### 3. Configuration of DTC

#### 3.1 Access to configuration panel

Browse to the address you have configured during install phase (this URL was printed at end of the install script). Click on the topright icon to access to the main configuration panel.

#### 3.2 General configuration

- Demo version: let this radio button to 'no' or files and directory will not be created and tables will be emptied at each visits.
- Use javascript : Dome dangerous actions are confirmed by some javascript code. This tells not to use it, so it works with browsers that do not understand javascript.
- Use SSL : If this option is activated, the access to the DTC panel (admin and client (on this example dtc.domaine.com)) will occur using https instead of http. DTC will use OpenSSL keys generated by default in /etc/apache/ssl. Issue the following commands to generate those cert files:

    mkdir -p /etc/apache/ssl; cd /etc/apache/ssl
    [quoting apache-ssl.org]
    Step 1 - create the key and request:
      openssl req -new > new.cert.csr
    Step 2 - remove the passphrase from the key (optional):
      openssl rsa -in privkey.pem -out new.cert.key
    Step 3 - convert request into signed cert:
       openssl x509 -in new.cert.csr -out new.cert.cert -req -signkey new.cert.key -
    days 365
    [/quoting apache-ssl.org]

- Generate all apache vhosts on local network ip (NAT): activate this option if your server is behind a router that does NAT (Network Adress Translation).
- Local network area ip address of the vhosts using NAT: this options is to be specified if you have activate the one before. It's the IP address of the server on the LAN, and it will be used for apache's vhosts (named.conf zone files will continue to use external IP).
- Use multiple IP: in that example, the option have been set because of the use of NAT. - Main side IP: Note that you can use IP that the server does not have (in the case you only want to use them for named default conf for example).
- Host IP addresses: list here the different IP addresses that you'd like to see in the administrator interface. You must specify at least the primary IP address.
- Full hostname of the DTC admin panel: This tells what subdomain will be used to have Alias to /usr/share/dtc/admin and client folder. Be careful, this subdomain MUST exist in DTC configuration (the domain must be owned by one of your admins and the subdomain must exists with ip address to default).

#### 3.3 Configuration of the bind zones

This part of the configuration tells how the name zone files will be generated. The following example zonefile corresponds to the snapshot. Values between [] are the one that can be configured using this HTML form. Those are default values, that can be overridden by subdomain, NS or MX configuration for each domains.

    $TTL 7200
    @               IN      SOA     [ns1.example.com]. webmaster.example.com. (
    						2003092022; serial
                            1H ; refresh
                            60M ; retry
                            1W ; expire
                            24H ; default_ttl
                            )
    @	IN	NS	[ns1.example.com].
    @	IN	NS	[ns2.example.com].

    @	IN	MX	5	[mx.example.com].

    	IN	A	1.2.3.4
    pop	IN	A	1.2.3.4
    smtp	IN	A	1.2.3.4
    ftp	IN	A	1.2.3.4
    dtc	IN	A	1.2.3.4
    mx	IN	A	1.2.3.4
    ns1	IN	A	1.2.3.4
    ns2	IN	A	1.2.3.5
    www	IN	A	1.2.3.4

#### 3.4 Configuration of paths

Just leave it like that. It's only in the case you want to use more that one DTC interface.
