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.
