NEW LICENSE

The new C-Kermit license (FIRST DRAFT!) is in the file COPYING.TXT and also
seen when you type "version" or "copyright" at the C-Kermit> prompt.  The
intention is to allow C-Kermit to be included with "free" operating systems
like Linux, FreeBSD, NetBSD, etc, in the regular OS distribution.

PSEUDOTERMINAL CONTROL

This new feature, available only in UNIX (most, but not all, UNIX versions)
allows C-Kermit to control any program that you can run at your terminal.
Unlike the PIPE command (introduced in earlier Betas), which was restricted to
those commands or programs that use standard input and output, the new PTY and
SET HOST /PTY commands can control any text-mode program at all.  This allows
C-Kermit to:

 . Make connections it could not make before -- ssh, tn3270, and so on --
   with full file-transfer, character-set translation, and scripting
   available, just as on its own built-in connection types.

 . Script local programs such as ftp, your mail client, lynx, even (with
   sufficient ingenuity) editors like Emacs and Vi, not to mention the
   many command system-administration tools.

In short, C-Kermit can now take advantage of the capabilities of other
programs in a way that can be fully automated, without having to code these
capabilities into C-Kermit itself.  In the case of ssh, for example, this
allows C-Kermit to make "secure" connections without having to incorporate the
patented, export-restricted SSH code or algorithms.

SECURITY

The experimental SSL/TLS features have been finalized after months of
discussions with IETF working groups, submission of Internet Drafts, and
cooperation with other workers in this area:

 . Uses OpenSSL 0.9.4 to provide SSL and TLS protocol.
 . Supports SSLv3 and TLSv1 connections for use with HTTP script commands.
 . Implements the IETF TN3270 Working Groups' Telnet START_TLS
   option for negotiating secure telnet connections.  START_TLS
   may be used to provide an encrypted channel over which
   Kerberos, Secure Remote Password, and other authentication
   methods may then be used for end user authentication.
 . Implements Tim Hudson's Telnet AUTH SSL suboption.
 . Supports both client and server side protocols.
 . Server supports client certificate verification and revocation.
   certificate to userid mapping functionality may be customized.
 . ~/.tlslogin files may be used to provide automated login to accounts.
 . Client supports server certificate verification and revocation.
 . Kermit's START_TLS support is fully compatible with the Unix Telnet[d]
   START_TLS implementation developed by Peter Runestig which is available
   for download at ftp://ftp.runestig.com/pub/starttls/.

SSL/TLS and other security options are available only in the USA and Canada
due to USA export law.

HTTP CLIENT OPERATIONS

C-Kermit can now contact and interact directly with Web servers using HTTP 1.0
protocol.  Now you can use C-Kermit's automation features to manage websites;
get files, put files, delete files, get and examine indexes or other
information, post forms-filling data, and so on, and this can be done in a
secure manner by using SSL/TLS (available only in the USA and Canada).

DOCUMENTATION, ETC

All the new features are documented in the ckermit2.txt file, plus:

 . iksd.txt, now including complete information about the IKSD database.
 . security.txt, which is current with Beta.11.
 . telnet.txt, ditto.

Thanks to those who sent in binaries, bug reports, and suggestions so far.
If you can can do the same for Beta.11, I'd appreciate it!  And of course
report any problems to:

  [e-mail]

Filenames of new binaries start with ck?196b11 (where ? is u, v, d, etc).

Thanks!
