SYNOPSIS

11       nntpd [ -C config-file ] [ -U uses ] [ -T timeout ] [ -D ]

DESCRIPTION

15       nntpd  is an NNTP server. It accepts commands on its standard input and
16       responds on its standard output. It  MUST  invoked  by  master(8)  with
17       those descriptors attached to a remote client connection.
18
19       nntpd  reads  its  configuration  options out of the imapd.conf(5) file
20       unless specified otherwise by  -C.   The  optional  newsprefix  setting
21       specifies  a prefix to be prepended to newsgroup names to make the cor‐
22       responding IMAP mailbox names.  The optional newspostuser setting spec‐
23       ifies  the  special  userid to be used when constructing the To: header
24       address for following up to articles when read via IMAP.  The  optional
25       newspeer setting specifies the fully qualified hostname of the upstream
26       news server to which articles are fed.  The optional allownewnews  set‐
27       ting enables the NNTP NEWNEWS command.
28
29       NOTE:
30          For servers with a large volume of articles, the NEWNEWS command can
31          be expensive.
32
33       If the directory <configdirectory>/log/user  exists,  then  nntpd  will
34       create protocol telemetry logs for sessions authenticating as user. The
35       telemetry logs will be stored in the log/user directory with a filename
36       of the nntpd process-id.

OPTIONS

39       -C config-file
40              Use the specified configuration file config-file rather than the
41              default imapd.conf(5).
42
43       -U uses
44              The maximum number of times that the process should be used  for
45              new connections before shutting down.  The default is 250.
46
47       -T timeout
48              The  number of seconds that the process will wait for a new con‐
49              nection before shutting down.  Note that a  value  of  0  (zero)
50              will disable the timeout.  The default is 60.
51
52       -D     Run external debugger specified in debug_command.
53
54       -s     Serve  NNTP  over  SSL  (https).   All data to and from nntpd is
55              encrypted using the Secure Sockets Layer.
56
57       -r     Only allow NNTP reader commands.  Permitted clients will only be
58              allowed to read/post articles.
59
60       -f     Only allow NNTP feeder commands.  Permitted clients will only be
61              allowed to feed articles (no reading).
62
63       -p ssf Tell nntpd that an external  layer  exists.   An  SSF  (security
64              strength  factor)  of  1  means  an  integrity  protection layer
65              exists.  Any higher SSF implies some form of privacy protection.
