Bind Mac with Ip address

shipon_97 · 01-24-2007, 10:17 AM

hI FRIENDS ,

I just want to know How I can bind my MAC address of lan card with my IP address without configuring DHCP server in Linux Distribution . Is there any third party tools or other way... ... Plz give me some directions .
I am using Redhat Enterprise 4 server .

My another question is , if I make RAID into my HDD , then using which command I will see the RAID / Mirror Drive ?

It sounds like you're talking about static IP rather than DHCP. If so you just configure the NIC to do static IP and input the address along with netmask etc...

HOW you do the above depends on what distro you're using.

Please let us know which distro (e.g. Suse, RedHat, Ubuntu, Fedora Core, Debian ...) and version of same you're using.

The easiest way I can think of is to simply set a static IP one the computer in question. I'm not sure which distro you're using but I'll tell you how to do this with Slackware (since that's what I'm most familiar with) and it shouldn't be wholly different for the distro you're using. Go into the directory in /etc for your init scripts (probably rc.d) and make sure dhcpd (or whatever your distro uses for a dhcp deamon) is not executable using chmod. This prevents your computer from pulling an IP from whatever DHCP server may be set up on your network. Then modify the rc.inet1.conf file (should also be in one of your init directories), to read something like this:

Code:

# Config information for eth0:
IPADDR[0]="<IP you want goes here>"
NETMASK[0]=""
USE_DHCP[0]="no"
DHCP_HOSTNAME[0]=""

That should do the trick.

You can run the RedHat network config command:

/usr/sbin/redhat-config-network.

OR

You can manually edit the file in /etc/sysconfig/network-scripts. File will be ifcfg-eth0 for eth0, ifcfg-eth1 for eth1 etc...

An example file from my RH AS 3 system:

Code:

DEVICE=eth0
BOOTPROTO=static
HWADDR=00:0A:30:A1:D7:45
ONBOOT=yes
TYPE=Ethernet
IPADDR=10.0.19.21
NETMASK=255.255.252.0
GATEWAY=10.0.19.1
SLAVE=no
ETHTOOL_OPTS="autoneg off speed 100 duplex full"

In the above:
The BOOTPROTO tells it to do either dhcp or static - you want static.
HWADDR should NOT be changed. This is the MAC address specific to your card.
ONBOOT=yes tells it start up at boot.
IPADDR is the static IP address.
NETMASK and GATEWAY should be whatever is appropriate to your network.

ETHTOOL_OPTS - Above turns off auto negotiation and hard sets the interface to speed 100 and full duplex. This is not required and may not work on some NICs. See ethtool man page for more detail. If it doesn't work then mii-tool likely does.

Don't forget to also update your /etc/hosts file with the IP.

P.S. The MAC, IPADDR and other things above were obfuscated so don't tell me the NETMASK isn't right.

Friends ,

This is the procedure how I can Bind IP with a MAC address of a LAN card of the server . Now I have 10 clients also 10 LAN cards through my Linux RHEL4 server . Now I want to bind ip address of the client pcs with their LAN MAC Address , so that they cannot use another different IP which I m not provided to them .

Plz help me How can i do that ?
