Error Keeping VRS running by cron

[Hardy]

Hello to all,
I am referring to: Re: Keep VRS running after closing telnet session
Post by argz » 27. Dec 2016, 12:38

Prior the cron "installation" VRS works just perfect, Silhouettes and Flags are loading almost instantly.
I followed the instructions to starts VRS during Boot.
But... The VRS Main page loads very, very slow the Silhouettes and Flags.
The WebAdmin Plugin keeps asking for the Username and Password.
Erasing (crontab -e) the entry @reboot /home/pi/vrs.sh,
Rebooting and starting VRS manualy by "mono /home/pi/vrs/VirtualRadar.exe -nogui" and everything works perfect as before.
(Maybe the VRS loads during Boot to quickly and RPI is not yet ready).

I am using RaspianStrechLight-4.14.50-v7 and the latest VRS & Plugins.
And I am an absolute beginner.
Any Ideas?
Best Regards – Hardy

I have to correct :
Starting VRS via crontab or rc.local makes no change.
VRS does not display Silhouettes or Flags.
VRS WebAdmin keeps asking for Password.
If I start VRS manually (Putty) then VRS works normal.

Update:

I have been playing around and noticed the following:
I have a script called vrs.sh :
#!/bin/sh
echo "Hallo, Starting mono VRS"
echo "Hallo Hardy starting mono & VRS" > /tmp/vrs.txt
mono /home/pi/vrs/VirtualRadar.exe –nogui

If I invoke the script as following from PuTTY: bash vrs.sh
everything looks & works normal.

If I invoke the script as following from PuTTY: sudo bash vrs.sh
then the Silhouettes & Flags are not displayed and the WebAdmin Plugin is not working.

I think I have screwed something up with some privileges, but I don’t know where to look and how to fix it up.

Best regards
Hardy

try:

Code: Select all

chmod +x vrs.sh

and then run it again

[Hardy]

thanks for your sugestion,
sudo chmod +x vrs.sh
makes no change.

do not use "sudo" in this case. user "pi" should be able to execute it.

i am geting:
pi@raspberrypi:~ $ chmod +x vrs.sh
chmod: changing permissions of 'vrs.sh': Operation not permitted
pi@raspberrypi:~ $

Sorry for the delay in replying. If you do

Code: Select all

ls -l vrs.sh

who owns the file? I imagine it's probably not the pi user. If you

Code: Select all

sudo chown pi vrs.sh

and then try chmod +x vrs.sh then that should give you execute permission on the file.

i am geting:
pi@raspberrypi:~ $ chmod +x vrs.sh
chmod: changing permissions of 'vrs.sh': Operation not permitted
pi@raspberrypi:~ $

enter

Code: Select all

sudo -i  

first
as pi privs are very strange on raspian
