Free v3 software for linux

Myrinix - Digital Home Edition is meant to be a smart and centralized OS that can be implemented in a home environment.
Myrinix Digital Home Edition can be connected to a TV or other large screen to record and play DVD movies and surf the Internet. It also implements video sharing with the NX technology, and includes the videolan program for broadcasting video or music throughout the network.
Diskless client computers can connect with the server as it performs other tasks. Myrinix - Digital Home Edition is a bootable CD derived from Kanotix.
Enhancements:
- This release fixed a DBUS hang at startup on some computers and detection of USB drives as home at startup.
- An easy USB portable drive installer was added along with a locale changer for quick and easy language changes.

python-dvb3 is Python bindings for the Linux DVB v3 API.

&MP3FS is A read-only FUSE filesystem which transcodes audio formats (currently FLAC) to MP3 on the fly when opened and read. This was written to enable me to use my FLAC collection with software and/or hardware which only understands MP3. e.g. gmediaserver to a netgear MP101 mp3 player.
MP3FS is also a novel alternative to traditional mp3 encoder applications. Just use your favorite file browser to select the files you want encoded and copy them somewhere!
How it Works:
When a file is opened, the decoder and encoder are initialised and the file metadata is read. At this time the final filesize can be determined as we only support constant bitrate mp3s.
ID3v2 tags are created from the vorbis comments in the flac file. They are located at the start of the file. As such, an application scanning a directory to read tags should not cause too much of a performance hit as the actual encoder does not need to be invoked (depending on how much data the read asks for).
A special exception to this is when an application tries to read the very last block first. Many applications do this to look for an id3v1 tag (stored in the last 128 bytes of the file). When this is detected, the filesystem simply return zeros (I dont support id3v1 tags). This dramatically speeds up applications, however it could potentially lead to corrupt mp3 files if the zeros are still in kernel cache when the application comes back to read the actual audio sequentially. In my experimentation this has not happened, I always get another read for the final block.
As the file is read, it is transcoded into an internal per-file buffer. This buffer continues to grow while the file is being read until the whole file is transcoded in memory. The memory is freed only when the file is closed. This simplifies the implementation.
Seeking within a file will cause the file to be transcoded up to the seek point (if not already done). This is not usually a problem since most programs will read a file from start to finish. Future enhancements may provide true random seeking.

Usage:
mount your filesystem like this: (you will probably have to be root)
mp3fs musicdir bitrate mountpoint [-o fuse_options]
e.g.:
mp3fs /mnt/music 256 /mnt/mp3 -o allow_other,ro

LFTP is sophisticated file transfer program with command line interface. LFTP supports FTP, HTTP, FISH, SFTP, HTTPS and FTPS protocols. GNU Readline library is used for input.
Every operation in lftp is reliable, that is any non-fatal error is handled and the operation is retried automatically. So if downloading breaks, it will be restarted from the point automatically. Even if ftp server does not support REST command, lftp will try to retrieve the file from the very beginning until the file is transferred completely. This is useful for dynamic-ip machines which change their IP addresses quite often, and for sites with very bad internet connectivity.
If you exit lftp when some jobs are not finished yet, lftp will move itself to nohup mode in background. The same happens when you have a real modem hangup or when you close an xterm.
lftp has shell-like command syntax allowing you to launch several commands in parallel in background (&). It is also possible to group commands within () and execute them in background. All background jobs are executed in the same single process. You can bring a foreground job to background with ^Z (c-z) and back with command `wait (or `fg which is alias to `wait). To list running jobs, use command `jobs. Some commands allow redirecting their output (cat, ls, ...) to file or via pipe to external command. Commands can be executed conditionally based on termination status of previous command (&&, ||).
Examples:
lftp> cat file | gzip > file.gz
lftp> get file &
lftp> (cd /path && get file) &
The first command retrieves file from ftp server and passes its contents to gzip which in turn stores compressed data to file.gz. Other commands show how to start commands or command groups in background.
lftp has builtin mirror which can download or update a whole directory tree. There is also reverse mirror (mirror -R) which uploads or updates a directory tree on server.
There is command `at to launch a job at specified time in current context, command `queue to queue commands for sequential execution for current server, and much more.
LFTP supports IPv6 for both FTP and HTTP protocols. For FTP protocol it uses method described in RFC2428.
Other low level stuff supported: ftp proxy, http proxy, ftp over http, opie/skey, fxp transfers, socks.
If lftp was compiled with ssl support, then it includes software developed by the OpenSSL.
Main features:
- FTP and HTTP protocols support.
- FTP (e.g. TIS FWTK) proxy support.
- HTTP proxy support.
- FTP over HTTP proxy support (hftp).
- HTTPS and FTPS protocols support using OpenSSL library.
- Automatic OPIE/SKEY support in FTP protocol.
- FXP transfers support (between two FTP servers, bypassing client machine).
- FTP listings support: unix-style, NT, EPLF.
- Automatic reconnect and retry of an operation on retriable errors or timeout.
- IPv6 support in both FTP and HTTP.

