I saw an article about a Trojan horse program to change passwords on 
LaserWriters. In fact anyone can manually as well. So I thought I would
try to change mine. Not too difficult, because I have done a little
PostScript and I have got PostScript the blue book and PostScript
the red book. 

Changing the passord is 3 lines of postscript and that works fine.
The problem is after I turn the printer off and on again I can't print
anymore :-(. The error I get is:
  %%[Error:invalid access; Offending Command:exitserver] %%

This is the error you get when you do an exitserver with an incorrect 
password. Can I assume that the Mac is normally using the default
password of 0? If it is I think that's a real nuisance! Or am I
missing something?

Does it mean I have to leave the PassWord set at 0? With about 30
LaserWriters accessable on the net someone (not saying student) could
do a lot of damage changing names and passwords on printers.

Another question which I think has been raised before but I did not
see an answer is: How to you go back to the defaults? Rip the board
out and put it in the microwave on medium for 2 minutes I suppose. :-)


Thanks in advance
