The configuration management server handles the SSH connection between the configuration management server and the router. Therefore, the SSH software must be installed locally on the configuration management server. If the application uses the NETCONF Perl module provided by Juniper Networks, no further action is necessary. As part of the installation procedure for the Perl module, you install a prerequisites package that includes the necessary SSH software. If the application does not use the NETCONF Perl module, obtain the SSH software and install it on the computer where the application runs. For information about obtaining and installing SSH software, see http://www.ssh.com and http://www.openssh.com.
