Free icmp codes software for linux

ICMPInfo is a tool that uses ICMP type 13 and 17 to retrieve the current time of a remote host and its netmask.

ICMPScan scans the specified address, or addresses, for ICMP responses.

Usage:

icmpscan [ -EPTSNMAIRcvbn ] [ -A address ] [ -f filename ] [ -i interface ] [ -r retries ] [ -t timeout ] target [...]

Options:

-i, --interface
Listen on the specified interface. If unspecified, icmpscan will examine the routing table and select the most appropriate interface for each target address.
-c, --promisc
Put in interface into promiscuous mode. As this option increases the load on the system in general, it should only be used if spoofing of source packets address is enabled with the "-A" option.
-A, --address
Specify the source IP address of generated packets.
-t, --timeout
Specify the timeout, in milli-seconds, before retrying.
-r, --retries
Specify the number of attempts to elicit a particular ICMP response.
-f, --file
Read target list from the specified file.
-E, -P, --echo, --ping
Check of ICMP Echo responses.
-T, -S, --timestamp
Check for ICMP Timestamp responses.
-N, -M, --netmask
Check for ICMP Netmask responses.
-I, --info
Check for ICMP Info responses.
-R, --router
Check for ICMP Router Solicitation responses.
-v, --verbose
Increase the output verbosity.
-B, --debug

Target Specification

The simplest case is listing single hostnames or IP addresses on the command line. If you want to scan a subnet of IP addresses, you can append /mask to the hostname or IP address. mask must be between 0 (scan the whole Internet) and 32 (scan the single host specified). Use /24 to scan a class "C" address and /16 for a class "B". There is also a more powerful notation which lets you specify an IP address using lists/ranges for each element. Thus you can scan the whole class "B" network 192.168.*.* by specifying "192.168.*.*" or "192.168.0-255.0-255" or even "192.168.1-50,51-255.1,2,3,4,5-255". And of course you can use the mask notation: "192.168.0.0/16". These are all equivalent. If you use asterisks ("*"), remember that most shells require you to escape them with back slashes or protect them with quotes.

Examples:

The following example checks the first 16 addresses in the 192.168.1.0/24 netblock for all ICMP responses. The scan speed is increased by lowering the timeout value and setting the number of retries to 1:

> icmpscan -t 500 -r 1 192.168.1.0-16
192.168.1.0: Echo (From 192.168.1.17!)
192.168.1.0: Address Mask [255.255.255.0] (From 192.168.1.17!)
192.168.1.7: Echo
192.168.1.7: Timestamp [0x03ab2db0, 0x02d4c507, 0x02d4c507]
192.168.1.7: Address Mask [255.255.255.0]
192.168.1.8: Echo
192.168.1.8: Address Mask [255.255.255.0]
To display failed probes, increase the output verbosity:

> icmpscan -v 192.168.1.1
192.168.1.1: -- No response to Echo request --
192.168.1.1: -- No response to Timestamp request --
192.168.1.1: -- No response to Netmask request --
192.168.1.1: -- No response to Info request --
192.168.1.1: -- No response to Router Solicitation request --
Individual ICMP types can be checked for by listing their corresponding flags on the command line:

> icmpscan -v --echo --netmask 192.168.1.7
192.168.1.7: Echo
192.168.1.7: Address Mask [255.255.255.0]

ICPLD is a connection monitor which allows you to keep track of your network connection perfomance. It will log each occasion of broken networking.

icpld runs as a background process, and sends ICMP requests to an ip of your choice. When a reply isnt received within proper amount of time, it will consider the connection as unavailable and put a stamp in its log.

