I have found

/etc/init.d/ndt

to restart the failed web100srv process.

Thanks!

esmond_latency_localhost and esmond_latency_traceroute directories

Hi Michael,

I think that the problem is probably solved. As I was trying to gather the
file:
/opt/perfsonar_ps/regular_testing/etc/regular_testing.conf

I noticed that this file is 500 +MB in size, one of the description field was
filled with the dreaded "\\\\...", after I used sed to remove the offending
character, I restarted the regular_testing again. It appears to run just
fine. I will keep my eye on it and I was able to get into the "Configure
Tests" Tab.

I don't quite know how this configuration file got corrupted. Thanks again
for leading me to the "debug". By the way, do you know which command I
should run to start the "stopped" Network Diagnostic Tester (NDT) Not
Running"?

Have a great Holiday Season.

Hi Zhi-Wei,

Has this been resolved? If not, can you please send

/opt/perfsonar_ps/regular_testing/etc/regular_testing.conf

You'll want to remove passwords from the file, or send it directly to me.

Thanks,
Michael
