Free par2 software for linux

par2repair is a useful script to fix par2 files. Just add it to your /servicemenus/ folder and right click on any par2 files.

Its my first script so its pretty straight forward.

Parchive project is a tool that helps data recovery of multi-part archives on Usenet.

The original idea behind this project was to provide a tool to apply the data-recovery capability concepts of RAID-like systems to the posting and recovery of multi-part archives on Usenet. We accomplished that goal. Our new goal with version 2.0 of the specification is to improve.

It extends the idea of version 1.0 and takes the recovery process beyond the file-level barrier. This allows for more effective protection with less recovery data, and removes some previous limitations on the number of recoverable parts. See Par1 compared to Par2 for a more detailed view of the differences.

Because this new approach doesnt benefit from like sized files, it drastically extends the potiental applications of PAR. Files such as video, music, and other data can remain in a usable format and still have recovery data associated with them.

The technology is based on a Reed-Solomon Code implementation that allows for recovery of any X real data-blocks for X parity data-blocks present. (Data-blocks referring to files OR much smaller virtual slices of files).

The key to this mission is a clean file format specification which provides all the necessary capabilities for programs to easily verify and regenerate single missing parts out of a set of data-blocks.

nget is a command line nntp file grabber. It automatically pieces together multipart postings for easy retrieval, even substituting parts from multiple servers. Handles disconnects and resuming very well.
nget is developed on linux (glibc2), and has been successfully compiled/tested
on: linux x86(gcc 2.95.4, gcc 3.0.4, gcc 3.2, gcc 3.3), linux alpha(gcc 2.95.2), macosx(gcc 2.95.2), freebsd x86(gcc 2.95.4, gcc 3.0.4), solaris sparc(gcc 2.95.2), win32(mingw or cygwin) and should compile without modifications on other systems using g++ 2.95+ or other up to date compliers. Older compilers like gcc 2.7.x can no longer build nget, but can (probably) still build ngetlite, so you can still use it to download on an older comp if you have a recent comp that you can use nget to write the listfiles on (-w option).
Main features:
- Automatic multi-part post joining
- Automatic binary decoding (using uulib)
- Caches header data for quick access
- Full multi-server support, transparently joining parts from different servers
- Full multi-group support, transparently joining parts from multiple newsgroups
- Automatic retries on network errors
- Resumes after the last part successfully downloaded
- Dupe file detection to avoid unneeded downloads
- Select what to retrieve based upon a regular expresson (-r), or even a more complex expression (-R) based upon any of the files subject, author, lines, bytes, # of parts we have, # of parts req, date, age, messageid, and references.
- Search for newsgroups based on their names and/or descriptions
- Automatic handling of PAR and PAR2 files retrieves only as many recovery files as necessary to repair any missing/damaged files.
Enhancements:
- Fix error in configure script when printing exceptions not found message, due to unquoted string. (Reported by M.J. Soft)
- Fix -G* when NGETCACHE != NGETHOME. (Reported by Steven Adeff)
- Fix midinfo and newsgroups files not honoring NGETCACHE/cachedir setting. (Reported by Christian Marillat)
- Allow absolute paths in --text=mbox: . (Requested by Volker Wysk)
- Support tab as the field separator in XPAT results, for Newsplex server support. (Requested by Mark Blain)
- -a no longer gives an error if the server doesnt support LIST NEWSGROUPS(which retrieves newsgroup descriptions.)
- Fix printing a warning when loading newsgroups list which contains descriptions of groups which no server actually carries. (Reported by Frederick Bruckman)
- Fix problems loading group descriptions from newsgroups list which contain tabs. (Reported by Frederick Bruckman)

cfv is a utility to both test and create .sfv, .csv, .crc, .md5(sfv-like), md5sum, bsd md5, sha1sum, and .torrent files. These files are commonly used to ensure the correct retrieval or storage of data.
cfv is written in python, and as such should run on all platforms python supports. Currently, it has been verified to work on linux, freebsd, openbsd, netbsd, solaris, macosx, and windows.
Main features:
- supports testing and creating of .sfv, .csv(2, 3, and 4 field variants), .crc, sfvmd5(sfv file using md5 instead of crc32), md5sum, bsd md5, sha1sum, and BitTorrent file formats
- test-only support for PAR and PAR2 files
- automatic checksum file naming ability in create mode
- recursive operation
- show unverified files option
- ignore case and fix path seperator options for cross platform use
- transparent gzip support for checksum files
- configurable renaming of bad files (with testing against previous bad files, to save only unique differing copies)
- searching for/fixing of misnamed files
- raw listing of files of specified type (bad, missing, etc)
- test suite to ensure correct operation
