Connecting to the JUNOScript Server

For a client application to connect to the JUNOScript server and open a session, you must first satisfy the prerequisites described in Prerequisites for Establishing a Connection.

When the prerequisites are satisfied, an application written in Perl can most efficiently establish a connection and open a session by using the JUNOScript Perl module provided by Juniper Networks. For more information, see Writing Perl Client Applications.

A client application that does not use the JUNOScript Perl module connects to the JUNOScript server by opening a socket or other communications channel to the JUNOScript server machine (routing platform), invoking one of the remote-connection routines appropriate for the programming language and access protocol that the application uses.

What the client application does next depends on which access protocol it is using:

• If using the clear-text or SSL protocol, the client application does the following:
  1. Emits the initialization PI and tag, as described in Emitting the Initialization PI and Tag.
  2. Authenticates with the JUNOScript server, as described in Authenticating with the JUNOScript Server.
• If using the SSH or Telnet protocol, the client application does the following:
  1. Uses the protocol’s built-in authentication mechanism to authenticate.
  2. Issues the junoscript command to request that the JUNOScript server convert the connection into a JUNOScript session. For a C programming language example, see Writing C Client Applications.
  3. Emits the initialization PI and tag, as described in Emitting the Initialization PI and Tag.
