LoRa Gateway Developer kit RAK831 - Can't login



  • Recently received the above kit. Successfully have it connected to WiFi network. Gets IP from DHCP server. SSH is enabled, port 22 is open (confirmed with nmap).

    When SSH to device using pi/raspberry I get permission denied. Any ideas why user account changed from default or what it could be?



  • The official is not modified.



  • @xc.c I can't login using the default - any suggestions as opposed to starting from scratch? I had expected to receive the component parts and I was to assemble however the kit came completely assembled and software all installed, including packet forwarder etc.



  • So I inserted SD card into another machine, opened the file 'cmdline.txt' and added 'rw init=/bin/sh' to the end. Then entered su and passwd pi to change the pi password.

    I then inspected the contents of /var/log/auth.log

    pi@ttn-gateway:/var/log $ cat auth.log

    The notable line is: "Mar 13 08:30:00 ttn-gateway passwd[1174]: pam_unix(passwd:chauthtok): password changed for pi"
    I first powered the unit on Mar 25.

  • @xc.c See auth.log post



  • Same problem here. I just received the rak831 packaged with the converter board and the rp3 and cannot login with ssh. Tried the default pi/raspberry but get an 'access denied' error. I can change the password but think I'll just wipe the card...not really trusting what it is running. Anyone know the password RAK is shipping with or has this image been tampered with?



  • Same problem here, apparently the pi password is not raspberry.



  • You can use Raspberry Pi's official system and follow the tutorial here to create a RAK831 connection to the TTN system.

  • Same problem here, cannot ssh using pi/raspberry
