Telnet Server

The telnet server works optimally for most installations. It accepts logins from a variety of clients, including the telnet

clients shipped with Windows 2000, Windows NT, Windows 95, and Windows 98, as well as a variety of character mode

terminal clients from virtually any operating system. In addition, it can be configured to meet specific site requirements

such as improving security, simplifying logins, and supporting stream or console mode.

Authentication

The SFU telnet server supports Windows NT LAN Manager (NTLM) for authentication of client logins. NTLM allows users to

be automatically authenticated to the telnet server based on their Windows NT login. This makes using telnet completely

transparent to users, while ensuring that clear text passwords do not pass over the network. NTLM must be supported on

the client side of the login as well, however.

When users are logged in to a system that is using NTLM login, they are restricted to local drives on that system. If they

need to map network resources, they can do so by explicitly mapping with full credentials.

Administration

The telnet server is administered using the SFU MMC snap-in or the tnadmin program.

The options available are:

Authentication gives you the choices of NTLM and Username/Password.

Auditing enables you to set event logging to a separate log file, or the event log, and set what events to log.

Server Settings enables you to set the following options:

Maximum number of simultaneous connections

Maximum number of failed login attempts

Map <Alt> key to <Ctrl><A>

Telnet port

Mode of Operation allows you to select Console or Stream.

Default Domain Name is the domain name that is automatically added to the login username. The default
