perfSONAR User Q&A and Other Discussion

[Gustavo Neves Dias <>]

Hi Szymon and All,

Now, fortunately, we solved the MTU problem and our perfSONAR server is up again.

https://ps-bw.sdmz.rnp.br/toolkit/

Thanks for your tips.

Best regards.

Gustavo Dias.

Hi Szymon,

Recently, I discover that our connection have a MTU problem (less than 1500 bytes) and I already contact our network engineering to fix it.

Furthermore, I installed SSL certificate in the server and "like a miracle" the web interface is accessible by https://ps-bw.sdmz.rnp.br/toolkit/.

So, the owamp (latency) tests are OKay. But, the bwctl (bandwidth) tests are still with problem I believe that because MTU problem isn't fix yet.

Thanks.

Best regards.

Gustavo Dias.

Hi Szymon,

I think the ntpd service is not a problem:

Hi Gustavo,

I was wondering if you managed to run successfull tests after your ntp stabilized?

Wrt the other problem of web interface could you check the SELinux settings in /etc/sysconfig/selinux. If it is set to enforcing, consider setting to permissive and rebooting and check again?

Regards,
