perfSONAR User Q&A and Other Discussion

[Justin Ettore <>]

1. I’m trying to finish up 2 installation of PerfSONAR and can’t seem to be able to configure the correct Host Status primary interface on the toolkit page.  I have been editing /opt/perfsonar_ps/toolkit/web/root/gui/services/etc/web_admin.conf to make changes.

System 1 –  http://perf-brb.net.isc.upenn.edu/toolkit/  - current primary address – modv.perf-brb.net.isc.upenn.edu

        [perf-brb etc]$ more web_admin.conf

logger_conf     logger.conf

allow_internal_addresses  0

primary_interface          p2p1 

p2p1      Link encap:Ethernet  HWaddr A0:36:9F:2C:62:7C  

          inet addr:128.91.172.58  Bcast:128.91.172.59  Mask:255.255.255.252’

58.172.91.128.in-addr.arpa name = scidmz.perf-brb.net.isc.upenn.edu.

System 2 –  https://perf-hnt.net.isc.upenn.edu/toolkit/ - current primary address -  perf-hnt.net.isc.upenn.edu

[ettorej@perf-hnt etc]$ more web_admin.conf 

logger_conf     logger.conf

allow_internal_addresses  0

primary_interface          p1p1

p1p1      Link encap:Ethernet  HWaddr 90:E2:BA:2B:C8:28  

                   inet addr:128.91.94.14  Bcast:128.91.94.15  Mask:255.255.255.252

14.94.91.128.in-addr.arpa name = hnt-brdr.perf-hnt.net.isc.upenn.edu.

Is this setting coming from somewhere else then?

Question 2 – I posted this before and have tried many configuration options but nothing that seems to work as I was hoping.  My server have 4 interface being used.  2 10gb for perfSONAR and 2 1gb for management and backup.  The 2 10gb interfaces connect to different subnets/routers to provide multiple test points.  I really only want the 2 10gb available for all PerfSONAR services but there does not seem to be a good way to configure this.  Seems like I need to have all 4 interface available for testing and then use IPTables to block any connection to the interfaces I do not want available.  Is this the correct assumption, or am I missing a better way to handle this?

Thanks
