Dear List Members, Thank you all for your earlier messages on this topic. I have been following the instructions for setting up son of grid engine on a single 32 core centos 6.5 machine from http://fsl.fmrib.ox.ac.uk/fsl/fslwiki/FslSge. However, I am stuck at the QMaster step, where the ./install_qmaster command results in the following error: Unsupported local hostname -------------------------- The current hostname is resolved as follows: Hostname: localhost.localdomain Aliases: localhost.localdomain localhost4 localhost4.localdomain4 localhost vhapalintersect localhost.localdomain localhost6 localhost6.localdomain6 localhost vhapalintersect Host Address(es): 127.0.0.1 127.0.0.1 It is not supported for a Grid Engine installation that the local hostname contains the hostname "localhost" and/or the IP address "127.0.x.x" of the loopback interface. The "localhost" hostname should be reserved for the loopback interface ("127.0.0.1") and the real hostname should be assigned to one of the physical or logical network interfaces of this machine. Installation failed. Any suggestions on what I am doing incorrectly would be greatly appreciated. Best wishes, Salil Soman, MD, MS
