Re: IPv6 DNS Queries
Check the following recent threads. Looks like you may have the same problem
I was having.
- Local address lookup
- Exim - DNS problem
- Woody IPv6 problem finally, really, solved
>From the last thread:
[snip]
Woody versions of some Debian packages, like telnet,
and, it seems, exim, *require* IPv6 addresses for your local
machines (including localhost!) in /etc/hosts, or they will call
your ISP to ask for them. And of course your ISP's nameservers
don't have them either. Specifying local lookup ("files") in
/etc/nsswitch.conf does not help.
So if your /etc/hosts is, for instance:
127.0.0.1 localhost
192.168.1.1 mars.my.home mars
192.168.1.2 jupiter.my.home jupiter
192.168.1.3 venus.my.home venus
Then at the end of the file you have to add
::FFFF:127.0.0.1 localhost
::FFFF:192.168.1.1 mars.my.home mars
::FFFF:192.168.1.2 jupiter.my.home jupiter
::FFFF:192.168.1.3 venus.my.home venus
The stuff already added to /etc/hosts by the Woody upgrade
process, like
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
etc., should remain where it is.

Hope this helps,
