Hi Charley,

 

Could you please clarify:

-          Which bundle do you use?

 

I have two builds – one based on the 4.X ISO (Centos 7) and another based on an upgrade 3.5 build (Centos 6.9) both have the same problem.

 

-          Do you have IPv4 tests working?

 

Yes –

 

-          How did you configure IPv6 tests (where)?

 

GUI – add a host with an IPv6 name and check the [] IPv6 checkbox and un-check the v4 checkbox.

  I have also directly used the IPv6 address.

 

-          Did you run command line tests for verification? Do you have results  you can share?

 

Can you send me an example – I have only run a command link ping test.

 

-          Any log events, that you find related and suspicious ?

 

Nothing that I noticed – but if there are particular places to look, please let me know.

 

 

Regards,

Ivan Garnizov

Hello All,

 

I am unable to get IPv6 tests to work.

 

I can ping a remote IPv6 node:

 

ping6 sdsc-pt1-v6.es.net
PING sdsc-pt1-v6.es.net(sdsc-pt1-v6.es.net) 56 data bytes
64 bytes from sdsc-pt1-v6.es.net: icmp_seq=1 ttl=48 time=107 ms
64 bytes from sdsc-pt1-v6.es.net: icmp_seq=2 ttl=48 time=106 ms
64 bytes from sdsc-pt1-v6.es.net: icmp_seq=3 ttl=48 time=105 ms
64 bytes from sdsc-pt1-v6.es.net: icmp_seq=4 ttl=48 time=104 ms

rtt min/avg/max/mdev = 104.495/105.886/107.681/1.283 ms

name services are resolving properly

[root@ps-node-c pscheduler]# nslookup -type=aaaa sdsc-pt1-v6.es.net
Server:         192.168.202.5
Address:        192.168.202.5#53

Non-authoritative answer:
sdsc-pt1-v6.es.net      has AAAA address 2001:400:1101:1150::3

 

I have added an IPv6 host to a PS4 node and confirmed that it is set for IPv6

 

I see no tests with the hostname (sdsc-pt1-v6) in the pscheduler logs and no tests with --ip-version=6 in the logs either.

 

I do have a private v4 address, but have a public V6 address that is exposed for icmpv6.

 

Anyone have any suggestions?

 

Charley
