NNTP poster is a utility that allows you to upload files and folders to USENET in bulk. The utility runs on Windows and Linux machines.

If you need to use your USENET service to upload as well as download, and have a lot of data that needs to be handled, this might be a good option.

Fair warning: some technical knowledge is required.

While other similar softwares have been discontinued or not further developed, NNTP Poster has continued to improve its program. Its most recent upgrade was released last January of 2020 which includes the following updates:

  • Modified sliced to explicitly use bytes
  • Switched target .net version to 4.7.1 to expand usable SSL/ TLS version
  • Fixed TLS 1.2 requirements from some indexers
  • Settingsloader now more lax in dealing with missing NZB post paramaters

This Usenet software is still in constant development and this is evident on the update acitivity on their github page. The latest packaged version was released in June 2021


You can download nntpPoster from GitHub. The utility does not come with an installer; you extract the downloaded files and folders to a readable and writeable directory and nntpPoster runs as a service.

Nntpposter Source Code

In order to use nntpPoster on Windows, you’ll need .Net 4.5 or newer, the RAR command line utility and the par2 command line utility.

If you’re running an OS other than windows, you’ll also need to install squlite3.

Once you have all the prerequisites installed, extract the Release folder—which is actually named “Releases” in the download—to a directory that you can read and write to.

Some file modifications are required to set the program up. Once you have everything ready to go, you can start the process nntpAutoposter.exe from the command line on windows or you can use the shell on Linux to get the service running.

This utility has only been tested on Debian 7. The developer, however, invites anyone running it on a different flavor to contact him to get an auto start script included in the package that works on that version of Linux.

Using the Program

This is not a GUI-based offering. To monitor your uploads, you’ll have to configure the logs themselves by modifying the log4netConfig.xml file.

The developer, however, recommends that you leave everything as it is for the moment.

If you have issues running the utility, you’ll want to check the log files to see what went wrong.


Uploading files to USENET is a great way to make them accessible from anywhere, but you should encrypt them first.

Fortunately, there are plenty of open-source tools that you can use to do this. VeraCrypt is an option, which happens to work on both Windows and Linux, which should make it a good choice if you plan on using nntpPoster.

There are plenty of other file encryption utilities out there. You absolutely must take this step, as anything you store on USENET is available to anyone with USENET access. If the files are encrypted, however, you should be safe.

Alternatives to NNTP Poster


If you’re technically adept and have a lot of files you need to upload to USENET, nntpPoster is worth checking out. It works on Windows and Linux. Be sure to encrypt any sensitive data you upload to a USENET server.
