like programming a replication task automatically

I have not been able to make the programming of an automatic task, it forms thus in the option Scheduler * 8-16 * * 1-5, or as I must make to every day leave it the process of the month automatic

IBReplServerService / IBReplC

I do not understand exactly. You setup "cron" pattern and rum IBReplServerService that will periodically check if current date matches "cron" pattern for all preconfigured tasks. If true then replication is performed.

You can also run IBReplC e.g. from system scheduler. It this case particular task is performed and IBReplC terminates. Note that IBReplServerService is not ported to linux.

It works also in IBReplServer but it is running in GUI.
