Free over ip software for linux

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.

Verona is a portable VOIP toolkit based on oRTP, oSIP, eXosip, curl, and ffmpeg.
The toolkit includes a phApi module, which is a high level VOIP API that allows a developer to create voice/video over IP applications in a dozen lines of code.
It includes an example of a minimalistic SIP user agent that supports audio and video transmission. The toolkit is basically the VOIP engine used by the openwengo project.
Enhancements:
- This release optimizes and simplifies the build system.
- It adds support to cross-compile for ARM Linux.
- It adds support for transmission of DTMF in the SIP INFO packet.
- It is compatible with the latest version of Intels IPP.

FollowMeIP provides an IP address tracking utility.
FollowMeIP is a small client that allows you to retrieve the IP address of your machine over the Web. It works by periodically sending your IP address to the FollowMeIP server, from where you can retrieve it using a password.
It is ideal for people that are running servers on dynamic IP connections, or are away from home and want to access their machines.
Enhancements:
- The HTTP network functions now use straight TCP to ensure accurate IP reporting.

Operator is a complete Linux (Debian) distribution that runs from a single bootable CD and runs entirely in RAM.
The Operator contains an extensive set of Open Source network security tools that can be used for monitoring and discovering networks.
This virtually can turn any PC into a network security pen-testing device without having to install any software. Operator also contains a set of computer forensic and data recovery tools that can be used to assist you in data retrieval on the local system.
Starting with the 3.3 version of Operator, we have started completely from scratch by installing a basic Debian installation then adding the KNOPPIX functionality afterwards. This allowed us to have more control and understanding of what is on the CD.

Local IP Takeover provides network link redundancy within a single server that has multiple network interface cards (NICs) with each NIC connected to separate network switches.
If the primary NIC fails (i.e. it cannot ping its default gateway), the "service" IP (the IP that the outside world connects to) will automatically float to the secondary NIC and a specially crafted ARP (utilizing send_arp) will be broadcast on the local network, thereby instructing all other hosts to update their local ARP cache.
The result is minimal service downtime. Plus, no manual intervention is required in the event that a network card, cable, or switch breaks.
Enhancements:
- The initialization step is more robust and it doesnt allow lipt to abort its execution. Instead, lipt should recover to a sane state eventually (within less than half a minute under normal circumstances).
- Other minor fixes were made.

The Vovida SIP stack is an implementation of the protocol defined in RFC 2543, the Session Initiation Protocol, which can be used to initiate voice connections (phone calls) over IP networks.

It offers an object-oriented C++ API as well as sample applications demonstrating its use.

NetAddr::IP is a Perl module that can manage IPv4 and IPv6 addresses and subnets.

SYNOPSIS

use NetAddr::IP qw(
Compact
Coalesce
Zero
Ones
V4mask
V4net
:aton
:old_storable
:old_nth
);

my $ip = new NetAddr::IP loopback;

print "The address is ", $ip->addr, " with mask ", $ip->mask, "n" ;

if ($ip->within(new NetAddr::IP "127.0.0.0", "255.0.0.0")) {
print "Is a loopback addressn";
}

# This prints 127.0.0.1/32
print "You can also say $ip...n";
* The following four functions return ipV6 representations of:
:: = Zeros();
FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF: = Ones();
FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:: = V4mask();
::FFFF:FFFF = V4net();
* To accept addresses in the format as returned by inet_aton, invoke the module as:
use NetAddr::IP qw(:aton);
* To enable usage of legacy data files containing NetAddr::IP objects stored using the Storable module.
use NetAddr::IP qw(:old_storable);
* To compact many smaller subnets (see: $me->compact($addr1, $addr2,...)
@compacted_object_list = Compact(@object_list)
* Return a reference to list of NetAddr::IP subnets of $masklen mask length, when $number or more addresses from @list_of_subnets are found to be contained in said subnet.
$arrayref = Coalesce($masklen, $number, @list_of_subnets)
