perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi Bill,

That issue looks different from the one one you reported back during the RC. The one from the RC was a validation error of the test parameters, the new one looks to be some type of connection error or possibly the URL formatting error that got fixed (though that usually resulted in a different error). While debugging some of this I did find a place in the meshconfig-agent where force_ipv4 was getting ignored for some tests so that might be part of it as well. I have RPMs with all these fixes but the infrastructure that builds and updates our yum repo is giving us fits. Once we get that corrected I should be able to get the new RPMs out and we can see what that fixes and if anything is leftover. 

Thanks,

Andy

I do have a test I set up a long time ago to bdw-uofm-fg.mrnet.mb.ca at 192.139.69.54, 2001:410:2000::4 that is defined with just the IPv4 number and that continues to work. However I’m not sure that bdw-uofm-fg.mrnet.mb.ca had an IPv6 address when I set up the test.

I see that 192.139.69.54 does not have a reverse DNS entry.

<target>
address 192.139.69.54
<override_parameters>
type bwctl
force_ipv4 1
</override_parameters>
description MRnet, Winnipeg, MB, CA
</target>

$ host 192.139.69.54
Host 54.69.139.192.in-addr.arpa. not found: 3(NXDOMAIN)


I added a new test for 131.243.246.66 ps-border1-pt.lbl.gov and that test has been added to /etc/perfsonar/meshconfig-agent-tasks.conf

<target>
address 131.243.246.66
<override_parameters>
type bwctl
force_ipv4 1
</override_parameters>
description test LBL
</target>

But the test results do not appear on the public dashboard.

131.243.246.66 does have a reverse DNS entry

host 131.243.246.66
66.246.243.131.in-addr.arpa domain name pointer ps-border1-pt.lbl.gov.
