ChorusOS 5.0 Installation Guide

Setting Up RARP Services

RARP service allows the target system to obtain its IP address over the Ethernet from the boot server.

Note -

If /tftpboot exists at boot time, a system running the Solaris operating environment starts the RARP daemon as part of normal system initialization.

The RARP daemon should run on a boot server whose IP network is the same as that of the target. See the TCP/IP and Data Communications Administration Guide and in.rarpd(1M) for details.

To Set Up RARP Services

  1. Check /etc/nsswitch.conf on the boot server for lines starting with ethers:


    $ grep ^ethers /etc/nsswitch.conf

    If the output starts with 

    Then 

    ethers: nis

    For example: 

    ethers: nis [NOTFOUND=return] files

    Proceed to Step 2.

    ethers: files

    For example: 

    ethers: files nis [NOTFOUND=return]

    Proceed to Step 3.

    Something other than the preceding choices 

    Ask your NIS administrator for help.

  2. Verify whether the target is listed in the map ethers.byname:


    $ ypmatch target_hostname ethers

    If the output is 

    Then 
    target_Ethernet_address target_hostname

    Proceed to Step 4.
    Can't match key target_hostname in map ethers.byname. Reason: no such key in map.

    Verify the target Ethernet address, and then proceed to Step 3.

  3. Add the following line to /etc/ethers on the boot server:

    target_Ethernet_address               target_hostname

  4. Start the RARP daemon on the boot server:


    $ su
Password: superuser_password
# /usr/sbin/in.rarpd -a
