OK, fixed this thanks to groups.google.com.
To restate the problem, on my server LIST ACTIVE group gives a wrong
message range. Example telnet session:
# telnet news.myisp.com 119
Trying 192.168.0.100...
Connected to news.myisp.com.
Escape character is '^]'.
200 news.myisp.com
mode reader
200 Sure!
list active comp.unix.solaris
215 Active file follows
comp.unix.solaris 0000358796 0000350838 y
.
group comp.unix.solaris
211 6088 351204 359007 comp.unix.solaris
quit
205 Exit articles 0, bytes 0, groups 1, posts 0, postbytes 0
Connection closed by foreign host.
Here, 'list active comp.unix.solaris' gives a wrong message range of
350838 to 358796, while the 'group' command gives the correct 351204
to 359007 range. Presumably a server misconfiguration.
Now, to prevent Gnus from using LIST ACTIVE and rather use GROUP
instead, one has to set nntp-server-list-active-group to nil (default
is 'try). Since this is a 'server slot variable', as Lars elsewhere
states, one should put it into the server definition given in either
gnus-select-method or gnus-secondary-select-methods in your .gnus
file.
E.g. my gnus-secondary-select-methods now contains the following entry
(nntp "news.myisp.com"
(nntp-server-list-active-group nil))
and this just works. On my other native servers, 'LIST ACTIVE' is
still used, and only for that specific server it's turned off.
One issue I observed though is that Gnus will use GROUP also on
foreign servers with this setting. Up to now, I had several gmane
groups just subscribed as foreign groups. So to still use 'LIST
ACTIVE' on them, I had to turn gmane native by putting it into my
gnus-secondary-select-methods. With this final tweak, everything's
fine now.
Thanks, Bruno.
