.SH NAME
perroicmp \- ICMP packet logger.
.SH SYNOPSIS
.B perroicmp
[\-q] [\-lwr] [-i hostname[/mask]]
.SH DESCRIPTION
.B perroicmp
is a daemon that logs all ICMP packets that your host receives.
.SS OPTIONS
.TP
.I "\-q"
Quiet mode. Do not send output to stdout. Only error messages
are printed.
.TP
.I "\-l"
Make a simple human readeable log.
.TP
.I "\-w"
Log raw data, exactly as it was read from the socket, prefixing to each
packet, sizeof( time_t) bytes containing the date when the packet arrived.
You can later interpret this data, obtaining a detailed report of the
packet data using the program
.IR ipretperro .
.TP
.I "\-r"
Resolve domain names. By default the program won't resolve
IP addresses to domain names because of the slow down it produces.
.TP
.I "\-i hostname[/mask]"
Ignore packets.
.B
hostname
can be a hostname, a network name, or an IP address.
The
.B
mask
can be a network mask or a number that specify the number of ones
at the left side of the network mask. So, a mask of
.B 16
is the same that 
.IR 255.255.0.0 .
You can also use this option more than once, to ignore logging
packets from hosts that belong to different networks.
