I am running the latest release of Webmin (at time of writing) on Ubuntu Linux 20.04.1 LTS across a cluster of several machines behind a private network that talk to each other via the Webmin Servers Index module.
I love what the developers of Webmin have done to add features for managing a cluster of Webmin servers, but at least for some actions it seems like these features are only usable in a Web browser.
I successfully used the Cluster Users & Groups module today to sync user accounts from our primary Webmin system (that also has Virtualmin installed) to the three other servers in our cluster. Our list of user accounts frequently changes as new e-mail accounts are added to the virtual servers created by Virtualmin, and thus new Linux users are added to the system to support these accounts. But remembering to go into the Cluster Users & Groups module to synchronize user changes across servers on a regular basis is not ideal and does not fit well in a system administrator’s role of automating server management processes.
So, does Webmin or Virtualmin have a command-line alternative to syncing users across servers via the Cluster Users & Groups module? If not, is there a way to script the triggering of whatever Webmin does in the user interface to fire off this synchronization?
