The Replicator Service can be installed on Linux. In this case, the configuration and management applications (SQDR Configuration, Data Replicator Manager, and SQDR Service Properties) are run from a remote Windows workstation. You can use the SQDRPowerShell cmdlet from either Windows or Linux.
SQDR Plus (Tier 2 - the Capture Agent for incremental replications) can also be installed on Linux.
