HELLO(8) System Manager's Manual HELLO(8)NAME
HELLO - perform initial conversation with a newsserver (used by sn news system)
SYNOPSIS
HELLO
DESCRIPTION
HELLO is the program that gets executed for every newsserver by the snget(8) program. There is a connection to the newsserver, but nothing
has been sent or received yet. This program handles the initial contact. File descriptors 6 is used for data coming from the newsserver,
and descriptor 7 is used for data going to the newsserver.
This program is used by the sn news system.
You never have to use this program yourself. However, when a newsserver is non-standard, you may have to modify a copy of it for that
server. Newsserver-specific copies should go into /var/spool/sn/.outgoing/HOST

snget,sngetd - fetch news from upstream sites and store them locally.
SYNOPSIS
snget [options] [news.group...]
sngetd [options]
options: [-d] [-h Bps] [-p nparallel] [-c depth] [-m max]
DESCRIPTION
snget fetches articles for the news.groups on the command line (or all non-local newsgroups if none are specified) from their respective
upstream feeds, and stores them in the news spool /var/spool/sn. If a newsgroup could not be fetched for, it may be attempted again.
sngetd does the same, except it reads newsgroup names from /var/spool/sn/.fifo and does not exit. sngetd does not fork into the back-
ground.
snget does not guarantee to fetch the groups in the order specified on the command line. snget and sngetd will write errors and status
messages to descriptor 2.
snget and sngetd are both scheduling wrappers that call /usr/sbin/SNHELLO, snfetch, and snstore. You must own /var/spool/sn or be root in
order to run snget and sngetd.
OPTIONS -d Enable verbosity, may be specified multiple times. This option is also propagated to snfetch and snstore.
-p nparallel
Attempt to fetch for nparallel newsgroups at once. Default is 4, maximum is 8.
-h Bps Throttle the sum of bandwidth used by all snfetches to Bps bytes per second. This option is used to prevent snget or sngetd from
hogging the network. By default there is no throttling.
-c depth
depth is passed to snfetch as the depth of the command pipeline.
-m max The very first time contacting the news server, retrieve no more than max articles per newsgroup, default is 200. This option is
useful only if there are unprimed newsgroups and has no effect otherwise. The .max file in each newsgroup directory still applies
(see snfetch(8)).
-t timeout
This option is not documented because it is ignored and will disappear in a future release. See .timeout in FILES next.
FILES
Server Directories
These are the directories /var/spool/sn/.outgoing/server.name:port, which are symlinked from /var/spool/sn/news.group/.outgoing. If
the latter isn't a (symlink to a) directory, snget won't fetch for news.group.
/var/spool/sn/.outgoing/server.name:port/.timeout
If this file exists and contains a number, this is taken to be the timeout in seconds in all dealings with server.name:port.
Default is 120 seconds.
/var/spool/sn/.outgoing/server.name:port/.SNHELLO
If this program file exists, it is invoked instead of the default (usually /usr/sbin/SNHELLO) when an NNTP connection is first made
to server.name:port in order to read the greeting and upload posted articles. If server.name:port requires a username and password,
you would copy the default here and edit that information in.
/var/spool/sn/news.group/{.serial,.max}
snget and sngetd read these files on behalf of snfetch.
SIGNALS
Other signals have default behaviour.
SIGUSR1
If -h Bps was specified, Bps is halved, else is ignored.
SIGUSR2
If -h Bps was specified, Bps is doubled, else is ignored.
ENVIRONMENT VARIABLES
See also /usr/sbin/SNHELLO for the list of environment variables exported by snget/sngetd.
SNROOT If this is set and is not empty, the value is used in place of /var/spool/sn, the default news spool directory.
PATH To find SNHELLO (if this server does not have a .SNHELLO), snfetch, and snstore. If PATH does not contain /usr/sbin as one of it's
components, /usr/sbin is appended to it.
