Writing Junos XML Protocol C Client
Applications

Establishing a Junos XML Protocol Session

Copyright © 2010, Juniper Networks, Inc.
In this section, we offer two examples of using C to create client applications to access
routers, switches, and security devices running Junos OS. The first example shows how
to establish a Junos XML protocol session. The second example, shows how to retrieve
and manipulate device configurations using C.

Accessing and Editing Device Configurations on page 234
The following example illustrates how a client application written in C can use the SSH
or Telnet protocol to establish a Junos XML protocol connection and session. In the line
that begins with the string
(Substitute the command if appropriate.) The
telnet
routine specifies the hostname or IP address of the Junos XML protocol server
execlp
device. The argument is the command that converts the connection to a Junos
junoscript
XML protocol session.
For more information about Junos XML protocol sessions, see "Controlling the Junos XML
Management Protocol Session" on page 25.
