Free nas software for linux

NAS (Network Audio System) is a network transparent, client/server audio transport system.
Network Audio System (NAS), originally developed at Network Computing Devices (NCD), includes:
Sample server implementations
- VOXware/OSS (FreeBSD, Linux, SVR4.[02], UnixWare, Microsoft Windows using Cygwin)
- HPUX (HPPA, HP-UX 10.x, 11.x)
- Sun Sparc/Intel Solaris 2.x, AM79C30A Digital Subscriber Controller and Sparc 10 Dual
- SGI Indigo (IRIX 5.x)
An application programming interface library
A variety of sample applications
Main features:
- Device-independent audio over the network
- Lots of audio file and data formats
- Can store sounds in server for rapid replay
- Extensive mixing, separating, and manipulation of audio data
- Simultaneous use of audio devices by multiple applications
- Use by a growing number of ISVs
- Small size
- Free! No obnoxious licensing terms
Enhancements:
- This version fixes several DOS attacks that could be carried out against a nasd server.
- Most of the server and client code was made ANSI compliant.
- Input and output mixer handling in the voxware (OSS) server was significantly reworked.

Radstock is a tool to analyse RADIUS traffic on high volume radius servers. It has the ability to fully decode each packet, and also has extensive filters capabilities to allow you to selectively match RADIUS packets.

It provides the ability to fully decode each packet. Here is some sample output.
The key feature of radstock is its ability to filter the packets shown based on any attribute. It will also listen out for responses to matched packets and display these as well. An example filter would be (all on one line):

radstock -e "(user-name = paul or user-name = bob) and exists nas-port-id"

To compile radstock you need the following libraries:

libpcap
flex or lex
bison/yacc

Once you have these, the following three commands should do just about
all you need.

/configure
make
make install

It has been successfully compiled on Linux and Solaris
platforms. Whether it works on them is a completely different story.

AlsaPlayer is a new type of PCM player. AlsaPlayer is heavily multi-threaded and tries to excercise the ALSA library and driver quite a bit. It has some very interesting features unique to Linux/Unix players.
The goal is to create a fully pluggable framework for playback of all sorts of media with the focus on PCM audio data. The core code was written by Andy Lo-A-Foe with contributions from many other folks. See the credits files for details.
The name AlsaPlayer might be confusing a bit today since we now support a whole bunch of different output systems.
The old default OSS audio interface is supported, as well as Esound, NAS (Network Audio Server), Sparc and SGI audio outputs. the most interesting new output is JACK. JACK is different from other audio server efforts in that it has been designed from the ground up to be suitable for professional audio work. This means that it focuses on two key areas: synchronous execution of all clients, and low latency operation.
We believe that this interface will become the preferred one. JACK uses ALSA for interfacing with the audio hardware.
Main features:
- Full speed (pitch) control, positive *and* negative!
- This is the first Linux and only GPL player that supports this. You can scratch mp3s and even audio CDs in realtime.
- Icecast/shoutcast streaming support
- Interface plugins
- Completely redefine the user interface
- Remote control
- Control alsaplayer from another application
- Low latency mode
- On capable soundcards latency can be as low as 1.3ms!
- Playlist/Queue support
- Plays nice with concurrent audio tools
- Doesnt touch the hardware mixer
- Concurrent visual scopes
- Open as many scopes as there are.
- Multi-threaded design
- This results in efficient/skip free playback. You can also activate real-time scheduling for even better performance.
- Accurate scope/audio syncing
- Portable
Supported file formats:
- Ogg Vorbis files (.ogg)
- First player worldwide that did perfect reverse Ogg playback! hehe :)
- MP3 files using MAD
- MP3 audio files using the mpg123 based plugin
- WAV files
- CDDA, CD Digital Audio playback (digital ripping), with CDDB lookup
- All MODULES supported by MikMod
- All file types supported by the Audio File Library
- FLAC files. A lossless compression scheme
Supported sound systems:
JACK
- A low-latency audio server, written primarily for the Linux operating system. It can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves.
ALSA
- The next-generation audio interface for Linux. ALSA was recently merged in the 2.5.x Linux tree. It has many advantages over the old OSS interface.
OSS
- The old Linux audio API. This is still widely used.
SGI
- For SGI (IRIX) systems, using the SGI audio library.
NAS
- Network Audio Server. X11 for audio if you will.
ESD
- Esound, found in GNOME.
- Null
- Nosound driver, useful for testing

Libao is a cross-platform audio library that allows programs to output audio using a simple API on a wide variety of platforms.
Libao began life as cross-platform audio library inside of ac3dec, an AC3 decoder by Aaron Holtzman that is part of the LiViD project. When ogg123 (part of the command line vorbis tools) needed a way to play audio on multiple operating systems, someone on the vorbis-dev mailing list suggested the libao library as a possible way to add cross-platform support to ogg123. Stan Seibert downloaded the libao library, severely
hacked it up in order to make the build process simpler and support multiple live-playback devices. (The original code allowed one live playback driver, the wav driver, and a null driver to be compiled into the library.) Jack Moffitt got it supporting dynamically loaded plugins so that binary versions of libao could be provided.
Main features:
- Null output (handy for testing without a sound device)
- WAV files
- AU files
- OSS (Open Sound System, used on Linux and FreeBSD
- ALSA (Advanced Linux Sound Architecture)
- polypaudio (next generation GNOME sound server)
- esd (EsounD or Enlightened Sound Daemon)
- AIX
- Sun/NetBSD/OpenBSD
- IRIX
- NAS (Network Audio Ser
Enhancements:
- New Polypaudio driver (libao-polyp 0.4) contributed by Lennart Poettering
- Use esd_close() in the esd driver
- Broaden sample rate tolerance in the OSS driver for nForce compatibility

