Re: can bind keep best routes ?
JY:
If you run named (bind) on your 486, it will cache DNS responses.
The first time you look up wanadoo.fr, for example, named will go
through the root nameservers to find it, but subsequent lookups of
the same name will be much faster, because the 486 will use its
local copy. Your idea that you want to run a local nameserver in
order to speed up name resolution is correct. I don't think this setup
is what is causing your e-mail problems. It would help if you provided
more details about that problem (error logs from /var/log/exim/mainlog,
e.g.)
caveat = "beware", or "things to be wary of"
caveat emptor = "Let the buyer beware."
Some caveats about /etc/hosts: you may need to make some
changes to /etc/resolv.conf; it could cause problems if names or
addresses change; etc.

Yes, I meant IP address.

I'd like it to be automatic, is it possible ?

Sorry, I didn'd caught the meaning.

Yeah, in fact the problem is not so easy - i've got a little network: a 486 as a
router and a PII station.
I'm on the cable, and I need to declare the 2 DNS of my provider first, because
my identification is made by these DNS; for mailing, if I just declare the 486
as DNS, the smtp of the provider refuse to re-mail!
So I'd like to use the provider's DNS for the mail, and mine for the rest
(mine's faster!!); AND, if it is possible, keep a table of the most used IP
adresses, in order to gain time.
I hope I've not be too confused in my explanation.
Thanks in advance

JY
