DNS Aliases on Debian 3
I'm running Debian 3 and am trying to set up the whole caboodle (mail, ftp, web, dns) on one server. I have a domain name (diablog.co.uk) which is on external domain name servers. I have the external DNSes set up so that certain subdomains (eg me.diablog.co.uk) are pointed at my server. However, my router can't cope with using these external DNSes since when I am trying to get to them from the inside. Therefore, I am using my server as a DNS server from inside my network.
My problem is that I can't create an alias for my server.
I tried doing it manually, and then installed webmin to help. From webmin, my "records file" looks like this:
$TTL 43200
diablog.co.uk. IN SOA rover.diablog.co.uk. 2003102514 (
6
15
14D
12H
)
@ IN MX 5 192.168.7.100.
@ IN NS 192.168.7.100.
diablog.co.uk. IN A 192.168.7.100
me.diablog.co.uk. IN CNAME rover.diablog.co.uk.
Dunno if it's any use.

No, I need them all running on the same IP. I know that this is possible in windows using aliases, so I'm sure that it must be possible when using BIND
So have you made the external name server to give you namespace of
me.diablog.co.uk
Then for you to add
machine1.me.dablog.co.uk
me.diablog.co.uk
Then for you to add
machine1.me.dablog.co.uk
Or is your problem that you want
me.diablog.co.uk look to be 123.123.123.123 from the outside and 192.168.1.3 from the inside.
me.diablog.co.uk look to be 123.123.123.123 from the outside and 192.168.1.3 from the inside.

The second. From the outside the router will pass packets to the server which will then deal with it (i.e. Apache and virtual domains), but on the inside it goes straight to the server.
you have a CNAME that points to rover.diablog.co.uk, but no actual entry for "rover" ?
Not sure if this is because you have chopped some of the file out or what ?
Rather than using a CNAME, try just putting in the actual IP address (192.168.1.3) and see if this works.

Is that necessary, since my PC can already see rover?
Anyway, i did what you suggested, but this didn't work. For the record, my new file lnow looks like this:
$TTL 43200
diablog.co.uk. IN SOA rover.diablog.co.uk. 2003102514 (
6
15

diablog.co.uk. IN A 192.168.7.100
me.diablog.co.uk. IN CNAME 192.168.7.100

That web page is what I want, but I'm unsure how I should go about it. I've changed the config as above, so it now reads:
$TTL 43200
diablog.co.uk. IN SOA rover.diablog.co.uk. 2003102514 (
7
15
14D
12H
)
@ IN MX 5 192.168.7.100.
@ IN NS rover
rover.diablog.co.uk. IN A 192.168.7.100
me IN A 192.168.7.100

me IN A 192.168.7.100

Ta muchly HalldorG. I got a bit confused last night with what you said, and then read it tonight and it all made sense. Many thanks.
listen-on { 192.168.1.2; };
Therefore you could be running 2 instances of bind
or have different profile depending
on where the query is coming from.
