Start shrew vpn client (iked & ikec) on start-up of OSMC on Raspberry 2 - raspberry-pi

Question

I would like to connect to a VPN on start-up of OSMC.
Environment:
installed OSMC on Raspberry 2
downloaded, compiled and installed shrew soft vpn on the device
As user 'osmc' with ssh
> sudo iked starts the daemon successfully
> ikec -r "test.vpn" -a starts the client, loads the config and connects successfully
rc.local:
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
sudo iked >> /home/osmc/iked.log 2>> /home/osmc/iked.error.log &
ikec -a -r "test.vpn" >> /home/osmc/ikec.log 2>> /home/osmc/ikec.error.log &
exit 0
after start of raspberry iked is as process visible with ps -e
but ikec is not running
osmc#osmc:~$ /etc/rc.local starts the script and connects to vpn successfully
Problem:
Why does the script not working correctly on start-up?
Thank you for your help!

I was also looking to do the same thing as you and ran into the same problem. I'm no linux expert, but I did figure out a workaround.
I created a script called ikec_after_reboot.sh and it looks like this...
$ cat ikec_after_reboot.sh
#!/bin/bash
echo "Starting ikec"
ikec -r test.vpn -a
I then installed cron.
sudo apt-get update
sudo apt-get install cron
Edit the cron job as root and run the ikec script 60 seconds after reboot.
sudo crontab -e
SHELL=/bin/bash
#reboot sleep 60 && /home/osmc/ikec_after_reboot.sh & >> /home/osmc/ikec.log 2>&1
Now edit your /etc/rc.local file and add the following.
sudo iked >> //home/osmc/iked.log 2>> /home/osmc/iked.error.log &
exit 0
Hopefully, this is helpful to you.
