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.
