Hi Szymon,

I think the ntpd service is not a problem:

Subject: Re: [perfsonar-user] problems with perfSONAR 3.5.1 post-installation

Hello,

On the last days I have tried finish the installation of our pS but I had some problems.

First of all, I have tried install the perfsonar new version 4.0rc2 but I had problem with HD controller compatibility and I didn't getting install it.

To mitigate this, I have tried install the perfsonar version 3.5.1 but again I had some problems.

I have finished the steps from "http://docs.perfsonar.net/install_centos_netinstall.html" to perfsonar installation.

From "http://docs.perfsonar.net/install_config_first_time.html" I did follow "Your First Login" steps until "Accessing the Web Interface" and

I have tried access http://ps-bw.sdmz.rnp.br or http://200.143.243.4 but I didn't get access.

So, I couldn't finish the perfsonar installation because this issues. I attachment here some log files.

Moreover, I did some tests in command line using bwctl and owping to ESnet host and USP host that I attachment here, and I think the BW tests failed.

I'd like to know if someone could help me to try fix it?

Hi Gustavo,

About the test errors, can you check if ntpd is synchronising your clock? Use ntpq -p to verify if it is running and synchronising to some NTP servers.

Regards,
