If your system doesn't present you with an OBP at boot time, you will either need to press the Stop and A key, or send a break signal via serial console before the system boots an OS. The command for the example /tftpboot is: If the directory you have chosen does not currently exist, it will need to be created with the mkdir command. Additionally, we'll setup the system to run the TFTP daemon with the user and group nobody. This will appear as the root ( /) directory to the clients when requests are received. The directory we will use for this howto will be /tftpboot.

You only need to install one of the TFTP daemons for proper operation.Įach TFTP daemon will need a directory from which to serve files to tftp clients. Here there are two options for a TFTP daemon, net-ftp/atftp and net-ftp/tftp-hpa.

eth0 represents the interface which rarpd should bind to.

-e Do not check for the presence of a boot image, reply if MAC address resolves to a valid IP address using /etc/ethers database and DNS.

The following example is for a host named :įILE /etc/conf.d/local.start /usr/sbin/rarpd -v -e eth0Īn explanation of the above rarpd options (as taken from the man page):

Whitespace delimits the MAC address from the hostname, and each entry should have its own line. The format of /etc/ethers is the MAC address of the NIC the machine will be netbooting and its hostname. This file indicates which hosts rarpd should respond to when a request is seen, and what address to reply with. You will need to setup the /etc/ethers file. Setting up common rarpd elements : /etc/ethers Software Installation And Configuration The reverse ARP daemonĪ reverse ARP daemon is already installed on the system it's part of the net-misc/iputils package.

Once the image is downloaded, the netboot client then boots the image.īased on this overview, we will need to install software for a reverse ARP daemon and a TFTP daemon.

The client then attempts to download a boot image from the RARP server using the TFTP protocol.

A server machine returns a response to the client with the IP address.

Client machine sends out a reverse ARP (RARP) request to get an IP address.

The document assumes that you have an existing Gentoo Linux computer available to act as the netboot server.īoth the netboot server and netboot client will need to be on the same network subnet, as the ARP protocol is typically not forwarded across different network subnets.Ī generic overview of what happens during the netboot process is as follows:

This document will describe how to setup a network booting environment for a Sun Microsystems SPARC or UltraSPARC based computer. This guide is currently very SPARC-centric and expecting that you will be setting up your netboot server on an existing Gentoo Linux machine.
