Free automatic software for linux

Automatic Firewall is a script that will automatically configure a firewall. If you are a broadband or dial-up user who doesnt have a firewall script, you need to get one to protect yourself. AutoFW is made to help you do that with no efforts.
Many people when connecting to the internet need a firewall script made for them so they can surf the net without being susceptible to various attacks. Most, if not all (until now :-), of the existing scripts are written for a large range of requirements and require some tweaking to make them work for a specific user. However many users do not know which parameters to fill in the script config file.
AutoFW intends to provide a simple firewall script that you just need to fire and forget. You make sure to run it on computer start-up or just before connecting to the net, and it will detect network condition and setup appropriate firewall rules for you.
In order to be "smart" AutoFW has to be limited, the current scope of AutoFW are standard broadband connections, it will also cover dial-up users and stand-alone servers.
AutoFW works only for Linux IPTables firewall and needs the iptables utility to update the firewall, it also needs the ifconfig utility, both of these are available on any standard install of a GNU/Linux machine.
AutoFW also needs the ip program which is part of the iproute2 package, sometimes also called iproute. It is available as a package for any standard GNU/Linux install, not it might not be installed in your particular.
There are two parts that do automatic detection, one is for interfaces and IPs and the other is for open listening ports.
The interface part looks at all the active interfaces in the machine and classifies them between internal and external. It does that by looking at the IPv4 address of the device. If it is one of:
127.0.0.0/8
10.0.0.0/8
172.16.0.0/12
192.168.0.0/16
it is considered to be an internal IP and thus an internal interface, otherwise it is an external IP and thus an external interface. There is no handling of an interface with both an internal and an external IP on it.
The listening ports are scanned for a known port and the accompanying known program name that binds to that port, known ports are opened later in the configuration stage.
The configuration itself is very simple for now, without many of the bell and whistles that exist in other scripts, but it works for the basic needs and provides adequate protection.
Enhancements:
- Internal systems are now protected, as well as servers and NAT gateways.

Auto Contrast is a script-fu based on a technique by lylejk of dpreview.com that performs an entirely automatic contrast adjustment.

You may like the effect, dislike it, or not see a change, but its worth a try!

Contrast Autostretch is a simple plug-in does an automatic contrast stretch. For each channel in the image, it finds the minimum and maximum values, and uses that information to stretch the individual channels histograms to the full contrast range.

For some images it may do just what you want; for others it may be total crap. If the latter, you may want to consider using the Normalize plug-in by Adam Moss.

FAI-CD represents fully automatic installation from CD or DVD.
FAI-CD puts all data needed for a fully automatic installation on a CD. So not network is needed and you can install the whole system from CD. The script creates an ISO image that includes the nfsroot, the configuration space and a partitial Debian mirror.
- Choose FAISERVER for installing the host as a FAI install server
- The XFREE configuration uses 24 bit color depth by default, so on older graphics cards, if will not succesfully start gdm.
- The system will be installed to the first disk (either IDE or SCSI). All data on the disk will be deleted.
- All log files from the installation can be found in /var/log/fai/localhost/last/
- After the installation the account demo with the password fai is available.
- The root password is also fai.

The eHomeConfigurator is a tool for the automatic configuration of eHome systems.
The goal of this tool is to reduce the amount of human interaction neccessary to assemble and configure the components for an eHome.
The tool provides a graphical interface to enter the structure of your home, and select pre-defined services you want to run in this eHome. After this two easy steps it automatically shows which devices are needed in each room to fulfill this services and automatically configures the eHome gateway to run this services in way tailored to your home.
The eHome gateway software is built upon an OSGi framework (you can use a freely available OSGi Framework like Knopflerfish).
Enhancements:
- Extensive eHome model changes, a new service design, automatic service configuration and composition over functionalities, wizards for automatic configuration, an additional set of working eHome services (OSGi), and examples corresponding to the Ubicomp 2005 demo.

Midirecord is a simple command-line application to record a MIDI file with your MIDI keyboard.

Midirecord project also features automatic recording to a MIDI file when you play electric piano, and thus it may be used as a "recording daemon".
