Choose Your Default Kernel Configuration :

IPCop uses the GRUB boot loader to give you a choice of kernel configurations. During boot, the GRUB splash screen will appear.

You will have 5 seconds to touch a keyboard key, before GRUB boots your default configuration. If you do not choose a configuration the default configuration, IPCop, will boot. If desired use the keyboard arrow keys to select a new kernel configuration.

If you want to use another configuration, make sure you can boot with it.

The Failsafe Configuration

The IPCop configuration is considered the Failsafe configuration. If you have a problem running another kernel configuration run the IPCop configuration.

GRUB’s configurations are configured to be “sticky.” In other words, GRUB will keep booting the last configuration chosen with the arrow keys, until the arrow keys are used to change its configuration.

There are four kernel configuration choices available:


This kernel configuration is suitable for single 
processor machines with motherboards that do not support 
the Advanced Configuration and Power Interface, ACPI, 
feature, see the ACPI discussion. This configuration 
is the most basic and should run on most processors 
and motherboards, even ones covered by the other 
kernel configurations.


This kernel configuration is suitable for 
motherboards that have more than one processor, 
Symetric Multiprocessing. Choose this configuration 
if your mother board has more than 1 processor. 
If your processor chip(s) support hyperthreading 
you should probably be running the ACPI HT kernel.

IPCop (ACPI enabled)

The Advanced Control and Power Interface, 
ACPI, allows IPCop to monitor key hardware 
metrics such as power and processor temperature. 
If necessary, IPCop, will power itself off to 
protect your processor and motherboard. ACPI 
requires an ACPI enabled chip set on your 
motherboard, ACPI aware BIOS, and the use 
of the “IPCop ( ACPI enabled )” kernel. 
If you don’t know if your motherboard is 
ACPI enabled, check your motherboard or 
computer’s documentation. If you can’t 
find out, try booting one of the ACPI 
enabled kernels and check to see if the 
apci driver came up properly by logging 
in as root and typing:
# dmesg|grep ^ACPI:

Verify the ACPI reported no errors. If an error is reported, reboot and select another kernel configuation.

IPCop SMP (ACPI HT enabled)

This kernel configuration supports processor 
chips with hyperthreading, HT, SMP and ACPI. 
Some Intel processors support hyperthreading, 
which is treated as an SMP, multiprocessing, 

Once you have chosen an appropriate kernel configuration, press the Enter key to boot IPCop.

Changing the Default Configuration

But I want IPCop to boot automatically!” The kernel configuration last chosen will be the default configuration, until changed.

Test Your Access to IPCop

Make sure you can access IPCop via a web browser. IPCop moves selected ports away from their standard numbers so that you can forward the well-known ports to real servers on your ORANGE network. The following examples assume you have set your GREEN network interface to If not substitute the correct IP address. Verify that you can ping IPCop from a GREEN network machine. On Windows enter:

C:\ ping

On *nix and Macintosh OS X enter:

$ ping -n

IPCop’s DNS proxy has not yet been enabled from its administration pages, so the ping command, above, deliberately stops ping from attempting to look up the fully qualified host name of the IPCop PC.

If ping works attempt to access your IPCop by opening a web browser to URL: []

You should try the HTTPS, secure http port, next by attempting to access URL: []
