Hi Pete, o FZK - Gregory o status of setting up the xrootd system? As you know, I am taking over Rolf's work concerning xrootd at GridKa; the current status is that we have been able to see a file using xrootd on a test SL3 nas box but it still doesn't work when trying to access files on the Redhat 7.2 installed nas boxes. All of these machines are in the same sub-domain. The output show: Info in <TXNetFile::CreateTXNf>: Trying to connect to f01-001-106.gridka.de:1094. Connect try 1.
