Hi Szymon,

Thank you for your suggestion.

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,

What does "yum info python27-mod_wsgi" show?  If the repo is Internet2 then it's ok.

Loking at the error messages it could be that you have the wrong version of the above package. You need the version from the Internet2 repo. If you are also pointing at the SCL repos you may have gotten the version they provide. If that’s the case, you should disable the SCL repos (yum remove centos-release-scl) and try a "yum downgrade python27-mod_wsgi" or you may need to reinstall python27-mod_wsgi.

Best regards,
