Booting a RIS Client
You must register a RIS client on the RIS server before you can use RIS to
install the operating system on the RIS client. If you use RIS to install the
operating system on a client, the client must boot across the network by
issuing a BOOTP request. This chapter includes the following topics:
• Describing remote boot files and daemons (Section 5.1)
• Explaining the remote boot process flow (Section 5.2)
5.1 Remote Boot Files and Daemons
Several files and daemons are associated with booting a RIS client over the
network. This section includes the following topics:
• The inetd internet daemon and its configuration file, inetd.conf
(Section 5.1.1)
• The internet boot protocol (BOOTP) joind daemon (Section 5.1.2)
• The /etc/bootptab file (Section 5.1.3)
• The TFTP daemon tftpd (Section 5.1.4)
