I posted this query a while ago but have not yet been able to resolve the issue...

I have a DNS server and client that can ping each other using ping6.  The following query works:

dig -6 test.com +notcp 

When I query TCP with IPv6 I get the following error:

root at test:/home/janderson/bind-9.6.1-P1 dig -6 test.com @bind6 +tcp
socket.c:4922: 22/Invalid argument
dig: isc_socket_connect: unexpected error

The query never leaves the client so the server never logs anything and I get the same result if I issue the dig command from the client or DNS server.

Config details follow

O/S => RH 5 64-bit
