UNIX for Dummies Questions & Answers

Just hoping someone can help me out. I am looking for what should be simple commands to enter for this information:

List of all Unix users (is this etc/passwd?)
List of all users' access capabilities (is this etc/group?)
Password settings (e.g., password expiration interval, minimum password length, # of unsuccessful login attempts granted, etc.)

If someone could help me out with this ASAP, I would greatly appreciate it!

Thanks so much!!!

1. List of users
/etc/passwd would show local users
% cat /etc/passwd
If you are running NIS then you would have to do
% ypcat passwd
to show all NIS users. If the OS supports NIS+ the command is a little different - check your /etc/nsswitch.conf to see if either service is being used.

2.

3. Check /etc/default/passwd for settings and man page for info
% man -s4 passwd
% cat /etc/default/passwd


Sorry got to go - maybe someone else can pick up your second question.

Opps, sorry - that should have been
% man -s4 shadow
for info on forcing changes.

As far as question 2 - I agree with the next post - more info is needed. If a user belongs to a certain group and that group has access to a directory, then that could be thought of as access.

Again, if you are running NIS there could be more control on who gets access - a netgroup file could be in place which allows certain users access to the server and other can not login.

/usr/bin/admintool


This may help as well. If you are not very comfortable with using commands on the command line. This will tell you all the info you need about users on your system. What do you mean by "access capabilities"? Please be a little more specific.
