NAME

ipgrab - A Verbose Packet Sniffer

SYNOPSIS

ipgrab [ -blmnpt ] [ -c cnt ] [ -i if ] [ expr ]

IMPORTANT NOTE

DESCRIPTION

ipgrab reads and parses packets from the link layer through the application layer, dumping explicit header information along the way. It is a lot like tcpdump except that it prints almost every header field.

Options

-b
Buffer standard output. Useful when you're redirecting output to a file.
-l
Don't print link-layer headers.
-m
Minimal IP/TCP/UDP output.
-n
Don't print network-layer headers.
-p
Print packet payloads.
-t
Don't print transport-layer headers.
-c cnt
Terminate after receiving cnt packets.
-i if
Listen on interface if, e.g., eth0.
expr
Berkeley packet filter expression. See tcpdump(8) man page for details and examples.

BUGS

ICMP and DHCP/BOOTP support is not quite complete. L2TP support is flaky. RIP support is incomplete and SIP/SDP support is very rudimentary.
