Running executable with systemd

hello all I have an executable i can click to start my vnc looks like

#!/usr/bin/sh -
x0vncserver -display :0 -passwordfile ~/.vnc/passwd

It is named blamnet.sh Then I have a systemd file looks like

[Unit]
Description=blamnet

[Service]
Type=simple
ExecStart=/usr/bin/blamnet.sh
KillMode=process

[Install]
WantedBy=graphical.target

it is named blamnet.service I really just want to run it after my network connects but when i do
systemctl enable blamnet
then
systemctl start blamnet
it appers to start but no vnc server
can anyone point me in the right direction?

Re: Running executable with systemd

The answer would come from a combination of establishing why your service fails (`systemctl status -l yourservice.service`) and `man systemd.service`...

Re: Running executable with systemd

here is the result of

systemctl status -l blamnet.service

 blamnet.service - blamnet
   Loaded: loaded (/etc/systemd/system/blamnet.service; enabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Mon 2015-02-02 05:49:26 UTC; 39min ago
  Process: 557 ExecStart=/usr/bin/blamnet.sh (code=exited, status=1/FAILURE)
 Main PID: 557 (code=exited, status=1/FAILURE)

what should I be looking for? I don't see any kind of error code or description of failure unless 1/failure is it

Re: Running executable with systemd

Are you not going to make any effort to solve this yourself?

Read the wiki page, there is an example service file there...

Re: Running executable with systemd

I have tried ever form of .target and i have tried many examples. i have changed to all types and i started with the example off the wiki page. Perhaps I need to be more specific...  but i don't know why it wont work.

Re: Running executable with systemd

Spend more time on the wiki...the systemd entry gives clear guidance for what you ought to do to investigate further.

Re: Running executable with systemd

here is example of vnc wiki

[Unit]
Description=Remote desktop service (VNC)
After=syslog.target network.target

[Service]
Type=simple
User=
PAMName=login

# Clean any existing files in /tmp/.X11-unix environment
ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
ExecStart=/usr/bin/vncserver -geometry 1440x900 -fg -alwaysshared -dpi 100 %i
ExecStop=/usr/bin/vncserver -kill %i

[Install]
WantedBy=multi-user.target

I tried it with my user pluged in and it will not work, but it's not what i want to do anyway i just want to run the executable i made after start up I think my problem is that it needs to be forking since my executable starts a vnc server, but i guess maybe i dont know how to fork it.

Re: Running executable with systemd

Re: Running executable with systemd

Thanks guys I tried ending process restarting and getting new PID journal still blank. Perhaps i need sudo too read or something but I'm spent today. I do thank you and I understand your frustrated because I do not fully understand the wiki. I was hoping you could see my error from my code, but I will return to studying systemd as advised.
