Copyright note ============== ==> four week free trial period ==> free for approved non-profit organisations like schools or universities. But you still need to *register* your free copy of DNEWS News Server to get the free license key. ==> *payware* for other people and organisations More Infos ========== http://netwinsite.com/ DNEWS Feature list ================== Dynamic sucking feed. A sucking feed may use as little as 10% of the normal disk space and network bandwidth. By only getting news items that people usually read very large savings are possible particularly for small sites & workgroups. A hundred users can be supported on 100 MB depending on their reading habbits! I run a single user server on my NT as a background service, it's using less than 5MB. Flexible expire settings By allowing expiration by 'number of items' low volume groups become much more useful. Also by allowing settings which change with disk space the system is much more stable to large influxes of news. Flexible access restrictions Reading and Posting access can be given separately to to different users and selections of news groups. Binarys available for common platforms On many platforms you do not need to build the binary yourself, e.g. VMS, (VAX & ALPHA), Solaris, Linux, Windows NT Email confirmation of posts DNEWS can be configured to send email confirmations as it sends items up to a main news server. This gives users a clear record of a posted item and it's successful transfer into the 'net'. Items stored in a database Items are stored in a database which puts items together in blocks of 100. This saves directory entries, inodes, and the empty space usually wasted due to blocking factors. Also file open and closes are minimized, this is essential on systems where this is a 'costly' operation, e.g. VMS. Compiling and porting relatively easy DNEWS was designed to be portable from the ground up, it does not rely on obscure UNIX features. Installation easy, totally configurable without recompiling DNEWS can be configured without recompiling and all the configuration scripts have been simplified where possible. Documentated A user manual is available. Supported EMAIL support is available for help with installation and management. Speed On comparable systems DNEWS typically out performs other news software, (even the likes of CNEWS and INN in some instances), other VMS news servers don't even come close. This is partly because DNEWS uses a more advanced database to store the news items. The difference is also very noteable on smaller systems (e.g. Linux) XOVER implemented in software No xover database is created, the normal DNEWS database is fast enough to create this information 'on the fly' Streaming support Streaming NNTP extensions are built in. Strictly limited machine impact due to single threaded nature. DNEWS runs on a single process, this speeds up connect time as a process does not need to be created, and it self-limits the impact on the system. Limitations =========== DNEWS does not store items in the same file structure as used by INN and CNEWS, so old software which accesses these files directly will not work.
