How To Add A Host Name Identifier To A DHCP Server
Some times it is desirable to add a host name identifier at the DHCP Client to be recognized by the DHCP Server. This will allow for local host names to be resolved by their respective name on the local LAN. This works well with a DD-WRT enabled LinkSys router.
To do this, add the following line to your network configuration file (we will use file: "/etc/sysconfig/network-scripts/ifcfg-eth0" for this example): DHCP_HOSTNAME=<your desired host name for this NST DHCP client>
DEVICE=eth0 BOOTPROTO=dhcp ONBOOT=yes DHCP_HOSTNAME=probe-biostar
Configuring A Static IP Address
If the network your interface is connected to does not have a DHCP server, you will need to configure your system to use a static IP address. The following shows the contents of: "/etc/sysconfig/network-scripts/ifcfg-eth0" which is used to assign a static IP address of 192.168.12.100 to eth0 (an Ethernet interface):
DEVICE=eth0 BOOTPROTO=static IPADDR=192.168.12.100 NETMASK=255.255.255.0 NETWORK=192.168.12.0 BROADCAST=192.168.12.255 GATEWAY=192.168.12.1 ONBOOT=yes
NOTE: The above assumes that the gateway machine for the network has an IP address of: "192.168.12.1".
After editing this configuration file, you should restart the network service as shown below:
[root@tmobile network-scripts]# service network restart Shutting down interface eth0: [ OK ] Shutting down loopback interface: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: [ OK ]
