Free fully 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!

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.

Libunicode offers low-level Unicode (UTF-16) text processing functionality,
which can be divided into three categories:

- Character handling
- String handling
- Charsets handling

Libunicode uses ISO/IEC 10646-defined UTF-16 encoding for storing and minipulating all character entities. It will supports other encoding standards (e.g., UTF-8, ISO 8859-x, etc.) for input and output only.

Libunicode bases, where applicable, on "Single Unix Specification, Version 2(R)" (susv2) as API and semantics reference. susv2 is the unification and superset of de jure POSIX and ANSI C (run-time library part) and de facto BSD standards. This means that, if you know standard character and string handling functions, you can readily use libunicode; and, if you have apllication using standard character/string processing facilities, you may with minimal troubles make it Unicode-aware.

Also, dont let word "Unix" in standard name confuse you. Susv2, as same as POSIX, is standard for *Open* operating systems, where MS Windows, MacOs, etc. fit. Such name was choosen by OpenGroup, maintainer of susv2, to unite and defend market sectors actively attacked by Microsoft with its "decommodizing" tactics. Libunicode is bright example of opposite approach, offering crossplatform portability and comptability for Unix and Win32 systems. (*)

(*) Opinions presented in the paragraph above are solely opinion of documentation author and should not be considered as reflecting real state of the things.

Libunicode defines new type, Uchar, which can handle any non-surrogate UTF-16 character without space overhead.

Library offer two APIs, one being precise remapping of susv2 functions, and one offering slightly higher-level API, with automatic memory management fully controlled by user.

Functions of 1st API (fully standard-compliant, the one you probably will use) uses u_ prefix, e.g. standard

char *strchr(const char *s, char c);

becomes

Uchar *u_strchr(const Uchar *s, Uchar c);

Functions of 2nd API use uni_ prefix. They are conceived to be used in special environments, for example, in Apache webserver modules. Most functions has completely identical u_ and uni_ implementation, but following have differring from standard argument structure and semantics:

uni_strcat
uni_strncat
uni_strdup
uni_strndup
uni_strcpy
uni_strncpy

You should consult library reference for their full description.
