i installed bind-chroot ,but the file /etc/named.conf always is options { pid-file "/var/run/named/named.pid"; directory "/var/named"; auth-nxdomain no; /* * 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; }; the red part. even i change that to /var/named/chroot .... and copied /var/named/name.* pr* /var/named/chroot/var/named/ when restart the named.conf change to orignal. set the directory to /var/named and the ispconfig dns manager auto create the pri-file in the directory /var/named what should i do? i am just wondering . the same install sequence ,why this time the bind-chroot can't work fine.
