Devil-Linux is a special Linux distribution, which is used for Firewalls / Routers. The goal of Devil-Linux is to have a small, customizable and secure (what is secure in the internet ?) Linux. The future of Devil-Linux will go far beyond an ordinary Router, we will provide a lot of other services, but the Distribution will still be easy and fast to maintain.
Bootable ISO image is contained in bootcd.iso file.
The configuration file is /etc/sysconfig/config
| Parameter | Description | Values | Sample |
|---|---|---|---|
| UTC | Defines if the local clock is UTC (GMT) or to the local time | yes/no | yes |
| TIMEZONE | Defines the local time zone.
Available timezones can be found in the /usr/share/zoneinfo |
string value | US/Eastern |
| KEYBOARD_LAYOUT | Defines which keyboard layout should be loaded | string value | de-latin1 |
| INITRD_MODULES | Defines which modules should be loaded during boot time. This parameter is to support SCSI or BLOCK devices | string value | BusLogic |
The configuration file is /etc/sysconfig/config
| Parameter | Description | Values | Sample |
|---|---|---|---|
| HOSTNAME | hostname | string value | devil |
| DEFAULTGATEWAY | IP address of the default gateway | IP address in dotted notation | 10.90.1.1 |
| DEFAULTGATEWAY_IF | Interface on which we reach the default gateway | string value | eth0 |
| START_ROUTING | Should routing be enabled for the first time ? | yes/no | yes |
| START_FIREWALL | Should the script /etc/init.d/firewall.rules be executed at boot time ? | yes/no | yes |
| DISABLE_ECN | Disable ECN (early congestion notification) ? This is needed if you have problems connecting to some websites. | yes/no | yes |
The configuration files are located in /etc/sysconfig/nic directory.
You need one file for each interface. The filename has to begin with ``ifcfg-``.
| Parameter | Description | Values | Sample |
|---|---|---|---|
| ONBOOT | Should the interface started at boot time ? | yes/no | yes |
| DEVICE | Device name of the interface (eth0, eth0:0, eth1 ...) | string value | eth0 |
| DHCP | Should the IP address be requested from a DHCP server ?
Or should even a DHCP server run on this interface ? NOTE: for a DHCP server you need to assign a static IP address |
yes/no/server | no |
| IP | IP address of the defined interface. Leave empty to bring interface up without an IP address. | IP address in dotted notation / empty | 10.90.1.2 |
| NETMASK | Network mask for this interface | IP address in dotted notation | 255.255.255.0 |
| BROADCAST | broadcast address for this interface
leave this setting empty for an automatic assignment |
IP address in dotted notation | 10.90.1.255 |
| MAC | Changes the MAC address of the interface | MAC address with colons | 12:34:56:67:91:11 |
| MODULE | Name of the module to load for this interface.
Leave this setting empty when module is already loaded or this interface is an IP alias. |
string value | pcnet32 |
The configuration file is /etc/sysconfig/software.
Take a look inside this file to see which packages are available.
No package is installed by default.
Before a particular software or service is activated, the corresponding software must be installed (see Software installation above).
Edit the /etc/sysconfig/config file and set START_<service> to yes or no depending on what you need.
No service is launched by default except routing and firewall (see Network setup above).
Devil-Linux is based on SysV init system.
The default runlevel is 3 (multiuser with network). Currently, it is not supported to boot into another runlevel, but you can switch runlevel with the init command.
Symbolics links are made in /etc/init.d/rc3.d directory to the /etc/init.d/ scripts.
Activation order is determined whith the link's name.
Example in /etc/init.d/rc3.d :
The best and safest way when upgrading is to start with the new etc.tar.gz file. Next, you can recover previous configurations files with caution : don't forget to check changes log to see which services could be affected with the new release.
Files you may want to recover :

In the explanation below, we use hdc as the harddrive, replace this with the devicename your harddisk is using.
Create one partition on the harddisk you want to use using the command fdisk.
The result ("fdisk -l") should look like this:
Disk /dev/hdc: 16 heads, 63 sectors, 8126 cylinders
Units = cylinders of 1008 * 512 bytes
Device Boot Start End Blocks Id System
/dev/hdc1 1 8126 4095472+ 8e Linux LVM
Create a physical volume (PV) from the partiton created in step above.
pvcreate /dev/hdc1
Create a volume group (VG) named "devil-linux" using the PV /dev/hdc1
vgcreate -s 8M devil-linux /dev/hdc1
(increase the PhysicalExtentSize of 8M to make use of more than 512GB)
Now we are going to create the "partitions" (=logical volumes).
Each of the Logical Volumes is optional, so just create the ones you need.
Also adjust the size of the LVs to fit your needs.
Create the LV using the following commands:
lvcreate -C y -L 256M -n swap devil-linux
mkswap /dev/devil-linux/swap
Create the LV using the following commands:
lvcreate -L 512M -n log devil-linux
mkreiserfs /dev/devil-linux/log
Create the LV using the following commands:
lvcreate -L 512M -n spool devil-linux
mkreiserfs /dev/devil-linux/spool
Create the LV using the following commands:
lvcreate -L 512M -n squid devil-linux
mkreiserfs /dev/devil-linux/squid
Create the LV using the following commands:
lvcreate -L 4G -n data devil-linux
mkreiserfs /dev/devil-linux/data
Save your configuration (so you have a least one lvmbackupfile)
save-config
Now reboot to test if all logical volumes get mounted correctly.
Because the software used in Devil-Linux is a complilation of many software packages written by different people all over the world the documentation for the software is maintained and updated by the group who wrote the software.
But here we have collected short installation- and configuration descriptions for some of them.
We're more than happy to add your configuration hints to our documentation.

First of all you must register on their website http://www.dyndns.org
Then you type:
ddup -makeconf
This will start a guide which is going to ask you for your user name and password (on dyndns.org) and lastly which user who can use ddup, write root.
Don't forget to run the save-config script!
