It can be scheduled with cron to run daily. It is advisable#     to use a long encryption password since everyone can download your #     backup and try to bruteforce it. The encryption cipher used is approved#     by the NSA for 'top secret'-classified documents, and should be#     sufficient for personal use.##    Usage:#     1. Configure the variables in the script#     2. Run the script with two arguments:#         1. the name of the file you want to upload (single file, use tar)#         2. the name of the posting you want to use in the usenet upload##    Example:#     ./newsUpload.sh photoAlbum.tgz username-photoAlbum##    If the upload was succesfull (no errors, check logfile), your upload#     should appear on sites like binsearch.net and nzbindex.nl after 20-30#     minutes. You can then download/par/unrar the files with your normal news#     download program and decrypt the files using the following command:##     $ openssl enc -d -salt -in <filename>.enc -out <filename>##    Dependencies:#     - rar (tested with RAR 3.93)#     - par2 (tested with par2cmdline 0.4)#     - openssl (tested with OpenSSL 0.9.8o)#     - newspost (tested with newspost 2.1.1,http://newspost.unixcab.org)##    Variables used in the script:#     TMPDIR - Temporary directory where the script can put the generated#               rar and par files. This directory should have enough space for#               the file to be uploaded + 10 % (par files)##     LOGFILE - Path to a logfile, should be writable# #     ENCPW - Password used for the OpenSSL encryption. Please use a very long#              string as everyone can download your file and try to bruteforce##     NEWSSERVER - Hostname or IP address of your newsserver##     NEWSUSER - Optional - Username to be used with your newsserver##     NEWSPASS - Optional - Password to be used with your newsserver##     NEWSMAIL - Mail address used in the From: field for the Usenet postings##     NEWSGROUP - Newsgroup to post to#
