ok then, but would not it be more secure if you have maden the password files be able to read only by wheel group? for example I would not want somebody to get my passwd file and put it to web to show all usernames on my system and the real names corresponding to those login names (also I guess nobody would like that idea) or somebody may send email to all my users from that passwd file, is not it? (I do not think that somebody would like this idea too!), but those files are readable by public which means that anyone who as account on my system can access to them, why is that ? thanks, Evren PS. I hope I am not asking a stupid question ?
