secure bind a bit

[jayd]

in the normal configuration of ispconfig the system is vulnerable for this http://www.cert.org/incident_notes/IN-2000-04.html kind of attack.

I had installed ispconfig on a fresh ubuntu 5.10 Server install. So i can't say if this is Ubuntu or ispconfig vault. But solving is really easy.

So if you modified the named.conf.master (found in /root/ispconfig/isp/conf/) to the following, everthing is fine !

replace xxx.xxx.xxx.xxx with your puplic IP!

acl recurseallow { xxx.xxx.xxx.xxx; 127.0.0.1; };
options {
        pid-file "/var/run/bind/run/named.pid";
        directory "{BINDDIR}";
        auth-nxdomain no;
        allow-recursion { recurseallow; };
        /*
         * If there is a firewall between you and nameservers you want
         * to talk to, you might need to uncomment the query-source
         * directive below.  Previous versions of BIND always asked
         * questions using port 53, but BIND 8.1 uses an unprivileged
         * port by default.
         */
        // query-source address * port 53;
};

Maybe it has to be placed here
