[Paraview] why can't I connect a remote server on cluster ?

[Peter Debuchev]

Hi Hengxing,
which commands did you run precisely on which machine? Did you check that
port 11111 is available on the server for the client or, in the case of the
reverse connection, available on the client for the server?

when I started a remote server(./pvserver), it failed with the ERRORs

The errors with vtkClientSocket seem like a problem of a client, was is
really pvserver, which failed with those messages?
