This chapter explains how to run the Co:Z Launcher, based on the user's configured authentication mechanism. Authentication with the remote system must be set up so as not to require any user interaction. There are three ways to do this with OpenSSH:
Use the
SSH_ASKPASSenvironment variable to point to a program that will read a password.Use an OpenSSH public/private keypair.
Use a RACF Digital Certificate.
For details on these three authentication options, see Appendix A, Client Authentication Mechanisms. Note that instructions in this appendix must be followed in order to run the examples described below.

Co:Z toolkit samples as member RUNLNCHP
