The purpose of this program is to calculate flow statistics from a given capture file. Flowtbag was designed with offline processing as the primary focus.
To run the executable, you will need libpcap installed. On a debian based system, the following command will install the appropriate library:
apt-get install libpcap
Other distributions will likely have a similar package name.
To compile from source, you'll need a Go compiler, libpcap headers, and gopcap.
Please see http://golang.org/doc/install.html
On a debian based system, you can execute the following command:
apt-get install libpcap-dev
Other distributions will likely have a similar package name. It is important that if you are compiling the program from source, you install the developement headers.
Once libpcap is installed, go will install the necessary go dependencies. Just
build and install using go.
go get github.com/danielarndt/flowtbag
The program's usage is currently left undocumented due to the rapidly changing functionality of the program in its early stages. However, if you run flowtbag, the currently implemented options should be displayed. A typical use case might look something like:
$ ./flowtbag test.cap > test.out
Flowtbag currently has two seperate channels for output. To stdout, a stream of comma seperated values is output. Line by line, these represent the flows in the capture. The features output are given, in order, in section 4.1. The second output channel is stderr. This is where reports, as well as any debugging information is displayed. This allows the user to redirect output to a text file, and still receive updates as the program runs. The setup for output is likely to change in future versions of Flowtbag when a better system is designed.
