    Default [SOLVED] Installation Ubuntu 8.04 no DMZ

    Hi there,

    I want to install and evaluate the free edition of zimbra and ordered a root ubuntu 8.04 server from a german hoster.

    I've read about the DMZ / Split-DNS stuff in all tutorials, but I am not sure if I have such setup there. I belive my internal IP is also my external IP and my root server is connected to the outside word exactly with the same ip. (*edit*: I am using the Wiki installation guide)

    The interface I found was this (except for the XXX):

    Code:
    iface eth0 inet static
      address   78.46.XXX.162
      broadcast 78.46.XXX.191
      netmask   255.255.255.224
      gateway   78.46.XXX.161
    I can ping my server with this ip from the outsite and locally. So the ip was static already. I also installed the bind9 and set it up the way as described in the install guide. I moved the defined nameservers to the forwarders definition and set as nameserver my own ip.

    Code:
    ; BIND data file for example.de
    $TTL    604800
    @       IN      SOA     mail.example.de. admin.example.de. (
                             090225         ; Serial
                             604800         ; Refresh
                              86400         ; Retry
                            2419200         ; Expire
                             604800 )       ; Negative Cache TTL
    ;
    @       IN      NS      mail
            IN      MX      10 mail
            IN      A       78.46.XXX.162
    mail    IN      A       78.46.XXX.162
    I hope that makes sence. My nslookup therefor eis still the ip I got from the hoster.

    Another problem for me is that I got the server with just an IP and a dummy hostname like:

    Code:
    Ubuntu-804-hardy-LTS-32-minimal
    I think thats the default. I changed it to mail in the /etc/hostname file because I want to use zimbra on mail.example.de

    my hostfile looks lik this:

    Code:
    ### Hetzner Online AG installimage
    # nameserver config
    # IPv4
    127.0.0.1 localhost
    78.46.XXX.162  Ubuntu-804-hardy-LTS-32-minimal
    10.3.2.244 mail.tractor-equip.net mail
    78.46.XXX.162 mail.example.de mail
    #
    # IPv6
    ::1 ip6-localhost ip6-loopback
    fe00::0 ip6-localnet
    ff00::0 ip6-mcastprefix
    ff02::1 ip6-allnodes
    ff02::2 ip6-allrouters
    ff02::3 ip6-allhosts
    I'm a linux user I know how to use bash and tweak here and ther efiles with the tools given me, but I am not much in the internals.

    When I start the install of zimbra it stops at the point where it seems to check for the hostname with:

    Code:
      ERROR: Installation can not proceeed.  Please fix your /etc/hosts file
      to contain:
    
        
    
      Where  is the ip address of the host,
       is the FULLY QUALIFIED host name, and
       is the (optional) hostname-only portion
    The output of hostname --fqdn is:

    Code:
    mail.tractor-equip.net
    I *think* thats according to the plan, but I am not sure. For domains I am using an domain register service where I can set up dns stuff for my domains, so "example.de" is currectly pointing to that server.

    I have read in another thread that the guy has just commented out the line where the hostname check is, but I am not that experienced in linux that I know that everything is correct.

    Logfiles seem to be empty at this pioint.

    Any hint how to go further in the installation are apreciated.

    Have you read my text at all? I am doing it with this installation guide, but I am stuck. :/

    (the spamprotection here is wired. When I edit my initial post it gets invisible again ...)

    I rephrase my question:

    What is the zimbra installer expecting at the point, when it checks the hostname? What word has to match what? I need to know so the installer will continue. Hopefully.

    I fixt it by using another tutorial where I found these steps:

    Code:
    echo mail.example.com > /etc/hostname
    and

    Code:
    hostname
    hostname -f
    Both should show mail.example.com.

    Which did and the installation went through.
