Parameters

pcap : str, default: None

Path to a pcap file.

iface : str, default: None

Name of a network interface.

pcap_list : str or list of str, default: None

• Path to a list of pcap files, e.g., '/tmp/myPcaps.txt'.
• Or list of path to pcap files, e.g., ['file1.pcap', 'file2.pcap'].

output_prefix : str, default: None

If None, automatically derived from input.

packet_mode : bool, default: False

Activate Tranalyzer2 packet mode.

plugin_folder : str, default: None

Path to the plugin folder. If None, default to $HOME/.tranalyzer/plugins.

loading_list : str, default: None

Path to a plugin loading list.

plugins : list of str, default: None,

A list of plugin names to load.

output_format : str or list of str, default: None

Select and configure the sink plugin(s) required to generate the requested output format. See also T2.add_output_format().

bpf : str, default: None

A BPF filter.

streaming : bool, default: False

If True, then T2.stream() can be used to yield one flow at a time.

Raises

OSError

If specified interface iface does not exist locally.

RuntimeError

def to_pandas(self, infile: str = None, delimiter: str = None) ‑> pandas.core.frame.DataFrame

Convert the flow file or infile to pandas DataFrame.

Parameters

infile : str

Path to a flow or packet file.

delimiter : str, default: None

Field delimiter used in the input file.

Returns

pd.DataFrame

DataFrame holding the tabular data stored in infile.

Raises

RuntimeError

If infile could not be found.

Examples

def unload(self, plugin: Union[str, List[str]] = None, plugin_folder: str = None, verbose: bool = False)

Remove (unload) plugin(s) from the plugin folder.

Parameters

plugin : str or list of str, default: None

plugin can be:

• a single plugin, e.g., 'pluginName'
• a list of plugins, e.g., ['pluginName1', 'pluginName2']
• a plugin loading list, e.g., 'myPlugins.txt'
• all to apply the operation to all available plugins
• If None, use T2.list_plugins().

plugin_folder : str, default: None

The plugin folder from where the plugin must be unloaded. If None, use T2.plugin_folder.

verbose : bool, default: False

• If True, print the output (stdout and stderr) of the command.
• If False, do not print anything.

Raises

subprocess.CalledProcessError

If the process exited with a non-zero exit code.
