|4.2.6. Miscellaneous config data|
All the parameters in this section become macros in the file include/configdata.h. You should at least look through the parameters up to VERIFY_CANCELS. (If set to ``DO'', then innd will ignore cancel messages unless the From or Sender header match those of the original poster.) In general, however, you can leave this section pretty much alone until you have some experience running INN. Nevertheless, here are some comments on some of the more useful parameters. Innd can memory-map the active file if you set ACT_STYLE to ``MMAP''. On some systems, however, when a mapped file is updated its mtime is not updated. Apparently some versions of System V Release 4 have this problem. This causes problems for programs like nnmaster which look at the st_mtime field of the stat structure in order to determine if any new news has come in. (Nnmaster is part of the nn newsreading program.) The best work-around is probably an hourly cron job that touches the active file. There are a number of parameters that control the behavior of rnews. If you set RNEWS_SAVE_BAD to ``DO'' then articles that innd rejects for reasons like bad headers will be saved in the _PATH_BADNEWS directory; you will have to periodically scan this directory and clean it up. You can also control how rnews logs duplicates (those aren't saved regardless of the value of RNEWS_SAVE_BAD), logging them through syslog, to a file, or not. Note that if you set RNEWS_LOG_DUPS to ``FILE'', then you will want to change _PATH_RNEWS_DUP_LOG, which appears later in the file. If you receive news from several UUCP feeds, you might want to log duplicates so that you can cut down your phone bills by optimizing your feeds. The RNEWSPROGS parameter says whether or not to look in _PATH_NEWSPROGS for commands named on the incoming ``#!'' line of news batches. You probably want to set this to ``DO''. Make sure that the full pathname of rnews, _PATH_RNEWS, does not conflict with the directory where your unpackers are put, _PATH_NEWSPROGS. If IPADDR_LOG is set to ``DO'' then the news log will report the IP address of hosts that send articles, rather then what they put in the Path line. This can be useful if you run innd with the ``-a'' flag. (If you do this, you might want to pick up ``hf.tar.Z'' via anonymous FTP to ee.lbl.gov; it is a filter that turns IP addresses into host names.) The xxx_TIMEOUT parameters control various timers within INN; you might want to change some of these depending on your system load.
