Subject: Request for Beta Testers: Internet Kermit Service for Windows

The Kermit Project would like to announce the start of a public
testing period for a new (to be free) Internet Kermit Service for
Microsoft Operating Systems (Windows 95/98/NT4/2000).
An Internet Kermit Service <http://www.kermit-project.org/cuiksd.html>
provides both anonymous and authenticated access to file systems
of a host onto which it is installed. The IKS is an alternative
to FTP that provides all of the advantages of the Kermit file transfer
protocol and the Kermit Script programming language; works across
multiple firewalls; Network Address Translators; and multiple
transports (e.g. dialup terminal server to IP; or LAT to IP;
or NetBEUI to IP; or IPX to IP; ...)
The IKS for Windows can be used with or without Kermit 95 installed
on the machine. The IKS can be used with any Telnet client that
supports Kermit file transfer protocol.
End user authentication may be performed in one of the following
methods:
. username (domain/user) and password prompts
The user is authenticated against the local machine (if no domain
is specified) using LogonUser() or the NTLM SSPI. When TLS is
supported by the client and server, the username and password
will be transmitted over a secure connection.
Anonymous access is provided using the "GUEST" account on the
local machine.
. Kerberos 4 or Kerberos 5
When MIT Kerberos for Microsoft Operating Systems is installed
with appropriate keytabs for the local machine, end users can
authenticate to the IKS using Kerberos 4 or Kerberos 5. It is
currently required that the Kerberos principal name match the
name of the end user on the local machine or in the default Domain.
No principal to userid translation functions are currently
supported.
. Secure Remote Password
If TPASSWD and TPASSWD.CONF files are available on the local
machine, the users listed in the TPASSWD file may authenticate
to the IKS using the assigned SRP password. It is currently
required that the SRP userid match the name of the end user on
the local machine or in the default Domain. No SRP userid to
Windows userid translation functions are currently supported.
. X.509 client certificates
Functions are provided to allow for the verification of X.509
client certificates and for customized mappings from a certificate
to a userid using a DLL provided by the host administrator.
. NTLM
If both the client is running on a Windows system and it
supports the NTLM Telnet Authentication method, NTLM can be
used to authenticate the end user to the IKS.
When used on Windows NT or Windows 2000, the IKS may be installed
as a Service which runs independent of the end user logged into the
machine. Access to files and directories is controlled by the
privileges assigned to the account and the associated ACLs when the
file system is NTFS.
When the IKS is installed on Windows 95/98 or the file systems
are FAT16 or FAT32, the entire file system of the machine is accessible
to the logged in user since the operating system and/or file systems
do not support ACLs.
The following features are available only when used with a licensed
Kermit 95:
. secure sessions using Transport Layer Security for privacy and
data integrity (even with anonymous logins)
. client authentication via X.509 end user certificates
. encrypted sessions when Secure Remote Password, Kerberos 4, or
Kerberos 5 are being used for end user authentication
. Xmodem, Ymodem, Ymodem-G, and Zmodem file transfer protocols
We are looking for testers on Windows 95/98, NT, and 2000 regardless
of whether or not you are currently using Kermit 95. If interested,
please send e-mail to
mailto:kermit-support@columbia.edu
with the Subject
"IKS Windows Tester"
Please specify:
. the operating system on to which you will be installing the IKS
. which telnet clients you will be using with the IKS
. whether or not you own Kermit 95 and if you have the Encryption
patch installed.
