-ahashfeed
This option is a deterministic way to control the flow of articles and to split a feed. The hashfeed
parameter must be in the form "value/mod" or "start-end/mod". The Message-ID of each article is
hashed using MD5, which results in a 128-bit hash. The lowest 32 bits are then taken by default as
the hashfeed value (which is an integer). If the hashfeed value modulus "mod" plus one equals
"value" or is between "start" and "end", pullnews will feed the article. All these numbers must be
integers.
For instance:
pullnews -a 1/2 Feeds about 50% of all articles.
pullnews -a 2/2 Feeds the other 50% of all articles.
Another example:
pullnews -a 1-3/10 Feeds about 30% of all articles.
pullnews -a 4-5/10 Feeds about 20% of all articles.
pullnews -a 6-10/10 Feeds about 50% of all articles.
You can use an extended syntax of the form "value/mod:offset" or "start-end/mod:offset" (using an
underscore "_" instead of a colon ":" is also recognized). As MD5 generates a 128-bit return value,
it is possible to specify from which byte-offset the 32-bit integer used by hashfeed starts. The
default value for "offset" is ":0" and thirteen overlapping values from ":0" to ":12" can be used.
Only up to four totally independent values exist: ":0", ":4", ":8" and ":12".
Therefore, it allows generating a second level of deterministic distribution. Indeed, if pullnews
feeds "1/2", it can go on splitting thanks to "1-3/9:4" for instance. Up to four levels of
deterministic distribution can be used.
The algorithm is compatible with the one used by Diablo 5.1 and up.
-bfraction
Backtrack on server numbering reset. Specify the proportion ("0.0" to "1.0") of a group's articles
to pull when the server's article number is less than our high for that group. When fraction is
"1.0", pull all the articles on a renumbered server. The default is to do nothing.
-B Feed is header-only, that is to say pullnews only feeds the headers of the articles, plus one blank
line. It adds the Bytes header field if the article does not already have one, and keeps the body
only if the article is a control article.
-cconfig
Normally, the config file is stored in pullnews.marks in pathdb when pullnews is run as the news
user, or otherwise in the running user's home directory. If -c is given, config will be used as the
config file instead. This is useful if you're running pullnews as a system user on an automated
basis out of cron or as an individual user, rather than the news user.
See "CONFIG FILE" below for the format of this file.
-Cwidth
Use width characters per line for the progress table. The default value is "50".
-dlevel
Set the debugging level to the integer level (up to "4"); more debugging output will be logged as
this increases. The default value is "0".
-ffraction
This changes the proportion of articles to get from each group to fraction and should be in the range
"0.0" to "1.0" ("1.0" being the default).
-Ffakehop
Prepend fakehop as a host to the Path header field body of articles fed.
-ggroups
Specify a collection of groups to get. groups is a list of newsgroups separated by commas (only
commas, no spaces). Each group must be defined in the config file, and only the remote hosts that
carry those groups will be contacted. Note that this is a simple list of groups, not a wildmat
expression, and wildcards are not supported.
-Gnewsgroups
Add the comma-separated list of groups newsgroups to each server in the configuration file (see also
-g and -w).
-h Print a usage message and exit.
-Hheaders
Remove these named header fields (colon-separated list) from fed articles.
-kcheckpt
Checkpoint (save) the config file every checkpt articles (default is "0", that is to say at the end
of the session).
-llogfile
Log progress/stats to logfile (default is "stdout").
-Lsize
Specify the largest wanted article size in bytes. The default is to download all articles, whatever
their size. When this option is used, pullnews will first retrieve overview data (if available) of
each newsgroup to process so as to obtain articles sizes, before deciding which articles to actually
download.
-mheader_pats
Feed an article based on header field body matching. The argument is a number of whitespace-
separated tuples (each tuple being a colon-separated header field name and regular expression). For
instance:
-m "Hdr1:regexp1 !Hdr2:regexp2 #Hdr3:regexp3 !#Hdr4:regexp4"
specifies that the article will be passed only if the "Hdr1" header field body matches "regexp1" and
the "Hdr2" header field body does not match "regexp2". Besides, if the "Hdr3" header field body
matches "regexp3", that header is removed; and if the "Hdr4" header field body does not match
"regexp4", that header is removed.
-Mnum
Specify the maximum number of articles (per group) to process. The default is to process all new
articles. See also -f.
-n Do nothing but read articles -- does not feed articles downstream, writes no rnews file, does not
update the config file.
-Ntimeout
Specify the timeout length, as timeout seconds, when establishing an NNTP connection.
-O Use an optimized mode: pullnews checks whether the article already exists on the downstream server,
before downloading it. It may help for huge articles or a slow link to upstream hosts.
-pport
Connect to the destination news server on a port other than the default of "119". This option does
not change the port used to connect to the source news servers.
-Phop_limit
Restrict feeding an article based on the number of hops it has already made. Count the hops in the
Path header field body (hop_count), feeding the article only when hop_limit is "+num" and hop_count
is more than num; or hop_limit is "-num" and hop_count is less than num.
-q Print out less status information while running.
-Qlevel
Set the quietness level ("-Q 2" is equivalent to "-q"). The higher this value, the less gets logged.
The default is "0".
-rfile
Rather than feeding the downloaded articles to a destination server, instead create a batch file that
can later be fed to a server using rnews. See rnews(1) for more information about the batch file
format.
-R Be a reader (use MODE READER and POST commands) to the downstream server. Some posts will then be
rejected because of unexpected injection header fields, obsolete or incorrectly formatted header
fields, or with a date too far in the past. You may then want to set artcutoff to "0" in inn.conf,
and use the -H flag to strip unwanted header fields. Even with that, a few articles may still be
rejected.
The default is to behave like a feeder and use the IHAVE command. (You'll have to allow in
incoming.conf the connections from pullnews so that it is recognized as a feeder.)
-sto-server[:port][_tlsmode]
Normally, pullnews will feed the articles it retrieves to the news server running on localhost. To
connect to a different host, specify a server with the -s flag. You can also specify the port with
this same flag or use -p. Default port is "119".
The connection is by default unencrypted. To negotiate a TLS encryption layer, you can set tlsmode
to "TLS" for implicit TLS (negotiated immediately upon connection on a dedicated port) or "STARTTLS"
for explicit TLS (the appropriate command will be sent before authenticating or feeding messages).
Examples of use are:
pullnews -s news.server.com
pullnews -s news.server.com_STARTTLS
pullnews -s news.server.com:433_TLS
Note that not all NNTP servers implement TLS for feeding articles.
-Smax-run
Specify the maximum time max-run in seconds for pullnews to run.
-tretries
The maximum number (retries) of attempts to connect to a server or reconnect to a server if the
socket is unexpectedly closed (see also -T). The default is "0".
-Tconnect-pause
Pause connect-pause seconds between connection retries (see also -t). The default is "1".
-wnum
Set each group's high water mark (last received article number) to num. If num is negative,
calculate Current+num instead (i.e. get the last num articles). Therefore, a num of "0" will re-get
all articles on the server; whereas a num of "-0" will get no old articles, setting the water mark to
Current (the most recent article on the server).
-x If the -x flag is used, an Xref header field is added to any article that lacks one. It can be
useful for instance if articles are fed to a news server which has xrefslave set in inn.conf.
-zarticle-pause
Sleep article-pause seconds between articles. The default is "0".
-Zgroup-pause
Sleep group-pause seconds between groups. The default is "0".
