That's entirely irrelevant since FastRWeb doesn't use TCP/IP - make sure you are running the correct Rserve settings which are *not* on port 6311. All you need to do it to use the start script.

You seem to have permission issues on the socket or the FastRWeb directory - check the permissions on
/var/FastRWeb/socket
You should make sure that _www has both read and write access. Remove it before starting if in doubt. If it's not there, make sure that the user under which you run Rserve has write permissions in /vat/FastRWeb. That applies to the other directories as well - it will need write permissions on tmp and _www must be able to read web.R and tmp.

Cheers,
Simon
