Moebius does not send any data to the Moebius server; it only receives data via HTTPS. The client gets the address and the port of the Moebius server from the configuration file. The Moebius server can send a configuration file which may contain a request to change the server.
Moebius uses the following server address: moebius.kaspersky-labs.com:443
For internal interaction, Moebius connects through socket 127.0.0.1:12345. If the socket is not created, Moebius does not start.
The Moebius update package includes the two components:
- Positive update package which is used for detecting spam.
- Negative update package which is used for blocking spam detection.
Moebius only receives the files which are not present in the installed Anti-Spam database but exist on the server. To ensure the correct work of Moebius, Anti-Spam databases must be updated regularly. Otherwise, the file containing the Anti-Spam data to be downloaded can get large.
- Moebius failed to start. Possible cause: port 12345 is busy.
- Moebius has started but it does not work. Possible causes:
- There is no compiled Anti-Spam database from which Moebius can get the configuration file with the addresses of the Moebius servers and the certificate for checking their keys.
- No connection to the Moebius server.
- The Anti-Spam database is out of date (no updates for more than 24 hours). Update the Anti-Spam database.
