# kx(1)

securely forward X conections

## NAME

**kx** – securely forward X conections

## SYNOPSIS

*kx* \[**-l** *username*\] \[**-k**\] \[**-d**\] \[**-t**\] \[**-p** *port*\] \[**-P**\] *host*

## DESCRIPTION

The **kx** program forwards an X connection from a remote client to a local screen through an authenticated and encrypted stream.  Options supported by **kx**:

- **-l**

  Log in on the remote the host as user *username*.

- **-k**

  Do not enable keep-alives on the TCP connections.

- **-d**

  Do not fork. This is mainly useful for debugging.

- **-t**

  Listen not only on a UNIX-domain socket but on a TCP socket as well.

- **-p**

  Use the port *port*.

- **-P**

  Force passive mode.

This program is used by **rxtelnet** and **rxterm** and you should not need to run it directly.

It connects to a **kxd** on the host *host* and then will relay the traffic from the remote X clients to the local server.  When started, it prints the display and Xauthority-file to be used on host *host* and then goes to the background, waiting for connections from the remote **kxd**.
