Following the automatic reboot or the manual IPL of the installed Red Hat Enterprise Linux operating system, you can log on to the system via ssh. Note that the only place from which you can log in as root is from the 3270 terminal or from other terminal devices listed in /etc/securetty.

The first time you start your Red Hat Enterprise Linux system in a graphical environment, you can use FirstBoot to guide you through Red Hat Enterprise Linux configuration. Using this tool, you can set your system time and date, install software, register your machine with Red Hat Network, and more. FirstBoot lets you configure your environment at the beginning, so that you can get started using your Red Hat Enterprise Linux system quickly.
