# DSERVER.HOSTS - specify spool and news transit servers to backend dreaderd

# ip/host/wildcard	flags		# comment
#
# WARNING!!! dns resolution for hostnames resolved in this file are done
#	     synchronously and may stall readers.  This is on the TODO.  Use
#	     an IP address if you run into trouble.
#
# WARNING!!! when running dreaderd and diablo (feeder side) on the same 
#	     machine, don't accidently specify dreaderd's port!
#
# WARNING!!! The priority value must occur after the s or o option, something
#	     like:  sM2 will not work.  It must be 's2M'.
#	     
# flags:
#	s[#]	spool server for article fetches, w/ optional priority
#		article fetches are attempted from a random server
#		at the lowest priority until that priority is exhausted
#		by failure (a fetch may be issued on the next server
#		while still being processed by the first to reduce
#		downtime latencies). Articles are fetched using ARTICLE,
#		HEAD, BODY and STAT.
#
#	o[#]	outgoing server for POSTs, w/ optional priority
#		POSTed articles are sent to a random server at the
#		lowest priority until that priority is exhausted by
#		failure, then go on to the next priority. Articles
#		are sent to the remote server as a feed and the
#		dreaderd process must therefore have IHAVE access to
#		the remote server. This may differ from 's' access
#		and may need to have a separate line for connecting
#		to a server that doesn't allow IHAVE and ARTICLE from
#		the same connection (e.g: INN).
#
#	p#	specify port number on host
#
#	M	flag to indicate that a 'mode reader' command must be sent
#
#	R	flag to indicate that a 'mode readonly' should be sent; this
#		is mostly for use with Diablo backend spools, and to allow
#		read-only access to articles while dhistory is being rebuilt.
#
# options:
#	bind=	Set the local bind IP address/hostname
#
#	txbufsize= Set the local TCP transmit buffer size
#	rxbufsize= Set the local TCP receive buffer size
#
#	groups=	Specify the groups/hierarchies that this server holds. This
#		only applies to articles retrieved by article number, not
#		by Message-ID (we don't know the group for those), so
#		servers with limited groups will still gets requests for
#		articles they may not hold. The groups are specified as
#		a comma-delimited wildmat list. Large group lists are
#		likely to affect performance.
#
#	localspool= Specify the path to a local spool where the articles
#		can be retrieved. The normal path would be /news/spool/news.
#		If a path of '/' is specified, paths returned from the
#		spool server will be full and not relative, so the mount
#		points must be the same as the spool.
#		This is useful for an NFS mounted spool, where the
#		article path is retrieved from a remote diablo server
#		via the WHEREIS NNTP extension command.
#
#	hash= Specify which server of a group to send this request to
#	      based on a hash of the MessageID. The value is specified as
#	      n/n or n-n/n as described in dnewsfeeds.
#
#	login=	Specify an authinfo user/authinfo pass sequence needs to be
#		used to log in to the remote spool.  This is handy when
#		chaining dreaderd's between sites.  One must also specify
#		password= as well.  Note that if this option is used, the
#		initial "mode {reader,readonly}" options are ignored, as we
#		are presumably already talking to a reader and not a spool
#
#	password=	Counterpart to login=
#
#	cache=[off|on|lazy|scoring(x,y)]	Specify whether to cache
#			articles in the reader cache (if enabled in
#			diablo.config).
#			The lazy option specifies that articles will
#			only be cached if requested a second time before
#			expiration.
#			The scoring option is used to activate caching only
#			for groups "worthing" it. The first value defines
#			the read_articles/new_articles ratio at which we
#			may start to lazily cache articles. The second value
#			defines the cache_hits/read_articles at which we may
#			start to cache articles. You may use zero or a negative
#			value to activate an option for all groups.
#	cachemin=	The minimum size of articles to be cached (in bytes)
#	cachemax	The mmaximum size of articles to be cached (in bytes)=
#	cacheabletime=	Articles older than this many seconds will not be
#			added to the cache.
#
# NOTE: This file is automatically re-read when it changes, but only
#	new lines and the 's' and 'o' options make any changes to the
#	live configuration.
#	All other changes to existing lines need dreaderd to be restarted.
#	If you need to adjust an entry whilst live, comment it out,
#	wait and then uncomment.
