Well, using them doesn't bother me, maybe one day i'll regret... Where can
I find an explanation of your "hate" of dynamic IDs ?

Hope so ;-)

Ok.

Well, that's funny, because I just noticed that while this happens _only_
on this particular machine, I get the same behaviour both on the host and
in a vserver of that host !

Maybe a shorewall bug/misconfiguration ? Mmmm... I do not think it's
VS-related, because other hosts do not behave like this, but rather
Samba or Mandriva related.

Ok, now, (for Enrico ?), one more bug :

 * When stopping a vserver, in addition to the strange message cited in
my previous mail, I noticed that the corresponding IP alias in still up
and running, answering to pings, etc... Is it a right behaviour ?
