Setting Up a UNIX Boot Server

To support network booting, you need to set up a UNIX workstation on the

network. This chapter describes what you need to do at the UNIX workstation to

prepare for booting an ASN over the network.

When a router boots over the network, it gets necessary startup ﬁles from a UNIX

server. When the ASN uses EZ-Install or Netboot, the server supplies

conﬁguration ﬁle and/or software image ﬁle pathnames using Boot Protocol

(BOOTP). The ASN then retrieves the ﬁles using Trivial File Transfer Protocol

(TFTP). When the ASN uses Directed Netboot, it already knows the pathnames of

the ﬁles it needs and retrieves the ﬁles directly from the server using TFTP.

To conﬁgure EZ-Install or Netboot, complete the steps in both “Setting Up a

BOOTP Server” and “Setting Up a TFTP Server.” To conﬁgure Directed Netboot,

complete the steps in “Setting Up a TFTP Server.”

Setting Up a BOOTP Server

To support EZ-Install or Netboot, an ASN needs a network connection to a

BOOTP server. You conﬁgure a UNIX workstation as a BOOTP server by

• Setting up BOOTP sockets

• Conﬁguring BOOTPD (the BOOTP daemon)

On Sun workstations, you must ﬁrst copy the BOOTPD program to the

appropriate directory.

Note: A daemon is an unattended process (that is, one that runs in the

background). An application typically calls up a daemon to perform a

standard routine or service (in this case, BOOTP).
