Hey Robert,

I’m still not able to get to port 3001 from desk179.internet2.edu. That aside, if port 7123 is being allowed to the world, ports 3001, 3002 and 3003 need to be as well for NDT to function properly.

Cheers,

Aaron

Okay, try again.  I've got my firewall guys to open up the IP you sent
me before.

Hey Robert,

Is there a firewall up on the host or anything? When I try to telnet to port 3001 (the NDT server side port) on the host, it just times out. e.g.

[aaron@desk179 ~]$ telnet 129.82.100.205 3001
Trying 129.82.100.205...

Cheers,
Aaron

Hello!  After updating NDT to the latest version via yum I'm unable to
pull any results out off of the test.  The logs seem to indicate an
inability access the Tcpbw100 file, but file permissions seem to be fine
from what I can see.  Does anyone know what I need to do to get NDT to
run tests again?   URL://speedtest.colostate.edu:7123

Thanks in advance,
Robert
