# fwanalog(1)

iptables log-file analyzer

## NAME

fwanalog - iptables log-file analyzer

## SYNOPSIS

**fwanalog** *\[-h \| --help\] \[-c conffile\]\[-r\] \[-t \] \[-y\] \[-a IP-addr\] \[-p packet\]*\

## DESCRIPTION

This manual page documents briefly the **fwanalog** command. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.

**fwanalog** is a program that parses firewall log-files, and analyzes them with analog. For a complete list of supported log-files formats see */usr/share/doc/fwanalog/README.Debian*

## OPTIONS

The program follows the usual GNU command line syntax, with long options starting with two dashes (\`-'). A summary of options is included below. For a complete description, see the documentation in */usr/share/doc/fwanalog*

- **-h, --help**

  Show summary of options.

- **-r**

  Rotate log cache (not necessary anymore).

- **-t**

  Only update statistics for today (e.g. for hourly use). The sep\_hosts and sep\_packets commands in fwanalog.opts are ignored.

- **-y**

  Like -t, but only for yesterday

- **-a IP-addr**

  Create a separate report for this host

- **-p packet**

  Create a separate report for this packet.

  Format: target/protocol/portnumber

  e.g. 192.168.0.1/tcp/21 or firewall/udp/137
