NAME¶
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 background.
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.
