    Default Ntop

    I am running Backtrack 4 on a MacBook Pro with VMware by Fusion. Generally, runs quite well.

    I have not been able to get ntop to work. The message I get is along the lines of:

    **ERROR** RRD: Disabled - unable to create directory (err 13, /var/lib/ntop/rrd/graphics)

    I have tried 'chmod -R 777 rrd'. No luck. Google shows that I am not the only one with this probem.

    I also tried executing as a different user--no good.

    I attempted to download the source and compile it. After getting all of the dependencies figured out, I still got similar error messages, all related to rrd.

    Thanks,

    Bryan

    hi bryan,

    mkdir -p /var/lib/ntop/rrd
    chmod 0777 /var/lib/ntop/rrd

    works fine

    Default Ntop Fails to Start

    Thanks for your suggestion. I've tried that in various permutations. Still the same result.

    If this isn't a problem that others are having, I wonder if this is a result of running backtrack on VMware. Just to open up all the permissions, I first utilized:

    root@bt: chmod -R 0777 /var/lib/ntop

    I also have removed and reinstalled with apt-get.

    Here is the listing of errors:

    hi,

    try this:

    sudo rm -r /var/lib/ntop/*
    sudo chown ntop:ntop /var/lib/ntop >>(ntop user/group already exists under BT4)
    sudo ntop -i eth0 -u ntop

    I'm using the included BT4 ntop version:
    ii ntop 3:3.3-11 display network usage in web browser

    Default NTop Fails to Start

    brtw2003,

    Thanks for advice. Running it as ntop as user 'ntop' vs. root didn't make a difference--same error messages.

    This may just be a problem running bt4 on Vmware on OS X rather than a problem with ntop running natively.

    If anyone running bt4 under Vmware reads this post, I would be curious if they are able to run ntop.

    Bryan
