When I install the flowvisor, after starting the flowvisor with this command

sudo -u flowvisor flowvisor

In a new terminal I type the following to create an slice fvctl -f /dev/null add-slice upper tcp:localhost:10001 admin@upperslice

I get this errors in two terminals 2016-12-29 14:42:42.631:WARN::javax.net.ssl.SSLException: Received fatal alert: unknown_ca

Could not reach a FlowVisor RPC server at localhost:8081.
Please check that FlowVisor is running and try again.

Could somebody please help me? I am totally stopped by this problem.

I used the ubuntu 16.04 that would get unknown_ca problem, so I change to ubuntu 14.04 problem had gone. You may try that!

Did u solve the issue?

could not reach the RPC server at localhost:8081

this issue can be solved, when u use proper versions of Java, mininet, and ubuntu. I used the following combination and the error is gone:
jdk: 6 mininet 2.2.2 (VMware Workstation) ubuntu 14.04 (VMware Workstation) flowvisor from networkinglab tutorial GitHub.

One imp note: in mininet 2.2.2 installed version of java is 7. You have to uninstall it first and then u can install jdk6, jre6, maven.

I hope this helps! :)
