Abbott

Alright, now tell me what you want.

Costello

Now look, I'm working in the IT department. Using UNIX over there. I gotta know the password. You know the password?

Abbott

For the root account?

Costello

Yeah.

Abbott

Yeah, I know it. You know, these days, for security reasons, you can use longer passwords, and they are putting numbers and puncuation in passwords.

Costello

Like what?

Abbott

Like asterisk, or colon.

Costello

Or semicolon.

Abbott

(double-take) Er, certainly.

Costello

So what's the password?

Abbott

Should I tell you here?

Costello

Why not?

Abbott

Okay. the password is not secure.

Costello

That's okay, we'll change it.

Abbott

Why? Is it too hard for you to type? To easy for crackers to guess?

Costello

I don't know.

Abbott

Why not?

Costello

You havn't told me the password.

Abbott

It's not secure.

Costello

Then we'll change it.

Abbott

To what?

Costello

Something. Anything. As long as it's secure.

Abbott

But it is secure.

Costello

You just said it was insecure.

Abbott

When did I say that?

Costello

Just now.

Abbott

No I didn't.

Costello

You said the password is not secure.

Abbott

That I did.

Costello

Then we should change it.

Abbott

What's wrong with the password being not secure?

Costello

Other people could break into our system.

Abbott

Well, we wouldn't want them to do that.

Costello

So it's agreed. It should be changed.

Abbott

To what?

Costello

Something more secure.

Abbott

That's the old password.

Costello

What's the old password?

Abbott

Something more secure.

Costello

Then why was it changed to be not secure?

Abbott

Password aging.

Costello

Password aging is a security measure, correct?

Abbott

Certainly.

Costello

So the password was changed.

Abbott

Naturally.

Costello

And the new password is insecure.

Abbott

No, but if you leak the password, then it will be insecure, yeah.

Costello

But the password is already not secure.

Abbott

You got it.

Costello

(sighs) Let me get this straight. I'm in charge of creating new accounts.

Abbott

Okay.

Costello

Someone just got hired and they need an account.

Abbott

Of course.

Costello

So I get this call, and I need to login to create an account. I login as root.

Abbott

To create the account, yes.

Costello

I enter root at the login prompt.

Abbott

Or you could use su.

Costello

Or I could use su. Nevertheless, I need to enter the password.

Abbott

Exactly.

Costello

So what do I enter for the password.

Abbott

It's not secure.

Costello

The password prompt? I'm at the console.

Abbott

Yes. You can login as root from the console.

Costello

So what do I enter for the password?

Abbott

I told you, the password is not secure.

Costello

Then after I login, I'll change it.

Abbott

If you are going to change the password, you need to tell the other admins.

Costello

Of course. So I login and change the password to something more secure.

Abbott

Can't do that.

Costello

Why not?

Abbott

The other security measure: password history.

Costello

What's that?

Abbott

Keeps people from changing their password back to their old password when their password ages too much.

Costello

So I'll make the password something more secure.

Abbott

You can't change the password to something more secure, that's the old password.

Costello

What's the old password.

Abbott

Something more secure

Costello

Something more secure than the current password?

Abbott

We tried that, but it's too long.

Costello

But I still can't get a shell prompt.

Abbott

Why not?

Costello

Because you havn't told me the password.

Abbott

I said the password was not secure.

Costello

All I'm trying to do is find out is what the root password is!

Abbott

I know.

Costello

So tell me.

Abbott

Tell you what?

Costello

The root password.

Abbott

I told you. Wait a minute, which system do you want the root password for?

Costello

The NIS master system.

Abbott

I told you.

Costello

You said the password was insecure.

Abbott

No, I didn't. I said the password was not secure.

Costello

But it used to be more secure.

Abbott

Well, it used to be something more secure.

Costello

How secure was it?

Abbott

It was pretty secure, until it was leaked out. Then we changed it to something more secure.

Costello

First, it was pretty seecure, then it was something more secure, and now it's not secure?

Abbott

Now that's the first thing you said right.

Costello

I don't even know what I'm talking about! Okay, forget about the NIS master system. Say I need to change the web server configuration.

Abbott

It's been known to be required.

Costello

So, I need to login to the web server. What password should I use there.

Abbott

The password for the web server?

Costello

Yes.

Abbott

Right now, it's the same as the password for the NIS master server.

Costello

Two systems with the same password? That's not secure.

Abbott

Exactly. That's why we are going to change it.

Costello

Of course.

Abbott

As you were saying, you were going to login to the web server.

Costello

And the password is not secure.

Abbott

Naturally.

Costello

So I'm at the password prompt, and I enter the insecure password.

Abbott

Naturally.

Costello

Which is?

Abbott

Not secure.

Costello

I know that.

Abbott

So now you can reconfigure the web server.

Costello

(shrugs) The web server password is insecure. When is it going to be changed.

Abbott

Later today.

Costello

So when I come in tommorrow, and login to the web server, I'll need to give it the new password.

Abbott

That's the password for the gateway machine.

Costello

What's the password for the gateway machine?

Abbott

The new password.

Costello

Is it secure?

Abbott

No, it's the new password.

Costello

Passwords that have just been changed are more secure than passwords that have aged, right?

Abbott

Correct, assuming only the proper people know.

Costello

So the password for the NIS master is not secure, the root account on the gateway machine has the new password and the web server password is not secure today.

Abbott

Yes.

Costello

Can't we just install sudo?
