README for SING v1.1
====================
"This program is distributed under the GNU GPL license. See the COPYING file
for more details."
SING stands for 'Send ICMP Nasty Garbage' :).
Sing is a little tool that sends ICMP packets fully customized from command
line. The main purpose is to replace/complement the niceful ping command
with certain enhancements as:
- Send fragmented packets (Linux and BSD).
- Send monster packets > 65534 (Linux and BSD).
- Send/read IP spoofed packets.(Libpcap included in distribution).
- Send/read Ethernet spoofed packets.(Libnet included in distribution).
- Send many ICMP Information types in addition to the ECHO REQUEST type sent
by default as Address Mask Request, Timestamp, Information Request, Router
Solicitation and Router Advertisement.
- Send many ICMP error types: Redirect, Source Quench, Time Exceeded,
Destination Unreach and Parameter Problem.
- Send to host with Loose or Strict Source Routing.
- Use fingerprinting techniques to discover remote OOSS.
- Send ICMP packets emulating certain OS: Cisco, Solaris, Linux, Shiva,
Unix and Window$ at the moment.
The ICMP packet types accepted on the command line follows:
Value Extended Value Meaning
----- -------------- -------
-echo --echo_req Echo Request. Sent by default.
-reply Echo Reply.
-mask --mask_req Address Mask Request.
-tstamp --timestamp Timestamp.
-rts --router_solicit Router Solicitation (Router Discovery).
-rta --router_advert Router Advertisement (Router Discovery).
-du --dest_unreach Destination Unreach.
-info --info_req Information Request.
-red --redirect Redirect.
-param --param_problem Parameter Problem.
-sq --src_quench Source Quench.
-tx --time_exc Time Exceeded.
This keys can be combined with multiple options like ICMP code (-x code),
no resolve (-n), garbage size bytes (-s bytes|max), etc.
See the man page for examples with deep details.
RETURN VALUES
Value Meaning
----- -------
0 Program finished OK
1 General error
2 Sent packet OK but received no response
3 Out of memory
-----------------------------------------------------------------------
IMPORTANT:
I released this program for evaluation of TCP/IP stacks *ONLY*. Take it
like a little tool to improve your system security, not for cracking,
disturbing or flooding another systems. This can be a crime on certain
countries.
-----------------------------------------------------------------------
I like to read your opinions, suggestions, bugs etc. about this program.
