open swt ui while running biglybt console and telnet ui in systemd

[moham96]

Hi,
I want to run biglybt inside a systemd service while still being able to run swt ui. I used the following service file

[Unit]
Description=BiglyBt daemon
After=network-online.target

[Service]
Environment=DISPLAY=0.0
Type=simple
User=pi
ExecStart=/usr/bin/java -cp /home/pi/biglybt_stock/BiglyBT.jar -Djava.library.path=/home/pi/biglybt_stock -Dbiglybt.install.path=/home/pi/biglybt_stock -Dazureus.script=/home/pi/biglybt_stock/biglybt -Dazureus.config.path=/home/pi/.biglybt_stock -Dazureus.overridelog=1 -Dazureus.overridelogdir=/home/pi/biglybtlogs/ -Ddebug.swtexec=1 com.biglybt.ui.Main --ui="console,telnet"
ExecStop=/usr/bin/java -cp /home/pi/biglybt_stock/BiglyBT.jar -Djava.library.path=/home/pi/biglybt_stock -Dbiglybt.install.path=/home/pi/biglybt_stock -Dazureus.script=/home/pi/biglybt_stock/biglybt -Dazureus.config.path=/home/pi/.biglybt_stock  com.biglybt.ui.Main --shutdown
SuccessExitStatus=143

[Install]
WantedBy=multi-user.target

and I can start and stop the service and connect through telnet, but when i execute ui swt inside a telnet session i get

Unable to init server: Could not connect: Connection refused

inside the systemd logs and the service exits

[parg]

Perhaps you need to include the swt jar file in the classpath?

[moham96]

@parg I Did include it but the problem persists, the problem only happens when I run the command inside systemd service, if I run the same command /usr/bin/java -cp /home/pi/biglybt_stock/BiglyBT.jar -Djava.library.path=/home/pi/biglybt_stock -Dbiglybt.install.path=/home/pi/biglybt_stock -Dazureus.script=/home/pi/biglybt_stock/biglybt -Dazureus.config.path=/home/pi/.biglybt_stock -Dazureus.overridelog=1 -Dazureus.overridelogdir=/home/pi/biglybtlogs/ -Ddebug.swtexec=1 com.biglybt.ui.Main --ui="console,telnet" from a terminal and then started swt using telnet then everything works

[parg]

Hmm, I don't know anything about the context within which systemd might be running BBT :( The error message you see is somewhat peculiar, no idea what 'server' it is trying to init or connect to.

[moham96]

@parg I think this means the x server.Maybe @TuxPaper can be of a help here

[TuxPaper]

Is this a wayland desktop? They (and maybe other desktop UIs) prevent running desktop ui apps from root and most other accounts.

https://fedoraproject.org/wiki/Common_F25_bugs#wayland-root-apps

We use the xhost +si:localuser:root (temporarily) in our installer on Wayland in order for the gui to appear, and it mostly works, so maybe something similar will help for you.

[moham96]

@TuxPaper It's not running wayland, I tried it on raspbian stretch(lxde) and manjaro running x.org, also I'm not running the process as root anyway beacuse i used User=pi in the service file

[moham96]

Well this embarrassing, there is a stupid error in the service file' I passed DISPLAY=0.0 as an environment variable which should be DISPLAY=:0.0 the works now

[parg]

yay

[moham96]

@parg Now I have another error popping in the logs

should i open a new issue for this error ?

[parg]

seems to be attempting to write at / - perhaps you need an additional

-Duser.dir=/home/pi/biglybt_stock

[moham96]

@parg ok that solved the issue but I get yet another error, it's probably not very important but I just want to make sure of it:

Stopping console input reader because of exception: stream closed
