Hi 

Thanks for your hint.  The output had a error as I
forgot to specify -l in comand line.  The attached is
the right output after I specified -l switch in
command line.

Here is the last part of output:

*****************

It looked like it reads the threshold.conf but can not
suppress the alerts?  Why?

Any help will be appreciated.  I am just too upset
with that.


Thanks,

Peter

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?

 

ERROR:
[!] ERROR: Can not get write access to logging
directory "log".
(directory doesn't exist or permissions are set
incorrectly
or it is not a directory at all)

Fatal Error, Quitting..

D:\win-ids\Snort\bin>

Well... try to follow the instructions given. What's
the output 
configuration line? Have you tried replacing the '\'
with '/' or 
vice-versa in the logs path?

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

If Snort isn't starting how can you be getting
alerts? When you figure 
out what's wrong with the output dir send the
Snort's output concerning 
the thresholding.

Good hunting :)
