[confidential]
Dear Fiware Lab Helpdesk
Hi, I'm a one of FIWARE Lab Noida Node user in Japan.
The network condition between my PC and VM on Noida Lab seems not good.
I have tested following scenario to confirm network condition.
[scenario]
PC(Japan) --------->> Network ----------->> FIWARE Lab VM(India)
114.179.233.245 180.179.214.169
1. Send 100MB file from my PC to FIWARE Lab VM with scp and measure the elapsed time.
2. Repeat above operation 5 times and obtain following result.
[result]
[root@fiware1 ~]# time scp 100MB_File lab:/home/centos
100MB_File 37% 37MB 2.0MB/s 00:31 ETApacket_write_wait: Connection to 180.179.214.169 port 22: Broken pipe

I tested above scenario and noticed network condition isn’t good.
[request]
Could you tell me why network condition isn't good if you know something?
Best Regards

Thanks for reporting the issue, however we haven't noticed any issue with respect of network condition currently w.r.t Noida node. Could you please try again or check your network for the same.
As we are able to do scp successfully. PFA scp logs(Scp_logs_02072018.txt) for the same.
