IceGrid.DeploymentException

I use AdminPrx to deploy ApplicationDescriptor to IceGrid and node.

Program run OK at my local computer, but when I upload it to remove Linux server, run it, and got the following error message:

IceGrid.DeploymentException
reason = "couldn't load `PsServer192.168.8.30' on node `192.168.8.30':
couldn't create configuration file: /tmp/servers/PsServer192.168.8.30/config/config"

What is the problem?
