Webmin Cluster Copy Protocol

Question

Just toying with a clustered server farm for fun (as you do) and experimenting with Webmin and its 'clustered' modules.

It has a feature that can copy files from one server to another on a repeating basis. Does this feature/module use cron jobs and what protocol does it use to copy the files?

I have searched all about the net and yet I cannot find any decent documentation on webmin or its features. Is it just poorly documented or am I missing something?

Answer 1

My guess is that it uses rsync with cron, which is the canonical way of handling this type of replication. I would be very surprised if they used anything else.

Answer 2

I have recently discovered that it uses it's OWN protocol using a specific port. A few above 10000 if I remember correctly.
