(which history >has shown doesn't work anyway) and how do i get around it ? Yes there is use in using shadow passwd databases. Are you saying that cracking DES is trivial? (Not a dictionary attack on user passwords, but the cipher itself.) To get around it just don't even install DES or the like to begin with. I don't recommend it. Security is a puzzle. You don't want to give away any pieces if you can help it. Keeping passwords in the clear certainly is not recommended. >another problem is that i can't change a users home directory. if i change >it to something different and log in i'm sent to "/". changing the password >of that user overwrites my changes that i made to /etc/passwd and >/etc/master.passwd and replaces the home directory entry with the old one. Again 'vipw' To change a password use the 'passwd' command. >last but not least ... is there a way to search the old digests of the You can search the archives.
