Can not find interfaces file on centos 5.5

Hi,

I am following the tutorial at http://cloudservers.rackspacecloud.com/index.php/Basic_Cloud_Server_Security

and am trying to set up the iptables

#Now we need to ensure that the iptables rules are applied when we reboot the server. At the moment, the changes will be lost and it will go back to allowing everything from everywhere.

#Open the file /etc/network/interfaces:

nano /etc/network/interfaces

#Add a single line (shown below) just after 'iface lo inet loopback':

...
auto lo
iface lo inet loopback
pre-up iptables-restore < /etc/iptables.up.rules

# The primary network interface
...

Open in new window


However, I can't find the interfaces file?

I've done a locate and it doesn't seem to be there. Is there another file I can put this line of code?

Thanks,

Julian

Under /etc/sysconfig/network-scripts/ you'll find a file for each interface ifcfg-*
This is the equivalent for CentOS, although I am not sure of the syntax you should use inside those files, to achieve what you are trying to.

Hi

They look like generic notes, may be related to something else and it says at the top of the file you need to refer to your OS notes.

There are many tutorials on the net;
http://www.frozentux.net/iptables-tutorial/iptables-tutorial.html
http://www.linuxreport.org/content/view/26/23/

If you want you can use the RH default rules by running system-config-securitylevel from the GUI.

You can use one of the following commands to find your interfaces files:

If you have locate on your system do the following

locate eth
locate ifcfg

if you don't get any output, do this
updatedb

and then run the above commands.

If however your system doesn't have this command try the following
find /etc -name *eth*

Hope it helps

On CentOS5.5 interface files are in the following directory:
/etc/sysconfig/network-scripts

The files are named ifcfg-eth0, ifcfg-eth1, etc.
