Quote from SUN for Solaris 9 and Solaris 10 DHCP

Quote:

For Solaris 9 systems:

1. Edit the file /etc/init.d/inetsvc and change the line that reads the following: hostname='/sbin/dhcpinfo Hostname' to

#hostname='/sbin/dhcpinfo Hostname'

hostname='/usr/bin/cat /etc/nodename'

2. Create a executable script in /etc/rcS.d directory for example S31myhost

and add the following line :

hostname dhcpclient1

Note: dhcpclient1 is example of a hostname.

3. Next, Follow the same procedure as for Solaris 10 which is listed below.

For Solaris 10 systems:

1. Edit the /etc/default/dhcpagent file and change the line that reads the following:

#REQUEST_HOSTNAME=no

to

REQUEST_HOSTNAME=no

2. Edit the /etc/hostname.interface(example of dhcp interface is hostname.hme0) file

and add the hostname to that file.

3. Edit the /etc/nodename file and add the hostname to that file as well.

4. Edit the /etc/hosts file and add the loghost and hostname. See example below:

# # Internet host table # 127.0.0.1 localhost loghost dhcp ip dhcpclient1 # Added by DHCP

5. Reboot the DHCP Client

nodename

nodename(4)							   File Formats 						       nodename(4)

NAME

       nodename - local source for system name

SYNOPSIS

       /etc/nodename

DESCRIPTION

       When  a	machine is standalone or its IP address is configured locally, the /etc/nodename file contains the system name. By convention, the
       system name is the same as the hostname associated with the IP address of the primary network interface, for example, hostname.hme0.

       If the machine's network configuration is delivered by the RPC bootparams protocol, the /etc/nodename file is not used, as the system  name
       is delivered by the remote service.

       Given a system name value, regardless of source, the uname utility invoked with the -S option is used to set the system name of the running
       system.

       If the machine's network configuration is delivered by the DHCP protocol, the /etc/nodename file is used only if the DHCP server  does  not
       provide a value for the Hostname option (DHCP standard option code 12).

       A system name configured in /etc/nodename should be unique within the system's name service domain in order to ensure that any network ser-
       vices provided by the system will operate correctly.

       Given a system name value, regardless of source, the uname utility invoked with the -S option is used to set the system name of the running
       system.

EXAMPLES

       Example 1: Syntax

       The syntax for nodename consists of a single line containing the system's name. For example, for a system named myhost:

       myhost

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWcsu			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       nis+(1), uname(1), named(1M), ypbind(1M), attributes(5)

NOTES

       The nodename file is modified by Solaris installation and de-installation scripts.

SunOS 5.10							    9 Feb 2004							       nodename(4)
