perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi,

To clarify, NDT was not removed from the host if it was already installed when you upgraded an existing host to 4.0. It is not shown on the main toolkit web page but the package should still be installed.  A new install will not have NDT though. 

As is being noted in this email thread, the firewall rules no longer include the NDT ports. You should be able to add them back with the following (and it should stick between future perfSONAR updates and reboots as well):

iptables -I INPUT 1 -m state --state NEW -m tcp -p tcp --dport 3001:3003 -j ACCEPT 

iptables -I INPUT 1 -m state --state NEW -m tcp -p tcp --dport 7123 -j ACCEPT 

iptables -I INPUT 1 -m state --state NEW -m tcp -p tcp --dport 843 -j ACCEPT 

/etc/init.d/iptables save

ip6tables -I INPUT 1 -m state --state NEW -m tcp -p tcp --dport 3001:3003 -j ACCEPT 

ip6tables -I INPUT 1 -m state --state NEW -m tcp -p tcp --dport 7123 -j ACCEPT 

ip6tables -I INPUT 1 -m state --state NEW -m tcp -p tcp --dport 843 -j ACCEPT 

/etc/init.d/ip6tables save

Above should work for most people, if you have other custom stuff in the rules, you want to tweak.

Thanks,

Andy

Check and see if you're running the version 4 toolkit version.  Apparently NDT has been removed from this.  I've got one running 3.5.1.7 and that has not had ndt removed yet.

Hello,

 

I was trying to access the ndt bandwidth test using my perfsonar. I used to access it at http://ndtserver-ft.datacom.upmc.edu:7123/, but it now no longer works. How do I get it back?

 

Thanks,
