools.
RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - ZerBea - 01-13-2020
As of today, only mt76 and rt2800usb driver families are working without issues.
