* plugin/transfer: only allow outgoing axfr over tcp Return refused when the query comes in over udp. No need to add a new test case as the current crop needed to be changed to use TCP. Fixes: #4450 Signed-off-by: Miek Gieben <miek@miek.nl> * transfer tests: this needs tcp as well Signed-off-by: Miek Gieben <miek@miek.nl>
