# emp\_hub(6)

Empire multiplexer

## NAME

emp\_hub - Empire multiplexer

## SYNOPSIS

**emp\_hub** *\[-persistent\] \[-debug\] \[-help\] \[-mirror\] host port localport*

## DESCRIPTION

**emp\_hub** allows multiple clients to simultaneously connect to a single Empire country.  This allows you to use both a fast and a smart client simultaneously.  It also permits multiple corulers to log in at once.

### Parameters

-

  - **host**

  Hostname of the upstream server.

- **port**

  TCP/IP port number the empire server is running on.

- **localport**

  TCP/IP port number the emp\_hub should listen to for incoming client connections.

- *-mirror*

  Copy commands and replies to all clients using new protocols.  Currently only the  **lafe** client is aware of these protocols, though most clients will ignore them.

- *-persistent*

  Normally **emp\_hub** exits after the last client disconnects.  With this option **emp\_hub** does not exit, and will wait for new clients to connect. **emp\_hub** must be killed by the user using the **kill** command.

- *-help*

  Brief usage information.

- *-debug*

  Print lots of messages, including everything sent and received by a client. Useful when debugging either **emp\_hub** , a client, or the server.

## BUGS

Due to the nature of the empire protocol, only one client may have input focus at one time.  If a client pauses at a context sensitive prompt from the server, all other clients will be unable to send data.
