DHCP JumpStart only supported on Intel and Ultra systems. Ultra systems must have a PROM version of at least 3.25.
The add_install_client with the “d option specifies that the JumpStart client is using DHCP.
Create symbols to provide the DHCP server with the configuration information the client needs. The symbols are then added to the macro that executes when the client starts DHCP. Symbols and macros are manipulated using dhcpmgr (GUI utility) or dhcpconfig (command-line utility).
Boot a DHCP JumpStart client: boot net:dhcp “ install .
Error messages are written to /var/adm/messages .
To run in.dhcpd in debug mode: in.dhcpd “d “v ( “v provides verbose output).
To run dhcpagent in debug mode: dhcpagent -d1 -f . -d can be 1 or 2, (2 produces more verbose output than 1), and “f forces the process to run in the foreground.
Host acquisition problems are normally related to dynamic DNS configuration, where either the DHCP server is not permitted to update the DNS server (no allow-update entry in /etc/named.conf ) or the DNSdmain symbol is not configured with the DNS server name on the DHCP server.
Stop and start DHCP server by running /etc/rc3.d/S34dhcp stop , then /etc/rc3.d/S34dhcp start . ( /etc/init.d/dhcp stop and /etc/init.d/dhcp start will work because the files are hard linked.)
Manually acquire a lease by running ifconfig < interface > dhcp .
Check the DHCP client status by entering ifconfig < interface > dhcp status .
