ntop is a network probe that shows network usage in a way similar to
|
|
what top does for processes. In interactive mode, it displays the
|
|
network status on the user's terminal. In Web mode, it acts as a Web
|
|
server, creating an HTML dump of the network status.
|
|
|
|
It sports a NetFlow/sFlow emitter/collector, an HTTP-based client
|
|
interface for creating ntop-centric monitoring applications, and
|
|
RRD for persistently storing traffic statistics.
|
|
|
|
ntop requires rrdtool, which is also available at Slackbuilds.org.
|
|
|
|
ntop needs to run under its own user/group. This has been assigned to
|
|
the following by SlackBuilds.org, but feel free to change it on your
|
|
system for consistency with local assignments.
|
|
User: ntop UID: 212 GID: 212
|
|
group: ntop GID: 212
|
|
|
|
If you want to change that, you'll need to change the script and
|
|
the rc.ntop to reflect your changes.
|
|
|
|
Logs are placed in /var/log/ntop/ and will be rotated every week. The
|
|
log rotation will restart the ntop server which will reset the ntop
|
|
statistics. If you want to keep the statistics you have to edit or delete
|
|
the /etc/logrotate.d/ntop file.
|
|
|
|
If you want to start ntop on system bootup:
|
|
|
|
/etc/rc.d/rc.local
|
|
==================
|
|
# Startup ntop
|
|
if [ -x /etc/rc.d/rc.ntop ]; then
|
|
/etc/rc.d/rc.ntop start
|
|
fi
|
|
|
|
/etc/rc.d/rc.local_shutdown
|
|
===========================
|
|
# Stop ntop
|
|
if [ -x /etc/rc.d/rc.ntop ]; then
|
|
/etc/rc.d/rc.ntop stop
|
|
fi
|
|
|
|
Additionally, you'll have to set the rc script to be executable just
|
|
like any other Slackware rc script.
|
|
# chmod +x /etc/rc.d/rc.ntop
|
|
|
|
When ntop is installed at the first time, you MUST set the
|
|
administration password for ntop (user 'admin'). You do that
|
|
by running ntop with the option -A (or --set-admin-password) as root.
|
|
# /usr/bin/ntop -P <ntop_homedirectory> -u <ntopuser> -A
|
|
For example:
|
|
# /usr/bin/ntop -P /var/lib/ntop -u ntop -A
|
|
It will prompt you for the password and then exit.
|
|
|
|
Running ntop:
|
|
Once ntop has started and configured correctly, you should be able to look
|
|
at all the data it's collected by pointing your browser at:
|
|
http://localhost:3000/
