       The "Net::NNTP" module must be installed.  This module is available as
       part of the libnet distribution and comes with recent versions of Perl.
       For older versions of Perl, you can download it from

       pullnews reads a config file named pullnews.marks, and connects to the
       upstream servers given there as a reader client.  This file is looked
       for in pathdb when pullnews is run as the user set in runasuser in
       inn.conf (which is by default the "news" user); otherwise, this file is
       looked for in the running user's home directory.

       By default, pullnews connects to all servers listed in the
       configuration file, but you can limit pullnews to specific servers by
       listing them on the command line:  a whitespace-separated list of
       server names can be specified, like from-server for one of them.  For
       each server it connects to, it pulls over articles and feeds them to
       the destination server via the IHAVE or POST commands.  This means that
       the system pullnews is run on must have feeding access to the
       destination news server.

       pullnews is designed for very small sites that do not want to bother
       setting up traditional peering and is not meant for handling large

       -a hashfeed
           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 to a generate 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.

       -b fraction
           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

       -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.

       -c config
           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.

       -C width
           Use width characters per line for the progress table.  The default
           value is 50.

       -d level
           Set the debugging level to the integer level; more debugging output
           will be logged as this increases.  The default value is 0.

       -f fraction
           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

       -F fakehop
           Prepend fakehop as a host to the Path: header of articles fed.

       -g groups
           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.

       -G newsgroups
           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.

       -H headers
           Remove these named headers (colon-separated list) from fed

       -k checkpt
           Checkpoint (save) the config file every checkpt articles (default
           is 0, that is to say at the end of the session).

       -l logfile
           Log progress/stats to logfile (default is "stdout").

       -m header_pats
           Feed an article based on header matching.  The argument is a number
           of whitespace-separated tuples (each tuple being a colon-separated
           header 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 matches "regexp1" and the "Hdr2:" header does not match
           "regexp2".  Besides, if the "Hdr3:" header matches "regexp3", that
           header is removed; and if the "Hdr4:" header does not match
           "regexp4", that header is removed.

       -M num
           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.

       -N timeout
           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.

       -p port
           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.

       -P hop_limit
           Restrict feeding an article based on the number of hops it has
           already made.  Count the hops in the Path: header (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

       -q  Print out less status information while running.

       -Q level
           Set the quietness level ("-Q 2" is equivalent to "-q").  The higher
           this value, the less gets logged.  The default is 0.

       -r file
           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.  The default is to use the IHAVE command.

       -s to-server[:port]
           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.

       -S max-run
           Specify the maximum time max-run in seconds for pullnews to run.

       -t retries
           The maximum number (retries) of attempts to connect to a server
           (see also -T).  The default is 0.

       -T connect-pause
           Pause connect-pause seconds between connection retries (see also
           -t).  The default is 1.

       -w num
           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 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.

       -z article-pause
           Sleep article-pause seconds between articles.  The default is 0.

       -Z group-pause
           Sleep group-pause seconds between groups.  The default is 0.

       The config file for pullnews is divided into blocks, one block for each
       remote server to connect to.  A block begins with the host line (which
       must have no leading whitespace) and contains just the hostname of the
       remote server, optionally followed by authentication details (username
       and password for that server).  Note that authentication details can
       also be provided for the downstream server (a host line could be added
       for it in the configuration file, with no newsgroup to fetch).

       Following the host line should be one or more newsgroup lines which
       start with whitespace followed by the name of a newsgroup to retrieve.
       Only one newsgroup should be listed on each line.

       pullnews will update the config file to include the time the group was
       last checked and the highest numbered article successfully retrieved
       and transferred to the destination server.  It uses this data to avoid
       doing duplicate work the next time it runs.

       The full syntax is:

           <host> [<username> <password>]
                   <group> [<time> <high>]
                   <group> [<time> <high>]

       where the <host> line must not have leading whitespace and the <group>
       lines must.

       A typical configuration file would be:

           # Format group date high
                   rec.bicycles.racing 908086612 783
                   rec.humor.funny 908086613 18
           nnrp.vix.com pull sekret

       Note that an earlier run of pullnews has filled in details about the
       last article downloads from the two rec.* groups.  The two comp.*
       groups were just added by the user and have not yet been checked.

       The nnrp.vix.com server requires authentication, and pullnews will use
       the username "pull" and the password "sekret".

           The Perl script itself used to pull news from upstream servers and
           feed it to another news server.

       pathdb/pullnews.marks or ~/pullnews.marks
           The default config file.  It is stored in pullnews.marks in pathdb
           when pullnews is run as the news user, or otherwise in the running
           user's home directory.

       pullnews was written by James Brister for INN.  The documentation was
       rewritten in POD by Russ Allbery <eagle@eyrie.org>.

       Geraint A. Edwards greatly improved pullnews, adding no more than
       16 new recognized flags, fixing some bugs and integrating the
       backupfeed contrib script by Kai Henningsen, adding again 6 other
