ixfr via tcp?

[Andreas Ihl]

hello,

is it possible to initialise an ixfr-transfer via tcp?

i want to use a ssh-tunnel for the transfer but AFAIK you cannot tunnel upd via ssh (without an proxy) and bind first try to initialise the transfer by udp. 

here is a part of my config:

// *** SLAVE-ZONES ***
zone "test" {
        type slave;
        masters port 9300 { 127.0.0.1; };
        transfer-source 127.0.0.1 port 9301 ;
        file "slave/ai.db";
        };
//end

maybe there is an option like 'masters tcp-port 9300 { 127.0.0.1; };' but i cannot find any informations and rfc1995 specify:
'a client should first make an IXFR query using UDP'.  


kind regards

andreas
