You can't do tht if the name teiko.com has any other resource records:
like NS records or a SOA record for example.

Correct. A name can only exist as a CNAME if it doesn't exist as any
other record type. Well for Secure DNS, the name can have a SIG and
NXT record as well as the CNAME.

This is the right thing to do when it comes to setting up the zone
file. I presume you're trying to arrange that a lookup of teiko.com
returns some pointer to your web site. ie the A record above contains
the address of your web server.
You are doing something wrong. You're running BIND8.1.1. It's an old
version with known security holes. Upgrade to 8.2.3. And take a look
at:
