Etterlog Description

Etterlog is the log analyzer for logfiles created by ettercap. It can handle both compressed (created with -Lc) or uncompressed logfiles. With this tool you can manipulate binary files as you like and you can print data in different ways all the times you want (in contrast with the previous logging system which was used to dump in a single static manner). You will be able to dump traffic from only one connection of your choice, from only one or more hosts, print data in hex, ascii, binary etc…

TIP: All non-useful messages are printed to stderr, so you can save the output from etterlog with the following command:

etterlog [options] logfile > outfile

Thus you can dump for example a binary file from an ftp connection if you print the data in binary mode, without headers and selecting only the ftp server as the source of the communication.
