Re: Still Empty log file

["Lay, James" <james.lay () wincofoods com>]

Yonas,

 

Config looks good...could use tuning when you can.  For a test, put this
into your local.rules file:

 

alert icmp any any -> any any (msg:"ICMP test"; classtype:bad-unknown;
sid:10000016; rev:1;)

 

Then save and start up snort.  Ping to or from the machine you're
running snort on, and you should see alerts things both in the u2 file,
and snort.fast file.  Lemme know how it goes.

Hi Yonas,

 

Can you put in your snort.conf here?  That will help.  Also, if say your
HOME_NET is for example 192.168.1.0/24, and you're scanning/pinging from
another IP on that same network, Snort won't see it as it's on the same
LAN.

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.

Hi all,

I am having problems with empty output log files. I am running Snort
2.9.2.2 on Ubuntu virtual machine by following the guide at the Snort
page. I have barnyard2 installed to send output to Mysql....unified2
output is configured on snort.conf. I started snort with a command  

sudo /usr/local/snort/bin/snort -u snort -g snort -c
/usr/local/snort/etc/snort.conf  -i eth0 

I started barnyard2 with the command

sudo sudo /usr/local/bin/barnyard2 -c
/usr/local/snort/etc/barnyard2.conf -d /var/log/snort -f snort.u2 -w
/var/log/snort/barnyard2.waldo

The output of barnyard command is OK but shows, WARNING: Ignoring
corrupt/truncated waldofile.

For a simple test i did nmap attack,Snort creates the log files in
/var/log/snort but the size is always empty. i can see the output on the
console though. I have tried to research and apply almost all the advice
on similar issue in this mailing list but none of them helped me. Could
you please help me?

thanks 




Yonas,

What are your output lines in your snort.conf?  Something like the
below?

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

If not, for testing, try adding the alert_fast to see what happens
there.  Also, try the command u2spewfoo on your snort.u2 file and see
what that shows.

James
