- LLLLeeeeaaaaffffnnnnooooddddeeee is a USENET package intended for small sites, where
- there are few users and little disk space, but where a large
- number of groups is desired.
-
- The design of lllleeeeaaaaffffnnnnooooddddeeee is intended to self-repair after
- problems, and to require no manual maintenance.
-
- FFFFeeeettttcccchhhh is the program which submits and retrieves new
- articles to or from the upstream NNTP server.
-

- OOOOPPPPTTTTIIIIOOOONNNNSSSS
- -_v Be verbose. A maximum of four -_v can be used (the more
- v, the more verbose):
-
- -_v Warn about non-critical errors.
-
- -_v_v Be verbose whenever a group command occurs.
-
- -_v_v_v Be verbose whenever an article command occurs.
-
- -_v_v_v_v
- For debugging purposes. Don't expect the additional
- output to make sense.
-
- -_x _n_u_m_b_e_r
- Go _n_u_m_b_e_r articles back and try to re-fetch what's
- missing. Chiefly used for debugging purposes.
-
- -_l Don't use supplementary servers ( -_l is supposed to
- mean "local"). This does speed up the operation quite a
- bit.
-
- -_n Don't unlink files in the _i_n_t_e_r_e_s_t_i_n_g._g_r_o_u_p_s directory.
- This avoids automatic unsubscription of newsgroups.
-
- -_f Force rereading of whole active file from all upstream
- servers. This is usually occurring only very
- infrequently because it takes a long time.
-
- -_P Only post articles that have accumulated in the
- _o_u_t._g_o_i_n_g directory but do not fetch articles from
- upstream servers.

- See lllleeeeaaaaffffnnnnooooddddeeee(8) for the list of files affected, and for
- information on configuring ffffeeeettttcccchhhh....
-
-
- AAAALLLLGGGGOOOORRRRIIIITTTTHHHHMMMM
- Here is a brief description of what ffffeeeettttcccchhhh does.
-
- First, after connecting to the upstream NNTP server, all
- articles in /_v_a_r/_s_p_o_o_l/_n_e_w_s/_o_u_t._g_o_i_n_g are posted using POST.
- If a posting fails, that article is moved to
- /_v_a_r/_s_p_o_o_l/_n_e_w_s/_f_a_i_l_e_d._p_o_s_t_i_n_g_s which an administrator has
- to clean up once in a while. Moving a file back to
- /_v_a_r/_s_p_o_o_l/_n_e_w_s/_o_u_t._g_o_i_n_g is sufficient to resubmit it.
-
- Second, the upstream server's list of newsgroups (obtained
- using LIST ACTIVE and LIST NEWSGROUPS) is merged into
- lllleeeeaaaaffffnnnnooooddddeeee's (this step is most often optimized away).
-
- Third, ffffeeeettttcccchhhh iterates over the list of newsgroups,
- performing a GROUP, an XHDR Message-ID and a number of HEAD
- and BODY commands for each group which has been read
- recently.
-
-
- NNNNOOOOTTTTEEEESSSS
- FFFFeeeettttcccchhhh does not use NEWNEWS or XOVER. NEWNEWS is not used
- because it is often very expensive, XOVER is not used
- because the information it obtains is also present in the
- article headers.
-
- After some experiments, I decided that it was better to
- fetch all the articles in a group than to optimize away
- some; users would complain too loudly when the optmizer
- guessed wrongly. LLLLeeeeaaaaffffnnnnooooddddeeee is not intended to be all things
- to all men, and I have sacrificed the ability to read news
- from two upstream servers. (There is some support for it,
- but it is incomplete and undocumented at the time of
- writing.)
-
- FFFFeeeettttcccchhhh happens to support local groups, even though the rest
- of lllleeeeaaaaffffnnnnooooddddeeee doesn't.
-
- The only way to control what newsgroups are accessible to
- local users is to control what the upstream server lets
- ffffeeeettttcccchhhh read, and that will not keep out all crossposts
- (endemic in e.g. the alt.sex groups). If your site is big
- enough that you need to control newsgroup access, consider
- using a news server which is designed for a big site.
-
- FFFFeeeettttcccchhhh sets its real and effective uid to "news", because
- almost all of the problems I have had with lllleeeeaaaaffffnnnnooooddddeeee are due

- to files which aren't writable for user news.
-
-
- BBBBUUUUGGGGSSSS
- FFFFeeeettttcccchhhh ignores the "Supersedes" and "Also-Cancel" headers.
- This needs to be fixed, or news.answers will suffer.
-
- Never deletes a group from the list of active newgroups.
