The RARP Daemon (in.rarpd)
The /etc/sbin/in.rarpd daemon provides Ethernet-address-to-IP-address
resolution. When a RARP request is received, the in.rarpd program
attempts to determine the IP address assigned to the specified Ethernet
address. The look up procedure consists of first looking up the Ethernet
address to obtain the hostname of the system, and then looking up the host-
name to determine its IP address.
The procedure used to look up the hostname (based on Ethernet address)
is determined by the configuration of the ethers keyword in the name
service switch ( /etc/nsswitch.conf ) file. It can be obtained from NIS
(ethers.byaddr map), NIS+ (ethers table), or the /etc/ethers file. See
ethers(4) for the format of the /etc/ethers file.
The procedure used to look up the IP address (based on the obtained host-
name) is determined by the configuration of the hosts keyword in the name
service switch ( /etc/nsswitch.conf ) file. It can be obtained from DNS, NIS
( hosts.byname map), NIS+ (hosts table), or the /etc/hosts file. See hosts(4)
for the format of the /etc/hosts file.
The TFTP Daemon (in.tftpd)
The /usr/sbin/in.tftpd daemon provides a simple method for SPARC
install clients to obtain the boot image from the install/boot server using the
Trivial File Transfer Protocol (TFTP). Unlike the standard File Transfer
Protocol (FTP), TFTP does not require user authentication (account name
and password) to access files. The boot images are typically stored under the
/tftpboot directory.
The NFS Server Daemon (nfsd)
The /usr/lib/nfs/nfsd daemon provides network access to the Solaris 9
distribution files via NFS. These files are identified by the boot parameters
provided by the rpc.bootparamd daemon.
The Boot Parameter Server Daemon (rpc.bootparamd)
The /usr/sbin/rpc.bootparamd daemon provides NFS share names and
other information necessary to boot install clients. The source of the infor-
mation is determined by the configuration of the bootparams keyword in the
name service switch ( /etc/nsswitch.conf ) file. It can be obtained from NIS
( bootparams map), NIS+ ( bootparams table), or the /etc/bootparams file. See
bootparams(4) for the format of the /etc/bootparams file. The “Need to
Know More” section includes more information on section 4 of the user
manual.
