Non-Kermit File Transfer
You can also use C-Kermit to transfer files with FTP or HTTP Internet
protocols; see below.
.sp
On a regular serial or Telnet connection where the other computer
doesn't support Kermit protocol at all, you have several options. For
example, if your desktop communications software supports Zmodem, use
"rz" and "sz" on the host rather than Kermit. But if Kermit is your
desktop software, and you are using it to make calls or network
connections to other computers that don't support Kermit protocol (or
that don't have a good implementation of it), then if your computer
also has external X, Y, or Zmodem programs that are redirectable,
Kermit can use them as external protocols. HELP SET PROTOCOL for
details.
.sp
You can also capture "raw" data streams from the other computer with
LOG SESSION (HELP LOG and HELP SET SESSION-LOG for details), and you
can upload files without any protocol at all with TRANSMIT (HELP
TRANSMIT, HELP SET TRANSMIT).
.SH KERMIT'S BUILT-IN FTP AND HTTP CLIENTS
Kermit's FTP client is like the regular Unix FTP client that you're used
to, but with some differences:
.TP
\(bu
It has lots more commands and features.
.TP
\(bu
Each FTP command must be prefixed with "ftp", for example "ftp open",
"ftp get", "ftp bye", etc (this is not strictly true, but until you're
more familiar with it, it's best to follow this rule).
.TP
\(bu
Commands like "cd", "directory", etc, execute locally, not on the
server. Use "ftp cd", "ftp dir", etc, to have them act on the server.
.TP
\(bu
You can have an FTP session and a regular Kermit serial or Telnet
session open at the same time.
.TP
\(bu
FTP sessions can be fully automated.
.PP
Pending publication of the next edition of the manual, the Kermit FTP
client is thoroughly documented at the Kermit Project website:
.sp
  http://www.columbia.edu/kermit/ftpclient.html
.sp
You also can use HELP FTP and HELP SET FTP to get descriptions of Kermit's
FTP-related commands.
.PP
The HTTP client is similar to the FTP one, except you prefix each command
with HTTP instead of FTP: HTTP OPEN, HTTP GET, HTTP PUT, HTTP CLOSE, etc.
Type HELP HTTP for details, or visit the to view the manual supplements.
HTTP connections can be open at the same time as regular serial or Telnet
connections and FTP connections. So Kermit can manage up to three types
connections simultaneously.
.SH INTERNET KERMIT SERVICE
C-Kermit can be configured and run as an Internet service (called IKSD),
similar to an FTP server (FTPD) except you can (but need not) interact with
it directly, plus it does a lot more than an FTP server can do. The TCP
port for IKSD is 1649. It uses Telnet protocol. C-Kermit can be an Internet
Kermit Server, or it can be a client of an IKSD. You can make connections
from C-Kermit to an IKSD with any of the following commands:
.sp
.nf
  telnet foo.bar.edu 1649
  telnet foo.bar.edu kermit   ; if "kermit" is listed in /etc/services
  iksd foo.bar.edu
.fi
.sp
The IKSD command is equivalent to a TELNET command specifying port 1649.
For more information about making and using connections to an IKSD, see:
.sp
  http://www.columbia.edu/kermit/cuiksd.html
.sp
You can run an Internet Kermit Service on your own computer too (if you are
the system administrator). For instructions, see:
.sp
  http://www.columbia.edu/kermit/iksd.html
.SH SECURITY
All of C-Kermit's built-in TCP/IP networking methods (Telnet, Rlogin, IKSD,
FTP, and HTTP) can be secured by one or more of the following IETF-approved
methods:
.PP
\(bu	MIT Kerberos IV
.br
\(bu	MIT Kerberos V
.br
\(bu	SSL/TLS
.br
\(bu	Stanford SRP
.PP
For complete instructions see:
.PP
  http://www.columbia.edu/kermit/security.html
.PP
And as noted previously, you can also make SSH connections with C-Kermit if
you already have an SSH client installed.
.SH ALTERNATIVE COMMAND-LINE PERSONALITIES
When invoked as "kermit" or any other name besides "ftp" or "telnet",
C-Kermit has the command-line options described above in the OPTIONS
section. However, if you invoke C-Kermit as "telnet" or "ftp", it changes
its command-line personality to match. This can be done (among other ways)
with symbolic links (symlinks). For example, if you want C-Kermit to be
your regular Telnet client, or the Telnet helper of your Web browser, you
can create a link like the following in a directory that lies in your PATH
ahead of the regular telnet program:
.sp
  ln -s /usr/local/bin/kermit telnet
.sp
Now when you give a "telnet" command, you are invoking Kermit instead, but
with its Telnet command-line personality so, for example:
.sp
  telnet xyzcorp.com
.sp
Makes a Telnet connection to xyzcorp.com, and Kermit exits automatically
when the connection is closed (just like the regular Telnet client). Type
"telnet -h" to get a list of Kermit's Telnet-personality command-line
options, which are intended to be as compatible as possible with the
regular Telnet client.
.PP
Similarly for FTP:
.sp
  ln -s /usr/local/bin/kermit ftp
.sp
And now type "ftp -h" to see its command-line options, and command lines
just like you would give your regular FTP client:
.sp
  ftp xyzcorp.com
.sp
but with additional options allowing an entire session to be specified on
the command line. Finally, if Kermit's
first command-line option is a Telnet, FTP, IKSD, or HTTP URL, Kermit
automatically makes the appropriate kind of connection and, if indicated by
the URL, takes the desired action:
.TP
kermit telnet:xyzcorp.com
Opens a Telnet session
.TP
kermit telnet://[e-mail]
Ditto for user olga
.TP
kermit ftp://[e-mail]/public/oofa.zip
Downloads a file
.TP
kermit kermit://kermit.columbia.edu/kermit/f/READ.ME
Ditto for IKSD
.TP
kermit iksd://kermit.columbia.edu/kermit/f/READ.ME

.SH LICENSE
C-Kermit has an unusual license, but a fair and sensible one since the
Kermit Project must support itself out of revenue: it's not a BSD license,
not GPL, not Artistic, not commercial, not shareware, not freeware. It can
be summed up like this: if you want C-Kermit for your own use, you can
download and use it without cost or license (but we'd appreciate it if you
would purchase the manual). But if you want to sell C-Kermit or bundle it
with a product or otherwise distribute it in a commercial setting EXCEPT
WITH AN OPEN-SOURCE OPERATING SYSTEM DISTRIBUTION such as Linux, FreeBSD,
NetBSD, or OpenBSD, you must license it. To see the complete license, give
the LICENSE command at the prompt, or see the COPYING.TXT file distributed
with C-Kermit 7.0 or later, or download it from
