Re: Fwd: Re: Suppress alerts

[Peter Rodger <prodger2008 () yahoo com>]

Hi,

Thanks for your help.  Sorry that I did not send whole
output to you.  Please see the attched output.txt and
there is an error stopped in log directory.  Can not
figure out why?

Frank, I did change the switch and the result is the
same as before.

Still get tons of open port alerts and desperately
need your help.

Thanks again,

Peter
