General-Purpose Telnet Server for Windows NT Platforms

The Ataman TCP Remote Logon Services (ATRLS) are a collection of Windows NT servers that allow your users to remotely connect to a host Windows NT system running one of the ATRLS services. The telnetd service allows users with telnet clients to remotely logon to a host computer. The daemon offers full support for the telnet protocol specified in the RFC 854. The rlogind service performs a function similar to the telnet daemon but allows users with rlogin clients to remotely logon to a host. The rlogin server offers full support for the rlogin protocol specified in the RFC 1282.

If the client for either of these two services supports ANSI terminal escape sequences (examples are clients with VT100, VT220, xterms, or xterm support), the user has the ability to run full-screen console apps like text editors on the ATRLS host. Additionally, color support is provided by clients that implement ANSI-BBS-style escape sequences. When connecting with either of the two services users are presented with a primarily Unix-based interface. If you've accessed telnet or rlogin sites before, you won't have any problems working with ATRLS; otherwise, you might want to brush up on basic Unix commands before setting up the services.

ATRLS presents several additional benefits to both the client and the host. First, each remote user executes in their own security context. ATRLS also runs as Windows NT system service, meaning that no one needs to be logged onto the console in order for a user to connect to one of the ATRLS services. Administrators are presented with an easy to use configuration control panel and an extensive set of features for administering the services. And in addition to the telnetd and rlogind services, ATRLS also includes rexecd and rshd services, which bring the rexec and rsh protocols found on many Unix systems to Windows NT.

In addition to the Intel and Alpha versions of ATRLS for Windows NT, Ataman software has also released the Ataman RSHD Service (ARSHD) for Windows 95, which offers full support for the TCP Remote Shell Host (RSH) protocol. The $38 ARSHD allows users to remotely start programs on host Windows 95 ARSHD systems. The server is also packaged with a rsh client program that users can use to access the ARSHD server. While ARSHD doesn't offer the same functionality as the Windows NT ATRLS, it is an attractive solution for Windows 95 users who are looking for an efficient remote service.

Help for both of the programs is available in the form of comprehensive user manuals that are packaged with the services. Registered users also have access to free e-mail technical support via the support@ataman.com address. Overall, ATRLS and ARSHD offer an extensive collection or remote services, one or more of which is sure to meet your needs. Commercial remote access programs like LapLink, PCAnywhere, and CarbonCopy offer many of the same features as the ATRLS services, and they do so with a more intuitive and attractive interface. But for advanced users who place a premium on efficiency, the $68 ATRLS is a solid choice.

Pros: Relatively inexpensive, solid set of remote services, easy to use, Windows NT/9x support
Cons: Lacks the ease of use (from the client end) of commercial programs like LapLink
New: Command-line configuration capabilities, RSHD services, ANSI color support

New in v2.5: PromptAfterBannerAfterLogon option, fixed auseradm and aconfig to account for variable settings, added missing eventlog message for LogonUser failure, bug fixes
