Kannel auto startup problem with System error 13 Permission Denied

[with reference to following

DMASOFTLAB Radius Manager 4.0.4/4.1.x SMS Notification Configuration

https://aacable.wordpress.com/2012/11/26/howto-configure-your-local-http-gateway-using-kannel-on-ubuntu/ ]

Recently I configured KANNEL (again) for a client in KARBALA/IRAQ. The OS was UBUNTU 12.04.When we run the Bearerbox and SMSBOX manually in terminal, KANNEL HTTP API works fine. But when the box is restarted, SMS goes in QUEUE.

Result for manually executed bearerbox and smsbox in terminal (separate terminal for each command) like

bearerbox -v 0 /etc/kannel/kannel.conf

smsbox -v 0 /etc/kannel/kannel.conf

Sms via web works fine.

But when the system is rebooted ,  and I tried to send SMS , all messages were going in QUEUE and following message appear on browser.

3: Queued for later delivery

All kannel related services were starting properly, like bearerbox, smsbox etc. As showed below …

root@rm:~# ps aux |grep kannel

After checking the bearerbox.log, I saw following error

tail -f /var/log/kannel/bearerbox.log

With the help of kannel users mailing list, I found that KANNEL user must be allowed to write access /dev/ttyACM0 (or your modem device name).

For ubuntu, simply add the user KANNEL to DIALOUT group.

usermod -a -G dialout kannel
chown  kannel  /dev/ttyACM0

---

Also remove the comment sign from START_SMSBOX in /etc/default/kannel so that smsbox may also start on system boot.

Alhamdolillah Problem Solved!

I am sharing this info because it took around 1 days of head banging with the wall, and I surely dont want anyone else to stuck in the same situation (if the issue is same)

Sample of config files
