====== Multi Packet Forwarder  ======


===== Multi lorafwd instance management =====

=== Compatibility ===
This feature is available from KerOS version 5.1.

=== Features ===
Following features are available:

  *  Add a new instance of lorafwd
  *  Delete an instance of lorafwd
  *  Check if an instance exists
  *  List all added instances

=== How does it work? ===
KerOS firmware contains lorafwd template files located in /etc/lorafwd/templates/. These files must not be deleted or modified.

Each time a lorafwd is added, these templates files are copied, modified and suffixed with new lorafwd instance name.

For example, if lorafwd instance "foo" is added and runs, it leads to the following created files:

  * /etc/default/lorafwd_foo # Created with lorafwd_instance_manager script
  * /etc/init.d/lorafwd_foo # Created with lorafwd_instance_manager script
  * /etc/monit.d/lorafwd_foo # Created with lorafwd_instance_manager script
  * /etc/rcK.d/K52lorafwd_foo # Created with lorafwd_instance_manager script
  * /etc/rcU.d/S51lorafwd_foo # Created with lorafwd_instance_manager script
  * /etc/rsyslog.d/lorafwd_foo # Created with lorafwd_instance_manager script
  * /etc/sysupgrade.d/lorafwd_foo.conf # Created at first start
  * /etc/lorafwd_foo.toml # Created with lorafwd_instance_manager script
  * /run/lora/lorafwd_foo.pid # Created each time it is started
  * /tmp/lorafwd_foo_version # Created each time it is started
  * /usr/sbin/lorafwd_foo -> /usr/sbin/lorafwd # Created with lorafwd_instance_manager script
  * /var/lib/lorafwd_foo/database.sqlite # Created at first start
  * Configuration files, sqlite database and pid files are duplicated. That means all lorafwd instances are separated.

=== lorafwd_instance_manager commands ===

**add command**
Add lorafwd instance. The arguments are the following:

  * instance_name: unique lorafwd instance name ("foo" in previous example)

Example:
''lorafwd_instance_manager add foo''


**delete command**
Delete additional lorafwd instance. The arguments are the following:

  * instance_name: unique lorafwd instance name ("foo" in previous example)
 
Example:
''lorafwd_instance_manager delete foo''

**check command**
Check if additional lorafwd instance exists. The arguments are the following:

  * instance_name: unique lorafwd instance name ("foo" in previous example)

Example:
''lorafwd_instance_manager check foo''

**list command**
List additional lorafwd instances.

Example:
''lorafwd_instance_manager list''

===== Logs Example: ===== 


Logs
All lorafwd instances write to the same log file (like lorad) /var/log/lora.log, but each lorafwd is suffixed, for example:
