Posting Binaries with Powerpost
You can post binary files on the Usenet network. Posting on Usenet needs a specific method since it needs some little modifications for the network itself.
Usenet was invented in 1979 to transfer text only, to exchange text between different, connected servers. Since Usenet was designed for text it is still necessary to encode binary files in a text format (yEnc coding process).
You also need a Usenet Service Provider in order to post. Almost all USPs allow their users to post as well. We recommend Eweka for various reasons:
The Peering and Feed between Eweka and other USPs is excellent.
Eweka is a Dutch service.
Their file completion is very good, no need for lots of PAR files.
For €7.50 you get 100 m/bits (special NGProvider tariff).
N.B. Copyrighted content is not allowed. Just as with downloading, you are responsible for your Usenet usage with your subscription.Encoding Binary to Text Using yEnc
A 700mo .avi file must be posted in several pieces.
For this it is cut into X .rar files (eg. 49 .rar files of 15 mo) + .PAR (Parity files are used to recreate missing data when not every part of the files reaches a server);
Then it is encoded by the posting programme: each .rar is transformed into segments of text. The number of lines in a text segment is maximum 10 000, but 5 000 is best.
On Usenet binary files are posted in the hierarchy alt.binaries. You can't post binary files into .d (discussion about the alt.binaries hierarchy) or text from Big8. Each group should match the file type.
If I post a Linux ISO I will do so in the alt.binaries.linux group. In the same way, you shouldn't post the same file in different groups at the same time. This is called crossposting and is not allowed. If you need to test something, we advise using the group alt.binaries.test which is especially for this purpose.
The fact that you can post on Usenet shows that the network is a client/server model and not P2P sharing.
There are several version of the PowerPost programme: - the eldest are Yenc-PowerPost-A&A and Power Post 2000. Nous utiliserons Camelsystem-PowerPost-ENG v2.4 qui est version améliorée
After downloading you need to configure your programme
tab Server settings
Newsserver adress: The connection address where you want to post. Here it is post.eweka.nl
Port number: Use 119
Connections: 4 connections are enough
Server Requires Login: You need to tick this box to enter connection information from your newsgroup provider. This is the same info as for downloading your Newsreader.
Username, Password & Confirm: Username and password, to confirm.
Max Bandwidth (KB/s): Enter 0 to maximise bandwidth.
Nickname: Poster name
e-mail adress: Enter a false email address so you can avoid spam, as it appears in the headers
Unique ID: Leave the default camelsystem-powerpost.local ,You can enter your own Unique ID as long as you use the .local
Enter the list of groups that interest you for your future posts. Don't forget to use the group that corresponds to your final file. There is no moderation on Usenet, so they ask you to respect their community and follow their rules.
Select desired theme: To change the programme theme.
Default yEnc-lines per part: The number of lines is important. On Usenet the binary files are encoded in the text. Each segment needs to include a maximum number of lines. 5000 is a good compromise. If you have any errors during posting, change to 3000.
Make visible which item being posted: To view posted files
Show progress dialog after pressing post: To view a new window for the post
Sort files alphabetically before queuing: To organise the files in alphabetical order
Auto-retry on errors, disconnects & timeouts: Camel Powerpost will try to repost a file if there are any errors during posting.
Minimize Powerpost to systray: To minimise the programme to an icon in the background
Autodetect .PAR2 block size: The programme will detect your PAR files. Check the box.
Move deleted items to the archive: Uncheck the box, otherwise everythign will be archived.
Create NZB file by default selected: To generate an NZB file to be posted.
Create PAR2 files by default selected: Very important. Camel Powerpost can create PAR files for reparation. This is very practical, since otherwise you would have to do so with QuickPar. When creating PAR files, leave the default
Prepare a posting
On Usenet files are posted, cut into segments as RAR. The usual size is 15mo for files of 700 mo total and 50 mo for those that are more than 3 Go.
When you select your RAR files, a window opens for the final configuration.
Apart from the post name, you can leave everything as it is.
Always post in the right group. The alt.binaries.test group is obviously dedicated to tests. Be careful about crossposting (simultaneously posting the same binary file in several groups). Maximum three groups is advisable. Usenet servers filter crossposting.
Click on OK
Let the programme load the files then Camel PP will encode the reparation files PAR
If there are a lot of them then the coding might take several minutes.Posting the Files

depending on your bandwidth the post might take several hours!
