Do I understand you right: You try to use FilerView from the machine the sim is installed on?
That won't work.
Try to use it from another machine.
E.g. I'm using it from my Windows machine to the (CentOS) VM the sim is installed in without problems.
From inside the CentOS VM, it won't work. (Like shooting yourself in the foot...)
It's the way the network interfaces are used...
