Ok, here's a reproduction on what you did: # ll /var/db | grep my drwx------ 10 mysql mysql 512 Oct 5 20:15 mysql itetcu@it> /home/itetcu/tmp/test [12:33:33] 0 % touch test1/1 itetcu@it> /home/itetcu/tmp/test [12:33:42] 0 % touch test1/2 itetcu@it> /home/itetcu/tmp/test [12:35:01] 1 % ll total 74836 drwxr-xr-x 2 itetcu wheel 512 Oct 6 12:33 test1 drwxr-xr-x 2 itetcu wheel 512 Oct 6 12:33 usr itetcu@it> /home/itetcu/tmp/test [12:35:03] 0 % su Password: root(itetcu)@it> /home/itetcu/tmp/test [12:35:47] 1 # chown -R mysql:mysql test1 root(itetcu)@it> /home/itetcu/tmp/test [12:35:50] 0 # ll total 74836 drwxr-xr-x 2 mysql mysql 512 Oct 6 12:33 test1 drwxr-xr-x 2 itetcu wheel 512 Oct 6 12:33 usr root(itetcu)@it> /home/itetcu/tmp/test [12:35:56] 0 # chmod -R 0700 test1 root(itetcu)@it> /home/itetcu/tmp/test [12:36:16] 0 # ll total 74836 drwx------ 2 mysql mysql 512 Oct 6 12:33 test1 drwxr-xr-x 2 itetcu wheel 512 Oct 6 12:33 usr root(itetcu)@it> /home/itetcu/tmp/test [12:36:17] 0 # ll test1 total 0 -rwx------ 1 mysql mysql 0 Oct 6 12:33 1 -rwx------ 1 mysql mysql 0 Oct 6 12:33 2 root(itetcu)@it> /home/itetcu/tmp/test [12:36:22] 0 # cp -Rp test1/ usr/ root(itetcu)@it> /home/itetcu/tmp/test [12:36:35] 0 # ll total 74836 drwx------ 2 mysql mysql 512 Oct 6 12:33 test1 drwx------ 2 mysql mysql 512 Oct 6 12:33 usr As you notice, because of -p flag now the owner / permission on usr are those of test1, so in your case /usr now belongs to mysql and mode 0700. At console do: # chown root:wheel /usr # chmow 0755 /usr This probably will fix also the first (/home/reports) problem, as I believe /home an your system is a symbolic link to /usr/home. -- IOnut Unregistered ;) FreeBSD "user"
