Hello Paul,

This message from R.L. Nevot [r.nevot@private] seems to indicate that
we should see the exact commands that are executed:

"As fas as I know, this is done by default, sure you only have to
increase logging level: 
Sep  8 11:04:30 pix Sep 08 2006 11:04:29: 
%PIX-5-111008: User 'enable_15' executed the 'no access-list ...'
command.
Sep  8 11:04:44 pix Sep 08 2006 11:04:43: 
%PIX-7-111009: User 'enable_15' executed cmd: show access-list ... 
See the cisco documentation to know the meaning of messages 5-111008 and
7-111009"

We will test this out in our lab and let the list know.

I am also curious what the output will look like for commands excuted
via the PDM.

thanks,

Peter

Add the following lines to your PIX config:

logging enable
logging trap debugging
logging host inside [syslog server IP] udp/514

Then, when those messages are generated, they will appear in your syslog
stream.  But know that this will be a lot of syslog traffic on a busy
firewall, so don't implement this without proper planning and testing.  

Even so, that message doesn't mean what you may think it does.  The
'cmd' that you are going to see pretty much all of the time is 'enable'.
Sure it will tell you who modified the configuration and when (assuming
you have AAA set up for telnet/enable), but it won't audit the
configuration for you. You'll need a third party tool to do that.