- `mirror can download several files in parallel (--parallel option).
- Slots. Each slot is a separate session, switch using Meta-{1-9} or `slot command. Refer to a slot site using pseudo URL slot:name.

Volume Sharing Manager (Vsman) is a utility that has been designed for volume (directory) sharing management on the server side. So far, it manages NFS v3 and V4, but can be extended to others volume sharing systems.
You can select a NFS v4 server interface in the preferences dialog box. Otherwise, invoke vsman with the flag -4 in order to display the NFS v4 specific mounting options when needed.
Vsman must be run as root. It displays on the left a tree view of known directories with their possible accesses, i.e. client hosts that can mount directories from the server where vsman is running.
Each directory is displayed with a green, yellow or red spot.
Green if the directory is exported but not mounted.
Yellow when exported and mounted.
Red when unexported.
When you double-click on an access, the left side shows its mounting options.
You can obviously declare a new volume. Vsman just asks you the name of the corresponding directory. You can of course create or delete accesses for the current volume. When you create one, a dialog box appears, that asks you the suitable host name, network
name or address, or netgroup name.
If the host filed is empty, the networks field is then tested, and if empty again, the netgroup is selected.
If you select "NIS" instead of "Files" in the preferences dialog box, the hosts, networks, users and groups will be fetched from the given NIS domain name. For more info about NIS, read the corresponding HOWTO documentation.
Selecting the Reexport menu will reexport all and synchronize vsman with the exported volumes declared in /etc/exports.
Double-click on a mounting host and select Unexport Host in the Action menu, and the current volume will be unexported from the corresponding volume.
Unexport whole volume will do the same thing, but for all the mounting hosts.
The Start / Stop menu will stop or restart the NFS server.
The Save menu will write the NFS /etc/exports file and reexport all volumes.
This tool has been written in Ada 95, using gtkada 2.4 as the toolkit. Dont forget to install gnat 4.1.x or later. Gnat is now a component of the gcc suite.
Enhancements:
- A few important bugs were fixed.
- Hostname lookup was added.
- The compilation and installation process was improved.

Quagga is a routing software suite, providing implementations of OSPFv2, RIP v1 and v2, RIPv3 and BGPv4, OSPFv3 for Unix platforms, particularly FreeBSD, Linux, Solaris and NetBSD. Quagga is a fork of GNU Zebra which was developed by Kunihiro Ishiguro. The Quagga tree aims to build a more involved community around Quagga than the current centralised model of GNU Zebra.
The Quagga architecture consists of a core daemon:
zebra
Which acts as an abstraction layer to the underlying Unix kernel and presents the Zserv API over a Unix or TCP stream to Quagga clients. It is these Zserv clients which typically implement a routing protocol and communicate routing updates to the zebra daemon. Existing Zserv clients are:
ospfd
implementing OSPFv2
ripd
implementing RIP v1 and V2
ospf6d
implementing OSPFv3 (IPv6)
ripngd
implementing RIP v3 (IPv6)
bgpd
implementing BGPv4+ (including address family support for multicast and IPv6)
Additionally, the Quagga architecture has a rich development library to facilitate the implementation of protocol/client daemons, coherent in configuration and administrative behaviour.
Quagga daemons are each configurable via a network accessible CLI (called a vty). The CLI follows a style similar to that of other routing software. There is an additional tool included with Quagga called vtysh, which acts as a single cohesive front-end to all the daemons, allowing one to administer nearly all aspects of the various Quagga daemons in one place.
Enhancements:
- Numerous BGP, OSPF, and RIP bugfixes.

OpenLDAP project is an open-standard protocol for accessing X.500 directory services. The protocol runs over Internet transport protocols, such as TCP.

LDAP is a lightweight alternative to the X.500 Directory Access Protocol (DAP) for use on the Internet. It uses TCP/IP stack verses the overly complex OSI stack. It also has other simplications, such as the representing most attribute values and many protocol items as textual strings, that are designed to make clients easier to implement.
