# twoftpd-auth(1)

TwoFTPD authentication front-end

## NAME

twoftpd-auth - TwoFTPD authentication front-end

## SYNOPSIS

**twoftpd-auth** **cvmodule** **twoftpd-xfer**

## DESCRIPTION

**twoftpd-auth** reads a username and password from the network and authenticates them using the CVM module **cvmodule**. If the authentication succeeds, it sets the environment variables **UID**, **GID**, **HOME**, and **USER** to the user's UID, GID, home directory, and login name respectively, and then executes **twoftpd-xfer**. It also sets **GROUP** if the CVM reports a group name, and **AUTHENTICATED** to **1** (**twoftpd-auth** and **twoftpd-xfer** look for this variable to determine what startup banner code to use).

## ENVIRONMENT

- **AUTH\_ATTEMPTS**

  The maximum number of authentication attempts to allow before dropping the connection.

- **AUTH\_TIMEOUT**

  The maximum number of seconds to wait for successful authentication.

- **LOGINBANNER**

  If set, the contents of this variable will be sent as extra responses before the user logs in.

- **TIMEOUT**

  The maximum number of seconds to wait for command input.
