Re: Still Empty log file

[Yonas Abebe <jonasabebe () gmail com>]

Hi James,

I didn't put the whole path for the file name in the output lines of
snort.conf (my mistake). Now, the output lines look like the following:

output unified2: filename /var/log/snort/snort.u2, limit 128
output alert_fast: /var/log/snort/snort.fast

Then i tried the same simple test using ping, tracert and nmap attack. Now
the snort.fast, barnyard2.waldo and snort.u2  contain some fixed size bytes
which doesn't grow although i repeated the test attack many times. Is there
something that I am missing?

I really appreciate for the help.
