Comment 3 Adam Tkac 2008-01-11 10:09:28 UTC
I've started testing (by hand, of course) of problem 1 (Returning of answer) and
found some strange configuration mistakes.
Machine 1: IPV6tester, FreeBSD,
Machine 2: IPv6testee, RHEL 5.1,

First, network configuration (from
should have this topology:

Machine 1: IPv6 addr 3ffe:501:ffff:101::20
                      router 3ffe:501:ffff:100::1
Machine 2: IPv6 addr 3ffe:501:ffff:100:XXXX

Machine 2 has correct configuration (ifconfig eth0 says inet6
3ffe:501:ffff:100:21a:a0ff:febd:5d1/64) but I'm pretty unsure about machine 1.
It doesn't have any IPv6 address assigned. Also I'm not able ping6 router.
Please tell me if network configuration is set as expected. Looks it isn't for me.

Comment 5 Zhiyong Wu 2008-01-14 10:30:28 UTC
Machine 1: IPV6tester, FreeBSD,
Machine 2: IPv6testee, RHEL 5.1,

(1) the two interfaces is not used for testing DNSv6, but used for your remotely 


(2) the two interfaces used for testing DNSv6 are rl0( freebsd6.2)
and eth0 ( rhel5.1)

(3) the topology above is a logical topology, TAHI test suites will create it 


note that the network configuration you saw last time is used for IPv6 DNS test.

now, you can login IPV6tester by ssh and IPV6testee by ssh, and look at the ipv6 DNS test environment. 

Comment 6 Zhiyong Wu 2008-01-14 10:40:47 UTC
the two interfaces used for ipv6 DNS test are:

Machine 1: IPV6tester, FreeBSD, rl0 ,
Machine 2: IPv6testee, RHEL 5.1, eth0,
