Your windows account needs to be memeber of administrators or power users to install services.



KTS starts as SSH server, how to make it telnet server
Open KTS setup. Set [KTelnetd]:port to 23 ( default telnet port ) and [KTelnetd]:use_ssh to 0. Restart the server and it will act as telnet server.



I need to use the <ALT> key in the host application. How to send it?
Use the <CTRL> + <A> combination instead. If your client supports key mapping, you can map the <ALT> key to <CTRL> + <A>, and use it directly.



How do I create a KpyM telnet account?
You don't have to create an account, instead use the winnt user/pass to login.



My computer is in domain. Where to type it ?
KTS does not display a domain prompt. Instead use a UPN( user principal name ) login name. The format is: someone@my_domain (as for an e-mail address). If you want to use a default domain specify [KTerm]default_domain parameter through KTS setup and use your username only to login.


We do require installing KpyM Telnet SSH Server on many machines and we'd like to get rid of the nag screen, what the terms of a single license are - $35/site or $35/machine?
Once you get a registration key you can use it on every computer you have access to. In short, you can treat it as a much relaxed site license.


In the log directory I found the file XXXXXXXXXXXX.err. What's that?
These are error log files. Please e-mail the file to support@kpym.com. It is safe to delete these files.



You say that KTS is open source, but I can't find the source anywhere?
When installing KTS mark the 'Source Files' checkbox, it will extract the sources together with the binaries.



Which are the command line parameters of telnetd.exe?
telnetd.exe -setup         enter setup mode
telnetd.exe -install       install KTS service
telnetd.exe -uninstall     uninstall KTS service
telnetd.exe -start         start KTS service
telnetd.exe -stop          stop KTS service


Can the server pass control characters to the host application?
Yes, except for the following characters:
<CTRL> + <A> - reserved for the ALT key
<CTRL> + <Q> - reserved for KTS
<CTRL> + <C> - not supported in some applications



Can I use the function keys ( F1 - F12 ).
Yes, since your telnet client supports it.



I want to allow/forbid certain users from loging into KTS. Is it possible?
Yes, use the [KTerm] allowed_login_list/forbidden_login_list parameters
If you fill allowed_login_list only the users that are in that list will be allowed to telnet to your host.
If you fill forbidden_login_list all users except these in the forbidden list will be allowed.
Note that you have to enclose the users with ':' character
For example to allow access ONLY to the users 'foo' and 'bar' set allowed_login_list to:
allowed_login_list = :foo:bar:
( note there is ':' on the both sides of the user names )



How many users can connect to my server with your software? By default there is 255 simultaneous connections limit, but it has never been tested that far.



I telnet KTS host and then I telnet another machine, but I have some screen display problem.
This problem is partially fixed since v1.12, however some display problems still exist. I'm working on fixing that problem.

Are there any other windows SSH servers?
Yes. Take a look at that list

freeSSHd
freeSSHd, like it's name says, is a free implementation of an SSH server. It provides strong encryption and authentication over insecure networks like Internet. Users can open remote console or even access their remote files thanks to buit-in SFTP server.

WinSSHD
WinSSHD is our SSH Secure Shell 2 server for Windows NT4, 2000, XP, 2003 and Vista. It supports the following SSH services:
Secure remote access via console (vt100, xterm and bvterm supported)
Secure remote access via GUI (Remote Desktop or WinVNC required)
Secure file transfer using SFTP and SCP (compatible with all major clients)
Secure TCP/IP connection tunneling (port forwarding)
You can try out WinSSHD risk-free. To begin, simply download the installation executable - you will find the download links on our download page. After installing, you are free to evaluate WinSSHD for up to 30 days.

Dropbear SSH server and client
Dropbear is a relatively small SSH 2 server and client. It runs on a variety of POSIX-based platforms. Dropbear is open source software, distributed under a MIT-style license. Dropbear is particularly useful for embedded-type Linux (or other Unix) systems, such as wireless routers.

OpenSSH for Windows
OpenSSH for Windows is a free package that installs a minimal OpenSSH server and client utilities in the Cygwin package without needing the full Cygwin installation. This is similar to the package formerly available from NetworkSimplicity. The OpenSSH for Windows package provides full SSH/SCP/SFTP support. SSH terminal support provides a familiar Windows Command prompt, while retaining Unix/Cygwin-style paths for SCP and SFTP.

OpenSSH
OpenSSH is a FREE version of the SSH connectivity tools that technical users of the Internet rely on. Users of telnet, rlogin, and ftp may not realize that their password is transmitted across the Internet unencrypted, but it is. OpenSSH encrypts all traffic (including passwords) to effectively eliminate eavesdropping, connection hijacking, and other attacks. Additionally, OpenSSH provides secure tunneling capabilities and several authentication methods, and supports all SSH protocol versions.

VShell Server
VShell Secure Shell server replaces Telnet and FTP in your IT infrastructure to address your evolving needs for secure network administration and end-user access on Windows and UNIX platforms. Armed with strong encryption, trusted authentication, and data integrity, you can confidently exchange electronic data over public networks. Access control lists (ACLs) and SFTP virtual directories equip administrators with fine-grained control to comply with internal and external security policies. Triggers can automate routine tasks, freeing valuable time for network professionals.

copSSH - OpenSSH for Windows
copSSH is an ssh server and client implementation for windows systems. It is a yet another packaging of portable openssh, cygwin, some popular utilites, plus implementation of some best practices regarding security. You can use COPSSH for remote administration of your systems or gathering remote information in a secure way.
