Re: [leafnode-list] Groups Not Being Removed
Here's the new section that is to become part of fetchnews(8) in
leafnode-2, feel free to ask, comment, ...
Note the @SPOOLDIR@ will be replaced automatically by ./cnofigure.
EXPIRY OF NEWSGROUPS
fetchnews(8) will drop newsgroup subscriptions after a
certain amount of time a particular "interesting" group
has not been read, unless run with the -n option.
Leafnode(8) will track for each group 1. when the last
posting has been downloaded from the upstream (.last.post
ing), 2. when an article in the group or the group
overview data has been requested by a client. The former
is marked in the ctime of the .last.posting file in the
group directory (@SPOOLDIR@/group/name/.last.posting for
the group group.name), the latter in the ctime of the
group.name file below @SPOOLDIR@/interesting.groups. When
the ctime difference between timeout_long, the group is
expired from interesting.groups. Use "ls -lc" or "ls -ltc"
or the tools/lsmac.pl utility to view the ctime(s) of a
particular directory or file or set of files.
For a newly subscribed group that has not been read more
than once, the interesting.group/group.name's ctime will
match its mtime. In this case, timeout_short applies
instead of timeout_long.
Dormant groups do not expire.
Note that this time mechanism does not recover when your
system clock is changed, so make sure your system clock is
right. A few minutes off don't matter practially, and day
light savings time is invisible to leafnode.
It is a good idea to run some NTP software, for instance,
"ntpd" or "chrony", against your ISP's NTP server, when
you've got a permanent internet connection, or to run
"ntpd -g -q -x" or "ntpdate" right after your dialup con
nection goes online. Chrony and Ntpd are third-party pack
ages that do not ship with leafnode and the documentation
of which are beyond the scope of this manual.
