DESCRIPTION ^
The Jabber::Connection package provides basic functions for connecting clients and components to a Jabber server.

conn-close gives us possibility to get rid of entries in ip_conntrack about ESTABLISHED TCP connections that goes through our server.

conn-close script uses hping2 to send spoofed RST packets which will fool conntrack and cause specified connections to be considered by conntrack as closed (now these connections will be in ip_conntrack in CLOSE state), even though RST packets will be more likely discarded by destination host.

Information about connections is read of course from /proc/net/ip_conntrack.

Idea was taken from script seen somewhere on the internet.

Bauk HTTP server project is a high-performance Web server. Bauks advanced architecture and unique design provide high performance and many original features, ie. ability to serve unlimited number of Virtual Hosts/simultaneous HTTP connections per single server process without performance loss.
Full installation requires only a single directory of UNIX file system used as a working directory for Bauk executable. Configuration process is simple and performed by adjustment of Bauk configuration script.
Main features:
- Full HTTP/1.1 and CGI/1.1 standard compliance
- HTTP authentication, Basic method, auth script per Virtual Host
- Unlimited number of Virtual Hosts without performance loss
- Virtual Host aliases
- Unlimited number of simultaneous HTTP connections per single Bauk process with no performance loss (Special Edition)
- Persistent (Keep-Alive) connections
- URL Path; define URL and path with type of access; ie. read, write, browse, execute, require HTTP authentication, etc.
- OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE methods of HTTP request defined by HTTP/1.1, configurable per URL Path
- Content negotiation by client language and charset
- Configurable MIME types
- Configurable HTTP headers by MIME type
- Configurable HTML error documents / CGI executables
- Directory browsing; view content of directories with HTML links
- Execution of CGI programs/scripts
- SUID/SGID for CGI execution
- Chroot for CGI execution; chroot CGI to Virtual Hosts home
- 3 security layers for CGI execution: by URL limit to X-only ie. CGI dir; for RX-URL imply X-only for X-able files; impose X-only by file extension ie. CGI executables wrongly placed and no X flag
- Quotas for CGI execution; number of simultaneous CGI processes, execution priority, max execution time (duration), max CPU time, memory, filesize
- Quotas of network traffic in/out per Virtual Host (I/O speed limit)
- Quotas of connections per Virtual Host
- Quotas of connections per client IP number
- Access restriction by IP address; forbid and allow-only
- Access restriction by valid HTTP referrer
- Configurable HTTP-log format and location for Virtual Hosts
- Configurable singleprocess or multiprocess architecture
- Chroot for Bauk server process
- Full configurability; virtually all Bauk features are configurable by simple configuration script adjustment
- Easy configuration by script language; built-in configuration script interpreter with preprocessor, file-inclusion, block and single-line comments, two data types, variables, arithmetic operations and built-in functions
- Easy administration
- Flexibility

PPTP stands for Point to Point Tunneling Protocol. It was developed by a consortium including Microsoft and is used for establishing VPN (Virtual Private Network) tunnels across the Internet. This allows remote users to securely and inexpensively access their corporate network from anywhere on the Internet.
PPTP is built on a client-server model for establishing VPN connections. Most Microsoft operating systems ship with a PPTP client, so there is no need to purchase third-party client software. PPTP has the additional advantage over other VPN technologies of being easy to setup.
Before Poptop, no solution existed if you wish to connect PPTP clients to Linux servers. Using Poptop, Linux servers can now function seamlessly in a PPTP VPN environment. This enables administrators to leverage the considerable benefits of both Microsoft and Linux operating systems.
The current release version supports Windows 95/98/Me/NT/2000/XP PPTP clients and Linux PPTP clients.
Poptop is free software, licensed under the terms of the GNU GPL.
Main features:
- Microsoft compatible authentication and encryption (MSCHAPv2, MPPE 40 - 128 bit RC4 encryption)
- Support for multiple client connections
- Seamless integration into a Microsoft network environment (LDAP, SAMBA) using RADIUS plugin
- Works with Windows 95/98/Me/NT/2000/XP PPTP clients
- Works with Linux PPTP client
- Poptop is, and will remain, totally free under the GNU General Public License

MuSE is a user-friendly tool for network audio streaming.
MuSE provides the free software community with a user friendly but powerful tool for network audio streaming, making life easier for indypendent free speech online radios.
MuSE is an application for the mixing, encoding, and network streaming of sound: it can mix up to 6 encoded audio bitstreams (from files or network, mp3 or ogg) plus a souncard input signal, the resulting stream can be played locally on the sound card and/or encoded at different bitrates, recorded to harddisk and/or streamed to the net.
When sent to a server, the resulting audio can be listened thru the net by a vast number of players available on different operating systems.
To be operated MuSE offers graphical interfaces and a documented commandline interface in the good old unix style.
Main features:
- Mixes up to 6 channels + 1 soundcard input channel simultaniously
- decodes and mixes both ogg and mp3, from files or network streams
- encodes at different bitrates and sends multiple mp3 or ogg streams to icecast, shoutcast and darwin servers.
- offers two different intuitive user interfaces and a documented command line interface
- play, stop, pause/resume, position and volume for each channel, looping thru playlists and reconnecting automatically to lost server connections
- efficient multithreaded architecture with emphasys on performance to support older CPUs
- reusable API interface to the core mixing engine permits to adapt new interfaces
