On the test, I will install the fprobe sensor, which will collect statistics from network interfaces and transmit it to the collector.

Now search for the package you want, select it for installation and click Accept. The package manager will then fetch the RPM package from your configured software repositories - and install it including any dependencies. After installation is complete the application should appear in the launch menu (unless it's a command line program).

Switch to the root user:

You can install fprobe on Ubuntu/Debian with the command:

To configure fprobe, open its configuration file:

And for example, we indicate:

The INTERFACE line indicates from which interface to intercept traffic, if necessary on all available ones, then specify “any”.
FLOW_COLLECTOR indicates the IP address and port on which the collector receives UDP packets.
OTHER_ARGS indicates other options. In this case, a filter is specified that selects only IP packets (ARP packets will not be taken into account).

Restart fprobe to apply the changes:

Check if fprobe is running and the collector is running:

Make sure that it is added to startup at startup of the operating system:

You can use flow-tools as a collector, see also my article:

I went to install bsnes the other day and for whatever reason the installation failed. Now, I cannot update, install new packages, or do basically any apt-get commands as they all try to process this broken package and fail.

'pre-removal' or 'post-removal' instead (in which cases the extension of the file to be edited would have been.prerm or.postrm).
