Hello, As I had suspected the xrootd/olbd logfiles permissions got screwed up after the daily move to a new file. Namely, I just granted read access to these files (as requested Peter) but after midnight the new file got the default file access again. -rwxr-xr-x 1 xrootd wheel 362234 Feb 18 22:14 /tmp/babar2.olblog.20050218 -rwxr-xr-x 1 xrootd wheel 130996 Feb 18 23:00 /tmp/babar2.xrdlog.20050218 -rw------- 1 xrootd wheel 1208 Feb 19 00:04 /tmp/babar2.olblog -rw------- 1 xrootd wheel 388 Feb 19 01:00 /tmp/babar2.xrdlog -- Gregory -------------- Dr. Gregory Schott -------------- Institut fuer Experimentelle Kernphysik (IEKP) Universitaet Karlsruhe - Postfach 3640 76021 Karlsruhe (Germany) tel.: +49-(0)724782-3537 fax.: +49-(0)724782-3414 e-mail: [log in to unmask] -----------------------------------------------
