MAC connects to campus network, INode

I'll take a few pictures and have a look.

sudo /Library/StartupItems/iNodeAuthService/iNodeAuthService start

Use this name to start the Inodeauthservice service. Inode to check the port of the mobile network card
But the second time I connect, I need to reboot to connect, so it's very troublesome, I don't want to restart the computer.
Fortunately, I messed up the whole problem solved.
Can not be connected after the first stop Inodeauthservice service, and then start the service, you can.
Stop service:

sudo /Library/StartupItems/iNodeAuthService/iNodeAuthService stop

And then start the service:

sudo /Library/StartupItems/iNodeAuthService/iNodeAuthService start

is the situation where the input stop service occurs after the connection:
