perfSONAR User Q&A and Other Discussion

[Mark Yashar <>]

Hello,

I have installed perfSONAR on a VM (with CentOS OS) on a mac laptop for educational and testing purposes.

In order to set up tests between hosts with perfSONAR and to use perfSONAR toolkit commands such as bwctl,

iperf3, owamp, etc., along with the maddash dashboard, do I need an ethernet connection, i.e., a connection with an

ethernet cable between my mac laptop and an ethernet port or router, etc., or could these tests be carried out and

commands be successfully used with the wireless connection on the mac/laptop and shared with the VM?

Thanks,

- Mark

Hello,

I was able to resolve the last issue in the email threads below in connection with my attempts to install the perfsonar toolkit with CentOS  on a VM (VMware Fusion 8 for Mac OS X) on my mac laptop

via the CentIOS Toolkit ISO Installation option (thanks for your help on that), but as I am now going through the instructions on configuring the perfsonar toolkit for the first time at http://docs.perfsonar.net/install_config_first_time.html, I'm running into a problem when I'm trying to access the perfsonar web interface after step #7

(http://docs.perfsonar.net/install_config_first_time.html#accessing-the-web-interface). It seems that I'm not able to open up any browser or any kind of display within CentOS that I have installed 

on the VM. For example, when I try to open up a firefox browser, I get:

"Error: GDK_BACKEND does not match available displays"

and when I try to open up any kind of GUI or graphical display (such as xclock) I get the error:

"Error: Can't open display:"

I've experimented with different things around re-setting the display, such as:

"export DISPLAY = 0.0:"  , etc.

and I've downloaded a lot of additional X-Window display related software for CentOS such as:

yum install xorg-x11-xauth 

yum install xorg-x11-server-utils

but I continue to get the same error messages and cannot open up a browser or any other graphical display / gui.

Do you happen to have any suggestions on how I might be able to resolve this issue?

Many thanks,

Mark Yashar

…I reboot to restart the VM host and the VM restarts, I'm again presented with a screen asking

me how I want to Install the perfSONAR Toolkit system (like in step #1 under "Step-by-Step Guide using graphical installer" in http://docs.perfsonar.net/install_centos_netinstall.html) and it automatically goes back to the perfSONAR installation sequence…

 

 

Your installation probably went fine; it sounds like the ISO image didn’t get detached between the end of the installation and the next boot.  Been hit with that a few times myself.  :-)
