# nntpd - Unix, Linux Command

# NAME

nntpd - NNTP server process

# SYNOPSIS

nntpd [ -C config-file ] [ -U uses ] [ -T timeout ] [ -D ]
[ -s ] [ -r ] [ -f ] [ -p ssf ]

# DESCRIPTION

Nntpd is a NNTP server. It accepts commands on its standard input and responds on its standard output. It MUST invoked by master(8) with those descriptors attached to a remote client connection.

Nntpd reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C. The optional newsprefix option specifies a prefix to be prepended to newsgroup names to make the corresponding IMAP mailbox names. The optional newspostuser option specifies the special userid to be used when contructing the To: header address for following up to articles when read via IMAP. The optional newspeer option specifies the fully qualified hostname of the upstream news server to which articles are fed. The optional allownewnews option enables the NNTP NEWNEWS command. NOTE: For servers with a large volume of articles, the NEWNEWS command can be expensive.

If the directory log/user exists under the directory specified in the configdirectory configuration option, then nntpd will create protocol telemetry logs for sessions authenticating as user. The telemetry logs will be stored in the log/user directory with a filename of the nntpd process-id.

# OPTIONS

-C config-file
