- nntp
-
- The 'nntp' commands control the operation of the Network News
- Transfer Protocol (NNTP). The nntp features are defined at
- compile-time. Two NNTP modules are available, "NNTP" which is an
- NNTP client only, that stores news in a mailbox-compatible form,
- and another, "NNTPS" which is a both an NNTP client and server,
- that stores news articles in a form inaccessible to mailbox users.
-
- We first describe the "NNTP" nntp client features:
-
- nntp addserver <nntpserver_host> <interval> [<range>] [<groups>]
- Add an NNTP news server to query every <interval> seconds for new
- articles in the specified <groups>.
-
- <range> specifies the time-of-day limits when the queries will be
- made, in the form hh:mm-hh:mm where start time precedes end time.
-
- Multiple 'nntp addserver' commands may be used to concatenate
- groups (up to a maximum of 512 bytes).
-
- Example: nntp add w5ddl.ampr.org 3600 18:00-06:00
-
-
- nntp directory [ <News_spool_dir> [News_control_dir> ]
- Display or set the spool directory for spooling news articles.
- Default is /spool/mail. Optionally set a new control directory.
- The default control dir is /spool/news.
-
-
- nntp directory old=new
- Establish a newsgroup name mapping, so that a newsgroup name
- beginning with <old> is changed to one beginning with <new>,
- which may be a null string. To delete a mapping, use <old>==.
- The mapping scan continues until the list is exhausted, in the
- same order the nntp dir commands were specified.
-
- Example: nntp dir rec.radio.=
- nntp dir amateur.=
- nntp dir shortwave=swl
- nntp dir equipment=eq
-
- will map rec.radio.amateur.policy to policy, rec.radio.swap
- to swap, rec.radio.shortwave to swl, and
- rec.radio.amateur.equipment to eq.
-
-
- nntp dropserver <nntpserver_host>
- Drop the specified NNTP server from the list of servers to contact.
-
-
- nntp firstpoll [<#days>] Default: 5
- Sets or shows the number of days of old news that is requested
- in the initial poll to a new server.
-
-
- nntp groups <group> [<group> ...] Default: All groups
- Display or set the currently set USEnet newsgroup(s). The group
- names are separated by spaces or commas. The '*' and '!'
- metacharacters (meaning 'all' and 'not' respectively) are
- supported.
-
-
- nntp kick <nntpserver_host>
- Kick the local NNTP client to get in touch with the named server.
-
-
- nntp listservers
- List the currently defined servers.
-
-
- nntp lzw <ON | off>
- Turn on or off attempts to request LZW compression be used by
- the server when sending articles.
-
-
- nntp trace <level> Default: 1
- Sets or shows the current trace level for NNTP traffic.
-
- Level
- 0: No tracing.
- 1: Display serious errors only
- 2: Display serious and transient errors
- 3: Display serious and transient errors, plus session progress
- 4: Display serious and transient errors, session progress and
- actual received articles
- 5: Display errors.
-
-
- nntp quiet <yes | NO> Default: no
- Sets or shows the current arrival-notification setting for NNTP
- traffic. The notification will include a BEL character if
- "smtp quiet no" is in effect.
-
-
-
-
-
-
- We now describe the "NNTPS" client/server commands. Remember
- that the 'start nntp' command must be used to allow the nntp server
- to accept connects from other nntp clients.
-
-
- nntp active
- Displays the active file, which shows configured newsgroups.
- See 'nntp create'.
-
-
- nntp access [on | OFF]
- Displays or sets whether access permissions are enforced. When
- enabled, the file /spool/news/access is scanned to determine the
- access permissions for a client host. Each line of this file has
- fields of the form: host:permissions:
- where host is explicit hostname (FQDN) or starname, eg, *.aara.org
- and permissions are a string of chars: R => read, P => post,
- none=>deny access. When access is turned on, hosts not mentioned
- are DENIED nntp access.
-
-
- nntp add <nntpserver_host> <interval> [<range>] [<groups>]
- Add an NNTP news server to query every <interval> seconds for new
- articles in the specified <groups>. If no <groups> are specified,
- all groups found in /spool/news/active are checked.
-
- <range> specifies the time-of-day limits when the queries will be
- made, in the form hh:mm-hh:mm where start time precedes end time.
