Hey Amit,

Could you try adding the "-i 2" flag and seeing what the result is?

Cheers,

Aaron

Subject: BWCTL- remote peer cancelled test

 

Hi,

 

I have connected 6-7 perfsonar servers in my network. Now I would like to test the bandwidth of the link connecting these servers. So I planned to run scheduled test from server1 to other 5 servers.

But It doesn’t seems to run. It shows error “remote peer cancelled test”. Also I don’t see any graph.

Please find attached logs

 

Can’t I ran more than one scheduled bandwidth test at a time?

 

Also find below output of ps auwx

 

[root@localhost ~]# ps auwx | grep bwctl

Please Help, as very soon I am going to deploy perfsonar servers into my country wide network.
