If I do su user_name then I am allowed to do cat /etc/passwd , so it is possible to see what the passwd file contains, but I don't want that to be possible. I just need to add a user with minimal privileges possible.Furthermore , how can I get the new user restricted to it's home directory, so that it wont acces other users folders and files, without modifing the permissions of the other users folders and files (that would be a major job) ?


Many thanks
As far as I know all users can read /etc/passwd, but not write to it directly; a user can only wite to it indirectly using passwd, chsh, chfn. You cannot get the user restricted to his or her home directory only if it is about telnet/ssh access, but you can restrict him or her to the home directory if you mean ftp access.
