    but base page is blank. Any idea?
    No idea

    snort logs according to rules. So I am guessing a problems with mysql.

    tronnix : You need to register with snort before you can download rules.

    Well then download the rules

    Notice, they limit how often you can download, I think there is a 10 or 15 minute time out.

    Re: Intrusion Detection

    I had a lot of trouble using wget. So I just downloaded the file to my desktop using Firefox, then copied the file to the directory that I wanted like /usr/src/snort or /etc/snort/ .

    Good luck

    Re: Intrusion Detection

    Hi Bodhi,
    My problem is not mysql. I see alerts there:
    Code:
    mysql> show tables;
    +------------------+
    | Tables_in_snort  |
    +------------------+
    | acid_ag          | 
    | acid_ag_alert    | 
    | acid_event       | 
    | acid_ip_cache    | 
    | base_roles       | 
    | base_users       | 
    | data             |

    I just do not see them in BASE. I also do not see a sensor. BTW, I did not see anything about us having to install ACID. Did I miss a step? Other procedures I have seen about this, involves installing ACID.

    Re: Intrusion Detection

    this part is confusing:
    I mostly copy and pasting but the URL i copy are not correct.


    wget http://www.snort.org/the_rules_you_wish_to_use

    Re: Intrusion Detection

    If you downloaded snort 2.8.x ( x = whatever revision ), then you want this url:
    Code:
    http://www.snort.org/pub-bin/downloads.cgi/Download/vrt_os/snortrules-snapshot-2.8.tar.gz
    Bodhi just wrote it that way, meaning you need to select which version or rules matches your snort file.

    Re: Intrusion Detection

    I think I have an issue with the way I set up the permissions. I see a couple of other posts regarding missing sensor id in mysql, which causes BASE not to show anything. How can I get more information about this and troubleshoot it please?

    Re: Intrusion Detection

    thanks for the URL that worked now i went to the next command
    cd snort2.8.3 what does this mean there is no directory for that

    I downloaded that latest snort 2.8.4
