→Useful zynthian command line commands
Use '''ssh''' to remotely access the console (terminal) of the Zynthian from another computer. Use the '''ssh''' command on Linux/Mac Terminal or use the freely downloadable '''PuTTY''' software for Windows. In most modern computer, using the name "zynthian.local" should work. If it doesn't, you can use the IP address too. See [[Finding your IP address]] for help on this.

'''''Note:''' on the new Bookworm (64bit) image, still in development, the password has changed to '''opensynth'''.''
User pi doesn't exist any more and ... it's a good idea to change the password :wink:
If you use ssh from the linux/mac terminal, it's so easy as:
ssh root@zynthian.local
or
ssh root@zynthian.lan
* User pi doesn't exist any more
* It's a good idea to change the password, specially if your zynthian is connected to public networks. You can do it easily from the webconf.
=Base Directory:=
=Base Directory:=
/zynthian
/zynthian
Most of zynthian stuff is in this directory.
=Stopping/Starting the Zynthian UI=
You must use systemd-style commands to stop & start any system service. For the zynthian UI you would use:
systemctl stop zynthian
systemctl start zynthian
If you want to run the Zynthian UI in the console, you must stop the zynthian service and run the zynthian UI as a normal script using these commands:
systemctl stop zynthian
zynthian.sh
Running zynthian from the console (terminal) allows you to view the detailed debug messages, which is convenient for solving issues. Posting these to the forum will enable experts to help you. You can also access the UI log messages from the webconf.
=Stopping/Starting the Zynthian Webconf=
systemctl stop zynthian-webconf
systemctl start zynthian-webconf
If you need access the webconf's log messages, you can use:
journalctl -u zynthian-webconf
=Configuration without WebConf=
If you can't access WebConf with a browser, you may edit this file:
/zynthian/config/zynthian_envars.sh
and run this command after saving the changes:
# zynthian_update_sys.sh
=Viewing the Zynthian graphics display on a computer=
If you are using Linux on your PC (or MacOSX with a X window server installed), you can login into your Zynthian box with '''ssh''' using the “-Y” flag:
ssh -Y root@zynthian.local
this will allow you to run graphic applications in your Zynthian, while displaying the graphics window on your PC/laptop.
=Useful zynthian command line commands=
aconnect -l list MIDI connections (that ALSA knows about)
aplay -l lists audio hardware devices (that ALSA knows about)
aplay -L lists the ALSA device names of all hardware and software devices
alsamixer graphical mixer program for the ALSA that is used to configure sound settings and adjust the volume
aseqdump show the events received at an ALSA sequencer port
jack_lsp -c lists connections to/from each JACK port
lsusb list known USB devices
lsof list of all open files and the processes that opened them.
patchage graphical modular patch bay for audio and MIDI systems based on JACK and ALSA
gpioinfo to see current GPIO status
scrot to take screenshots
export DISPLAY=:0 set which display is to be used
=Create screenshot=
1. Access to your Zynthian
2. If first time you create screenshot
=UI configuration file=
export DISPLAY=:0 set which display is to be used
3. Take the screenshot
scrot file_name.png
4. The screenshot will be in the root folder of your Zynthian
