Hyperglobal Variables

Using hyperglobal variables, data can be encrypted and communicated in real-time between multiple servers via Antcas Hub.

Note: Each individual variable is subject to licensing requirements as the service is provided by Antcas.

The communication takes place outbound via HTTPS or TCP/IP over port 443. The server needs an internet connection to https://hub.antcas.com. No firewall configuration is required as the connection goes from inside to outside.

Prerequisites

The server must have an internet connection. Additionally, the server must be in the same group (ID) in the portal. See Remote Access.

Note: Only one gateway can be activated per server at a time.

Communication

The communication is established between servers using a variable under Installation in the corresponding "Hyperglobal Variables" interface. This must be subscribed to in the interface. That is, the state is read by other servers or via the portal. The last written value counts. Once the value has been transmitted to all servers, an ACK signal is issued. If the variable is received from the portal, RECV is signaled and simultaneously the value AGE is set to the timestamp of the portal.

For a value to be subscribed to, it simply needs to be created. After that, it should be renamed to a meaningful name. Communication then takes place based on name equality. That is, exactly the same names must be used on all servers.

Variable Name

The variables should have a unique format. For example:

Sturmwarnung Bern

All invalid characters are automatically converted and any leading or trailing spaces are removed.

The following characters are removed:

? !

The following characters are converted to a _ (underscore):

[SPACE] $ / \ : = - , ;

Monitoring of Servers

When establishing the connection, the list of servers is imported from the portal. This way, other servers can be monitored.
