Logging options

Quiet mode

Netcap writes a general summary to stdout, if you wish to disable output entirely use the -quiet flag:
$ net capture -quiet
When the quiet mode is used, the output is instead written into the netcap.log file in the directory where netcap is executed from.

Decoding errors

Errors when parsing packets are logged by default into the errors.log file in the current directory.
