I know command service network stop will stop networking. What i want is to disbale just interface eth1 or eth2

Is there any command that can disable network interface

regards,

JO

To stop / disable network interface use ifconfig command. It is used to configure the kernel-resident network interfaces.

You can pass up and down flags/option to this command.
==> up - This flag causes the interface to be activated. It is implicitly specified if an address is assigned to the interface.
==> down - This flag causes the driver for this interface to be shut down.

So the following command will disable eth1:
And to get it back type the command:

Jo,

you can use ifup or ifdown command:
* ifup : bring a network interface up
* ifdown : take a network interface down

To take down eth1
To take up eth1:

I have tested both, "ifconfig <int> down" and "ifdown <int>" and the difference I perceived was that the first one had an impact in the routing table, since all the static routes associated with the interface disappeared, even after restarting the interface with the command "ifconfig <int> up". I am not sure it is the normal result of the command or if it is particular to the OS I was using to test (CheckPoint SecurePlatform).
