perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi,

It gets read from the file /etc/perfsonar/toolkit/configdaemon.conf which should look like this: https://raw.githubusercontent.com/perfsonar/toolkit/master/etc/configdaemon.conf

If it differs you can try dropping the file I linked in place and changing the owner to perfsonar.

Thanks,

Andy

The code that trigs the error message is

 

    unless ($self->{ACCESS_CONTROL}->{file}->{$filename}->{write}) {

        $self->{LOGGER}->error("Couldn't write file $filename: write permission denied");

        die("Access denied");

    }

in the file “/usr/lib/perfsonar/lib/perfSONAR_PS/NPToolkit/ConfigManager/ConfigDaemon.pm”

 

I authenticated as the perfsonar web admin user.  The file is owned by user “perfsonar:perfsonar” while the httpd daemon is run as user “apache:apache”.  How does apache user modify the configuration file in web_admin?

I was able to configure tests on a server yesterday, it fails today.  How does the “ACCESS_CONTROL” work?

 

Thank you.

Subject: [perfsonar-user] perfsonar configuration error

 

Hi all,

 

I try to configure perfsonar using the web gui, I had problem saving the config.

 

Error: Couldn’t save configuration file.  The configdaemon.log has the following:

2018/09/10 12:20:33 (2043) ERROR> ConfigDaemon.pm:152 perfSONAR_PS::NPToolkit::ConfigManager::ConfigDaemon::writeFile - Couldn't write file /var/lib/perfsonar/toolkit/gui-tasks.conf: unknown file

 

This file exists and is owned by the user “perfsonar”, perfsonar admin user.

 

The host is running CentOS 7 with perfsonar 4.1.1

 

Thank you.