-
- Multiple 'nntp add' commands may be used to concatenate groups
- (up to a maximum of 512 bytes).
-
- Example: nntp add news.usl.edu 3600 usl.test,rec.radio.swap
-
-
- nntp create <news.group.name> [y|n]
- Updates the /spool/news/active file, which must have an entry
- for each news group you wish to receive. Choose y to permit
- posting to this group, or n to deny posting. y is assumed if
- nothing is specified. The /spool/news/pointer file is also
- updated with the path to the directory which will contain the
- articles. Articles will be stored as separate files, named
- by an integer corresponding to their arrival order.
-
-
- nntp drop <nntpserver_host>
- Drop the specified NNTP server from the list of servers to contact.
-
-
- nntp dump <newsgroup> [<areaname>]
- Dump all the news articles in <newsgroup> to the Jnos area
- called <areaname>. This would allow mailbox users to read news,
- but no provisions are made to dump just new articles. If
- <areaname> is omitted, then <newsgroup> is used as the area name.
-
-
- nntp firstpoll [<#days>] Default: 5
- Sets or shows the number of days of old news that is requested
- in the initial poll to a new server.
-
-
- nntp ihave [<val>] Default: 0
- Set or display the IHAVE nntp-protocol behaviour.
- 0 => IHAVE disabled (default)
- 1 => IHAVE reports only for newsgroups associated with serverhost
- 2 => IHAVE reports for all newsgroups
-
- The IHAVE protocol tells the server the message-ids of articles
- stored here; it is used to forward articles off this system.
-
-
- nntp kick <nntpserver_host>
- Kick the local NNTP client to get in touch with the named server.
-
-
- nntp list
- List the currently defined servers.
-
-
- nntp lzw <ON | off>
- Turn on or off attempts to request LZW compression be used by
- the server when sending articles.
-
-
- nntp post
- Posts to a local newsgroup. A session is created, and the console
- user is queried for UserName (unless established by a prior 'nntp
- profile' command), Newsgroup, Subject, and message body. While
- entering the msg, a line consisting of ".u" or ".r" will then
- prompt for a file name, which is inserted into the article being
- built. "/EX", "***END" or "." will end the article when found alone
- on a line. When the message body is terminated, the prompt
- [Send, Abort, Exit, List]
- is displayed. Enter the first letter of the desired choice.
- Note that Exit quits the post subcommand, while Abort (or Send)
- allows you to post another article.
-
-
- nntp profile {fullname|host|organization|reply|sig|user} string_value
- Profile establishes values for the header fields of posts
- originating here. Options include:
-
- sig path_to_signature_file
- host FQDN Defaults to our 'hostname'
- fullname "First Mi. Lastname"
- organ "organization name desired"
- user "user name"
- reply reply-to-address
-
-
- nntp read <newsgroup> [<article_number>]
- Reads the local <newsgroup>, beginning with the first unread
- article unless <article_number> is also provided. A session is
- created for displaying the articles. After each article, a
- prompt "Read next/previous? (n/p/q) " allows the console user to
- easily progress through the articles.
-
-
- nntp quiet [<val>] Default: 0
- Dispays or sets the value if the quiet behaviour flag. Nntp will
- display a message and/or beep when a new article arrives:
- 0 => beep only (default)
- 1 => beep and display msg
- 2 => no msg or beep
-
-
-
- NOTES:
- 1. See the 'expire' command for information on removing old articles.
- 2. The TO: addresses, when present, are stripped from article headers
- by the NNTP client. This was done to prevent loops should the
- area be forwarded to another Jnos system, since the TO: address
- would cause the msg to be routed back to the mail-to-news daemon.
- If you want to forward an area, give the TO: address on the line
- in forward.bbs that lists the area. Example: rec.radio.swl all@swl
- 3. The NNTPS software includes a mail-to-news feature, such that email
- with a To: address that begins with "!" is passed to the NNTPS
- module. The remainder of the To: address is interpreted as a
- newsgroup name, with the name truncated at the first occurence of
- one of "%@.,/", and with "!" translated to ".". An alias is usually
- used to provide this special name. For example, to route all ALLUS
- bulletins to both the allus area, and the ampr.allus newsgroup,
- use the alias: allus allus !ampr!allus
