I got 2 problems ,please advise

[godcronos]

I am typing "last" to see the last users that logged on and I get " last: /var/log/wtmp: No such file or directory
Perhaps this file was removed by the operator to prevent logging last info."
-Please help me be able to get the command to work.

How can I turn off the IPP service. I tried putting the PC running backtrack on the DMZ and it shows me that it has IPP-port 631 OPENED. I don't need it and I don't want a running service that I don't need and could be a backdoor on the system.
How can I please disable that service?

Thank you in advance!!
