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. However, NTLM must be

supported on the client side of the login as well.

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 following options are available:

Authentication gives you the choice of NTLM or Username/Password.

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

Server Settings allows you to set the following options:

Maximum number of simultaneous connections.

Maximum number of failed login attempts.
