My experience with FreeBSD is that the "default" behavior of directories is for files to have group ownership the same as the directory they are created in. For example here is a brief example bash-2.05# mkdir testdir bash-2.05# chown root:steve testdir bash-2.05# >testdir/testfile bash-2.05# ls -al total 10 drwxr-xr-x 5 root wheel 512 Mar 23 17:28 . drwxr-xr-x 19 root wheel 512 Jan 19 17:18 .. drwxr-xr-x 2 root steve 512 Mar 23 17:28 testdir bash-2.05# ls -al testdir/ total 2 drwxr-xr-x 2 root steve 512 Mar 23 17:28 . drwxr-xr-x 5 root wheel 512 Mar 23 17:28 .. -rw-r--r-- 1 root steve 0 Mar 23 17:28 testfile Or what am I missing? -steve To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
