ngrep strives to provide most of GNU grep's common features, applying
|
|
them to the network layer. ngrep is a pcap-aware tool that will allow
|
|
you to specify extended regular or hexadecimal expressions to match
|
|
against data payloads of packets. It currently recognizes IPv4/6,
|
|
TCP, UDP, ICMPv4/6, IGMP and Raw across Ethernet, PPP, SLIP, FDDI,
|
|
Token Ring and null interfaces, and understands BPF filter logic in
|
|
the same fashion as more common packet sniffing tools, such as tcpdump
|
|
and snoop.
|
|
|
|
ngrep is built with IPV6 support by default; to disable it, do this:
|
|
NGREP_IPV6=no ./ngrep.SlackBuild
|
|
|
|
A patch is included for IPV4 and IPV6 packet reassembly applied by
|
|
default. The patch adds the -r switch to ngrep. To disable the patch,
|
|
do this:
|
|
ASSEM_PATCH=no ./ngrep.SlackBuild
