Ntop

[prairie-guy]

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

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

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.
