NetMeter

prepare

host:

apt-get install python3 python3-numpy iperf gnuplot
// winexe for windows guest

guest:

// ssh server
apt-get install iperf

sshkey:

# generate host key
host$ ssh-keygen -t rsa -f ~/.ssh/net_meter
# set key to client
host$ cat ~/.ssh/net_meter.pub | ssh -p <ssh_port> <ssh_user>@<ssh_host> "cat >> ~/.ssh/authorized_keys"
# test if ssh-key is success
host$ ssh -p <ssh_port> <ssh_user>@<ssh_host> -i ~/.ssh/net_meter

# also set host key to client2

NetMeterConfig.py and creds.dat

• shutdown=False: Will NetMeter close client at the end of test?

• key in creds.dat could’t use ~ in path.

note

• running

  • different buffer size in iperf: iperf -l

  • cpu usage?

  • time control: wait 30 sec

  • TCP/UDP protocol

  • multi-thread

• render plot and html
