       nntpfs - network news transport protocol (NNTP) file system

       nntpfs [ -a ] [ -s service ] [ -m mountpoint ] [ system ]

       Nntpfs  dials the TCP network news transport protocol (NNTP) port, 119,
       on  system  (default  '$nntp')  and  presents  at  mountpoint  (default
       /mnt/news)  a  file system corresponding to the news articles stored on

       If the -s option is given, the file system is posted  as  /srv/service.
       If  the  -a  option is given, nntpfs authenticates to the system with a
       user name and password obtained from factotum(4).  The key specifier is

              proto=pass service=nntp server=server user? !password?

       The file system contains a directory per newsgroup,  with  dots  turned
       into  slashes,  e.g.,  comp/os/plan9 for comp.os.plan9.  Each newsgroup
       directory contains one numbered directory per article.  The directories
       follow  the  numbering used by the server.  Each article directory con‐
       tains three files: article, header, and body.  The  article  file  con‐
       tains  the full text of the article, while header and body contain only
       the header or body.

       Each newsgroup directory contains a write-only post file  that  may  be
       used to post news articles.  RFC1036-compliant articles should be writ‐
       ten to it.  The post file will only exist in a given  newsgroup  direc‐
       tory  if articles are allowed to be posted to it.  Other than that, the
       post file is not tied to its  directory's  newsgroup.   The  groups  to
       which  articles are eventually posted are determined by the newsgroups:
       header lines in the posted article, not by the  location  of  the  post
       file in the file system.

       The  qid version of a newsgroup directory is the largest numbered arti‐
       cle directory it contains (~0, if there are no articles).

       The modification time on a newsgroup directory is the last time  a  new
       article  was recorded during this nntpfs session.  To force a check for
       new articles, stat(2) the newsgroup directory.

       To force a check for new newsgroups, stat(2) the root directory.   Note
       that  this  causes  the  entire  list  of  groups, which can be about a
       megabyte, to be transferred.

       To terminate the connection, unmount the mount point.

       Nntpfs makes no effort to send ``keepalives'' so that  servers  do  not
       hang  up  on it.  Instead, it redials as necessary when hangups are de‐

       Authenticate to a private news server:

              % echo key proto=pass service=nntp \
                   user=rsc !password=secret >/mnt/factotum/ctl
              % nntpfs -a


       Directories are presented for deleted articles; the files in them  can‐
       not be opened.
