Administrative interface

[lolocohen]

What is your idea?

It would be nice to be able to list defined entries, add new ones, modify or delete existing ones, while forward4j is running.

What are the expected benefits and drawbacks?

• ability to change the configuration without interrupting forwarded traffic
• forwarder4j could be run as a background service (e.g. Unix daemon or Windows service) and configuration changes wouldn't require a restart

Are you foreseeing any hurtles or drawbacks?

This will probably compelxify the code, with the administration part possibly bigger than the runtmle part.

Do you have suggestions on how to implement it?

• keep it as simple as possible (KISS)
• initial idea is to use raw socket communication on a configurable port, and send commands strings like:
  • ./f4j-admin.sh list to list all entries, possiblly with some kind of expression to filter the results
  • ./f4j-admin.sh +local_port=host:port to add a new entry or change an existing one
  • ./f4j-admin.sh -local_port to remove an existing entry
  • possibiltiy to send multiple commands, separated by some delimiter (|, ; or , ?)
