Keep VRS running after closing telnet session

[peteclyde]

Hey all,

I've got VRS running on my Pi3 - to get it started I telnet / ssh into the Pi, and run

Code: Select all

mono VirtualRadar.exe -nogui

I've got no troubles access the web interface, as well as the admin section.

However, when I either hit the Q button in the ssh session, or close Putty, the program stops. I've tried ctrl-x and trying to make it a foreground job to no avail.

I'm sure there's an easy way to do it but a search of the forums hasn't helped me as yet.

I even tried setting it to load on boot but even then I'm not having any luck.

Any help appreciated.

Pete

OK, got it sorted, not sure if it's the best way but it works.

Installed tmux on my Raspberry pi

Code: Select all

pi@raspberrypi:~ $ sudo apt-get install tmux

Started tmux

Code: Select all

pi@raspberrypi:~ $ tmux

Inside the tmux terminal I started VRS

Code: Select all

mono /home/pi/vrs/VirtualRadar.exe -nogui

Then to exit tmux, but leave VRS running, I did Ctrl+b then d

Seems to work fine and resolved my issue.

You can just do

Code: Select all

mono /home/pi/vrs/VirtualRadar.exe -nogui &

Pleace notice & symbol in the end of the command.

This will force mono to run in the background.

I even tried setting it to load on boot

You should use Cron.
1. Create in the home directory file vrs.sh with the following text:

Code: Select all

#!/bin/sh
mono /home/pi/vrs/VirtualRadar.exe -nogui

2. Make sure the script is executable

Code: Select all

chmod +x  /home/pi/vrs.sh

3. Open crontab editor

Code: Select all

crontab -e

4. Add this code

Code: Select all

@reboot  /home/pi/vrs.sh

5. Close editor (do not forget to save)
6. Check jobs

Code: Select all

crontab -l

7. Reboot your RPi
8. Enjoy!

Hey Argz,

The first option

Code: Select all

mono /home/pi/vrs/VirtualRadar.exe -nogui &

didn't work, but the second one works fine.

Code: Select all

#!/bin/sh
mono /home/pi/vrs/VirtualRadar.exe -nogui
chmod +x  /home/pi/vrs.sh
crontab -e
@reboot  /home/pi/vrs.sh

Thanks heaps,

Pete

didn't work,

Could you post here a terminal output after this command?

[peteclyde]

Hi

It just started the program as if the & wasn't there.... like the & had no effect.

PM

[argz]

like the & had no effect

After you run

Code: Select all

mono /home/pi/vrs/VirtualRadar.exe -nogui &

press enter. After that you should be able to run new commands.

[peteclyde]

Program stops when I start it with &

Code: Select all

pi@raspberrypi:~ $ mono /home/pi/vrs/VirtualRadar.exe -nogui &

Try this maybe:

Code: Select all

mono /home/pi/vrs/VirtualRadar.exe -nogui &>/dev/null

hey,
probs to late now but i had the same issue, i fixed it by installing screen to the linux system.

i then open the server throw putty and type screen then enter.

then i run the the vrs then once open i press ctrl a and d and theis puts vrs into screen mode which then allows you to access other stuff on the server or allows you to close out of the server complete allowing vrs to still run
