# Remote Daemon

In most cases, programs use a local daemon, running on the same host as the program. Certain situations require a remote daemon, for example:

| • | The program runs on a laptop computer that is not directly connected to the network. Instead, the laptop connects to a workstation on the network, and the daemon runs on that workstation.

| • | The program connects to a network at a remote site.

For remote daemons, specify two parts (introducing the remote host name as the first part):

| • | Remote host name.

| • | TCP socket number.

For example: `"purple_host:6555"`.

Once again the communication type and socket number in the `daemon` parameter of the transport creation call must match those given to `rvd` through its `-listen` parameter. However, the `-listen` parameter still receives only a two-part argument—without a remote host name.

When a client specifies a remote daemon that is not present, the client does not auto-start a daemon in that remote location.

Note | For a general overview, see Direct Communication on page 91 in TIBCO Rendezvous Concepts.

## Barring Remote Connections

A Rendezvous daemon or routing daemon can prohibit connections from remote programs by specifying `-listen "127.0.0.1"`. The special network address `127.0.0.1` represents the local host, so this parameter specifies that only local programs may connect.

This configuration is especially important when a routing daemon runs on a firewall computer.
