    This little piggy caught some hackers

    I just got my snort up and running and was looking through my logs when I saw this packet.

    If you look close to the top you see the words "this little piggy caught some hackers"

    What does this mean? Did it actually catch someone or am I just so new to this that its nothing to worry about.

    I don't know if you've already done this... but it might help you to install and use some sort of log analyzer.

    http://www.snort.org/dl/contrib/data_analysis/

    Sorry I couldn't have been more help than that... but I've never really played with snort.

    Yeah, an analyzer breaks it down for you very nicely. I would personally reccomend ACID (Analysis Console for Intrusion Detection) its a tad bit on the slow side if you have a lot of requests to process, but it works GREAT.

    Hope the helps somewhat

    if you go over to http://www.astalavista.com/library/ids/win2ksnort.shtml

    this link shows you how to use ACID to analyse snorts info and then it uses some PHP and MySql to put incidents in a database, looks very nice from what ive seen i need to get it set up on my network

    Its a pretty comprehensive tutorial

    teehehehe i thought that html on the side made something that looked familiar, did you go to the snort website at this time??

    if you go to http://www.snort.org/ and then put the cursor above the picture of the pig, youll get the message "this little pigey caught a hacker", that thing in the logs is just logs of snorts webpage

    if you get rid of the hex on that log and then join up the tags and words together, get rid of the full stops then its almost an exact replica of snorts page, the only difference is the logs finishs before the website can be properly formated

    Ummm...just looking at this...it looks to me like you found Snort's web site

    08/21-12:25:22.876338 0:6:25:E4:80:1 -> 0:4:5A:65:94:65 type:0x800 len:0x59A
    199.107.65.177:80 -> 192.168.1.101:33572 TCP TTL:52 TOS:0x0 ID:59875 IpLen:20 DgmLen:1420 DF
    Name: www.snort.org
    Address: 199.107.65.177
    Aliases: 177.65.107.199.in-addr.arpa

    It looks to me like you requested www.snort.org and the packet you pasted is merely part of the reply from the server that was returning the web page. I don't see anything unusual here...

    /nebulus
    There is only one constant, one universal, it is the only real truth: causality. Action. Reaction. Cause and effect...There is no escape from it, we are forever slaves to it. Our only hope, our only peace is to understand it, to understand the 'why'. 'Why' is what separates us from them, you from me. 'Why' is the only real social power, without it you are powerless.

    I'll second Nebulus200s opinion. It looks like you requested a page at the snort website and you just captured it's response.

    /me goes and runs in a hole and never comes out.

    oops.

    Well I never used snort before, and I haven't really learned how to accurately read packets, but I think I'm gonna start finding tuts on how to read packets.
    Thanks for the help guys.
