How do I restore file privileges If you've upgraded your system and then restored files from backup tapes, some of the file privileges may have changed. If you are having problems that appear to be related to privileges, make sure all the privileges are intact. This can be done by running the script /etc/security/tools/setpriv. This command generates a script that may be executed from a shell prompt. This operation must be executed by root in single user mode: # /etc/security/tools/setpriv > /tmp/restore_privs # chmod 555 /tmp/restore_privs # /tmp/restore_privs > /dev/null 2>&1
