Snort, problem with startup services



  • After fresh install PF 1.2.3 with snort beta (or normal), i can t started the service. What could be the problem?

    I have P4 2.8MHz, 3GB ram,… before it works OK,... only the difference is, new rules/category.

    How can i add more memory to snort? Do i need any change to done in config file?

    Thanks for your support

  • simby

    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



  • Thanks, fixed now. Do i need to do this on every update of snort rules?



  • now i have this problem:

    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 ;)



  • I have just tested and the code works.

    Do you have the latest code ?

    Do you have alerts that are not blocked ?

    James



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



  • Picture,… can you please fix this log reporting to fix the new theme :)






  • @simby:

    Picture,… can you please fix this log reporting to fix the new theme :)

    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.
