DNS extended allow-recursion with wrapper?

[ThomasR]

Hi,

Plesk allows only 3 DNS recursion modes:

• Allow for all requests
• Allow for local requests only
• Deny

Behind the scene setting this option will result in a configuration made in the C:\Program Files (x86)\Parallels\Plesk\dns\etc\named.user.conf (or /var/named/chroot/etc/named.conf in Plesk for Linux), i.e.:

options{
allow-recursion    {localnets; };
listen-on-v6    {any; };
version none;
};

Since we need more flexibility (allowing DNS recursion from both localhost/localnets AND some specific external IP addresses), we are using a custom wrapper for the dnsmng tool in Plesk for Linux (/usr/local/psa/admin/sbin/dnsmng) which uses sed to insert some additional lines:

#!/bin/bash

/usr/local/psa/admin/sbin/dnsmng.orig "$@"
EXITSTATUS=$?

allow=`sed ':a;N;$!ba;s/\n/; \\\\\n\t\t/g' /etc/named.conf.allow.recursion 2>/dev/null`

sed -i '/\/\/ Start custom lines added by the wrapper/,/\/\/ End custom lines added by the wrapper/ d' /var/named/chroot/etc/named.conf

sed -i~ "/^[[:space:]]*allow-recursion {/{a \
\\\t\t// Start custom lines added by the wrapper: \
\n\t\t${allow}; \
\n\t\t// End custom lines added by the wrapper
}" /var/named/chroot/etc/named.conf >/dev/null 2>&1

/etc/init.d/named reload >/dev/null 2>&1

exit $EXITSTATUS

This works fine on Plesk for Linux. We now are looking for a similar solution on Plesk 12 for Windows. What is the best way to achieve this?
