====== Capture Running Log   ======

This guide is for users of **Ubuntu Linux**.


You can capture information from the running system log to diagnose abnormal behaviour and unexpected outputs.

===== Login via a Serial Terminal =====

Connect your PC to the SBC using a [[products:sbc:common:development:setup-serial-tool| Serial Debug Tool]].

The default account and password of Ubuntu Linux is as follows:

  * ''khadas'' - default account user name
  * ''khadas'' - default password

===== Running Log Capture =====

After logging in with the serial Terminal, you can capture the running system log via the following commands.

==== Fetch System Version Information ====

```shell
khadas@Khadas:~$ cat /etc/fenix-release > ~/system-version.log
```

==== Fetch System Kernel Information ====

```shell
khadas@Khadas:~$ sudo dmesg > ~/kernel.log
```

==== Fetch System Log Information ====

```shell
khadas@Khadas:~$ sudo tar cvzf ~/systemlog.tgz /var/log/
```

===== Send Log File =====

When reporting problems to [[kf>|Khadas Community]] or <support@khadas.com>, you can save the log file from your SBC into an SD card, and then send it off to us using your PC.
