Centos 6.2 set static IP


Hi folks,
I am continuing with the learning in my Linux Lab. So far I have done the following:
- Installed Centos 6.2
- Configured Samba both via command line and Swat (that was tricky)
- Built a Raid 5 array + Lvm
- Set up shared directories
- Installed a dlna server (tvmobili) all tvs see the Linux server
Next step is to allow the Macs in the house to gain acces to the linux. Anyone knows how to do that...?
I wanted to ask you which of these files is the one to set a static ip(os centos 6.2):

-rw-r--r--. 1 root root 254 Oct 7 17:01 ifcfg-lo

none of those files are relevant. Settings for your first ethernet nic would be in /etc/sysconfig/network-scripts/ifcfg-eth0 you can use the system-config-network tool to manage it. If you have Network Manager running, I would suggest you disable it, as it will cause conflist between the conventional way to manage server addresses.

no such file....

Thanks Chris, but I have no such file in that particular directory. The system-config-network tool gave no choices of configuration; it was empty so to speak.
Perhaps in centos 6.2 they placed that info somewhere else.

do you have a network connection in the first place? It seems very odd to be doing this AFTER configuring SaMBa...? what does "ifconfig -a" say? No eth0 listed there says there's no valid driver or no hardware found.

Hi,I use the same system,but I found the file /etc/sysconfig/network-scripts/ifcfg-eth0.I think you can use the command:'ifconfig -a',and check the output ,I think you just have not install the driver of your NIC correctly.

more....

Hi, the network is working fine and the drivers are installed. I configured samba with the 104 ip given by the dhcp but now i want to set it static. In the /etc/sysconfig/network-scripts/ directory there is a file called ifcfg-lo. See the contents below, but I think this one refers to the localhost.

DEVICE=lo
IPADDR=127.0.0.1
NETMASK=255.0.0.0
NETWORK=127.0.0.0
# If you're having problems with gated making 127.0.0.0/8 a martian,
# you can change this to something else (255.255.255.255, for example)
BROADCAST=127.255.255.255
ONBOOT=yes
NAME=loopback

This is the contents of ifconfig -a:

eth0 Link encap:Ethernet HWaddr 00:24:BE:BC:1D:1A
inet addr:192.168.100.104 Bcast:192.168.100.255 Mask:255.255.255.0

I see.I think you can build a file named ifcfg-eth0 in that directory.And add the following statement:
Code:
      DEVICE=eth0
      IPADDR='youraddr'
      NETMASK='yournetmask'
      NETWORK='yournetwork'
      ONBOOT=yes
Save it.Then,use the command
Code:
# service network restart
,and see the output.I think that will enable the eth0.You can also reboot your computer to check whether it is working correctly.
