If you do this on the sly your best option is to use Wireshark. This program can scan every packet on your network and then you filter the results on the HTTP protocol. sudo apt-get install wireshark That installs the program.

The simplest method You can use ifconfig on you network interface (mine is eth0) - it counts the amount of data sent and received since the interface was started. # Bytes Receive ifconfig eth0 | awk '/RX bytes/ {print $2}' | awk -F: '{print $2}' # Bytes Transmitted ifconfig eth0 | awk '/RX bytes/ {print $6}' | awk -F: '{print $2}' # A human readable ...

I use nethogs ; it tells me the current usage and the processes: NetHogs is a small 'net top' tool. Instead of breaking the traffic down per protocol or per subnet, like most tools do, it groups bandwidth by process. NetHogs does not rely on a special kernel module to be loaded. Homepage: http://nethogs.sourceforge.net/ It is available in the ...

It's somewhat complex. You will need to create an alternative route table, use iptables to mark the package and add a routing rule to force the kernel to use the alternate routing table when the package is marked. You have a good tutorial for a somewhat more complex setup here.

You can install this by running the following command: sudo apt-get install ntop Once installed, go to http://localhost:3000/ to view the traffic conversations to determine what is talking with your machine. If you really want to dive down into the details ...

I can't say for sure. But what you're limiting is the actual file transfer. I'd guess that Transmission would still update the trackers at a regular interval. That shouldn't be too much data, but if you have many active torrents, it'll grow. Perhaps it keeps updating the list of peers as well.

Here is list of tools you can use

first of all you need to check your firewall status: ufw status than before you turn it on, probably you want to block all ports, all connections, just, everithing, and then to unblock what you need. ufw default deny then you add your rules, example: ufw allow from 111.222.111.222 to 80 but if you have more than one computer, you need for every same ...

That is a question requiring a very nontrivial answer. The following tools could all be useful to deflect an attack: nmap -A netstat -lnptu kill the /proc filesystem iptables the sentry tools suite These tools give you a lot of control if you know how to use them and will require some good "hobby time" to learn.
