TcpHost — specify which hosts can connect to Interchange server running in Inet mode
The TcpHost
directive defines a list of hostnames whose
connections to the Interchange Inet socket will be accepted.
This effectively allows or denies access to all catalogs running on the
corresponding Interchange server.
It's important to note that the directive does not support wildcards or anything, it only accepts plain list of space-separated IPs or hostnames.
