Hi ,

        I have some probleams in CSIT test suites on Ubuntu 16.04 . There is a 
question "paramiko.ssh_exception.NoValidConnectionsError: [Errno None] Unable 
to connect to

port 22 on  or 192.168.255.102" when I finished  this command   
"./resources/tools/topology/update_topology.py -f -v -o 
topologies/available/vagrant_pci.yaml

topologies/available/vagrant.yaml"  followed  by  
https://wiki.fd.io/view/CSIT/Tutorials/Vagrant/Virtualbox/Ubuntu .  And aways 
circle "Permission denied, please try again."

after inputting the command "echo [email protected]{0,1,2} | xargs -n 1 
ssh-copy-id "


Thanks a million,
Rey
