Hi Fabrizio, I was just playing around a bit with xrdcp to see how it works. It seems that copying to a server only works at the second attempt: [noric01] ~/dev-xrootd/xrootd/bin/i386_linux24_dbg > xrdcp /tmp/heinz/testfile root://noric02.slac.stanford.edu:3000//tmp/testfile 041005 08:05:22 31927 Xrd: main (C) 2004 SLAC INFN xrdcp 0.1.0alpha 041005 08:05:22 31927 Xrd: (C) 2004 SLAC XrdClientAdmin 0.1.0alpha 041005 08:05:22 31927 Xrd: Stat Server [noric02.slac.stanford.edu:3000] did not return OK message for last request. 041005 08:05:22 31927 Xrd: SendGenCommand Server declared error 3011:Unable to state /tmp/testfile; No such file or directory 041005 08:05:22 31927 Xrd: (C) 2004 SLAC XrdClientAdmin 0.1.0alpha 041005 08:05:22 31927 Xrd: Create (C) 2004 SLAC INFN XrdClient 0.1.0alpha [noric01] ~/dev-xrootd/xrootd/bin/i386_linux24_dbg > xrdcp /tmp/heinz/testfile root://noric02.slac.stanford.edu:3000//tmp/testfile 041005 08:05:35 31931 Xrd: main (C) 2004 SLAC INFN xrdcp 0.1.0alpha 041005 08:05:35 31931 Xrd: (C) 2004 SLAC XrdClientAdmin 0.1.0alpha 041005 08:05:35 31931 Xrd: (C) 2004 SLAC XrdClientAdmin 0.1.0alpha 041005 08:05:35 31931 Xrd: Create (C) 2004 SLAC INFN XrdClient 0.1.0alpha I guess you've seen that too, right? I tested the CVS HEAD version.
