What went wrong with my KiwiSDR ? [corrupt kiwi.json file]

edited December 2022 in Problems Now Fixed

Hi all,

After v1.570 automatically updated, I encountered a problem as follow,

I can see this KiwiSDR and IP address in my router connected clients ...


But I cannot connect it with that local IP/port with Firefox

and I cannot connect it with my.kiwisdr.com for a local device surveying either,

I have no idea what happened to it ...

Should I recover Kiwi with SD card ? or try other method ...

Thank for your suggestion in advance.

  • Try clearing your browser cache or try another browser.

    It may just take a while to update fully, so I would leave it for a while before considering a recovery.

    Can you ping it or SSH into it ?

  • Hi Martin,

    Glad to see you again ~ this is the status :

    Try clearing your browser cache or try another browser. => Done, both Chrome/Opera (brand-new installed at PC) failed the connection too.

    Before issue happened, the firmware has been updated to 1.570 and worked fine one or two days.

    Ping it. => Got responses as can be seen below.

    SSH into it. => Serial-port connection to BBG ? I'm noob with EVB/Linux and never dd things like that before. . well i have to learn this a while and prepare for the worst.

    thanks a lot, anyway.

  • Hi Jimmy,

    That's odd.

    What happens if you ask for it's status using the webrowser as normal with /status after the port number, assuming you are using 8073

    192.168.1.151:8073/status

    Unfortunately that's about my limit with Linux too, but it looks like either the webserver part has stopped or the port number has changed.

    Have you tried a power cycle ?

    Otherwise it's over to more qualified folks to comment.

    Regards,

    Martin

  • Isn't there an ssh available from the command line in Windows? Failing that, try the PuTTY application. So first try ssh root@192.168.1.151 and use the Kiwi serial number as the password (written on the top of the Kiwi circuit board in the white box).

    Once connected try these commands:

    cdp

    ps ax | gr kiwid

    msl

    Email the resulting messages to support@kiwisdr.com


  • Hi, jks

    Putty access for log was done.

    Mail sent and thank for your help in advance.

    B/R,

  • Hi Jimmy,

    Thanks for your complete and detailed email. It really helps me when people send me the info I ask for. You were correct. There was indeed an error parsing the configuration file kiwi.json We've seen this happen a few times in the past. It is not clear why this happens. Possibly a power failure at a bad time (when the file was being written).

    You should be able to get the Kiwi going again by using these commands after an ssh connection:

    cdp

    cp unix_env/kiwi.config/dist.kiwi.json ../kiwi.config/kiwi.json

    Note the ".." (two dots) above. When the Kiwi server next restarts (in a minute or so) it should begin running normally. Your customizations will be lost, but it is much better than having to start over re-flashing using the sd card.

    If you happen to have a backup made using the admin page, backup tab function, then a more recent kiwi.json file with some of your customizations can be recovered. Let me know we need to do this.

  • Hi jks,

    These command lines are really powerful and work well ! Thanks a lot.


    As a record shown below is the ssh msg I see in this issue, and hope it can help someone too in the future.


    Enjoy KiwiSDR !


    regards,

    Jimmy

  • Eventually my kiwi revives with full hp tonight.

    Thank for jks & G8JNJ gurus' help.

    continue my noise reduction engineering ...
