Code listing 12 in Part 1, Chapter 2 of the PPC handbook 2006.1 shows how to add a user, and code listing 13 shows how to su to root, but there is no mention of adding the user to the wheel group. Please change code listing 12 from: # useradd -m -G users john # passwd john New password: (Enter john's password) Re-enter password: (Re-enter john's password) To: # useradd -m -G users,wheel john # passwd john New password: (Enter john's password) Re-enter password: (Re-enter john's password) Or make mention of the fact that membership in the wheel group is prerequisite to using 'su'. Thanks
Code listing 13 shows how to su from root to john, not vice versa. Thanks for reporting, anyway.
whoops, that's totally right :-S My bad!
