# icmplog.conf(5)

configuration file for icmplog(8).

## NAME

icmplog.conf - configuration file for [icmplog(8)](/icmplog/8.md).

## SYNOPSIS

*/etc/icmplog.conf*

## DESCRIPTION

The **[icmplog(8)](/icmplog/8.md)** configuration file is used to specify the level at which ICMP packets of a given type should be logged.

Log levels for packets are specified using the **\`type \[level\]'** rule described below.

A default log level can be specified with the **level** keyword, which is used for packet types which have not been explicitly assigned a level in the configuration.

The default syslog facility can be overriden with the **facility** keyword.

The \`except' keyword can be used to specify a list of hosts from which connections should be ignored.

Lines beginning with \`#' (shell-style comments) and blank lines in the configuration file are ignored.

An example configuration is included with the source distribution and is installed by default into */etc/icmplog.conf*

## KEYWORDS

- except \[host\], \[host\], \[host\]

  Specify a list of hosts to ignore connection requests from. The list can be comma or whitespace separated, and may contain fragments like \`192.168.' and \`.foo.com'. If the fragment is numeric, it is compared with the IP of the source host, otherwise the comparison is made with the resolved hostname.

- level \[level\]

  Specify the default logging level. The level  can be any one of IGNORE, ERR, WARNING, NOTICE, INFO and DEBUG.

- facility \[facility\]

  Specify the default logging facility. The facility can be any one of USER, DAEMON and LOCAL0-7.

- \[type\] \[level\]

  This is a generic rule which specifies the level at which packets of a certain type are logged. The type can either be numeric, or one of the keywords \`echoreply', \`destunreach', \`quench', \`redirect', \`echo', \`timeout', \`paramprob', \`timereq', \`timerep', \`inforeq' or \`inforep'. The level, as above, is a *syslog.h* symbolic constant.
