Step 1: Include openSER in the linux boot.

cd /usr/src/openser-1.2.2-tls/packaging/debian
cp openser.default /etc/default/openser
cp openser.init /etc/init.d/openser
update-rc.d openser defaults 99

Step 2: Edit the /etc/openser/openser.cfg file and remove the line fork=no (even if it has C-style remarks). The init script looks for the instruction fork=no, even if commented.

Step 3: Make sure that the script openser.init has the necessary permissions

cd /etc/init.d
chmod 755 openser

Step 4: Edit /etc/default/openser.cfg, change the memory parameter to 128MB and the RUN_OPENSER to yes.

Step 5: Edit the init script to make sure that the daemon is pointing to the right directory:

vi /etc/init.d/openser

File before making changes:

DAEMON=/usr/sbin/openser

File after making changes:

DAEMON=/sbin/openser

Step 6: Restart the computer to see if OpenSER starts. Confirm using:

ps-ef |grep openser.
