Bind9 DNS on Ubuntu 10.10

Hi there, I've had Bind9 running on a Ubuntu 10.10 server for the past few weeks, and today I went to use the " match-clients " like follows:

Code:

acl internals {
    10.0.0.0/24;
};

view "internal" {
    match-clients { internals; };
    zone "domain.com" {
        type master;
        file "/etc/bind/zones/domain.com.db";
    };
};

When I use the " Match-clients " I'm unable to start the service. " could not access pid file ". If I then remove the " match-clients " section, everything works normally. I've looked around quite a bit, and haven't found out why it's doing this.

Any help would be appreciated! So thank you in advance

Josh
