CHAPTER 12 User accounts

12.2 Admittance - login procedure

Under SunOS 4.1.X init creates a process for each terminal port defined within /etc/ttytab. For each hardwired line it starts a getty process. For network ports init starts the inetd daemon process to monitor for telnet, ftp, etc. logins. When the user logs out init detects this event and restarts the getty process. Similarly, the getty process is used by IRIX, Digital UNIX, and Ultrix.

For SunOS 5.X init uses the Service Access Facility to control system access. We will look at this service in a latter chapter.
