perfSONAR User Q&A and Other Discussion

[Gerald Vogt <>]

Hi!

I have recently installed perfsonar-toolkit-4.2.3-1.el7.noarch on a new 
hardware with a minimal CentOS 7.

When I configure tests through the toolkit gui I get an 'Internal Server 
Error' and see errors in the apache error log:

regular_testing.cgi: Config::General: Cannot create hashref from 
<target> because there is, referer: 
https://perfsonar.example.com/toolkit/auth/admin/tests.cgi
regular_testing.cgi: already a scalar option 'target' with value 
'psmp-gn-bw-01-fra-de.geant.net', referer: 
https://perfsonar.example.com/toolkit/auth/admin/tests.cgi
regular_testing.cgi line 38., referer: 
https://perfsonar.example.com/toolkit/auth/admin/tests.cgi

It seems to be a problem if there are some hosts having ip4 and ipv6 and 
some not. If I look at /var/lib/perfsonar/toolkit/gui-tasks.conf I see a 
block like this:

<test>
    <parameters>
        tool   iperf3
        test_ipv4_ipv6   1
        type   bwctl
        duration   20
        packet_tos_bits   0
        window_size   0
    </parameters>
    target   psmp-gn-bw-01-fra-de.geant.net
    <target>
        address   lond-owamp.es.net
        <override_parameters>
            type   bwctl
            force_ipv4   1
        </override_parameters>
    </target>
    description   Throughput
    <schedule>
        type   regular_intervals
        interval   21600
    </schedule>
</test>

If the target   psmp-gn-bw-01-fra-de.geant.net statement is above the 
following <target> block it fails. If it as after the block it works.

Bug?

Thanks,

Gerald
