For linux DHCP client, the DHCP client is named dhclient
  Its config file by default is /etc/dhclient.conf. If you want a file  other than default then you can specify as argument to dhclient binary  when you start it.
  Inside the config file add the following entry to send the client-name to server
  send host-name "yourhostname";

/etc/sysconfig/network-scripts/ifcfg-eth? with the statement
DHCP_HOSTNAME=hostname. A quick google should show you the correct format
foryour distro.

tosend its host name to dhcpserver so that it gets updated in ddns. Till now
i was using the host declaration like host test { hardware wthernet 00:11..
ddns-hostname "testmachine"; } but i dont want this declaration i want to
update the original host name of the client in ddns. It is not getting
updated. Which client ? WIndows and Mac OS both send their configured
machinename, as do a oh bydefult windows and Mac will send their host name.
good. but i use linx as client.. few others. For the ISC client, I believe
you'll need to set this in the client config file. where is that file
located. which option should i change? thanks, -"kalyan"
