Hay, that is a neat command :). 

Well, according to last, no one logged on but me during the time of the
"Issue". 

Thanks. I will add my ISP's DNS to the list and see if that helps. This
is the first time I have seen this message in ACID since I upgraded to
the new snort. That was better than a week ago.

Thanks

Joe

Should I add that to the list?

Yes. That will reduce your portscan alerts, but doesn't solve the problem 
of your host causing portscan alerts.

Also, I don't seem to have the 'lasts' command. What package is that
part of?

Oops. Make that singular "last".  It is a standard UNIX tool.

Thanks for the reply

Joe

No prob.

You might also want to check to see if any of the services you run from 
your server periodically scan hosts for some reason.
