Hello, I have tried now using strace. The file strace.14 has been generated for cygwin-1.5.14-1, and strace.15 for cygwin-1.5.15-1. The command used was: > strace chmod +w /u/tmp/yahoo > /tmp/strace.15 2>&1 The concerned part from strace.14: ... 3310 116505 [main] chmod 1448 set_process_privilege: 0 = set_process_privilege (SeRestorePrivilege, 1) 244 116749 [main] chmod 1448 set_file_attribute: 0 = set_file_attribute (u:\tmp\yahoo, -1, -1, 0x124) 10376 127125 [main] chmod 1448 chmod: 0 = chmod (/u/tmp/yahoo, 0x124) 699 127824 [main] chmod 1448 chdir: dir '/c' ... And the same from strace.15 ... 199 5004896 [main] chmod 1436 fhandler_base::open: (u:\tmp\yahoo, 0x110000) 1441 5006337 [main] chmod 1436 seterrno_from_win_error: /netrel/src/cygwin-1.5.15-1/winsup/cygwin/fhandler.cc:668 windows error 5 216 5006553 [main] chmod 1436 geterrno_from_win_error: windows error 5 == errno 13 186 5006739 [main] chmod 1436 fhandler_base::open: C0000022 = NtCreateFile (0x0, E0100, u:\tmp\yahoo, io, NULL, 0, 7, 1, 4400, NULL, 0) 187 5006926 [main] chmod 1436 fhandler_base::open: 0 = fhandler_base::open (u:\tmp\yahoo, 0x110000) 181 5007107 [main] chmod 1436 fhandler_base::open_fs: 0 = fhandler_disk_file::open (u:\tmp\yahoo, 0x10000) 185 5007292 [main] chmod 1436 chmod: -1 = chmod (/u/tmp/yahoo, 0x1B6) 1226 5008518 [main] chmod 1436 open: open (/usr/share/locale/locale.alias, 0x0) ... The first thing I can see is that 'fhandler_base::open:' returns with the 'windows error 5' Is that the reason for chmod to fail later? Roman
