bind 9 forwarders: use UDP or TCP?
I use forwarders for a subzone, but TCP 53 is blocked, So does forwarders really need TCP?
If forwaders use UDP, I can't get following scenario to work:
main zone is master, but subzone is forwad. Is it possible?
(On name sever itself, resolution of xx.stub.abc.com worked fine.)

Code:
 
#sub zone
zone "stub.abc.com" {
 type forward;
 forward only;
 forwarders { 1.1.1.1; };
};
 
#main zone
zone "abc.com" {
 type master;
 ...
};

NAME

       zcons - Zone console device driver

DESCRIPTION

       The  zcons character driver exports the console for system zones. The driver is comprised of two "sides:" a master side with which applica-
       tions in the global zone communicate, and a slave side, which receives I/O from the master side. The slave side is available in the  global
       zones.

       Applications must not depend on the location of /dev or /devices entries exported by zcons. Inside a zone, the zcons slave  side is fronted
       by /dev/console and other console-related  symbolic links, which are used by applications that expect to write to the system console.

       The zcons driver is Sun Private, and may change in future releases.

FILES

       /dev/zcons/<zonename>/masterconsole

	   Global zone master side console for zone <zonename>.

       /dev/zcons/<zonename>/slaveconsole

	   Global zone slave side console for zone <zonename>.

       /dev/zconsole

	   Non-global zone console (slave side).
