You aren't "joining" the domain with a linux machine.
You can specify to the machine what domain you wish it to belong to, and create an entry in that domains DNS server - and you have effectively "joined" the domain.
If you are referring to joining an AD domain - that is a different story.
At any rate, to setup your IP:
First - you need an IP. If you are using DHCP now, DO NOT use the one you are currently assigned. In some environments, this is ok - but I can't say for sure - so to play it safe don't do it. You can screw up the DHCP pool - have dup addy's - it'll be a mess.
Once you have your IP - look in /etc/sysconfig/network-scripts/ for a file that is labeled:
ifcfg-eth0
replace "eth0" with your interface name (eth1, ra0, whatever)
If you don't have one, create one. It MUST have that naming convention.
Once you have one - and it may already be there - open it and make sure at least the following are present:
Code:
DEVICE=eth0(replace with your IF name)
HWADDR=your mac address (00:00:00:00:00:00) <- in that format
BOOTPROTO=static
ONBOOT=yes
TYPE=Ethernet
IPADDR=your IP
NETMASK=your subnet mask
***NOTE - the onboot entry above MUST be all caps. It won't let me do it, though - because this forum thinks it's VB code
Now, there is another file in /etc/sysconfig/ called network.
In here - specify the following:
Code:
NETWORKING=yes
HOSTNAME=your FQDN
Then at a command prompt:
Code:
service network restart
This should bring up your interface with all of the configurations you just provided it. It will come up this way everytime you reboot - so if the machine goes down - you won't have to reconfigure.