XAnim project is a program for playing a wide variety of animation, audio and video formats on unix X11 machines.
I attempt to reply to all the email messages I receive, however, I get quite a few with invalid return addresses. If you dont hear from me within a week, double check that your return address is correct.
XAnim X11 Support
XAnim supports the majority of the common X11 Visuals. It supports all depths that have a bpp of 1, 8, 16 and 32. Other bpps are non-standard(although they are legal). NOTE: that the depth indicates how many bits are used to specify the color of a pixel and the bpp indicates how many bits each pixel consumes in memory. For example, a depth 24 Visual usually has a 32 bpp uses 24 bits to specify the color and 8 bits of padding per pixel.
Since I optimize each video decompression routine(currently over sixty of them) for each bpp, its a lot of work when someone decides to use a "non-standard" bpp. Especially when the bpp doesnt have a correspondingly sized variable(like bytes for depth 8 or shorts for depth 16). This is why bpp 24 is not yet supported.
XAnim also supports X11 shared memory. This can greatly speed up the drawing of images on most X11 servers by eliminating the need for the X11 server to copy the image *before* writing the image to the display memory. NOTE: X11 shared memory isnt possible when you are using a remote display(ie: you are running on one machine and sending the display to another).
XAnim Audio Support
Unix doesnt have anything even remotely resembling an audio standard or API. This means separate and unique code must be written for each OS/machine combination that is to be supported.
Below is a list of the currently support platforms. If you have a platform that isnt currently supported and you would like to help write the code for it, let me know and I can provide you with some assistance, etc.
- Linux x86 platforms.
- NetBSD x86 platforms.
- BSDI x86 platforms.
- FreeBSD x86 platforms.
- SGI workstations(Indy, Indigo, etc).
- DEC workstations running MMS(Multimedia Services).
- Sun Solaris/SunOS Sparc/68K/x86 workstations.
- HP workstation running HPs Aserver.
- HP workstation direct audio device.
- Sony NEWS 5000 series workstations.
- QNX 4.2 x86 platforms.
- NEC EWS workstations.
- IBM AIX 4.1 workstations.
- Any machine running AudioFile(AF).
- Any machine running Net Audio Server(NAS).
Some time this year I plan on revamping the audio device section of XAnim to allow multiple audio devices to be compiled in at once. For example if you have a Solaris Sparc platform, you could then compile in support for the native audio device and NAS at the same time. That way you could use the same xanim executable depending on whether the machine youre on is running NAS or not.
The reason I bring this up is because I suspect I will probably break things left and right for a while and since I dont have access to the majority of these platforms, I wont be able to test them out before releasing. In any case, when the time comes, Ill give plenty of warning and will leave the old release around.

radutmped is a utility that can remove utmp entries from radutmp files of several RADIUS servers. The project directly manipulates the radutmp file and does not use radzap or any other programs.

FreeRADIUS, Cistron Radius Server and GNU Radius radutmp formats are supported. Three search modes are available, radutmped can match entries in radutmp by login (User-Name), nas_port (NAS-Port) or session_id (Acct-Session-Id).

COMPILING:

- Edit Makefile to change CC, CFLAGS or LDFLAGS if necessary.

- Execute make:
# make

- Only one RADIUS server can be supported in the radutmped binary, you have to
choose which.
By default, FreeRADIUS support will be compiled in, to change, pass along an
environment variable RADUTMP_TYPE when issuing make:

For Cistron support use RT_CISTRON as the variable value:
# RADUTMP_TYPE=RT_CISTRON make

For GNU Radius support use RT_GNURADIUS as the variable value:
# RADUTMP_TYPE=RT_GNURADIUS make

- Move the compiled binary radutmped somewhere:
# mv radutmped /usr/local/sbin

USAGE:

# radutmped L |P |S

EXAMPLES:

- Find out session details for user john (example with FreeRADIUS):
# radwho -r -i | grep john
john,0011AA22,PPP,S123456,Thu 08:21,192.168.1.254,192.168.10.123

The output line contains the following data:
User-Name: john
Acct-Session-Id: 0011AA22
Framed-Protocol: PPP
NAS-Port: 123456
NAS-IP-Address: 192.168.1.254
Framed-IP-Address: 192.168.10.123

Mind that the S character in the nas_port field has to be left out
when using radutmped.

- Remove a radutmp entry for session_id 0011AA22:
# radutmped /var/log/radius/radutmp S0011AA22

- Remove a radutmp entr-y/-ies for nas_port 123456
# radutmped /var/log/radius/radutmp P123456

- Remove a radutmp entr-y/-ies for login john:
# radutmped /var/log/radius/radutmp Ljohn

sc101-nbd allows Linux to access a Netgear SC101 storage device as a block device, without requiring a new kernel module.
Netgear Storage Central 101 (sc101) is an IP based block storage device.
Netgear ships a clustered filesystem with the product (perhaps based on DataPlow SFS) which allows multiple Windows client machines to concurrently mount and read/write directly to the device; it is a SAN rather than a NAS device.
There is no protocol documentation provided, nor any driver support for operating systems other than Windows.
This software allows Linux to access the the sc101 as a block device, without requiring a new kernel module.
It achieves this by translating between the kernels existing NBD protocol and the reverse engineered protocol used by the sc101 (I call it PSAN, perhaps incorrectly).
On top of the NBD devices you can run RAID, LVM, and any existing filesystems (ext2/3, ocfs2, etc).
The resulting storage area is not interoperable with existing Windows clients.
It is unknown whether this software is compatible with the (unreleased) sc101t or other Zetera partnered devices.
Enhancements:
- This has been tested on RHEL/CentOS 4.x and Ubuntu 7.04.