uIP TCP/IP stack provide TCP/IP connectivity to tiny embedded 8-bit microcontrollers, with maintained interoperability and RFC standards compliance.
uIP is an implementation of the TCP/IP protocol stack intended for small 8-bit and 16-bit microcontrollers.
uIP project provides the necessary protocols for Internet communication, with a very small code footprint and RAM requirements - the uIP code size is on the order of a few kilobytes and RAM usage is on the order of a few hundred bytes.
uIP is open source software written in the C programming language and the documentation and source code is free to use and distribute for both commercial and non-commercial use as long as proper credit is given (the full BSD-style license is here). It has been ported a wide range of 8-bit microcontrollers and is used in a large number of embedded products and projects (see the Links page for a few examples).
Main features:
- Well documented and well commented source code - nearly every other code line is a comment.
- Very small code size.
- Very low RAM usage, configurable at compile time.
- ARP, SLIP, IP, UDP, ICMP (ping) and TCP protocols.
- Includes a set of example applications: web server, web client, e-mail sender (SMTP client), Telnet server, DNS hostname resolver.
- Any number of concurrently active TCP connections, maxium amount configurable at compile time.
- Any number of passively listening (server) TCP connections, maximum amount configurable at compile time.
- Free for both commercial and non-commercial use.
- RFC compliant TCP and IP protocol implementations, including flow control, fragment reassembly and retransmission time-out estimation.
Enhancements:
- A new socket-like API, protosockets, was added.
- uIP now has rudimentary IPv6 support.
- A DHCP client was added and the Web server was rewritten with protosockets.
- Device driver structure was simplified.
- Many bugfixes were made in the TCP code.
- A uIP mailing list was started.

Shell over ICMP consists of two free and open source applications: one server and one client. Shell over ICMP project allows a user to connect to a remote shell daemon, by using ICMP protocol instead of classical TCP.
Entirely written in Python, soicmp is a working proof-of-concept to demonstrate that data can be transmitted across a network by hiding it in traffic that normally does not contain payloads.
How does it work?
The soicmp server is a daemon that must be started on the remote server. When the server receives a request from the client it looks into the packets payload. The payload must respect certain protocol rules. In detail the client must specify:
command
communication mode (echo|echo/reply)
authentication (y|n)
This is an example of a correct payload string sent by client to server:
$CMD ls -a $MODE echo/reply $PWD root2005 $END
If the payload matches with the server protocol specification then it will pipe the command to "/bin/sh" or "cmd.exe" and execute it. The server then reads the result from the pipe and sends it back to the client that will print it to stdout.
Moreover every client will send ICMP packets having id equal to the clients current process ID and will accept only ICMP replies having the same id value. This prevents output to be printed by other client instances running on the same workstation (this argument is also treated in the FAQs section).
Main features:
- Platform independent.
- Possibility to run soicmp daemon on multiple ethernet interfaces simultaneously handling multiple client connections.
- Possibility to specify the buffer size of outgoing packets.
- Client side source IP address spoofing.
- Remote client case-sensitive (plain texted) authentication.
- Possibility to select two communication types:
- One based on encapsulating command output in unique "one way" ICMP_ECHOREPLY (type 0) packets sent by server to client (see fig. 1).
- Another one that guarantees the correct packets delivering by using the request/response nature of ECHO and ECHOREPLY ICMP packet types (see fig.2)
- No listening sockets are listed by netstat or similar programs.

NetPacket::ICMP is a Perl module to assemble and disassemble ICMP (Internet Control Message Protocol) packets.

SYNOPSIS

use NetPacket::ICMP;

$icmp_obj = NetPacket::ICMP->decode($raw_pkt);
$icmp_pkt = NetPacket::ICMP->encode();
$icmp_data = NetPacket::ICMP::strip($raw_pkt);

NetPacket::ICMP provides a set of routines for assembling and disassembling packets using ICMP (Internet Control Message Protocol).

Methods

NetPacket::ICMP->decode([RAW PACKET])
Decode the raw packet data given and return an object containing instance data. This method will quite happily decode garbage input. It is the responsibility of the programmer to ensure valid packet data is passed to this method.

NetPacket::ICMP->encode()
Return an ICMP packet encoded with the instance data specified.
