Connecting to the Host System - VT

VT Define New Connection

Prior to establishing a host system connection, BlueZone VT users must set Session Configuration parameters.  Session configuration consists of:

• Selecting an existing or Defining a new Connection Type and configuring its connection settings.

This section deals with Defining a New Connection.  The BlueZone VT Define New Connection property sheet consists of a Connection, Firewall and Security tabs.

Connection Tab

Telnet Connection ----

• Connection Name: A unique name used to identify this collection of Connection settings.

• Host Name/Address: Specifies the computer name (in Internet format) or the IP address (in dotted decimal format) of the VT server.  An IP address is the preferred format, eliminating the requirement for domain name resolution, resulting in a faster connection time and recovery if the name cannot be resolved.

• TCP Port: Specifies the TCP port number to which to connect. The default is 23.

• Backup Host: Specifies the backup host to which BlueZone will connect if the primary host is not available. Backup hosts are selected from the Connection List.
