# icmplog(8)

ICMP packet logger.

## NAME

icmplog - ICMP packet logger.

## SYNOPSIS

**icmplog** \[-f, --file *filename* \] \[-n, --no-resolve\] \[-v, --version\]

## DESCRIPTION

**icmplog** , a ICMP packet logger, is a part of the **jail** (just another ip logger) package.

icmplog is a small (daemon) process which logs all ICMP packets to the local host. The syslog level at which a given packet is logged is configurable depending on the ICMP type of the message. Packets from specific hosts can be ignored, and a default log level can be specified.

icmplog can be useful in detecting attempted denials of service, and monitoring network traffic, especially when used in conjunction with **[tcplog(8)](/tcplog/8.md).**

The configuration is explained in the **[icmplog.conf(5)](/icmplog.conf/5.md)** manual page.

## OPTIONS

- \-f, --file \[ filename \]

  Use *filename* as the configuration file instead of the default *(/etc/icmplog.conf).*

- \-n, --no-resolve

  Do not resolve IP addresses to hostnames.

- \-v, --version

  Display **[icmplog(8)](/icmplog/8.md)** version.

## SEE ALSO
