Icon execute feedback replaces the zooming rectangle that is drawn if you activate an icon in konqueror for execution feedback. It removes the rectangle and instead zooms the icon bigger and fades it out while doing. Its like MacOS X execution feedback.
Currently works in Konqueror, Kicker and all file dialogs. You will need a machine > 600 MHz for this though, else the
animation may be slow.
This is a patch against kdebase-3.5.6 and kdelibs-3.5.6
So you have to recompile the two packages. Please only do
that if you are experienced enough with recompiling KDE.
Apply the patches as follows:
1. Get kdebase-3.5.6
2. Get kdelibs-3.5.6
3. Get this patch
4. Unpack all archives
5. Change to the dir you unpacked kdelibs
6. Execute "patch -p1 7. Recompile kdelibs
8. Install kdelibs (necessary as some header files changed)
9. Change to the dir you unpacked kdebase
7. Execute "patch -p1 8. Recompile kdebase
9. Install kdebase
10. Logout of kde and then login again.
11. Watch the icons zooming
Have fun. If you dont understand the step by step manual above please inform yourself about how to recompile KDE on kde.org
Enhancements:
- Slowed down the animation a bit

PgWorksheet is a simple GUI frontend to PostgreSQL for executing SQL queries and psql commands without using the psql command line tool.

PgWorksheet allow you to execute SQL queries and psql commands against a PostgreSQL database with a GUI. The UI have been designed to be extremly simple and easy to use.

XPertMailer is a PHP class to send encoded MIME-type email messages like text, HTML, HTML embedded images, attachments, etc., to client, localhost, or relay SMTP servers with optional authorisation.
The class functions are optimised to execute in a very small time and to be easy to use. This reduces the size of the code and the time required to write it.
Data sending is done according to RFC 821 and RFC 2821, and the message type is in compliance with RFC 2045, RFC 2046, RFC 2047, RFC 2048, RFC 2049, and RFC 2822.
Enhancements:
- Added the clear attachments functionality

Ermixer is a very sophisticated OSS mixer with a lot of usefull features.
The simplest way to compile this package is usual:
1. `cd to the directory containing the packages source code and type `./configure to configure the package for your system. If youre using `csh on an old version of System V, you might need to type `sh ./configure instead to prevent `csh from trying to execute `configure itself.
Running `configure takes a while. While running, it prints some messages telling which features it is checking for.
2. Type `make to compile the package.
3. Type `make install to install the programs and any data files and documentation.
4. You can remove the program binaries and object files from the source code directory by typing `make clean.
Main features:
- handling of multiple profiles files;
- Real Time support;
- complete interface to the mixer capatibilities;
- a nices qt gui and curses interface;
- command line interface.
Enhancements:
- Now ermixer have a very nice qt gui which improve ease of usage.

Bandwidth Check is a small utility that helps an administrator measure the available bandwidth. In order to make use of this utility, you will need to turn on the chargen service, which is provided in many inetd implementations.

In order to make use of this utility, you will need to turn on chargen protocol.

To enable chargen on Linux:

create the following file /etc/xinetd.d/charge
service chargen
{
type = INTERNAL
id = chargen-stream
socket_type = stream
protocol = tcp
user = root
wait = no
disable = no
}
service xinetd restart

To Compile bwcheck

gcc -o bwcheck bwcheck.c

To execute

./bwcheck

./bwcheck 172.16.11.2
Throughput: 73390.74 kb

Trapdoor2 (td2) is an application that allows remote users to execute local commands by sending magic cookies. This can e.g. be used to alter local firewalling rules so people can connect to local services after sending the magick cookie.

td2 is implemented as high-secure https server. the daemon processes are running in a chroot jail with multiple rlimits set. even if td2 can be exploited (e.g. using a hypothetical security hole in the SSL implementation), it is very unlikely that the attacker can execute any commands on the machine and/or can cause any damage.

however - there never is a 100% guarantee that a system is secure. we believe that trapdoor2 can be used to make systems more secure, but if you use it in a bad manner, you do so on your own risk.

The policy is generated interactively. Operations not covered by the policy raise an alarm, allowing an user to refine the currently configured policy.
For complicated applications, it is difficult to know the correct policy before running them. Initially, Systrace notifies the user about all system calls that an application tries to execute. The user configures a policy for the specific system call that caused the warning. After a few minutes, a policy is generated that allows the application to run without any warnings. However, events that are not covered still generate a warning. Normally, that is an indication of a security problem. Systrace improves cyber security by providing intrusion prevention.
Alternatively, policies can be learned automatically. In many instances, the automatically learned policies can be used for sandboxing immediately. Sometimes, minimal manual post-processing is necessary.
With Systrace, untrusted binary applications can be sandboxed. Their access to the system can be restricted almost arbitrarily. Sandboxing applications that are available only as binaries is only sensible, as it is not possible to directly analyze what they are designed to do. However, constraining the system calls that large open-source applications are allowed to execute is useful too, as it is very difficult to determine their correctness.
System call arguments can be rewritten dynamically. This effects a virtual chroot for the sandboxed application. It also prevents race conditions in the argument evaluation.
Main features:
- Confines untrusted binary applications.
- Interactive Policy Generation with Graphical User Interface.
- Supports different emulations:
- GNU/Linux, BSDI, etc..
- System Call Argument Rewriting.
- Non-interactive Policy Enforcement.
- Remote Monitoring and Intrusion Detection.
- Privilege Elevation: Add-on capabilities.
