Free highly sensitive person software for linux

JWhoisServer project is a small, fast, and highly configurable RFC 3912 compliant whois server written in Java and using RDBMS as a storage engine.

Engauge Digitizer project is digitizing software that converts an image showing a graph or map into numbers. The image file can come from a scanner, digital camera, or screenshot. The numbers can be read on the screen, and written or copied to a spreadsheet.

Highlights for beginners include an intuitive interface and extensive context-sensitive documentation. Highlights for experts include compensation for image distortion, cartesian and polar coordinates, linear and logarithmic coordinates, automatic scanning, graphical previews, and browser help.

glAnts project is a open source mech game.
glAnts is a combination game and simulation loosely based on Battlezone or SpectreVR.
It supports third and first person views. Drive your mech and kill the bots. Windows and Linux versions are available.
Enhancements:
- Added networking, but it doesnt work totally.
- Some interface changes.

Enter aims at beign lightweight, yet highly configurable login manager for X. Supporting many different desktop setups. It is written in C with minimal dependencies, making it an excellent choice when using other lightweight window managers, such as fluxbox.

The Linux Virtual Server is a highly scalable and highly available server built on a cluster of real servers, with the load balancer running on the Linux operating system.

The architecture of the server cluster is fully transparent to end users, and the users interact as if it were a single high-performance virtual server.

The basic goal of the Linux Virtual Server Project is to:
- Build a high-performance and highly available server for Linux using clustering technology, which provides good scalability, reliability and serviceability.

IPChains is a Perl module to create and manipulate ipchains via Perl.

SYNOPSIS

use IPChains;
$fw = IPChains->new(-option => value, ... ); $fw->append(chain);

This module acts as an interface to the ipchains(8) userspace utility by Paul "Rusty" Russell (http://www.rustcorp.com/linux/ipchains/). It attempts to include all the functionality of the original code with a simplified user interface via Perl. In addition, plans for log parsing facilities, an integrated interface to ipmasqadm, and possibly traffic shaping are slated for up and coming versions.
The new() and attribute() methods support the following options:

Source

Specifies origination address of packet. Appending hostmask to this address using a / is OK, as well as specifying it separately (see SourceMask).

SourceMask

Hostmask for origination address. Can either be in 24 or 255.255.255.0 style.

SourcePort

Specific port or port range (use xxx:xxx to denote range), requires specific protocol specification.

Dest

Specifies destination address of packet. Appending hostmask to this address using a / is OK, as well as specifying it separately (see DestMask)

DestMask

Destination address, (see SourceMask).

DestPort

Destination Port, (see SourcePort).

Prot

Protocol. Can be tcp, udp, icmp, or all. Required for specifying specific port(s).

ICMP

ICMP Name/Code (in place of port when ICMP is specified as protocol).

Here is a small table of some of the most common ICMP packets:

Number Name Required by

0 echo-reply ping
3 destination-unreachable Any TCP/UDP traffic.
5 redirect routing if not running
routing daemon
8 echo-request ping
11 time-exceeded traceroute

Rule

Target. Can be ACCEPT, DENY, REJECT, MASQ, REDIRECT, RETURN, or a user-defined chain. Note: This is case sensitive.

Interface

Specify a specify interface as part of the criteria (ie, eth0, ppp0, etc.).

Fragment

Rule only refers to second and further fragments of fragmented packets (1 or 0).

Bidir

Makes criteria effective in both directions (1 or 0).

Verbose

Set verbose option for setting rules or list() (1 or 0).

Numeric

Show output from list() in numeric format. No DNS lookups, etc.. (1 or 0).

Log

Enable kernel logging (via syslog, kern.info) of matched packets (1 or 0).

Output

Copy matching packets to the userspace device (advanced).

Mark

Mark matching packets with specified number (advanced).

TOS

Used for modifying the TOS field in the IP header. Takes 2 args, AND and XOR masks, (ie, (TOS => ["0x01", "0x10"])). This feature is highly untested.
The first mask is ANDed with the packets current TOS, and the second mask is XORed with it. Use the following table for reference:

TOS Name Value Typical Uses

Minimum Delay 0x01 0x10 ftp, telnet
Maximum Throughput 0x01 0x08 ftp-data
Maximum Reliability 0x01 0x04 snmp
Minimum Cost 0x01 0x02 nntp

Exact

Display exact numbers in byte counters instead of numbers rounded in Ks, Ms, or Gs (1 or 0).

SYN

Only match TCP packets with the SYN bit set and the ACK and FIN bits cleared (1 or 0).

Relations is a Perl module with functions to use with databases and queries.

SYNOPSIS

use Relations;

$as_clause = as_clause({full_name => "concat(f_name, ,l_name)",
{status => "if(married,Married,Single)"})

$query = "select $as_clause from person";

$avoid = to_hash("virustbug","t");

if ($avoid->{bug}) {

print "Avoiding the bug...";

}

unless ($avoid->{code}) {

print "Not avoiding the code...";

}
