perfSONAR 4.0.2 is out. The system as a whole is still remarkably wedded to IPv4. Dual stack is preferred over IPv6 only. It’s tough luck if you succeed 100 % with the latter. CentOS/anaconda supports IPv6 RDNSS when configuring the DNS settings. Now, if only Cisco IOS XE would allow me to enter a domain name while configuring RDNSS. The country of Norway is (again?) a valid selection in the perfSONAR web UI. Communities disappears when you edit system information unless you also reenter your communities. Test results are only shown in the web UI when you access the node by its IPv4 address. Only IPv4 results are shown in the web UI. I’m still looking for an IPv4 block to assign to my future perfSONAR nodes. I firmly believe complete independence of IPv4 is a noble goal for perfSONAR 5.
