Free readable software for linux

SchemaCrawler project is a command-line tool to output your database schema and data in a readable form.
The output is designed to be diff-ed with previous versions of your database schema. SchemaCrawler is also an API that improves on the standard JDBC metadata.
Enhancements:
- SchemaCrawler now comes with bundled downloads for Microsoft SQL Server and MySQL.

keyspeedapplet project is a panel applet to show the speed you are typing.

This is an Applet, similar to the applets, showing the cpu-speed, which shows the speed you are currently typing.

It shows the average speed of the last 15 seconds and the average speed of the last minute.

In addition it shows how many errors you made and features a highscore list which is stored human readable in ~/.keyspeedrc.yaml

KFireWatcher is a application to view the firewall logs in a more readable form. (just remote ip address, local if local connection, only the needed infos...)

Needs kommander 3.5, and a separate firewall-log file (you can separate firewall lines with syslog-ng).

Accepts logs multilines with line format (standard iptables):

Dec 12 12:14:47 Machine Prefix:IN=eth0 OUT= MAC=00:13:8f:4f:59:fc:00:04:ed:00:01:91:08:00 SRC=220.253.135.60 DST=192.168.1.57 LEN=48 TOS=0x10 PREC=0x40 TTL=107 ID=2699 DF PROTO=TCP SPT=1187 DPT=6081 WINDOW=65535 RES=0x00 SYN URGP=0

Gear project draws a gear in an open office drawing.

You can then load the open office drawing and a nice looking gear is shown.

You can adapt the nr of tooth from the commandline, the shape of the tooth can be changed from the source.

How does it work?

I unzipped an open office drawing and looked how the lines in a file were made, then i automatically generated the lines into the content.xml file and zip the stuff again to make a valid document.

Isnt it great to have open formats (that are also well readable...)!!!

What is essential...

Well, in the archive that you got this program in, there is a odg directory this contains all the files that make up a valid OpenOffice drawing. The program should be run in a place where this odg directory is found...

example you unzipped this archive in a temp directory and now your file tree looks
like this : temp/gear/odg
then you should run the gear program from the temp/gear directory. .

well, it isnt that hard, you will figure it out...

Alphabet Soup project attempts to determine a number of things about the shapes of letters in several different writing systems.

First, it hypothesizes a set of basic building blocks that all letters are built up from.

Second, it hypothesizes a set of rules, a grammar or syntax, which defines how those pieces combine to make different letters.

It can generate individual letters, randomize letters in an input string to create weird but readable text, or generate random strings of symbols.

The PHP Firewall Generator is a simple PHP script that generates a firewall script for iptables or ipchains based firewalls. The script is created based on configuration rules entered by the user. The aim is to support a rule set similar to those supported by commercial Firewall systems, and make it easy to configure.

Make sure that you have apache and PHP installed (tested with apache-1.3.19-5 and php-4.0.4 from Red Hat 7.1 but shouldwork with others).

Make sure that PHP is actually running.
Make sure that you have iptables installed. Tested with iptables-1.2.1a-1 from Red Hat 7.1
Run this as root:
make install
If you dont have make installed on your system, then you could just run:
installme
Make sure that the files in /var/www/html/phpfwgen/ are readable by the HTTP daemon user (often httpd or apache) and that the files in /var/lib/phpfwgen are readable AND writeable by this user.
The script gets copied into /var/www/html/phpfwgen/ so you should be able to access it as http:// /phpfwgen/
Make sure that the files created in /var/lib/phpfwgen make sense, particularly the "interfaces" file.

nstreams is a program that analyzes the networks streams occuring on a network and prints them in a human readable form. This is useful when you want to set up a firewall but do not know your needs/the needs of your customers.
Nstreams can parse the tcpdump output, or the files generated with the -w option of tcpdump. It can also directly sniff the data that appears in the network.
Enhancements:
- Applied patch from Guillaume Morin which solved some sigsegv issues

Metalinks is an effort to promote the use of Peer to peer technology to aid web administrators in keeping their bandwidth down. metalink project defines a usable and simple way to share metadata in hash and digest forms using XML.
Data integrity is getting a larger problem on the net and trusted secure bandwidth is often limited. The solution is to use encryption to ensure the resulting data is correct, which enables you to pump the data through an unsecure connection with possible data corruption. Simple because it can be detected, the changes of going to work with the wrong file are very slim.
These metadata pointers can be used by modern P2P networks to identify and gather the right data, therefore the metadata XML record is a bit like a link. Hence the name metalinks.
The good thing about XML is that it is machine readable. Using XSLT we can also make this human readable. So, opening a metalinks record in your browser will result in a simple description of the file and P2P links you can click on.
After gathering the data, the integrity can be as securely checked as the amount of metadata that is available in the metalink XML record. This means that the reciever can check the SHA1, MD5, SHA512 and others provided in the record.
Enhancements:
- This release adds support for pieces, which is a list of hashes for parts of the file.
- The new hashlist option allows you to export all the hash information, which is good for integration and hash verification list generation.
