Since I keep forgetting how to prepare my binaries from the CLI, I thought it would be better if I wrote it online for future reference. Perhaps someone will find it useful as well.
This howto I will show how you can split archives into bits and make parity files from the CLI.
You will need non-free software to do the following steps.
First we need necessary software, namely rar to archive and split the binaries, and then par2 for error correction during download.
- Code: Select all
# apt-get install rar par2
Let is assume I have the file debian-8.6.0-i386-netinst.iso inside my home directory, with the path /home/hallvor/debian-8.6.0-i386-netinst.iso
I then issue the following command:
- Code: Select all
$ rar a debian-8.6.0-i386-netinst.rar -v50m -m0 debian-8.6.0-i386-netinst *
This command will start rar and create several archives, starting with a file called debian-8.6.0-i386-netinst.rar. -50m means that rar will split the archives into file sizes of 50 megabytes. -m0 means no compression, 3 is default and 5 is best. The iso will be stored inside a folder named debian-8.6.0-i386-netinst when it is extracted, and the * means all files in the directory will be appended. The advantage of creating a folder for the extracted file is especially apparent for a multi-file archive, where files otherwise could be accidentally mixed with others.
Parity files will make your Usenet client able to repair downloads with errors.
You can now remove the .iso from the directory.
Issue the following command to create parity files:
- Code: Select all
$ par2create "debian-8.6.0-i386-netinst" -r20 -n10 *.rar
-r20 means it will create parity files of 20% redundancy, and -n10 means 10 files.
The parity files can be verified with
- Code: Select all
$ par2verify *.par2
The files are now ready to be uploaded.
Uploading files
There are not many options available for uploading files if you want to use open source software on GNU/Linux. One of the most popular ones with a GUI is JBinUp. It works well, uses Java, but is closed source. Other options are newspost, bur unfortunately it hasn't been under active development since more than a decade. Then there is sanguinews - a very good CLI usenet uploader for GNU/Linux.
Sanguinews is not in the official repositories, so we need build-essential and ruby-dev to install it.
- Code: Select all
# apt-get install build-essential ruby-dev
You can now install sanguinews as a gem
- Code: Select all
# gem install sanguinews
Now we need to put a config file called .sanguinews in your /home directory (as regular user)
- Code: Select all
$ nano ~/.sanguinews.conf
Paste this content into the file
- Code: Select all
# Sample config file
# Groups to post to
# Separate multiple groups with comma
groups = alt.binaries.test
# Your identity
from = witty_nickname <whatever@example.com>
# Username to use for authentication
username = your_username
# Password
password = your_password
# server to use
server = your_server
# Use SSL connection?
ssl = yes
# port
port = 563
# number of connections
connections = 10
# article size in bytes
article_size = 768000
# Wait this many seconds before trying to reconnect after unsuccessful upload
reconnect_delay = 5
# Subject prefix to use
prefix = "[sanguinews] - "
# Enable nzb creation
nzb = yes
# Use header checking? Upload will be slow but reliable.
header_check = no
# Debug information
debug = no
#######################
# headers
#######################
# X-No-Archive
xna = no
You need to at least edit the following parts: groups (to post to), username, password and server.
After you have finished editing everything, press Ctrl + X, and then Y to save the changes.
You can find different options for sanguinews by typing sanguinews --help
hallvor@debian-hp:~$ sanguinews --help
- Code: Select all

sanguinews is a simple nntp(usenet) binary poster. It supports multithreading and SSL. More info in README.
Usage: sanguinews [OPTIONS] [DIRECTORY] | -f FILE1..[FILEX]
Options
-c, --config CONFIG use different config file
-C, --check check headers while uploading; slow but reliable
-f, --file FILE upload FILE, treat all additional parameters as files
-g, --groups GROUP_LIST use these groups(comma separated) for upload
-h, --help help
-p, --password PASSWORD use PASSWORD as your password(overwrites config file)
-r, --recursive process all files under each directory recursively
-u, --user USERNAME use USERNAME as your username(overwrites config file)
-v, --verbose be verbose?
-V, --version print version information and then exit
hallvor@debian-hp:~$
Let's upload something and assume that I put all the files above in ~/upload
The files can then be uploaded with
- Code: Select all
$ sanguinews -v /home/hallvor/upload/
