Hi Pete Chris and I discussed with the relevant person at RAL upgrading the operating system for the xrootd servers from RedHat 7.2. They are happy to make the upgrade, but they would much rather upgrade to Scientific Linux 4. This doesn't help us regarding using the available rpms, but I guess we can just build them ourselves (or even see if we can use the SL3 rpms). Before we look into the testing the setup we wanted to see if there were any objections running the xrootd servers on SL4? cheers Manny
