                Callback for Linux, release 2.04
                ================================

We just uploaded to ftp.icce.rug.nl (directory pub/unix), sunsite.unc.edu
and tsx-11.mit.edu the latest release of our callback programs:
version 2.04.

The callback programs can be used to setup a callback-system, where a
linux-computer acting as a call-in site calls another computer, from which
a modem-connection is requested.

Apart from the obvious financial aspects (i.e., if you live in that part of
the world where you have to pay for (local) phonecalls), callback provides
enhanced security: entry to the server is only granted from specified
callback phonenumbers.

The changes compared to the former upload (2.00) are:

    1.Modification of cb's usage info so that it displays a minimal usage
        info even if the callback.setup file isn't available.

    2 Defining the callback.setup entry 'diallogfile:', logging the
        times, targetnames and phonenumbers that are called back.
     
    3 The display of the 'extra', 'direct' and normal callback destinations
        can be controlled from the callback.setup file. By default the 'extra'
        and 'direct' entries are not displayed in the lists cblogin presents.
        The 'cb list' command always displays all entries. In the
        callback.setup defaults section, the keywords
            extra
            direct
        and
            nodestinations
        can be used to control, respectively, the display of 'extra' and
        'direct' destinations, and the suppression of the display of the
        'normal' destinations.

    The callback documentation is also obtainable from ftp.icce.rug.nl,
(directory /pub/http), and can be inspected from our WWW-server
http://www.icce.rug.nl.
