perfSONAR User Q&A and Other Discussion

[Amit <>]

Hi,

I am upgrading my perfsonar servers with 64 bit, but I saw strange issue
with my BWCTL test or NTP

When doing the bandwidth test, it shows me below errors

[root@perfchen
 ~]# bwctl -s 14.139.5.202
bwctl: Using tool: iperf
bwctl: 17 seconds until test results available

RECEIVER START
bwctl: start_endpoint: 3605232961.453831
bwctl: run_endpoint: receiver: 14.139.5.234

bwctl: remote peer cancelled test
bwctl: stop_tool: 3605232963.900632
bwctl: stop_endpoint: 3605232963.901162

But the tests with 32 bit perfsonar are working fine:

BWCTL versions: 1.5.1-20 (64 bit) and 1.5.1 (32 bit)
