Sorry, this all my fault.

There is a bug in snort-dev, rule files are not being copied over after updates.
Rules are only being copied after interface creation.

Fix

Manually copy "cp /usr/local/etc/snort/rules* /usr/local/etc/snort/snort_myinterface/rules

or

Delete all your interfaces.
Update your rules.
Create your interfaces.

Merry Christmas
James

simby

Updated code…...
Am all done with snort_blocked.php and snort_alerts.php.

snort_rules.php is to slow.

Im adding code to make it faster.

James

On alerts blocked we have this error:

Warning: array_unique(): The argument should be an array in /usr/local/www/snort/snort_blocked.php on line 345 Warning: Invalid argument supplied for foreach() in /usr/local/www/snort/snort_blocked.php on line 350 ;)

jamesdean

I have just tested and the code works.

Do you have the latest code ?

Do you have alerts that are not blocked ?

James

simby

Yes, i have the last code from today,… i will add you later picture.

simby

Updated code to deal with corrupted alerts file, said error should be fixed now.

Now Im working on snort_rules.php trying to make it faster.
